2 Overview
The cell handover strategy is required in WCDMA to implement mobility management of
RRC connections due to UE mobility. It is also required to balance traffic among cells to
lower traffic in heavily-loaded cells. Service connections must not be interrupted and
QoS must be guaranteed during handover.
In the process of a handover:
If a UE retains the radio connection with the current cell while establishing a radio
connection in a new cell, the handover is called soft handover.
If the new and current cells belong to the same Node B during a soft handover, the
handover is called softer handover.
Handover Control Feature Guide
ZTE Confidential Proprietary 15
If a UE needs to disconnect with the current cell before setting up a link
(synchronization) with a new cell (that is, the new and current links do not co-exist),
the handover is called hard handover.
A transient interruption will occur to UE transmission and reception duringa hard
handover. Therefore, the hard handover may affect the QoS.
Handovers may also be classified into intra-frequency handover, inter-frequency
handover and inter-RAT handover by different cell frequency features or access
technologies before and after a handover. A UE in connection can only receive
single-frequency service data, but soft/softer handover requires a UE to retain a radio link
with several cells concurrently, so the soft/ softer handover must be an intra-frequency
handover. However, a handover between the cells of the same frequency may not be a
soft/softer handover. It may be a hard handover. The inter-frequency/inter-RAT handover
is surely a hard handover because of different carrier frequencies/frequency bands.
Normally, a UE has only one set of receiver and transmitter, so activating compressed
mode is necessary for inter-frequency and inter-RAT measurement. The following table
lists the correspondence between handover and compressed mode.

A handover generally involves three steps: measurement, handover decision and
handover implementation. Measurement is the prerequisite for a handover, handover
decision is the core of a handover and handover implementation is the process of
implementing a handover decision. This document describes these three steps to
illustrate the relevant algorithms, and contains the following contents:
Handover Control Feature Guide
ZTE Confidential Proprietary 16
2.1 ZWF21-03-001 Soft/Softer Handover
In soft handover, a UE maintains several radio links with different Node Bs, while in softer
handover, a UE concurrently maintains radio links with several cells in a Node B, and
these cells are also known as macro diversity.
Soft/softer handover only occurs in intra-frequency cells. Compared with the hard
handover, the soft/softer handover has the following features:
Soft and softer handovers are seamless handovers and no service will be
interrupted during handover.
Macro diversity gain: When a UE maintains radio links with several cells, the
receiver may enhance the accuracy of data reception and link receiving quality and
lower the transmit power of all links by combining the signal receiving results of
several links.
The best cell where a UE registers may establish a radio connection with the UE in
time to lower the transmit power of the UE.
In view of these features, for intra-frequency handover, soft and softer handovers are
conducted whenever possible, a hard handover is only conducted when the soft/softer
handover is unavailable.
2.2 ZWF21-03-002 Intra-Frequency Hard Handover
Hard handover is a typical handover mechanism in which a UE needs to disconnect with
the current cell before setting up a link (synchronization) with a new cell (that is, the new
and current links do not co-exist). The intra-frequency hard handover is only conducted
when the soft/softer handover is unavailable.
2.3 ZWF21-03-003 Inter-Frequency Hard Handover
Inter-frequency hard handover means a UE in connection state hands over from one cell
on one frequency of UTRAN to another cell on another frequency.
Handover Control Feature Guide
ZTE Confidential Proprietary 17
The factors triggering an inter-frequency hard handover include radio quality, cell load,
and moving speed of the UE.
Inter-frequency hard handover triggered by radio quality: An inter-frequency
measurement is initiated when the quality of the frequency where the UE is currently
located worsens, and then the UE is handed over to the frequency with better quality
based on the inter-frequency measurement result. The quality of the carrier frequency
where the UE is currently located is measured according to the following four standards
(For details, see Chapter 5 “Inter-Frequency Handover Strategy”):
PCPICH quality of the cell in the current serving carrier frequency.
Uplink Block Error Rate (BLER) of the Dedicated Channel (DCH).
Uplink transmit power of DCH.
Downlink transmit power of DCH.
Inter-frequency hard handover triggered by cell load: When the load of a cell on the
current frequency is too heavy, the system switches partial services of the cell to an
adjacent cell on another frequency.
Inter-frequency hard handover triggered by moving speed of the UE: It is mainly used on
the HCS network. UEs with quick moving speed are carried in macro cells and those with
slow moving speed in micro cells for appropriate traffic distribution in cells, making full
use of system resources and enhancing system performance.
For non-double-receiver terminals in WCDMA, compressed mode must be initiated for
inter-frequency measurement. However, initiation of compressed mode has impact on
the performance of both the system and the UE. Therefore, compressed mode must not
be initiated unless absolutely necessary (for example, when the quality of the current
serving carrier frequency worsens).
2.4 ZWF21-03-004 Inter-RAT Mobility (GSM)
Inter-RAT mobility refers to the mobility management conducted when a UE switches
from one UMTS to another one. It only applies to the mobility management for UEs that
Handover Control Feature Guide
ZTE Confidential Proprietary 18
switch from UTRAN to RATx (the mobility management from RATx to UTRAN belongs to
the strategy of RATx).
This feature requires the UE to support both WCDMA and RATx. Moreover, the RATx
also needs to offer related features to support inter-RAT handover. The features required
by WCDMA are described below.
WCDMA-to-GSM handover supports the following services:
Conversational services
Videophone service fallback to ordinary voice service. (3GPP R6)
PS transferred to GPRS/GERAN
For a WCDMA-to-GSM handover combining CS and PS RAB, the system first switches
CS services to GERAN first, and then the RNC releases the PS on lu interface upon
receiving the context request message from the CN. The UE activates the PS service on
GERAN upon the release of CS services.
In WCDMA:
UTRAN-to-GERAN mobility of CS services in connected mode is implemented
through a CS service handover procedure.
UTRAN-to-GERAN mobility of PS services in CELL_DCH state is implemented
through a cell reselection procedure (PS service handover) triggered on the network
side.
UTRAN-to-GERAN mobility of PS services in CELL_FACH /URA_PCH state is
implemented through a cell reselection procedure triggered by UE.
Load-based UTRAN-to-GERAN handover of PS services in CELL_FACH state is
implemented through a cell reselection procedure triggered on the network side.
Inter-system mobility in connected mode must be accompanied by an inter-system
relocation.
The factors triggering a WCDMA-to-GSM handover include radio quality and cell load.
Handover Control Feature Guide
ZTE Confidential Proprietary 19
Inter-RAT handover triggered by radio quality: An inter-RAT measurement is initiated
when the quality of the frequency where the UE is currently located worsens and
inter-frequency measurement initiation conditions cannot be met or the quality of other
frequencies is also poor, and then the UE is handed over to the cell of RATx based on
the inter-RAT measurement result. The quality of the frequency where the UE is currently
located is measured according to the following four standards (For details, see “7 GSM
Inter-RAT Handover Policy”):
PCPICH quality of the cell in the current serving carrier frequency.
Uplink Block Error Rate (BLER) of the Dedicated Channel (DCH).
Uplink transmit power of DCH.
Downlink transmit power of DCH.
Inter-RAT handover triggered by cell load: When the load of a cell in the current UTRAN
system is too heavy, the system switches partial services of the cell to an adjacent cell in
GERAN.
For non-double-receiver terminals in WCDMA, compressed mode must be initiated for
inter-RAT measurement. However, initiation of compressed mode has impact on the
performance of both the system and the UE. Therefore, compressed mode must not be
initiated unless absolutely necessary (for example, when the quality of the current
serving carrier frequency worsens).
2.5 ZWF21-03-006 Inter-RNC Handover with Iur Support
This feature supports maintaining communication continuity in the case of a UE in
CELL_DCH state moving among inter-RNC cells. The Iur interface is configured between
different RNCs to ensure that a UE maintains the current connection with the CN when
being handed over in the coverage areas of different RNCs. There is no need to trigger
an SRNS relocation, so that the effect of SRNS relocation on service quality is reduced.
Handover Control Feature Guide
ZTE Confidential Proprietary 20
2.6 ZWF21-03-008 Directed Signalling Connection
Re-establishment
This feature enables the RNC to allow the UE with ongoing PS services to trigger a
DSCR procedure to interoperate with the RNC that cannot support the SRNS relocation
procedure.
2.7 ZWF21-03-009 Coverage Based Handover
This feature allows the system to utilize the measurement report to judge the quality of
radio links and thus to perform handovers to guarantee the service quality for users in the
case of changing network coverage conditions.
The RNC can control the UE to perform the intra-frequency, inter-frequency and
inter-RAT measurement and judge the radio link quality according to the measurement
result of event-triggered reports to trigger various handovers: soft/softer handover,
intra-frequency hard handover, inter-frequency hard handover and inter-RAT handover.
The RNC can also be configured with different handover parameters for different
services.
2.8 ZWF21-03-010 Compressed Mode
For non-double-receiver terminals in WCDMA, compressed mode must be initiated for
inter-RAT/inter-frequency measurement. When compressed mode is used, some
timeslots are specially used for inter-frequency/inter-RAT measurement instead of data
transmission during transmission and reception.
2.9 ZWF21-03-011 Neighboring Cells Priorities
This feature can be used to configure different priorities for different cells in the adjacent
cell list. It allows a UE to hand over to an adjacent cell of high priority with a higher
success rate to improve the handover performance of the system.

ZTE Confidential Proprietary 21
2.10 ZWF21-03-012 Handover Based on Dedicated
Downlink Transmit Power
This feature enables handovers based on the dedicated downlink transmit power, and
applies to the following scenario: The signal of pilot frequency is acceptable, but the
dedicated downlink transmit power has become very high, requiring the UE to hand over
to an inter-frequency or inter-RAT adjacent cell.
2.11 ZWF21-03-012 Handover Based on Dedicated
Uplink Transmit Power (UE)
This feature enables handovers based on the dedicated uplink transmit power, and
applies to the following scenario: The signal of pilot frequency is acceptable, but the
dedicated uplink transmit power has become very high, requiring the UE to hand over to
an inter-frequency or inter-RAT adjacent cell to avoid large interference on other users.
2.12 ZWF21-03-013 Quality-Based Handover
This feature enables handovers based on the uplink BLER and applies to the following
scenario: The signal of pilot frequency is acceptable, but the uplink of the UE is very poor
due to uplink interference or other reasons. In the event of the outer loop power control
failure, the UE needs to be handed off to an inter-frequency or inter-RAT adjacent cell as
quick as possible to avoid call drops.
2.13 ZWF21-03-020 SRNS Relocation
This feature supports that a UE in CELL_DCH state transfers services to a new RNC
when moving among adjacent RNC cells. When there is no Iur interface between RNCs,
SRNS relocation can maintain service continuity. When there is an Iur interface between
RNCs, SRNS relocation triggered timely after a handover via Iur is completed can reduce
the transmission resource consumption at the Iur interface.
Handover Control Feature Guide
ZTE Confidential Proprietary 22
2.14 ZWF21-03-022 IMSI-based Handover
The scope of authorized cells is configured based on the IMSI information on the network
side. The IMSI information is resolved through the CommonID on lu interface during a
service setup or handover, and the UE is not allowed to access or to be handed over to
unauthorized cells.
2.15 ZWF21-03-023 Inter-RAT PS Handover (GSM)
This feature shortens PS service interruption when there is a handover between
inter-RAT adjacent cells. With this feature, PS service continuity is enhanced, especially
for the real-time packet service with higher QoS requirements, and therefore user
experience is improved.
2.16 ZWF21-03-024 DTM Handover
This feature guarantees service continuity for UEs that have CS and PS combined
services during inter-RAT movement. It improves user experience.
When a UE with CS and PS services simultaneously moves between inter-RAT adjacent
cells, these CS and PS services are handed over to an inter-RAT cell in parallel via DTM
mechanism.
2.17 ZWF21-03-025 NACC
The PS service will be interrupted when it is handed over to GERAN via cell reselection
procedure, which leads to bad user experience. Network Assisted Cell Change (NACC)
reduces the duration of UE inter-RAT cell reselection procedure by sending system
information to the RNC in advance.

2.18 ZWF21-03-026 Target Cell Load Based Inter-RAT
Handover
This feature enables the RNC to get load information of 2G or EUTRAN adjacent cells.
The RNC selects an adjacent cell with a lower load as target cell when the UE is handed
over to GSM or EUTRAN from UMTS.
2.19 ZWF21-05-022 Handover Strategy Based on Service
Type
This feature determines whether and when services can be handed over to GSM based
on the service handover attribute in the RAB assignment request message.
This feature determines whether services can be handed over to EUTRAN based on the
EUTRAN service handover attribute in the RAB assignment request message.
2.20 ZWF21-03-014 Enhanced Iur-g
The feature supports the enhanced Iur-g interface between GERAN BSC and 3G RNC. It
enables the RNC to get capability and load information of 2G cells. By employing the
interface, inter-RAT load balance can be achieved, inter-RAT handover success ratio is
improved and handover delay is decreased.
2.21 ZWF21-03-110 UTRAN<->LTE PS Handover
Strategy
The feature supports UTRAN<->LTE PS Handover when the signal quality is poor, so
that the continuity of PS services between UTRAN and LTE is ensured.
Handover Control Feature Guide
ZTE Confidential Proprietary 24
2.22 ZWF21-03-120 Single Radio Voice Call Continuity
(SRVCC)
This feature ensures the continuity of voice services between UTRAN and LTE during
inter-RAT handovers. The RNC can transform the voice call from the VoIP/IMS packet
domain to the legacy circuit domain.
2.23 ZWF21-03-101 CS Fallback (CSFB)
This feature ensures the continuity of voice services between UTRAN and EUTRAN.
When CSFB traffic initializes a PS handover from EUTRAN to UTRAN, the
corresponding CS traffic can be set up in UTRAN later.
2.24 ZWF21-03-050 Handover Optimization in
Weak-Coverage
This feature supports enhancing handover performance. In the weak-coverage area, the
system decides the link quality of the target cell that is suitable for adding a new link into
macro diversity or serving cell change, and only when the quality is above the threshold,
the corresponding soft handover procedure or serving cell change procedure can be
initiated. This can increase the handover success rate, decrease call drop rate, and
improve RAN network performance and service experience.
2.25 ZWF23-03-001 HS-DSCH Serving Cell Change
The HS-PDSCH has only one serving cell. During an intra-system soft handover, if an
HS-PDSCH exists before and after the handover when the best cell changes (triggered
by 1D event), an HS-PDSCH serving cell change is triggered. If there is an HS-PDSCH
before and after a hard handover, the HS-PDSCH serving cell must change.
Handover Control Feature Guide
ZTE Confidential Proprietary 25
2.26 ZWF23-03-002 HS-DSCH handover to/from DCH
When a UE roams between HSDPA cell and R99 cell, a migration between the
HS-DSCH and DCH occurs to maintain service continuity.
This feature can be used for intra-RNC handover or inter-RNC handover.
2.27 ZWF23-03-003 HS-DSCH Inter-RAT Reselection
This feature ensures service continuity when HSDPA users moving from a UMTS cell to
a GSM cell. When an HSDPA user with services carried on HS-DSCH channel need be
handed over from a UTMS cell to a GSM cell, the RNC can hand over the UE to connect
the GSM cell directly without falling HS-DSCH back to DCH before the inter-RAT
handover.
2.28 ZWF23-03-004 HSDPA Soft/Softer Handover of
A-DPCH
The HSDPA service supports soft/softer handovers of associated DPDCH/DPCCH,
where the policy is identical with that of a common soft/softer handover.
2.29 ZWF23-03-005 HSDPA over Iur
This feature enables data transmission on HS-DSCH to be retained without falling
HS-DSCH back to DCH when an HSDPA subscriber is handed over between different
RNCs over Iur.
2.30 ZWF25-03-001 HSUPA Soft/Softer Handover
The HSUPA service supports soft/softer handovers of associated DPDCH/DPCCH,
where the policy is identical with that of a common soft/softer handover.
Handover Control Feature Guide
ZTE Confidential Proprietary 26
2.31 ZWF25-03-002 E-DCH Serving Cell Change Inside
Active Set
The E-DCH has only one serving cell, so if an E-DCH exists before and after an
intra-system soft handover when the best cell changes (triggered by 1D event), a change
of the E-DCH serving cell is triggered. If there is an E-DCH before and after a hard
handover, the E-DCH serving cell must change.
2.32 ZWF25-03-003 E-DCH Intra-frequency Hard
Handover
The procedure of an E-DCH intra-frequency hard handover is similar with a DCH
intra-frequency hard handover. If the target cell supports HSUPA, an intra-frequency
hard handover is conducted with an E-DCH serving cell change, otherwise, E-DCH will
fall back to DCH.
2.33 ZWF25-03-004 E-DCH Inter-frequency Hard
Handover
The procedure of an E-DCH inter-frequency hard handover is similar with a DCH
inter-frequency hard handover. If the target cell supports HSUPA, an inter-frequency
hard handover is conducted with an E-DCH serving cell change, otherwise, E-DCH will
fall back to DCH.
2.34 ZWF25-03-005 HSUPA over Iur
This feature enables data transmission on E-DCH to be retained without falling E-DCH
back to DCH when an HSUPA subscriber is handed over between different RNCs over
Iur.

2.35 ZWF25-03-012 HSUPA Inter-RAT Reselection
This feature ensures service continuity when HSUPA users moving from a UMTS cell to
a GSM cell. When an HSUPA user with services carried on E-DCH channel need be
handed over from a UTMS cell to a GSM cell, the RNC can hand over the UE to connect
the GSM cell directly without falling E-DCH back to DCH before the inter-RAT handover.
3 Compressed Mode Strategy
3.1 Introduction to Compressed Mode
For non-double-receiver terminals in WCDMA, compressed mode must be initiated for
inter-RAT/inter-frequency measurement. When compressed mode is used, some
timeslots are specially used for inter-frequency/inter-RAT measurement instead of data
transmission during transmission and reception.. The following two ways can generate
compressed mode frames:
1 Halving of Spreading Factor (SF)
By halving the SF, the bandwidth can be increased so that some timeslots in one
radio frame can be specially assigned for inter-frequency/inter-RAT measurement
and some can be specially assigned for data transmission. This transmission
strategy is generally used in services that have high requirements for delay and
minimum data rate, for example, CS- and S-type PS data services.
2 Higher Layer Scheduling
The higher layer scheduling is in nature a strategy in which the higher layer adjusts
and controls the data transmission rate. Some timeslots in a radio frame can be
specially assigned for inter-frequency/inter-RAT measurement and some can be
specially assigned for data transmission while the bandwidth remains unchanged.
This strategy is generally used for non-real-time services that have low
requirements for delay, for example, I/B-type PS data services.
Handover Control Feature Guide
ZTE Confidential Proprietary 28
After compressed mode is initiated, the GAP used for transmission/reception
(measurement) can be placed either within one radio frame or between two radio frames,
see Figure 3-1.
Figure 3-1 Transmission Gap (TG) Position
In the protocol TS 25.212, the Transmission Gap Length (TGL) can be set to 3, 4, 5, 7,
10 and 14 timeslots. The TG may start from any timeslot in a frame. When the TG spans
two consecutive frames, each frame at least has 8 non-compressed timeslots.
Figure 3-2 shows the parameters involved in compressed mode. The Transmission Gap
Pattern Sequence (TGPS) consists of consecutive TG patterns (TG pattern 1). One or
two TGs are defined in a TG pattern. The starting timeslot No. of the first TG is
determined by the parameter TGSN. The number of timeslots between starting timeslots
of two TGs in the TG pattern is determined by the parameter TGD. The first TGL is
determined by the parameter TGL1, and the second by the parameter TGL2. If the
parameter TGD is not defined, it means that there is only one TG in the TG pattern. The
length of a TG pattern is determined by the parameter TGPL1. The number of repeats of
a TG pattern is determined by the parameter TGPRC.

3.2 Compressed Mode Strategy
If the UE capability message indicates that compressed mode is required during an FDD
inter-frequency or inter-RAT measurement procedure, compressed mode is initiated
upon the initiation of an inter-frequency or inter-RAT measurement. Compressed mode
must be disabled in either of the following scenarios: 1) Deleting the inter-frequency
measurement while keeping the inter-RAT measurement disabled. 2) Deleting the
inter-RAT measurement while keeping the inter-frequency measurement disabled.
As described in the previous section, the strategy of halving of SF does not affect the
real-time rate of services, while that of higher layer scheduling reduces the real-time rate
of services. For RT services, only the first strategy can be used to ensure delay and
transmission rate. For NRT services, both the first and second strategies can be used
because of their low requirements for delay and rate.
The above rules only apply to DCH/DCH. For HS-DSCH or E-DCH, only higher layer
scheduling is supported. An exception is that if SF/2 method is configured but has not
been activated, and currently the services are using UL SF4 and compressed mode
need to be activated, the RNC can modify it to higher layer scheduling method.
Handover Control Feature Guide

Compressed mode of all services on ZTE networks use identical parameters as listed
below:
Table 3-1 Parameters of Compressed Mode
GSM Adjacent Cell
Measurement
FDD Adjacent Cell Measurement
TGSN 4 (Slots) 3 (Slots)
TGL1 7 (Slots) 7 (Slots)
TGD Not configured Not configured
TGPL1 8 (Frames) 8 (Frames)
As shown in the table, when the TGSN is 4 (GSM) or 3 (FDD), TGL1=7, all GAPs of
compressed mode on ZTE networks in the same radio frame (one radio frame in FDD
has 15 slots), that is, single frame mode is uniformly used.
For all commercial terminals in the current market, compressed mode can be initiated
directly when services are carried on HS-DSCH. Whether HS-DSCH falls back to DCH
before the initiation of compressed mode is controlled through the parameter
HsdpaCmAssoMode. If the parameter value is “Serial”, HS-DSCH needs to fall back to
DCH before the initiation of compressed mode. If the parameter value is “Parallel”,
compressed mode is initiated directly.
Moreover, whether E-DCH falls back to DCH before the initiation of compressed mode is
controlled through the parameter HsupaCmAssoMode (UHspa). If the parameter value is
“Serial”, E-DCH needs to fall back to DCH (the reconfigured target rate is min (max
(DRBC lowest of rate grades, GBR), MaxBR), for DRBC rate grades, see ZTE UMTS
DRBC Algorithm Feature Guide) before the initiation of compressed mode. If the
parameter value is “Parallel”, compressed mode is initiated directly. Figure 3-3 shows
the procedure in which E-DCH falls back to DCH before the initiation of compressed
mode.

For a part of commercial terminals in the current market, compressed mode cannot be
initiated when services are carried on E-DCH. Whether a UE supports “Initiate
compressed mode for services carried on E-DCH” is not specified in 3GPP. Therefore,
when services are carried on E-DCH, the RNC does not know whether a UE can “Initiate
compressed mode for services carried on E-DCH”. To deal with these UEs, when
HsupaCmAssoMode is set to “Parallel” and the current services involve HSUPA services,
the RNC executes “„the safeguarded strategy after the initiation of HSUPA parallel
compressed mode fails” as follows:
When the RNC forwards the Measurement Control message to a UE for initiating
compressed mode and the UE returns the Measurement Control Failure message, the
RNC will reconfigure E-DCH to DCH before initiating compressed mode. Afterwards, if
the UE need switch from DL HS-DSCH/UL DCH to DL HS-DSCH/UL E-DCH based on
traffic volume measurement reports during a call process, the RNC will not allow it if the
UE is in compressed mode.
In the procedure of a service setup, state transition, call re-establishment and relocation
from other RNCs to the local RNC, the RNC will configure accompanying compressed
Handover Control Feature Guide
ZTE Confidential Proprietary 32
mode by default through RADIO BEARER SETUP/RADIO BEARER
RECONFIGURATION/PHYSICAL CHANNEL RECONFIGURATION to UE and RADIO
LINK SETUP REQUEST/RADIO LINK RECONFIGURATION to Node B. Figure 3-4
shows the procedure of configuring accompanying compressed mode. For state
transitions from CELL_PCH or CELL_FACH to CELL_DCH, GResPara14 is introduced
to control whether the RNC will configure accompanying compressed mode. If
GResPara14 is set to “1”, accompanying compressed mode will be configured, otherwise
the RNC will not configure accompanying compressed mode, so that the signaling
message length of the radio interface can be decreased, and dedicated compressed
mode will be configured when compressed mode needs to be activated.
In the event that compressed mode needs to be initialized (for example, event 2D is
reported), the neighboring cell relation changes or the best cell changes (for example,
the best cell changes from a cell that does not support inter-frequency or inter-RAT
handover to a cell that only supports inter-frequency handover), if compressed mode has

3.3 Compressed Mode Configuration Strategy via RNC
For inter-RNC handovers, some vendors do not support accompanying compressed
mode. To guarantee the normal procedure via IUR, ZTE performs the following two
special strategies:
The DRNC does not support accompanying compressed mode
RncFeatSwitchBit9 indicates whether the neighboring RNC supports accompanying
compressed mode. If compressed mode has not been activated on the SRNC side, the
method of configuring compressed mode is decided by RncFeatSwitch Bit9. If
compressed mode has been activated already, RncFeatSwitch Bit9 is invalid, and the
SRNC must configure accompanying compressed mode and activate it for the DRNC.
Handover Control Feature Guide
ZTE Confidential Proprietary 34
DRNC conditionally supports accompanying compressed mode
Some vendors do not support inter-frequency and inter-RAT accompanying compressed
mode simultaneously. CompMdCfgStra (ULogicalRnc) indicates the strategy of
accompanying compressed mode configuration. When inter-frequency and inter-RAT
neighboring cells exist, if the value of CompMdCfgStra (ULogicalRnc) is “0”, the RNC
configures two types of accompanying compressed mode (inter-frequency and inter-RAT). If
the value of CompMdCfgStra(ULogicalRnc) is “1”, the RNC configures only one type of
accompanying compressed mode (inter-frequency or inter-RAT) based on the specific
value of IfOrRatHoSwch(UCelInfoFDD) (For the details of IfOrRatHoSwch, see 5.10
Inter-Frequency and Inter-RAT Measurement Choice).
For inter-RNC handovers, some vendors have compatibility problems of compressed
mode.
To guarantee the normal procedure via IUR, ZTE performs the following special strategy:
The DRNC does not allow the compressed mode command via Iur to activate
compressed mode
Some vendors do not allow the compressed mode command via Iur to activate
compressed mode, RncFeatSwitchBit17 indicates the strategy for this situation. When
CS traffic and Iur link exist, if RncFeatSwitchBit17 is “0”, the DRNC does not activate
compressed mode even when needed (if compressed mode is already activated, the
DRNC does not take account of RncFeatSwitchBit17). When CS traffic and Iur link exist,
if RncFeatSwitchBit17 is “1”, the DRNC activates compressed mode when needed.
4 Intra-Frequency Handover Strategy
Intra-frequency handover refers to a handover performed between cells of the same
frequency in UTRAN. An intra-frequency handover can be triggered based on EcNo or
RSCP measurement through the parameter IntraMeasQuan (UUtranCellFDD).
Intra-frequency handover is the measurement-based handover. Intra-frequency
measurement contains active set measurement, monitored set measurement and
detected set measurement.
Handover Control Feature Guide
ZTE Confidential Proprietary 35
The active set refers to a set of cells retaining a radio connection with the UE.
The monitored set refers to a set of cells retaining no radio connection with the UE but
requesting a measurement by sending an intra-frequency measurement control message
to the UE.
The detected set refers to a set of intra-frequency cells other than those in the active set
and monitored set.
4.1 Intra-Frequency Measurement
When conducting an intra-frequency measurement, the UE needs to implement layer 3
filtering for the measurement results to avoid measurement fluctuations, and then make
event decisions and report by using filtered values. The layer 3 filter formula is as follows:
nnn MaFaF 1)1(
Where,
Fn-1 refers to the result of the last filter.
Fn refers to the result of the current measurement filter.
Mn refers to the current measurement result.
a = 1/2(k/2)
refers to the filter coefficient calculated based on the filter factor K (FilterCoeff
(For event-triggered measurements, if the measurement quantity is EcNo, this parameter
is obtained from UIntraEcNoEvMeas; if the measurement quantity is RSCP, this
parameter is obtained from UIntraRscpEvMeas. For detected set measurements, if the
measurement quantity is EcNo, this parameter is obtained from UIntraEcNoEvMeasForD;
if the measurement quantity is RSCP, this parameter is obtained from
UIntraRscpEvMeasForD. For periodical measurements, if the measurement quantity is
EcNo, this parameter is obtained from UIntraEcNoPrdMeas; if the measurement quantity
is RSCP, this parameter is obtained from UIntraRscpPrdMeas)).
Handover Control Feature Guide
ZTE Confidential Proprietary 36
4.1.1 Introduction to Intra-Frequency Measurement
Intra-frequency measurement refers to a measurement performed on intra-frequency
cells. It only supports event-triggered reporting. The event-triggered reporting method
means the UE judges whether intra-frequency events are met based on the quality
measurement result of the cell PCPICH. If so, it reports intra-frequency events (including
such information as event ID and target cell) to the RNC.
A series of intra-frequency measurement events are defined in 3GPP as the judgment
and trigger criteria for intra-frequency handover.
Event 1A: A Primary CPICH enters the Reporting Range. It can be used for adding cells
to the active set.
Event 1B: A Primary CPICH leaves the Reporting Range. It can be used for deleting cells
from the active set.
Event 1C: A Non-active Primary CPICH becomes better than an active Primary CPICH. It
can be used for replacing the cell with bad quality in the active set.
Event 1D: The best cell changes. It can be used for soft/softer handover, intra-frequency
hard handover and inter-frequency load balance.
4.1.2 Measurement Control Method Related to Active Set and Monitored
set
4.1.2.1 Measurement Setup
Intra-frequency measurement parameters are configured for the UE and intra-frequency
measurements are initiated through the measurement control setup message in the
following cases:
An RRC connection is set up and enters CELL_DCH state.
CELL_FACH -> CELL_DCH.
Relocation to the current RNC from other systems or RNCs.
Handover Control Feature Guide
ZTE Confidential Proprietary 37
An intra-frequency measurement is set up again after an intra-system hard handover
(including intra- or inter-frequency hard handover).
4.1.2.2 Measurement Modification
If an intra-frequency measurement is enabled, an intra-frequency measurement
modification is triggered in the following cases:
A change of the adjacent cell list may trigger a modification of intra-frequency
measurement to modify adjacent cell parameters after a soft handover.
After the best cell changes (Event 1D), a change of intra-frequency measurement
parameters will trigger a modification of intra-frequency measurement to update
handover parameters.
If a service is added or deleted, a change of intra-frequency measurement
parameters will trigger a modification of intra-frequency measurement to update
handover parameters.
4.1.2.3 Measurement Deletion
Upon receiving an exceptional intra-frequency measurement report (for example, the
measurement report belongs to a non-existent measurement task), or before making a
decision about the relocation triggered by a soft handover, the RNC will voluntarily
release the corresponding intra-frequency measurement. When the RNC sends a
MEASUREMENT CONGROL RELEASE message for a measurement ID, the time stamp
will be recorded. If the RNC receives a measurement report for the ID, the report will be
compared between the current time and recorded time. If the difference between the
current time and recorded time exceed the threshold TResndMeaCtrlRel (URncFunction)
configured, the MEASUREMENT CONTROL RELEASE message will be resent.
Otherwise, this measurement report is ignored.
4.1.2.4 Parameter Configuration Strategies
Intra-frequency event parameter configuration:
Handover Control Feature Guide
ZTE Confidential Proprietary 38
There are seven intra-frequency measurement events (1A, 1B, 1C, 1D, 1E, 1F and
1J) in total. The number of events configured depends on the parameter
MeasEvtNum (If the measurement quantity is EcNo, this parameter is obtained from
UIntraEcNoEvMeas. If the measurement quantity is RSCP, this parameter is
obtained from UIntraRscpEvMeas), and the intra-frequency events configured
depends on the parameter MeaEvtId (If the measurement quantity is EcNo, this
parameter is obtained from UIntraEcNoEvMeas. If the measurement quantity is
RSCP, this parameter is obtained from UIntraRscpEvMeas). MeaEvtId is defined
through array, and the dimension of array is equal to MeasEvtNum, which is seven
at most.
Handover parameter configuration strategy in macro diversity:
All measurement parameters are cell-based. In macro diversity, the measurement
parameters configured in the best cell will be used as handover parameters. If the
best cell changes, the measurement parameters need to be updated at the same
time.
For inter-RNC handovers, if there is an SRNC cell in the active set, the
measurement parameters of the best cell in the SRNC will be used as handover
parameters, and if there is no SRNC cell in the active set, the measurement
parameters of the last SRNC cell in the active set will be used as handover
parameters.
Configuration of several sets of handover parameters:
The intra-frequency handover parameters can be separately configured based on
the measurement quantity, measurement report mode and service bearer type. In
this way, several sets of measurement parameters are necessitated for different
purposes. The categories are as follows:
Measurement quantity
IntraMeasQuan(UUtranCellFDD) (CPICH EcNo or RSCP)
Measurement reporting mode
Handover Control Feature Guide
ZTE Confidential Proprietary 39
Periodical or event-triggered reporting. Only event-triggered reporting is
supported, and the following parameters related to periodical reporting are
invalid: UIntraEcNoPrdMeas (UIntraEcNoPrdMeas), UIntraRscpPrdMeas
(UIntraRscpPrdMeas), PrdRptAmount (If the measurement quantity is EcNo,
this parameter is obtained from UIntraEcNoPrdMeas. If the measurement
quantity is RSCP, this parameter is obtained from UIntraRscpPrdMeas) and
PrdRptInterval (If the measurement quantity is EcNo, this parameter is
obtained from UIntraEcNoPrdMeas. If the measurement quantity is RSCP, this
parameter is obtained from UIntraRscpPrdMeas).

Note: When a new cell is set up, the value of intialHoCelSelScene (UIntraMeasProfile)
(0:Outdoor Scene, 1:High-Mobility Outdoor Scene, 2:Indoor Scene, 3:Subway/tunnel
Scene) is determined according to the actual cell scene (indicated by
HoCelSelScene(UUtranCellFDD)), and the available intra-frequency measurement
profile corresponding to intialHoCelSelScene is configured for the cell.
Before intra-frequency handover parameters are obtained,
profileId(UIntraMeasProfile) of the cell is found based on
Handover Control Feature Guide
ZTE Confidential Proprietary 41
ref1UintraMeasProfile(UUtranCellFDD), and then, in UintraMeasProfile
configuration items, the next level managed object is obtained according to the
current measurement application type: For event-triggered measurements,
“Intra-frequency Measurement Configuration Related to Traffic Category Object
ID(UIntraMeasSrvSpec)” is selected. For periodical measurements or detected set
tracing applications, “Intra-frequency Measurement Configuration Unrelated to
Traffic Category Object ID (UIntraMeasNoSrvSpec)” is selected.
In the managed object decided above, “Intra-Frequency Measurement
Configuration No. (IntraMeasCfgNo)” is found based on “Traffic Category
(srvCategory(UIntraMeasSrvSpec))” and “Measurement Quantity((intraMeasQuan)”.
Finally, the corresponding intra-frequency handover measurement parameters are
found. The details are as follows:
(1). For event-triggered measurements:
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UIntraEcNoEvMeas.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UIntraRscpEvMeas.
(2). For periodical measurements:
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UIntraEcNoPrdMeas.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UIntraRscpPrdMeas.
Note: Periodical reporting is not supported currently, so the measurement
parameters related to the managed object UIntraEcNoPrdMeas or
UIntraRscpPrdMeas are invalid.
(3). For detected set measurements:
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UIntraEcNoEvMeasForD.
Handover Control Feature Guide
ZTE Confidential Proprietary 42
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UIntraRscpEvMeasForD.
Correspondence between other parameters that need to be filled into the
intra-frequency measurement control message
Measurement Quantity and Measurement Report Criteria are automatically filled by the
system based on IntraMeasCfgNote.
For the cells of the neighbor RNC, if the value of Primary CPICH Power Configuration
Tag (PcpichPwrPre(UExternalUtranCellFDD)) is TURE, the cell information of the
intra-freq measurement should include the Primary CPICH Power for this cell. Otherwise
the cell information of the intra-freq measurement should not include the Primary CPICH
Power for this cell.
4.1.3 Neighboring Cells Configuration
During the neighboring cells configuration, the adjacent cell list used for reselection in
non-CELL_DCH state and for handovers in CELL_DCH state can be configured
separately. During handovers, target cells are selected by neighboring cells configuration
state (StateMode (UUtranRelation)). When the UE is in macro diversity state, the
neighboring cell list is a combination of neighboring cell lists of each cell in the active set,
so the number of intra-frequency neighboring cells may exceed 32, which is the
maximum number specified by the protocol. If the number of intra-frequency neighboring
cells exceeds 32, some cells must be deleted to ensure that there are only 32
intra-frequency neighboring cells. With minimal impact on the UEs in the active set, these
dropped cells are those with poorer signal quality or remoter geographical location.
Therefore, each intra-frequency neighboring cell is configured with a priority.
4.1.3.1 Cell Priority Configuration
The OMCR configuration parameter MeasPrio (UUtranRelation) defines the priority of
adjacent cells with three values (0: High priority; 1: Medium priority; 2: Low priority). The
value of MeasPrio (UUtranRelation) must be set by the network planning engineer based
on the existing network conditions (for example, adjacent cell quality and geographical
location of adjacent cell). Figure 4-2 shows the cell priority configuration based on the
Handover Control Feature Guide
ZTE Confidential Proprietary 43
geographical location of adjacent cells. For example, for the configuration of cells
adjacent to the innermost gray cell, there are three layers of adjacent cells surrounding
the gray cell, and they are differentiated from one another with yellow (0: Top priority),
blue (1: Medium priority) and red (2: Low priority).
Figure 4-2 Cell Priority Configuration
Source Cell
Priority 0
Priority 1
Priority 2
4.1.3.2 Strategy for Adjacent Cells Exceeding 32
As specified in the protocol, the maximum number of adjacent cells is 32 (including the
source cell). When the UE is in macro diversity state, the total number of intra-frequency
adjacent cells in the macro diversity may exceed 32, so some strategies are required to
control the number within 32, including:
Priority combination strategy
If a cell is adjacent to several cells in the active set, that is, the priority levels configured
for this cell may vary, the priority levels of this cell are combined and the highest priority
is taken as the priority of the cell.
Sorting strategy
If the total number of adjacent cells in the active set is 32, the system prioritizes them in
descending order and places the cells in excess of 32 into the adjacent cell reserve list,
Handover Control Feature Guide
ZTE Confidential Proprietary 44
which can buffer at most 64 truncated intra-frequency cells.
The priority levels of adjacent cells in the intra-frequency adjacent cell list will be updated
whenever Event 1A/1B/1C/1D is triggered. If Event 1B is triggered and the number of
adjacent cells is less than 32, the system selects cells from the reserve list in descending
order of priority and places them into the intra-frequency adjacent cell list. The number of
cells that can be selected: min (32 – Number of existing cells in the intra-frequency
adjacent cell list, Number of cells in the reserve list).
4.2 Handling Mechanism for Periodical Reporting of
Intra-Frequency Handover Measurement
The periodical reporting is that a report of intra-frequency measurement result is sent by
the UE periodically based on the periodical report interval (PrdRptInterval (If the
measurement quantity is EcNo, this parameter is obtained from UIntraEcNoPrdMeas. If
the measurement quantity is RSCP, this parameter is obtained from UIntraRscpPrdMeas)
and the amount of periodical reports (PrdRptAmount (If the measurement quantity is EcNo,
this parameter is obtained from UIntraEcNoPrdMeas. If the measurement quantity is
RSCP, this parameter is obtained from UIntraRscpPrdMeas)) configured by RNC. The
RNC judges intra-frequency handover events in accordance with the intra-frequency
event rule defined in the protocol by referring to the cell quality periodically reported by
the UE. If several decision conditions are concurrently met, the RNC will process events
in the sequence of 1D, 1A, 1C and 1B. Currently, periodical reporting mode is not
supported.
A long interval set in periodical reporting mode may result in call drop due to handover
delay. Therefore, it is recommended to set the interval to a low value. However, setting a
short interval will increase the signaling load of radio interface and easily lead to
signaling congestion, so event-triggered reporting mode is generally preferred.

4.3 Intra-Frequency Handover Decision
4.3.1 Event 1A-Triggered Handover
Event 1A means the quality of a certain cell outside the active set ameliorates. Upon
receiving Event 1A, the RNC adds the corresponding target cell into the active set to
enhance the gain of macro diversity. When the cell meets the conditions in the following
formula, the UE reports Event 1A to the RNC:

The meanings of all parameters are described as follows:

measurement quantity is EcNo, this parameter is obtained from UIntraEcNoEvMeasForD,
if the measurement quantity is RSCP, this parameter is obtained from

NA: Refers to the number of cells other than the best cell in the active set.
MBest: Refers to the measurement of the best cell in the active set.
W: Refers to the weight (W[MAX_INTRA_MEAS_EVENT] (For event-triggered
measurements, if the measurement quantity is EcNo, this parameter is obtained from

is EcNo, this parameter is obtained from UIntraEcNoEvMeasForD, if the measurement
quantity is RSCP, this parameter is obtained from UIntraRscpEvMeasForD)) of the best
cell to the rest cells in the active set in evaluation standards.
From the formula, it can be concluded that the probability of triggering Event 1A can be
increased by either increasing R1a (Event 1A meets the reporting range conditions) or
decreasing H1a (Decision hysteresis range. Otherwise, probability of triggering Event 1A
can be reduced.
Event 1A supports event-triggered periodical reporting, that is, once Event 1A meets the
reporting range of quality standards, the UE reports Event 1A periodically
(EvtRptInterval[MAX_INTRA_MEAS_EVENT] (For event-triggered measurements, if the

reporting conditions or the reporting times reach the maximum allowed times

There is a restriction on the number of radio links in active set, so Event 1A will not be
reported once the number of cells in the active set reaches the threshold

4.3.2 Event 1B-Triggered Handover
Event 1B indicates the quality deterioration of a certain cell in the active set. Upon
receiving Event 1B, the RNC may delete the cell from the active set. When the cell meets
the conditions in the following formula, the UE reports Event 1B to the RNC:

cell to the rest cells in the active set in evaluation standards.
From the above formula, it can be concluded that the probability of triggering Event 1B
can be decreased by either increasing R1b (Event 1B meets the reporting range
conditions) or decreasing H1b (Decision hysteresis range). Otherwise, the probability of
triggering Event 1B can be increased.
4.3.3 Event 1C-Triggered Handover
Event 1C indicates that the quality of a cell in the non-active set is better than that of a
cell in the active set. Upon receiving Event 1C, the RNC may replace the cell in the active
set with a cell in the non-active set to obtain better gain of macro diversity. When the cell
meets the conditions in the following formula, the UE reports Event 1C to the RNC:

From the above formula, it can be concluded that the probability of triggering Event 1C
can be decreased by increasing H1c (decision hysteresis range). Otherwise, the
probability of triggering Event 1C can be increased.
Event 1C supports event-triggered periodical reporting, that is, once Event 1C meets the

To ensure the gain of macro diversity, the reporting of Event 1C is only allowed when the
number of cells in the active set reaches a certain threshold (RplcActThr
[MAX_INTRA_MEAS_EVENT] (If the measurement quantity is EcNo, this parameter is
obtained from UIntraEcNoEvMeas. If the measurement quantity is RSCP, this parameter
is obtained from UIntraRscpEvMeas)).
4.3.4 Event 1D-Triggered Handover
Event 1D indicates that the quality of a cell inside or outside the current active set is
better than the best cell in the current active set, that is, the best cell changes in the
active set. The following operations can be triggered upon the reception of Event 1D:
A cell is added into the active set (The cell outside the active set reports Event 1D
and the number of links in the active set does not reach the maximum limit).
The cell with poor quality in the active set is replaced (The cell outside the active set
reports Event 1D but the number of links in the active set reaches the maximum
limit).
The serving cell changes (for HS-DSCH/E-DCH).
When the cell meets the conditions in the following formula, the UE reports Event 1D to
the RNC:
/2HCIOLogM10CIOLogM10 1dBestBestNotBestNotBest
MNotBest: Refers to the measurement of the to-be-evaluated cell inside or outside the
active set.
CIONotBest: Refers to the offset of the to-be-evaluated cell inside the active set
(CellIndividualOffset (UUtranCellFDD)) or outside the active set (CellIndivOffset
(UUtranRelation)) in relation to other cells.
CIOBest: Refers to the offset of the to-be-evaluated cell in the active set in relation to other
cells (CellIndividualOffset (UUtranCellFDD)).
MBest: Refers to the measurement of the to-be-evaluated cell in the active set.
Handover Control Feature Guide
ZTE Confidential Proprietary 51
H1d: Refers to Event 1D reporting hysteresis (Hysteresis [MAX_INTRA_MEAS_EVENT]
(For event-triggered measurements, if the measurement quantity is EcNo, this parameter
is obtained from UIntraEcNoEvMeas, if the measurement quantity is RSCP, this
parameter is obtained from UIntraRscpEvMeas. For detected set measurements, if the
measurement quantity is EcNo, this parameter is obtained from UIntraEcNoEvMeasForD,
if the measurement quantity is RSCP, this parameter is obtained from
UIntraRscpEvMeasForD)).
From the above formula, it can be concluded that the probability of triggering Event 1D
can be decreased by increasing H1d (decision hysteresis range). Otherwise, the
probability of triggering Event 1D can be increased.
4.3.5 CIO Configuration Strategy
The Cell Individual Offset (CIO) defined by 3GPP is used to control the difficulty of event
triggering. The tendency of handover can be also controlled by the CIO in actual
scenarios.
The CIO principles of the target cell are described as follows.
If there is a neighboring relationship between the target cell and the best cell, the
CIO is CellIndivOffset (For a UTRAN cell, this parameter is obtained from
UUtranRelation. For a GSM cell, this parameter is obtained from UExternalGsmCell)
selected from the best cell. If there is not any neighboring relationship between the
target cell and the best cell, the CIO is the minimum absolute value of
CellIndivOffset selected from the cells in the active set. If there is not any
neighboring relationship between the target cell and the cells in the active set, the
CIO is set to zero.
If the target cell is the best cell, the CIO is CellIndividualOffset (UUtranCellFDD)
selected from the serving cell.
If the best cell changes, the RNC will inform UEs to update the CIO.
Handover Control Feature Guide

4.3.6 Time-To-Trigger Mechanism Used to Control Event Report
If a to-be-evaluated cell meets the reporting range or threshold of a certain event, the
condition must be met within a period of time (TrigTime[MAX_INTRA_MEAS_EVENT]
(For event-triggered measurements, if the measurement quantity is EcNo, this parameter
is obtained from UIntraEcNoEvMeas, if the measurement quantity is RSCP, this
parameter is obtained from UIntraRscpEvMeas. For detected set measurements, if the
measurement quantity is EcNo, this parameter is obtained from
UIntraEcNoEvMeasForD., if the measurement quantity is RSCP, this parameter is
obtained from UIntraRscpEvMeasForD)) before the reporting of this event to avoid the
intra-frequency event misreport due to the fluctuation of radio quality. For example, if a
cell meets the reporting range of Event 1A, the UE only reports Event 1A only if the cell
quality meets this reporting range condition within
TrigTime[MAX_INTRA_MEAS_EVENT], see Figure 4-3.

4.3.7 Criterion of Being in the Same Active Set Based on Cell Type
Before adding a cell into the active set, the current service and the ability of the target cell
should be judged. If the target cell supports the current service or channel (For R99 cells,
supporting the channel associated with HSDPA services also counts.), the cell is allowed
to join the active set.
Handover Control Feature Guide
ZTE Confidential Proprietary 53
1. If the current service is a DCH service, R99, R5+R99, and R6+R5+R99 cells can be
in the same active set.
2. If the current service is an HS/D service, R99, R5, R6+R5, R5+R99, and
R6+R5+R99 cells can be in the same active set.
3. If the current service is an HS/E service, R6+R5 and R6+R5+R99 cells can be in the
same active set.
4. If HS and DCH services both exist, the criterion is as that of HS services.
4.3.8 Processing of Intra-Frequency Events
Processing of Event 1A
Links are added into the active set if the number of links in the DCH active set is
less than 3. Event 1A will not be processed if the total number of links in the active
set reaches the maximum limit.
If a link to be added into the active set is rejected in Event 1A, the handover
punishment timer (5s) is initiated, so that Event 1A reported by this rejected cell will
not be processed until the timer expires.
If the cell reporting Event 1A is the target cell traced by the detected set, no link will
be added into the active set. For details, see Detected set Tracing.
If the measurement report contains several target cells, the cell with best quality
(EcNo) will be selected as the target cell to be added in the active set.
If the cell reporting Event 1A is the cell of the SRNC side, and the parallel softer
handover switch of Iub and Uu ParallelSoftHO is “open”, the RL ADD procedure of
the Iub interface and the ACTIVE SET UPDATA procedure of the Uu interface will
be processed in parallel.
Processing of Event 1B
The link of the related cell is deleted based on Event 1B reported by the UE.
Handover Control Feature Guide
ZTE Confidential Proprietary 54
If the measurement report contains several target cells, the cell with worst quality
(EcNo) will be selected as the target cell to be deleted from the active set.
Processing of Event 1C
The cell is replaced if the radio links in the active set are equal to 3.
If a link to be added into the active set is rejected in Event 1C, the handover
punishment timer is initiated, so that Event 1C reported by this rejected cell will not
be processed until the timer expires.
The parallel processing of the Iub and Uu interfaces when adding a radio link in
softer handover is the same as that of Event 1A.
Processing of Event 1D
If the cell triggering Event 1D is an intra-frequency adjacent cell outside the active
set, and if the criterion described in “4.3.14 Scenarios of Intra-Frequency Hard
Handover” is fulfilled, the RNC will perform an intra-frequency hard handover.
If the cell triggering Event 1D is an intra-frequency adjacent cell outside the active
set, and if the DCH active set is full, Event 1D will be processed as Event 1C. If the
DCH active set is not full, Event 1D will be processed as Event 1A. If event 1A or 1C
fails due to admission control failure, the RNC will perform an intra-frequency hard
handover.
If the cell triggering Event 1D is inside the active set, the best cell in the active set
changes.
4.3.8.1 Intra-frequency Handover Optimization in Weak Coverage
When the UE adds a new link into macro diversity or the serving cell changes, if the link
quality is not good enough, the UE is easy to drop because of processing the reported
intra-frequency events. In response, the RNC executes “Quality Judgement Strategy of
Target Cell”, as described below.
For 1A, 1C events:
Handover Control Feature Guide
ZTE Confidential Proprietary 55
(1). EnhanceHoSwch (URncFunction) is set to “1: On”.
(2). AddNRLSHOSwch (UCelInfoFDD) is set to” 1: on”.
(3). The UE reports Event 1A or Event 1C.
(4). The quality of the target cell: CPICH EcNo< IntraHoEcNoThrd (URncFunction) or
CPICH RSCP< IntraHoRscpThrd (URncFunction).
If these conditions are met, the RNC will not process Event 1A and Event 1C reported by
the UE.
For 1D event:
(1). EnhanceHoSwch (URncFunction) is set to “1: On”.
(2). CResPara5 (UCelInfoFDD) is set to” 1: on”.
(3). The UE reports Event 1D.
(4). The quality of the target cell: CPICH EcNo< IntraHoEcNoThrd (URncFunction) or
CPICH RSCP< IntraHoRscpThrd (URncFunction).
If these conditions are met, the RNC will not process Event 1D reported by the UE.
Moreover, during an intra-frequency handover, the timer TWAITACTSETUPCMP
(URncFunction) for waiting for the Active Set Update Complete message is initiated after
the Active Set Update message is sent from RNC to the UE. When the timer expires and
the Active Set Update Complete message is not received, if the conditions described
below are met, the RNC will still decide the active set update succeed. Otherwise, the
RNC will decide the update fails.
(1). EnhanceHoSwch (URncFunction) is set to “1: On”.
(2). The user plane confirms that the UE has received the Active Set Update message.
4.3.8.2 Special Events Handling via IUR for CS+PS
For CS+PS services via IUR, call drops may occur due to incompatibility of different
Handover Control Feature Guide
ZTE Confidential Proprietary 56
vendors‟ equipment. In response, the SRNC executes “Special Events Handling via IUR
for CS+PS” if the following conditions are met:
(1). RncFeatSwitchBit15 is set to “0”.
(2). Concurrent services exist and include CS+PS services, being indexed to the
configuration of Multi RAB Including CS and PS.
If these conditions are met, the SRNC will not process Event 1A/1C/1D of the DRNC's
cells.
4.3.8.3 Strategy for Soft Handover OD Switch Configuration in the Signaling Stage
In response to the incompatibility that may occur when equipment from different vendors
is interconnected via IUR, the RNC adds the following special strategy in the signaling
stage:
If the SRNC receives 1A/1B/1C/1D events from the DRNC‟s cells in the signaling stage,
the SRNC will not process these events when RncFeatSwitchBit16 is “0”, and the SRNC
will process these events when RncFeatSwitchBit16 is “1”.
4.3.8.4 Special Events Handling via IUR for CS
In response to the incompatibility that may occur when equipment from different vendors
is interconnected via IUR, for CS services, the SRNC executes “Special Events Handling
via IUR for CS” if the following conditions are met:
(1). RncFeatSwitchBit15 is set to “0”.
(2). CsIntraEvtSwch (UCelInfoFDD) is set to “1”.
(3). Only CS services, being indexed to the configuration of RT RAB Including Voice.
If these conditions are met, the SRNC will not process Event 1A/1C/1D of the DRNC's
cells.
Handover Control Feature Guide
ZTE Confidential Proprietary 57
4.3.9 Detected set Handover
The detected set handover is controlled through the parameter DetSetHoSwch
(UUtranCellFDD). If the detected set handover is enabled, and the number of adjacent
cells exceeds 32, the RNC needs to instruct the UE to submit the measurement report of
the detected set in the measurement control. If the target cell in the detected set event
reported by the UE is a cell in the adjacent cell reserve list described in 4.1.3.2 Cell
Dropping Strategy for Over 32 Adjacent Cells, the RNC processes the cell in the
detected set in the same way as it does in the monitored set, that is, making a handover
decision.
4.3.9.1 Related Measurement Procedure of Detected set Handover
(1). If the detected set handover (DetSetHoSwch (UUtranCellFDD)) of the best cell is
enabled and there are over 32 adjacent cells, a detected set measurement will be
initiated. The initiation strategy is changing “1A Triggering condition 2” into
“Detected set cells and monitored set cells”, and “Reporting cell status” into “Report
all active set cells + cells within monitored set and/or detected set on used
frequency”, that is, performing measurement reporting of active set, monitored set
and detected set concurrently by sharing the same set of handover measurement
parameters.
(2). If the detected set handover (DetSetHoSwch (UUtranCellFDD)) of the best cell is
disabled or there are less than 32 adjacent cells, the initiation strategy is changing
“1A Triggering condition” into “Monitored set cells” and “Reporting cell status” into
“Report cells within active set and/or monitored set cells on used frequency”, That is,
only reporting the monitored set instead of the detected set.
4.3.9.2 Related Parameter Configurations
The RNC only performs handovers for the detected set measurement reported by the
adjacent cells exceeding 32. The processing of the measurement report triggered by
these cells is actually consistent with that triggered by the monitored set. Therefore, the
detected set and monitored set share the same set of measurement configurations.
Handover Control Feature Guide
ZTE Confidential Proprietary 58
4.3.10 Detected Set Tracing
The detected set tracing is used in network planning and optimization to judge whether
there is any adjacent cell that is not configured based on the statistical report. The
purpose of detected set tracing measurement differs from that of handover measurement,
so the measurement parameters used for detected set tracing are separately configured
in the OMCR (The parameters of detected set tracing is irrelevant to service type, which
means all sorts of services will be indexed by “Not Related to Service Type “in service
type (srvCategory (UIntraMeasSrvSpec)), see 4.1.2.4 Parameter Configuration
Strategies.).
4.3.10.1 Measurement Procedure of Detected Set Tracing
1. The measurement of detected set tracing is controlled through the detected set
tracing task in the performance measurement of the OMCR. A detected set
measurement is started after a detected set tracing task is created and initiated if
the parameter NbrCellMonSupInd (ULogicalRnc) is 1. During the configuration of
the measurement control, “Triggering condition 2” is set to “Detected set cells”, and
“Reporting cell status” is set to “Report cells within detected set on used frequency”.
2. The measurement parameters of the detected set are indexed to the cell, and the
parameters of the best cell will be selected in macro diversity state. If the
parameters of the best cell are different from those used by the UE, the
measurement information needs to be modified through the measurement control
message.
3. After the detected set tracing task stops, the detected set tracing is disabled and the
related measurement task is released.
4.3.11 Processing of the Rx-Tx Time Difference of a UE in Macro Diversity
When a UE is in macro diversity, the uplink transmitting time of the UE is not adjusted.
The initial downlink channels can be correctly demodulated, but the downlink receiving
time changes along with the movement of the UE or with the drifting of the clock between
Node Bs. Therefore, the downlink receiving time may fall out of the time window of the
UE transmitting time T0 ± 148 chips, and consequently the UE cannot correctly
Handover Control Feature Guide
ZTE Confidential Proprietary 59
demodulate one or multiple downlink channels, causing the degradation of UE downlink
quality or even call drop. For this reason, the 3GPP protocols have defined the UE
internal measurement events 6F and 6G for UE Rx-Tx time difference measurement:
6F event: The UE Rx-Tx time difference for a link in the active set is greater than an
absolute threshold.
6G event: The UE Rx-Tx time difference for a link in the active set is less than an
absolute threshold.
The rlRefTimeAjtSw (ULogicalRnc) parameter controls the policy of the UE Rx-Tx
time difference in macro diversity. If the switch is on, the RNC removes the
corresponding link from macro diversity when the UE reports a 6F or 6G event
(indicating that the downlink receiving time falls out of the UE transmitting time
window). If the switch is off, the function is disabled.
4.3.11.1 Related Measurement Procedure
1. When the radio link reference time adjustment switch of the best cell
(rlRefTimeAjtSw (ULogicalRnc)) is on and the number of links in macro diversity
changes from one to multiple, the 6F/6G measurement parameters will be issued to
the UE. Furthermore, the parameter TxRxTDThres
[MAX_UE_INTER_MEAS_EVENT](URlEvtRttUeInt) indicates the UE Rx-Tx time
difference reporting threshold in chips in event 6F/6G.
MAX_UE_INTER_MEAS_EVENT is configured by MeasEvtNum (URlEvtRttUeInt).
The parameter TrigTime [MAX_UE_INTER_MEAS_EVENT] (URlEvtRttUeInt)
indicates the period of time during which the event conditions have to be satisfied
before a measurement report is sent.
2. The internal measurement parameters (6F/6G) of the UE are configured per cell
according to the index, and are subject to the parameters of the best cell. When the
UE internal measurement parameters are obtained, profileId (UUeIntMeasProfile) of
the cell is found based on refUUeIntMeasProfile (UUtranCellFDD), and then
according to the current measurement purpose “UE Rx-Tx Time Difference Event
Measurement for RL Timing Adjustment”, the managed object URlEvtRttUeInt is
obtained from UUeIntMeasProfile configuration items. Finally, the internal
Handover Control Feature Guide
ZTE Confidential Proprietary 60
measurement parameters are obtained from URlEvtRttUeInt. For a UE on which the
internal measurement (6F/6F) function is enabled in macro diversity, if the 6F/6G
event parameters of the best cell are different from the parameters issued to the UE,
the parameter configuration of the UE will be modified through measurement
control.
The correspondence between other parameters that need to be filled in the UE internal
measurement control message and OMCR configuration is described as follows:
UE internal measurement configuration index ueIntMCfgNo(URlEvtRttUeInt)
Measurement report transmission mode MeasRptTrMod(URlEvtRttUeInt)
Filter coefficient FilterCoeff(URlEvtRttUeInt)
UE internal event identity MeaEvtId(URlEvtRttUeInt)
3. When the number of links in macro diversity changes from multiple to one and the
internal measurement function (6F/6G) is enabled on the UE, a release of internal
measurement will be triggered on the UE.
4.3.12 IUB Transmission Bandwidth Limitation Strategy
When a network is constructed, there may be a shortage of Iub transmission resources.
An access of a high-rate UE may lead to inaccessibility of numbers of other users to the
network. To prevent some individual high-rate UEs from affecting the communication
quality in large scale, it is necessary to limit the maximum rate of these UEs in the cell.
For intra-RNC DCH users, the parameters RtMaxUlRateDch / RtMaxDlRateDch (for RT
services) and NrtMaxUlRateDch / NrtMaxDlRateDch (for NRT services) are used to limit
the maximum rates of uplink and downlink DCHs respectively. For intra-RNC E-DCH
users, the maximum rates are limited by the parameters RtMaxrateEdch (for RT services)
and NrtMaxRateEdch (for NRT services).
For inter-RNC DCH users, the parameters RtMaxUlRateDchD / RtMaxDlRateDchD (for
RT services) and NrtMaxUlRateDchD / NrtMaxDlRateDchD (for NRT services) are used
to limit the maximum rates of uplink and downlink DCHs respectively. For E-DCH users,
the maximum rates are limited by parameters RtMaxRateEdchD (for RT services) and
NrtMaxRateEdchD (for NRT services). If the related parameters are not configured in the
neighboring cells, the restriction decision does not take effect.
Handover Control Feature Guide
ZTE Confidential Proprietary 61
Processing of adding a radio link in active set
For DCH users, if the GBR of DCH users is higher than the rate limitation
RtMaxUlRateDch / RtMaxDlRateDch of the new neighboring cell, it does not add a radio
link. Otherwise, it adds a radio link.
For EDCH users, if the rate of E-DCH users is higher than the E-DCH rate limitation
RtMaxRateEdch / NrtMaxRateEdch of the new neighboring cell, it reduces E-DCH
Maximum Bitrate by radio link reconfiguration, and then adds the corresponding
neighboring cell into macro diversity.
Processing of deleting a radio link in active set
For DCH users, a radio link is deleted from macro diversity. If the UE rate is less than the
DCH rate limitation of the cells in macro diversity, the RNC will perform RB
reconfiguration.
For E-DCH users, a radio link is deleted from macro diversity. If the UE rate is less than
E-DCH rate limitation of the cells in macro diversity, the RNC will perform RL
reconfiguration to enhance E-DCH Maximum Bitrate.
4.3.13 Decision on Support-CS64k Traffic of Target Cell
For some special scenarios where accessing or handing over CS64K traffic is not
expected in a cell, the parameters Cs64kSwitch and AdjCs64Switch are used to control
whether a cell supports CS64k traffic in the SRNC and DRNC respectively. When CS64k
traffic is restricted in a cell, ingoing, outgoing and handover of CS64k traffic are
forbidden.
When a handover happens in intra-RNC cells and CS64k traffic is covered, if
Cs64kSwitch in the target cell is closed and the UE allows CS64k to fall back to
AMR12.2k, then CS64k falls back to AMR12.2k and the UE performs the related
handover. Otherwise, the UE does not perform any handover.
When a handover happens in inter-RNC cells and CS64k traffic is covered, if
AdjCs64kSwitch in the target cell is closed and the UE allows CS64k to fall back to
AMR12.2k, then CS64k falls back to AMR12.2k and the UE performs the related
Handover Control Feature Guide
ZTE Confidential Proprietary 62
handover. Otherwise, the UE does not perform any handover. If a DRNC cell
reported has no configuration relationship with SRNC cells, the cell supports CS64k
by default.
4.3.14 Scenarios of Intra-Frequency Hard Handover
When soft handover cannot be performed in intra-frequency adjacent cells for some
reasons, intra-frequency hard handover can guarantee service continuity. The scenarios
where a soft/softer handover is unavailable (An intra-frequency hard handover must be
used) include:
Adding a new link fails in a soft handover when a 1A or 1C event is triggered.
The intra-frequency measurement report excludes the OFF and TM of the target
cell.
The lur interface between RNCs is unavailable in the case of intra-frequency
handover.
The types of the target and source cells are different, for example, the UE is handed
over from a DCH-capable cell to an HSPA-capable cell.
The signal RB is carried on HS-DSCH in the active cell, while F-DPCH is not
supported in the adding target cell
The capability of the target cell is not consistent with that of the source cell,
including:
The UE uses transmit diversity in an active set cell, but the target cell does not
support transmit diversity.
The UE uses multi-user detection in an active set cell, but the target cell does not
support multi-user detection
The UE uses DTX-DRX in an active set cell, but the target cell does not support the
capability
Uplink 16QAM is configured but the target cell does not support it
A TTI 2ms service is set up in the source cell, but the target cell does not support
The transmission delay TimeDelay(UIubLink) reported during an intra-frequency
handover for the Node B where the neighboring cell of the current RNC resides is
Handover Control Feature Guide
ZTE Confidential Proprietary 63
inconsistent with the transmission delay of the cells in the current active set, or the
transmission delay ATimeDelay(UExternalUtranCellFDD) reported during
intra-frequency handover for the neighboring cell that is a DRNC cell is inconsistent
with the transmission delay of the cells in the current active set.
There are two synchronization modes for intra-frequency hard handover: Timing
re-initialised and Timing-maintained, which are controlled by the parameter
gRESPARA47.bit14 (URncFunction).
4.3.15 Disposal Strategy of Intra-Frequency Events in Buffer
If the RNC receives measurement events and discards them in unsteady state, it may
miss handover opportunities, and radio links with good signal quality may be not added
into the active set while radio links with poor signal quality may be still in the active set.
So it needs to cache measurement reports in buffer in unsteady state and then dispose
of such measurement reports while the RNC enters steady state. In unsteady state, the
RNC needs to combine the received measurement reports. The strategy is described as
follows:

If inter-frequency cells between RNCs are adjacent and the lur interface is unavailable,
the hard-handover-triggered SRNS relocation is performed. The procedure is described
as follows:
The SRNC sets up a radio link at the DRNC through an lu interface relocation, and then
reconfigure the UE to a cell of the DRNC through a relocation. Upon receiving the
reconfiguration response message from the UE, the DRNC informs the CN to complete
Handover Control Feature Guide
ZTE Confidential Proprietary 71
the relocation and changes into SRNC. The CN then releases the resources of the UE at
the original SRNC through the lu interface release command.
5 Inter-Frequency Handover Strategy
The inter-frequency handover is a feature in which the UE is handed over from one
frequency of UTRAN to another one. It can either be a handover based on the
inter-frequency measurement, or a blind handover based on ShareCover (Overlap or
Covers). The measurement-based handover cannot trigger a blind handover based on
shared coverage. The blind handover between cells with shared coverage can only be
triggered by such functions as load control and load balancing.
The prerequisite for measurement-based inter-frequency handovers is that the UE
performs a quality measurement of non-working frequencies. For an inter-frequency
measurement in CELL_DCH state, the UE needs to initiate compressed mode unless it
has double-receiver. Compressed mode has a great impact on both the resource
utilization (for example, downlink power and uplink interference) and UE (for example,
transmit power and battery consumption), so an inter-frequency measurement is only
initiated when the radio quality of the current serving carrier is poor, which can be
evaluated through four measurement quantities: Uplink BLER, UE uplink transmit power,
transmit power of downlink and inter-frequency measurement (quality measurement
performed by the UE for PCPICH). Upon receiving the inter-frequency measurement
results from the UE, the RNC makes a decision about inter-frequency handover, and
hands over the UE to the target frequency and cell carried in the measurement results.
The blind handover based on ShareCover (Overlap or Covers) is controlled through the
coverage indication (ShareCover UUtranRelation)) in the adjacent cell configuration
relation. If the radio quality of a cell is good, then that of another cell that has
ShareCover(Overlap or Covers) relation with it must also be good, which means
forecasting the radio quality of another cell that has ShareCover (Overlap or Covers)
relation with a cell based on the radio quality of this cell. Whether the ShareCover
(Overlap or Covers) relation exists among cells is determined by the network planner
based on cell coverage (Only those cells with completely the same coverage can be
called cells with shared coverage, and inter-frequency cells with shared coverage
generally share a site and antenna feeder. If a cell completely contains the coverage of
Handover Control Feature Guide
ZTE Confidential Proprietary 72
another cell, the relation between them is called ‟Covers‟). The blind handover based on
ShareCover (Overlap or Covers) is primarily used in load control, load balancing and
handover based on moving speed.
In the load balancing mechanism, if the load of the target cell for access or
handover is too heavy, you can access or hand over the service into another less
loaded cell that has ShareCover (Overlap or Covers) relation with the target cell.
In the load control mechanism, if the load of the current cell is too heavy, you can
forcedly hand over partial services into another less loaded cell that has
ShareCover (Overlap or Covers) relation with the target cell.
In a handover based on the moving speed, when the UE changes from a low to a
high moving speed, the UE can be directly handed over from a micro cell into a
macro cell that contains this micro cell.
5.1 Inter-Frequency Measurement
When conducting an inter-frequency measurement, the UE needs to implement layer 3
filter for the measurement results to avoid measurement fluctuations, and then make
event decisions and reports by using filtered values. The layer 3 filter factor is FilterCoeff
(If the measurement is an event-triggered measurement and the measurement quantity
is EcNo, for Event 2D/2F used for the EUTRAN system, this parameter is obtained from
UInterEcNoEvMeasforE. For Event 2D/2F used for the GSM system, this parameter is
obtained from UInterEcNoEvMeasforG. For inter-frequency measurement events used
for the UTRAN system, this parameter is obtained from UInterEcNoEvMeasforU. If the
measurement is an event-triggered measurement and the measurement quantity is
RSCP, for Event 2D/2F used for the EUTRAN system, this parameter is obtained from
UInterRscpEvMeasforE. For Event 2D/2F used for the GSM system, this parameter is
obtained from UInterRscpEvMeasforG. For inter-frequency measurement events used
for the UTRAN system, this parameter is obtained from UInterRscpEvMeasforU. If the
measurement is a periodical measurement and the measurement quantity is EcNo, this
parameter is obtained from UInterEcNoPrdMeas. If the measurement quantity is RSCP,
this parameter is obtained from UInterRscpPrdMeas). For the inter-frequency
measurement formula, see “Intra-frequency Measurement”.

5.1.1 Introduction to Inter-Frequency Measurement
The inter-frequency measurement contains radio quality measurement of both working
carrier frequency and non-working carrier frequency. It can be performed based on either
EcNo or RSCP or both measurement quantities, depending on the parameter
NonIntraMeasQuan (UUtranCellFDD). Only event-triggered reporting is supported. The
event-triggered reporting means the UE judges whether inter-frequency events are met
based on the quality measurement result of the non-working carrier frequency PCPICH.
If so, it reports inter-frequency events (including such information as event ID and the
target cell) to the RNC.
A series of inter-frequency measurement events are defined in 3GPP as the judgment
and trigger criteria for inter-frequency handovers.
The inter-frequency handover events are described as follows:
Event 2A: The best carrier frequency changes.

measurement events used for the UTRAN system, this parameter is obtained from
UInterRscpEvMeasforU)) before the reporting of this event to avoid an inter-frequency
event misreport due to the fluctuation of radio quality.
5.1.2 Inter-Frequency Measurement Control Method
Among all inter-frequency measurement events, Event 2D and Event 2F only involve
measurements of working carrier frequencies, so compressed mode is not required
during a measurement and an extra overhead will not be brought to both the UE and the
RNC. Compressed mode can be enabled and disabled based on the definition of 2D/2F.
If there is any inter-frequency/Inter-RAT adjacent cell during a service setup, the RNC
will configure Event 2D, Event 2F and intra-frequency events to the UE. The following
measurement setup, modification and deletion apply to inter-frequency measurement
events other than Event 2D and Event 2F.
5.1.2.1 Measurement Setup
An inter-frequency measurement is only set up only when the inter-RAT measurement is
not initiated, and it can be triggered in either of the following scenarios:
1. The radio quality of the current serving carrier frequency deteriorates and there are
inter-frequency adjacent cells that have no ShareCover (Covers) relation (judged
Handover Control Feature Guide
ZTE Confidential Proprietary 79
through ShareCover(UUtranRelation)) with the current serving cell and the UE
supports the radio frequency band of these neighboring cells.
2. The UE meets the slow moving conditions and there is a micro cell with higher HCS
level in the coverage of the current cell (based on moving speed).
The “Radio Quality Deterioration of Current Serving Carrier Frequency” can be judged
through any of the following four indexes:
Uplink BLER: The uplink BLER value exceeds a certain threshold (1.25%) and the
Sirtarget value (real-time measurement result) reaches the maximum value of SIR
(ULMaxSIR) configured in the OMCR. The BLER is measured and judged by the
RNC.
Uplink transmit power of UE: The transmit power of the UE exceeds a certain
threshold (100%, in relation to the maximum transmit power of the UE). The uplink
transmit power is measured by the UE and reported to the RNC through the internal
measurement report 6A/6B. The threshold parameter of Event 6A and Event 6B
(txPowerThres(UHoEvtTPUeInt)) is a delta value relative to min(UE maximum
transmitted power, uplink DPCH maximum transmission power).
Downlink transmit power: The downlink transmit power exceeds a certain threshold
(90%, in relation to MaxDlDpchPwr of services). The downlink transmit power is
measured by the Node B and reported to the RNC through the dedicated Node B
measurement report.
The UE reports Event 2D.
5.1.2.2 Measurement Modification
If the inter-frequency measurement is enabled, an inter-frequency measurement
modification is triggered in the following cases:
If the inter-frequency measurement parameters and adjacent cells change after a
soft handover, the changed parameters and adjacent cells must be updated through
a measurement modification.
Handover Control Feature Guide
ZTE Confidential Proprietary 80
If the handover parameters change when a service is added or deleted, the
changed parameters must be updated through a measurement modification.
5.1.2.3 Measurement Deletion
When the following inter-frequency measurement setup conditions are no longer met, the
corresponding inter-frequency measurement will be deleted (released).
There is no inter-frequency adjacent cell in the active set after a handover and
inter-frequency measurement is initiated.
There is an inter-frequency adjacent cell but it has ShareCover (Covers) relation
with a cell or an intra-frequency adjacent cell in the current active set, and an
inter-frequency measurement is initiated.
An inter-frequency measurement is initiated but the radio quality of working carrier
frequency becomes better. The standards for judging “The Radio Quality of Working
Carrier Frequency Changes Better” are described as follows:
The UE does not report Event 2D or reports Event 2F.
The uplink BLER does not exceed the poor quality threshold (1.25%) or the BLER
recovers below the normal quality threshold (CS64K: 0.1%; other services: 1%).
The UE‟s transmit power does not exceed inter-frequency measurement initiation
threshold (100%) or recovers below normal value (90%).
The downlink transmit power does not exceed inter-frequency measurement
initiation threshold (90%) or recovers below the normal value (80%).
An inter-frequency handover is completed.
An exception occurs, for example, receiving an exceptional inter-frequency
measurement report (for example, the measurement report belongs to a
non-existent measurement task on the network side).
When the RNC sends a MEASUREMENT CONGROL RELEASE message for a
measurement ID, the time stamp is recorded. If the RNC receives the measurement
Handover Control Feature Guide
ZTE Confidential Proprietary 81
report for the ID, it compares the current time and the recorded time. If the difference
between the current time and the recorded time exceed the threshold TResndMeaCtrlRel
(URncFunction) configured, the MEASUREMENT CONTROL RELEASE will be resent.
Otherwise, this measurement report will be ignored.
5.1.2.4 Processing of Inter-Frequency Events
1. Processing of Event 2A/2B/2C
If a measurement report contains several target cells, those with good quality
(RSCP) are preferentially selected as target cells. If there is any inter-frequency
adjacent cell that has ShareCover (Overlap or Covers) relation with the target cell,
inter-frequency load balancing is performed based on the cell‟s load. (For details,
see ZTE UMTS Load Balance Feature Guide).
For CS users, an inter-frequency hard handover is performed.
For PS users, a hard handover tends to fail due to admission failure in the event of
heavy cell load because a majority of resources are occupied by PS services. The
following strategies are required:
If the current channel type is DCH and the channel assigned for the target cell
is also DCH after a handover, a handover attempt is made first according to
the current rate. If the handover fails, another handover attempt is made
according to the GBR of the current services or the minimum rate grade of
DRBC (for details, see ZTE UMTS DRBC Algorithm Feature Guide), to
improve the handover success rate.
If the current channel type is HS-DSCH/E-DCH or HS-DSCH/DCH, and DCH
after a handover, the handover is performed directly according to the GBR of
the current services or the minimum rate grade of DRBC (for details, see ZTE
UMTS DRBC Algorithm Feature Description).
If the channel type is DCH before a handover and HS-DSCH/E-DCH or
HS-DSCH/DCH after it, the handover is admitted by the HS-DSCH/E-DCH or
HS-DSCH/DCH (for details, see ZTE UMTS DRBC Algorithm Feature Guide).
If the HS-DSCH/E-DCH or HS-DSCH/DCH admission fails, the handover can
Handover Control Feature Guide
ZTE Confidential Proprietary 82
also be implemented according to the minimum rate (GBR of services or
minimum rate grade of DRBC) of DCH.
In a cell, only one of Event 2A, Event 2B and Event 2C can be used to trigger an
inter-frequency handover. Which event is used depends on the inter-frequency
handover recommendation strategy parameter InterHoTactic (UUtranCellFDD).
If an inter-frequency handover fails, the penalty timer GresPara6, which is specific
to the UE, is started. The RNC will not process the reported inter-frequency
measurement reports before the timer expires, and will issue a new inter-frequency
measurement control message after the timer expires.
2. Processing of Event 2D
A blind handover attempt is made if there is a ShareCover (UUtranRelation) (2:
Covers) relationship in the inter-frequency adjacent cells.
Compressed mode is initiated and an inter-frequency measurement 2A/2B/2C/2E is
issued if there is no ShareCover (UUtranRelation) (Covers) relation in
inter-frequency adjacent cells or a blind handover fails. For the initiation decision of
compressed mode, see “Compressed Mode Enabling/Disabling”.
3. Processing of Event 2E
All non-working carrier frequencies report Event 2E, indicating that the radio quality
of all inter-frequency adjacent cells is poor and the 3G system quality deteriorates. If
there is any Inter-RAT adjacent cell that has cover relation (GsmShareCover
(UGsmRelation) value is “2 GSM neighboring cell covers the serving cell”) with the
current serving cell, an inter-RAT blind handover is implemented.
All non-working carrier frequencies report Event 2E, indicating that the radio quality
of all inter-frequency adjacent cells is poor and the 3G system quality deteriorates. If
the serving cell does not have any inter-RAT neighboring cell with cover relation
(GsmShareCover (UGsmRelation) value is not “2 GSM neighboring cell covers the
serving cell”), an inter-RAT measurement Event 3A/3C is issued.

For details, see Compressed Mode Enabling/Disabling and “Inter-Frequency
Measurement Control Method Measurement Deletion”.
5.1.2.5 Minimum Quality Judgement Strategy in Inter-frequency Handover
For 2A, 2B, 2C events:
1. CresPara6 (UCelInfoFDD) is set to “1: On”.
2. The UE reports Event 2A/2B/2C.
3. The quality of the target cell: CPICH EcNo<=GresPara2 (URncFunction) or CPICH
RSCP<=GresPara5 (URncFunction).
If these conditions are met, the RNC will not process Event 2A/2B/2C reported by the
UE.
5.1.2.6 Processing of Inter-Frequency and Inter-RAT Events in Buffer
If the RNC receives a measurement report and does not process it, the RNC may miss
handover opportunities and even drop the call when the RNC processing other events
such as the radio bearer reconfiguration procedure. So, the RNC needs to buffer these
events and does not process them until the current event has been processed.
There are six inter-frequency measurement events and six inter-RAT measurement
events in the buffer at most.
For event 2D/2F, if the measurement quantity (NonIntraMeasQuan
(UUtranCellFDD)) is “CPICH EcNo” or “CPICH RSCP”, the RNC will only buffer the
measurement events with the same measurement quality defined by
NonIntraMeasQuan (UUtranCellFDD). If the measurement quantity
(NonIntraMeasQuan (UUtranCellFDD)) is “CPICH EcNo and CPICH RSCP”, the
RNC will buffer the latest events with CPICH EcNo and CPICH RSCP measurement
quantity individually.
Handover Control Feature Guide
ZTE Confidential Proprietary 84
If Event 2A/2B/2C/2E or 3A/3C measurement event exists in the buffer and the
newly reported Event 2F has the same measurement quantity as
NonIntraMeasQuan (UUtranCellFDD), the RNC will delete the 2A/2B/2C/2E or
3A/3C and buffer Event 2F. Otherwise, the RNC will not process Event 2F.
If Event 2F with the same measurement quantity defined by NonIntraMeasQuan
(UUtranCellFDD) exists in the buffer, when Event 2A/2B/2C/2E or 3A/3C is reported,
the RNC will not process Event 2A/2B/2C/2E or 3A/3C. Otherwise, the RNC will
buffer these events.
After an intra-frequency and Intra-frequency hard handover, the RNC needs to
discard all measurement events in the buffer.
5.1.2.7 Parameter Configuration Strategies
Inter-frequency event parameter configuration
There are six inter-frequency measurement events (2a, 2B, 2C, 2D, 2E, and 2F) in
total. The number of events configured depends on the parameter MeasEvtNum (If
the measurement is an event-triggered measurement and the measurement
quantity is EcNo, for Event 2D/2F used for the EUTRAN system, this parameter is
obtained from UInterEcNoEvMeasforE. For Event 2D/2F used for the GSM system,
this parameter is obtained from UInterEcNoEvMeasforG. For inter-frequency
measurement events used for the UTRAN system, this parameter is obtained from
UInterEcNoEvMeasforU. If the measurement is an event-triggered measurement
and the measurement quantity is RSCP, for Event 2D/2F used for the EUTRAN
system, this parameter is obtained from UInterRscpEvMeasforE. For Event 2D/2F
used for the GSM system, this parameter is obtained from UInterRscpEvMeasforG.
For inter-frequency measurement events used for the UTRAN system, this
parameter is obtained from UInterRscpEvMeasforU), and the inter-frequency
events configured depends on the parameter meaEvtId (If the measurement is an
event-triggered measurement and the measurement quantity is EcNo, for Event
2D/2F used for the EUTRAN system, this parameter is obtained from
UInterEcNoEvMeasforE. For Event 2D/2F used for the GSM system, this parameter
is obtained from UInterEcNoEvMeasforG. For inter-frequency measurement events
used for the UTRAN system, this parameter is obtained from
Handover Control Feature Guide
ZTE Confidential Proprietary 85
UInterEcNoEvMeasforU. If the measurement is an event-triggered measurement
and the measurement quantity is RSCP, for Event 2D/2F used for the EUTRAN
system, this parameter is obtained from UInterRscpEvMeasforE. For Event 2D/2F
used for the GSM system, this parameter is obtained from UInterRscpEvMeasforG.
For inter-frequency measurement events used for the UTRAN system, this
parameter is obtained from UInterRscpEvMeasforU). meaEvtId is defined through
array, and the dimension of array is equal to MeasEvtNum, which is six at most.
Handover parameter configuration strategy in macro diversity
All measurement parameters are cell-based. In macro diversity, the measurement
parameters configured in the best cell will be used as handover parameters. If the
best cell changes, the measurement parameters need to be updated at the same
time.
For inter-RNC handover, if there is an SRNC cell in the active set, the measurement
parameters of the best cell in the SRNC will be used as handover parameters, and if
there is no SRNC cell in the active set, the measurement parameters of the last
SRNC cell in the active set will be used as handover parameters.
Configuration of several sets of handover parameters
The inter-frequency handover parameters can be separately configured based on
measurement quantity, measurement reporting mode and service bearer type. In
this way, several sets of measurement parameters are necessary for different
purposes. The specific categories are described as follows:
Measurement quantity
NonIntraMeasQuan (UUtranCellFDD) (CPICH RSCP or EcNo or both)
Note:
When NonIntraMeasQuan (UUtranCellFDD) is configured to “EcNo” or “RSCP”,
only the 2D/2F events corresponding measurement quality are issued.
When NonIntraMeasQuan (UUtranCellFDD) is configured to “EcNo and RSCP”,
two categories of 2D/2F measurement events about CPICH EcNo and CPICH
Handover Control Feature Guide
ZTE Confidential Proprietary 86
RSCP are configured and one of 2D measurement events can trigger compressed
mode. After compressed mode is triggered, the inter-frequency event of the
corresponding measurement quantity will be issued according to that of 2D event.
For example, if the measurement quantity of triggering 2D event is CPICH EcNo,
only an inter-frequency event of CPICH EcNo will be issued.

Note: When a new cell is set up, the value of intialHoCelSelScene (UInterMeasProfile)
(0:Outdoor Scene, 1:High-Mobility Outdoor Scene, 2:Indoor Scene, 3:Subway/tunnel
Scene) is determined according to the actual cell scene (indicated by HoCelSelScene
(UUtranCellFDD)), and the available inter-frequency measurement profile corresponding
to intialHoCelSelScene is configured for the cell.
Before inter-frequency handover parameters are obtained, profileId
(UInterMeasProfile) of the cell is found based on refUinterMeasProfile
(UUtranCellFDD), and then, in UinterMeasProfile configuration items, the next level
managed object is obtained according to the current measurement application type:
For event-triggered measurements, “Inter-frequency Measurement Configuration
Related to Traffic Category Object ID(UInterMeaSrvSpec)” is selected. For
periodical measurements, “Inter-frequency Measurement Configuration Unrelated to
Traffic Category Object ID (UInterMeasNoSrvSpec)” is selected.
Handover Control Feature Guide
ZTE Confidential Proprietary 88
In the managed object decided above, “Inter-Frequency Measurement
Configuration No. (InterMeasCfgNo)” is found based on “Traffic
Category(srvCategory(UInterMeaSrvSpec))” and “Measurement
Quantity(NonintraMeasQuan)”. Finally, the corresponding inter-frequency handover
measurement parameters are found. The details are as follows:
(1). Event-triggered measurement
i. Inter-frequency measurement events used for the UTRAN system
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UInterEcNoEvMeasforU.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UInterRscpEvMeasforU.
ii. Event 2D/2F used for the GSM system
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UInterEcNoEvMeasforG.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UInterRscpEvMeasforG.
iii. Event 2D/2F used for the EUTRAN system
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UInterEcNoEvMeasforE.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UInterRscpEvMeasforE.
(2). Periodical measurement
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object UInterEcNoPrdMeas.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object UInterRscpPrdMeas.
Handover Control Feature Guide
ZTE Confidential Proprietary 89
Correspondence between other parameters that need to be filled into the
inter-frequency measurement control message
Inter-Frequency measurement quantity and Inter-frequency measurement report
criteria are automatically filled by the system based on InterMeasCfgNote.
For the cells of the neighbor RNC, if the value of Primary CPICH Power
Configuration Tag (PcpichPwrPre (UExternalUtranCellFDD)) is TURE, the cell
information of the inter-freq measurement should include the Primary CPICH Power
for this cell. Otherwise the cell information of the inter-freq measurement should not
include the Primary CPICH Power for this cell.
Switch of inter-frequency handover based on measurement for different services
There are several switches for different services to control whether
measurement-based inter-frequency handovers can be performed. When such a
switch is open, it is allowed to perform inter-frequency handovers for the
corresponding service. Otherwise, the RNC forbids inter-frequency handovers for
the service by not activating the inter-frequency measurement. The switches for
different services are described as followed:
Service Switch
AMR amrIfHoSw (ULogicalRnc)
R99 RT r99RtIfHoSw (ULogicalRnc)
R99 NRT r99NrtIfHoSw (ULogicalRnc)
HSDPA hsdpaIfHoSw (ULogicalRnc)
HSUPA hsupaIfHoSw (ULogicalRnc)
Strategy of coupling between intelligent carrier power off/on and inter-frequency
handover
When the intelligent carrier power control is enabled, and the cell meets the
conditions of carrier power off, compressed mode must be initiated for
inter-frequency/inter-RAT measurements, no matter what IfOrRatHoSwch
(UCelInfoFDD) or
amrIfHoSw/r99RtIfHoSw/r99NrtIfHoSw/hsdpaIfHoSw/hsupaIfHoSw (ULogicalRnc)
is.
Handover Control Feature Guide
ZTE Confidential Proprietary 90
5.1.3 Neighboring Cells Configuration
During the neighboring cells configuration, the adjacent cell list used for reselection in
non-CELL_DCH state and that used for handovers in CELL_DCH state can be
configured separately. During handovers, target cells are selected by neighboring cells
configuration state (StateMode (UUtranRelation)). When the UE is in macro diversity
state, the neighboring cell list is a combination of neighboring cell lists of each cell in the
active set, so the number of inter-frequency neighboring cells may exceed 32, which is
the maximum number specified by the protocol. If the number of inter-frequency
neighboring cells exceeds 32, some cells must be deleted to ensure that there are only
32 inter-frequency neighboring cells. With minimal impact on the UEs in the active set,
these dropped cells are those with poorer signal quality or remoter geographical location.
Therefore, each inter-frequency neighboring cell is configured with a priority.
5.1.3.1 Cell priority configuration
The OMCR configuration parameter MeasPrio (UUtranRelation) defines the priority of
adjacent cells with three values (0: High priority; 1: Medium priority; 2: Low priority). The
value of MeasPrio (UUtranRelation) must be set by the network planning engineer based
on the existing network conditions (for example, adjacent cell quality and geographical
location of adjacent cell). 0 shows the cell priority configuration based on the
geographical location of adjacent cells. For example, for the configuration of cells
adjacent to the innermost gray cell, there are three layers of adjacent cells surrounding
the gray cell, and they are differentiated from one another with yellow (0: Top priority),
blue (1: Medium priority) and red (2: Low priority).

5.1.3.2 Strategy for Adjacent Cells Exceeding 32
As specified in the protocol, the maximum number of inter-frequency adjacent cells is 32.
When the UE is in macro diversity state, the total number of inter-frequency adjacent
cells in the macro diversity may exceed 32, so some strategies are required to control the
number within 32, including:
Priority combination strategy
If a cell is adjacent to several inter-frequency cells in the active set, that is, the priority
levels configured for this cell may vary, the priority levels of this cell are combined and
the highest priority level prevails.
Sorting strategy
If the total number of inter-frequency adjacent cells in the active set is 32, the system
prioritizes them in descending order and places the cells in excess of 32 into the
inter-frequency adjacent cell reserve list, which can buffer at most 8 truncated
inter-frequency cells.
The priority levels of adjacent cells in the inter-frequency adjacent cell list will be updated
whenever Event 1A/1B/1C/1D is triggered. If Event 1B is triggered and the number of
Handover Control Feature Guide
ZTE Confidential Proprietary 92
inter-frequency adjacent cells is less than 32, the system selects cells from the reserve
list in descending order of priority and places them into the inter-frequency adjacent cell
list. The number of cells that can be selected: min (32 – Number of existing cells in the
inter-frequency adjacent cell list, Number of cells in the reserve list).
5.2 Handling Mechanism for Periodical Report of
Inter-Frequency and Inter-RAT Handover
Measurement
The periodical reporting is that a report of inter-frequency/inter-RAT measurement result
is sent by the UE periodically based on the periodical report interval (PrdRptInterval (For
an inter-frequency measurement, if the measurement quantity is EcNo, this parameter is
obtained from UInterEcNoPrdMeas. If the measurement quantity is RSCP, this
parameter is obtained from UinterRscpPrdMeas. For an inter-RAT measurement, if the
measurement quantity is EcNo, this parameter is obtained from URatEcNoPrdMeas. If
the measurement quantity is RSCP, this parameter is obtained from URatRscpPrdMeas))
and the amount of periodical reports (PrdRptAmount (For an inter-frequency measurement,
if the measurement quantity is EcNo, this parameter is obtained from
UInterEcNoPrdMeas. If the measurement quantity is RSCP, this parameter is obtained
from UInterRscpPrdMeas. For an inter-RAT measurement, if the measurement quantity
is EcNo, this parameter is obtained from URatEcNoPrdMeas. If the measurement
quantity is RSCP, this parameter is obtained from URatRscpPrdMeas)) configured by
RNC. The RNC judges inter-frequency/inter-RAT handover events in accordance with
the inter-frequency/inter-RAT event rule defined in the protocol by referring to the
inter-frequency/inter-RAT cell quality periodically reported by the UE. (For details on the
period algorithm, see “5.11 Inter-frequency and Inter-RAT Period Measurement
Algorithm”)
A long interval set in periodical reporting mode may result in call drop due to handover
delay. Therefore, it is recommended to set the interval to a low value. However, setting a
short interval will increase the signaling load of radio interface and easily lead to
signaling congestion, so event-triggered reporting is generally preferred.

5.3 Downlink Coverage Based Inter-Frequency
Handover
Downlink coverage uses Events 2D and 2F as a criterion to evaluate the quality of
current working carrier frequency signals. For details on processing strategies of Events
2D and 2F, see “Processing of Inter-Frequency Events”.
A coupling relationship exists among the coverage-based handover, uplink BLER-based
handover, uplink transmit power-based handover, downlink transmit power-based
handover, and moving speed-based handover. For details on enabling/disabling of
compressed mode and inter-frequency measurement setup/release, see
“Inter-Frequency Handover Strategy--> Coupling Processing of Different Handovers”.
5.4 Uplink BLER Based Inter-Frequency Handover
The activation of uplink BLER-based inter-frequency handovers is controlled through the
parameters RncUlBlerHoSwch and UlBlerHoSwch (UUtranCellFDD).
This strategy only applies to the DCH.
When the values of RncUlBlerHoSwch and UlBlerHoSwch (UUtranCellFDD) are both
“ON”, the RNC periodically collects the statistics of uplink BLER. If the uplink BLER value
exceeds a certain threshold (1.25%) and the Sirtarget value (real-time measurement
result) reaches the maximum value of SIR (ULMaxSIR) configured in the OMCR, then
the outer loop power control is already invalid and the uplink quality worsens. In such a
case, the UE is handed over into its inter-frequency adjacent cell that has ShareCover
(Covers) relation with the current cell, or an inter-frequency measurement is initiated.
The processing strategy is the same as that of Event 2D. For details, see Event 2D
processing in “Processing of Inter-Frequency Events”.
Handover Control Feature Guide
ZTE Confidential Proprietary 94
5.5 Uplink Transmit Power Based Inter-Frequency
Handover
The activation of uplink transmit power-based inter-frequency handovers is controlled
through the parameters RncTxPwrHoSwch and UlPwrHoSwch (UUtranCellFDD).
This strategy only applies to the DCH.
When the values of RncTxPwrHoSwch and UlPwrHoSwch(UUtranCellFDD) are both
“ON”, the RNC sets up the internal measurement of UEs when a service is initially
established. The UE internal measurement mainly measures the UE transmission power
(TxP) by event report.
Before obtaining the UE‟s internal measurement parameters, the profileId
(UUeIntMeasProfile) of the cell is found based on refUUeIntMeasProfile(UUtranCellFDD).
Then, according to the current measurement purpose “UE Transmitted Power Event
Measurement for Handover”, the managed object UHoEvtTPUeInt is obtained from
UUeIntMeasProfile configuration items. Finally, “UE Internal Measurement Configuration
Index (UeIntMCfgNo (UHoEvtTPUeInt))” and the following corresponding internal
measurement parameters are obtained from UHoEvtTPUeInt.
Measurement Report Transfer Mode measRptTrMod(UHoEvtTPUeInt)
Filter Coefficient filterCoeff(UHoEvtTPUeInt)
Maximum Event Number of UE Internal Measurement measEvtNum(UHoEvtTPUeInt)
UE Internal Measurement Event Identity meaEvtId(UHoEvtTPUeInt)
Time to Trigger(ms) trigTime(UHoEvtTPUeInt)
When the transmit power of the UE meets these threshold requirements, the UE will
report the corresponding events. After receiving an Event 6A report (The uplink power of
the UE exceeds txPowerThres(UHoEvtTPUeInt)) or an Event 6B report (The uplink
power of the UE is less than txPowerThres(UHoEvtTPUeInt)), the RNC uses the same
processing strategy as that of 2D or 2F, respectively. For details, see the Events 2D and
2F processing strategies in “Processing of Inter-Frequency Events”.
Handover Control Feature Guide
ZTE Confidential Proprietary 95
5.6 Downlink Transmit Power Based Inter-Frequency
Handover
The activation of downlink transmit power-based inter-frequency handovers is controlled
through the parameters RncTxPwrHoSwch and DlPwrHoSwch (UUtranCellFDD).
This strategy only applies to the DCH.
The Node B periodically sends the dedicated measurement report of downlink transmit
power to the RNC.
When the values of RncTxPwrHoSwch and DlPwrHoSwch (UUtranCellFDD) are both
“On”, the RNC will judge the downlink code power (DTCP) mentioned in the dedicated
measurement report sent by the Node B.
Obtaining of the Node B dedicated measurement parameters: According to the current
measurement purpose “Event A Report Parameters for TCP in Handover Control”/”
Event B Report Parameters for TCP in Handover Control”, the following parameters used
for handover control are obtained from the sub-object UNbDedMeas of the object
UNbDedMeasProfile:
Dedicated Measurement Type DedMeasType (UNbDedMeas)
Measurement Change Time /Measurement Hysteresis
Time EvtAbcdefTime (UNbDedMeas)
Measurement Filter Coefficient MeasFilterCoeff (UNbDedMeas)
Report Period RptPrd(UNbDedMeas)
Choice Report Periodicity Scale RptPrdUnit (UNbDedMeas)
Report Characteristics RptType(UNbDedMeas)
Measurement Threshold of Event A/B for Transmitted
Code Power EvtAbTcpThrd(UNbDedMeas)
NbDed Measure Configuration No NbDMCfgNo(UNbDedMeas)
When the DTCP value reaches the threshold of Event A, it indicates that the downlink
power is very high. In such a case, the UE is handed over to its inter-frequency adjacent
Handover Control Feature Guide
ZTE Confidential Proprietary 96
cell that has ShareCover (Covers) relation with the current cell, or an inter-frequency
measurement is initiated. The processing strategy is the same as that of Event 2D. When
the DTCP value reaches the threshold of Event B, the processing strategy is the same as
that of Event 2F. For details, see Event 2D/2F processing in “Processing of
Inter-Frequency Events”
5.7 Load Control Based Handover
When the load (downlink carrier power (TCP) or total uplink receive wideband power
(RTWP)) of a cell reaches a high level, if the cell has some less-loaded inter-frequency
adjacent cells that have ShareCover (Overlap or Covers) relation with this cell (judged
through ShareCover(UUtranRelation)), the RNC will hand over some UEs with low
priority from this cell into its adjacent cells to reduce this cell‟s load and ensure system
stability.
For details on load handover, see ZTE UMTS Overload Control Feature Guide.
5.8 Moving Speed Based Handover
In the Hierarchical Cell Structure (HCS), Macro cells are used to carry the fast-moving
UEs and they have low HCS priority (HcsPrio (for the current cell, this parameter is
obtained from UUtranCellFDD. For neighboring UTRAN cells, this parameter is obtained
from UExternalUtranCellFDD. For neighboring GSM cells, this parameter is obtained
from UExternalGsmCell)). Micro cells are used to carry the slow-moving UEs and they
have high HCS priority (HcsPrio).
The purpose of moving speed-based handovers is to hand over the fast-moving and
slow-moving UEs into Macro and Micro cells, respectively. The handover between Macro
and Micro cells requires an algorithm for judging the moving speeds of UEs. Whether to
process the handover judgement based on moving speed depends on the parameter
HcsSupportInd(URncFunction).
The number of best cell changes per unit time is taken as a criterion for judging the
moving speed of UEs. The more times the best cell changes per unit time, the faster the
moving speed. The number of best cell changes is based on the number of Event 1D
Handover Control Feature Guide

reports.
5.9 Coupling Processing of Different Handovers
Inter-frequency handover can be triggered by the following:
Load control
Downlink coverage events
Uplink transmit power
Uplink BLER
Downlink transmit power
Moving speed of UE
The load control-based handover aims to quickly reduce system loads and ensure
system stability, and it has the top priority. The handovers based on downlink coverage
events, uplink transmit power, uplink BLER or downlink transmit power aim to guarantee
the call QoS and user experience, and they have lower priority. The moving speed-based
handover in the HSC is used to appropriately allocate traffic for different cells, make full
use of system resources and enhance system performance. The moving speed-based
handover is a system optimization function and has the lowest priority.
The handover with top priority will shield the handovers with comparatively lower priority.
For example, if a load control-based handover occurs in a cell, the RNC can no longer
hand over or access new services into the cell. In the case of a poor carrier quality, the
RNC needs to hand over the UE into the cell with good quality through radio quality
measurement, without taking account of the moving speed of UE.

5.10 Inter-frequency and Inter-RAT Measurement Choice
When a cell has both neighboring inter-frequency and neighboring inter-RAT cells,
IfOrRatHoSwch (UCelInfoFDD) is used to indicate the priority of inter-frequency and
inter-RAT handovers.
IfOrRatHoSwch indicates “Turn off Inter-frequency and Inter-RAT Handover”.
Neither inter-frequency measurement nor inter-RAT measurement will be issued by
the RNC.
IfOrRatHoSwch indicates “Only Inter Frequency”.
If inter-frequency neighboring cells exist, the parameters of
inter-frequency 2D/2F event are initially issued (If the measurement
quantity is EcNo, the parameters are obtained from
UInterEcNoEvMeasforU. If the measurement quantity is RSCP, the
parameters are obtained from UInterRscpEvMeasforU). When
compressed mode is activated, only inter-frequency measurements are
issued by the RNC.
If no inter-frequency neighboring cell exists, no inter-frequency
measurement is issued by the RNC.
IfOrRatHoSwch indicates “Only Inter RAT”.
If both GSM and EUTRAN neighboring cells exist, according to
ChoStraMulRatHo(UCelInfoFDD), the parameters of inter-RAT 2D/2F
events are initially issued (If the measurement quantity is EcNo, the
parameters of EUTRAN inter-RAT 2D/2F events are obtained from
UInterEcNoEvMeasforE, and the parameters of GSM inter-RAT 2D/2F
events are obtained from UInterEcNoEvMeasforG. If the measurement
quantity is RSCP, the parameters of EUTRAN inter-RAT 2D/2F events
are obtained from UInterRscpEvMeasforE, and the parameters of GSM
inter-RAT 2D/2F events are obtained from UInterRscpEvMeasforG).
When compressed mode is activated, only RATx measurements
according to ChoStraMulRatHo are issued by the RNC.
Handover Control Feature Guide
ZTE Confidential Proprietary 99
If only GSM or EUTRAN neighboring cells exist, the parameters of GSM
inter-RAT 2D/2F events or EUTRAN inter-RAT 2D/2F events are initially
issued. When compressed mode is activated, only GSM or EUTRAN
measurements are issued by RNC.
If no inter-RAT neighboring cell exists, no inter-RAT measurement will be
issued by the RNC.
IfOrRatHoSwch indicates “Inter Frequency Is Prior to Inter RAT”.
If Only inter-frequency neighboring cells exist, the parameters of
inter-frequency 2D/2F events are initially issued. When compressed
mode is activated, inter-frequency measurements are issued by the RNC.
If only both GSM and EUTRAN neighboring cells exist, the parameters of
inter-RAT 2D/2F events are initially issued. When compressed mode is
activated, only RATx measurements according to ChoStraMulRatHo
(UCelInfoFDD) are issued by the RNC.
If only GSM or EUTRAN neighboring cells exist, the parameters of GSM
inter-RAT 2D/2F events or EUTRAN inter-RAT 2D/2F events are initially
issued. When compressed mode is activated, GSM or EUTRAN
measurements are issued by the RNC.
If both inter-frequency and inter-RAT neighboring cells exist, the RNC will
initially issue the parameters of inter-frequency 2D/2F events, and then
configure the inter-frequency measurement first when compressed mode
is activated and start the timer T4StpIfMeaActRat (URncFunction), when
a 2E event is reported or T4StpIfMeaActRat (URncFunction) expires, the
RNC will reconfigure the inter-frequency measurement to inter-RAT
measurement.

Algorithm
Inter-frequency and inter-RAT measurement can use event-triggered reporting method
or periodical reporting method, which is controlled by the RNC level parameters
InterHoMth and IntRatHoMth. When InterHoMth and IntRatHoMth are both “1: Event
Method”, the handover strategy corresponding to the event-triggered measurement is
used (For details, see “5.1.2.4 Processing of Inter-Frequency Events” and “5.10
Inter-frequency and Inter-RAT Measurement Choice”). Otherwise, the inter-frequency
and inter-RAT period measurement algorithm described below is used.
5.11.1 Period Measurement Configuration
InterHoMth is “0: Periodical Method”, IntRatHoMth is “1: Event Method”
The RNC issues period measurement configuration for inter-frequency measurement,
and event measurement configuration for inter-RAT measurement. Inter-frequency and
inter-RAT compressed modes are still activated separately. (For details about issuing
inter-frequency measurements or inter-RAT measurements, see “5.10 Inter-frequency
and Inter-RAT Measurement Choice”)
InterHoMth is “1: Event Method”, IntRatHoMth is “0: Periodical Method”
The RNC issues event measurement configuration for inter-frequency measurement,
and period measurement configuration for inter-RAT measurement. Inter-frequency and
inter-RAT compressed modes are still activated separately. (For details about issuing
inter-frequency measurements or inter-RAT measurements, see “5.10 Inter-frequency
and Inter-RAT Measurement Choice”)
InterHoMth is “0: Periodical Method”, IntRatHoMth is “0: Periodical Method”
IfOrRatHoSwch is “Only Inter Frequency” or “Only Inter RAT”
The RNC issues period measurement configuration for both inter-frequency and
inter-RAT measurements. (For details about issuing inter-frequency measurements or
Handover Control Feature Guide
ZTE Confidential Proprietary 101
inter-RAT measurements, see “5.10 Inter-frequency and Inter-RAT Measurement
Choice”)
IfOrRatHoSwch is “Inter Frequency Is Prior to Inter RAT”
Inter-frequency handover and inter-RAT handover are allowed.
a) When compressed mode is initiated by Event 2D, BLER or uplink/downlink transmit
power, the RNC issues inter-frequency and inter-RAT period measurement
configurations and activates the corresponding compressed modes simultaneously.
b) When compressed mode is initiated by measurement-based balancing or moving
speed-based inter-frequency handover, if the current frequency quality is good, only
inter-frequency period measurement configuration is issued and the corresponding
compressed mode is activated. Otherwise, the same strategy described in a) is
performed.
c) When compressed mode is initiated by the value of service handover IE, if the
current frequency quality is good, only inter-RAT period measurement configuration
is issued and the corresponding compressed mode is activated. Otherwise, the
same strategy described in a) is performed.
Note:
1) When the period measurement algorithm is used, Event 2D/2F is still reported by
using the event-triggered method.
2) When the measurement quantity is CPICH EcNo+RSCP, the period measurement
configuration corresponding to CPICH RSCP is selected.
3) When IntRatHoMth is “0: Periodical Method”, only two sets of compressed modes
(GSM carrier RSSI Measurement, GSM Initial BSIC Identification) are configured for
GSM; and inter-frequency and inter-RAT compressed modes are configured
simultaneously regardless of CompMdCfgStra.

5.11.2 Processing of Period Measurement Report
For one neighbor cell‟s period measurement report reported by the UE, the RNC will
judge it in accordance with the inter-frequency/inter-RAT event rule. If an event (M) is
met, the cell-specific timer PeriodTriggerTime (UCelInfoFDD) is initiated and Event M is
recorded. Event M will be exported as the final event, if the neighboring cell‟s periodical
measurement reports keep meeting Event M until the timer expires. Follow-up handovers
are still processed based on the existing handover strategy for event-triggered reporting.
Judgment criterion of periodical measurement report
(1). For inter-frequency measurements, the target cell is judged according to the Event
2C triggering rule.
QTarget_Freq_Cell+ CIOTarget_Freq_Cell>= TTarget_Freq_Cell+H/2
Where:
QTarget_Freq_Cell: Refers to the quality of the target carrier frequency.
CIOTarget_Freq_Cell: Refers to the cell individual offset of the target carrier frequency

TTarget_Freq_Cell: Refers to the absolute threshold (ThreshNoUsedFreq (If the measurement
quantity is EcNo, this parameter is obtained from UInterEcNoEvMeasforU. If the

decision.
H: Refers to the handover decision hysteresis parameter (Hysteresis (If the
measurement quantity is EcNo, this parameter is obtained from UInterEcNoEvMeasforU.

5.12 Inter-Frequency Handover Procedure
Inter-frequency handovers are all hard handovers, and their procedures are identical with
intra-frequency hard handovers.
Handover Control Feature Guide
ZTE Confidential Proprietary 104
6 Inter-RNC Mobility
6.1 SRNS Relocation
SRNS relocation can be categorized into relocation of UE not involved (soft
handover-triggering) and relocation of UE involved (hard handover-triggering),
depending on UE relevance.
Relocation of UE not involved
It belongs to the soft handover relocation, and the UE can use radio resources in the
DRNC and connect with the CN through the SRNC. The triggering conditions are
described as follows:
There is an Iur interface between RNCs.
The switch of relocation of UE not involved is open. It is differentiated by CS
service and PS service, RncFeatSwitchBit10 is for CS service and
RncFeatSwitchBit11 for PS service.
When all radio links are handed over to the DRNC, the timer
(CsReDelayTimer(UIurLink) is activated and PsReDelayTImer(UIurLink) are
configured according to CS service and PS service respectively, the timer of
CS service is considered for the multi-RAB service) and a relocation is
performed when the corresponding timer expires.
Relocation of UE involved
It belongs to the hard handover relocation. The triggering conditions are described as
follows:
For CS services, the switch of relocation RncFeatSwitchBit0 is open.
For PS services, the switch of relocation RncFeatSwitchBit19 is open.
For CS and PS combined services, the switch of relocation RncFeatSwitchBit0
is open.
Handover Control Feature Guide
ZTE Confidential Proprietary 105
Special relocation processing of CS+PS services
If the UE has CS and PS services simultaneously and the DRNC of network vendor does
not support PS relocation, the PS services will be released before an SRNC relocation
with hard handover is performed when the parameter RncFeatSwitchBit4 is set to “1”.
The CS service will begin relocation as soon as the PS service is released. As a result,
the CS service will be kept, but the PS service will be reestablished by the UE
automatically.

Procedure description:
1. Upon detecting that all links already exist in a DRNC, the SRNC initiates the
relocation procedure and sends a “Relocation Required” message to the CN. If the
SRNC connects with CS and PS domains, it needs to send the “Relocation
Required” message to the CS and PS domains. When the SRNC sends the
Relocation Required message, it starts the timer Trelocprep(UIuCnst). Upon
receiving the Relocation Command message, the SRNC stops the timer and
terminates the Relocation Preparation procedure. If there is no response from the
Handover Control Feature Guide
ZTE Confidential Proprietary 106
CN to the Relocation Required message before the timer Trelocprep(UIuCnst)
expires, the SRNC cancels the Relocation Preparation procedure by initiating the
Relocation Cancel procedure with the cause “Trelocprep expiry”.
2. The CN sends a “Relocation Request” message to the DRNC, carrying the “RAB
SETUP” IE.
3. After the RAB of DRNC is established successfully, the DRNC sends a “Relocation
Request Ack” message to the CN.
4. The CN sends a “Relocation Command” message to the SRNC, requiring the
SRNC to start a relocation. Upon receiving the Relocation Command message, the
SRNC stops the timer Trelocprep(UIuCnst), starts the timer Trelocoverall(UIuCnst)
and terminates the Relocation Preparation procedure. If the Iu Release procedure is
not initiated towards the SRNC from the CN before the expiry of
Trelocoverall(UIuCnst), the SRNC initiates the Iu Release Request procedure
towards the CN with cause “Trelocoverall expiry”.
5. The SRNC sends a “Relocation Commit” message to the DRNC through the lur
interface.
6. The DRNC sends a “Relocation Detect” message to the CN and is converted into a
new SRNC through role exchange.
7. The new SRNC sends a “UTRAN Mobility Information” message to the UE to
reallocate U-RNTI.
8. Upon relocating U-RNTI, the UE sends a “UTRAN Mobility Information Confirm”
message to the new SRNC.
9. The new SRNC sends a “Relocation Complete” message to inform the CN of the
successful relocation.
10. Upon receiving the message from the new SRNC, the CN sends an “Iu Release
Command” message to the original SRNC to release all the resources in the original
SRNC.
Handover Control Feature Guide
ZTE Confidential Proprietary 107
11. Upon releasing the lu resource, the original SRNC sends an “Iu Release Complete”
message to the CN.
There may be some exceptional procedures during a relocation.
Relocation failure caused by “UTRAN Mobility Information” message transmission
failure
The DRNC fails to initiate the “UTRAN Mobility Information Configuration” procedure
because the procedure times out or the UE fails to return a UTRAN mobility
message. In such a case, the DRNC does not send a “Relocation Complete”
message to the CN, but sends an “Iu Release Request” message to the CN to
release the resources on the DRNC side.
Where “procedure timeout” means: DRNC initiates the timer (400ms) after sending
“UTRAN Mobility Information” (UMI) message to UE, but cannot receive the UMI
confirm message from UE until the timer expires, then DRNC will resend the UMI
message, repeat the process. When the DRNC sends the UMI message for the
fourth time, and the UMI confirm message is not received when the timer expires,
this case is regarded as “procedure timeout”.
Note:
The sent timing of Relocation Detect can be controlled by the parameter
GResPara48(bit11). When GResPara48(bit11) is set to 0, the DRNC will send
Relocation Detect until UTRAN Mobility Information Confirm is received from the UE.
This is different from the above procedures.
Whether to initialize the RNC data forwarding function during a relocation can be
controlled by the parameter RncFeatSwitchBit25 (UIurLink). When
RncFeatSwitchBit25 (UIurLink) is “On”, the RNC will enable this function to
decrease or avoid the data loss in the process of sending UMI.

is no response from the CN to the Relocation Required message before the timer
Trelocprep(UIuCnst) expires, the SRNC cancels the Relocation Preparation
procedure by initiating the Relocation Cancel procedure with the Cause “Trelocprep

6.2 DSCR
6.2.1 R99 DSCR
Like relocation, R99 DSCR is categorized into hard handover DSCR and soft handover
DSCR. The triggering conditions of R99 DSCR are described as follows.
Soft handover DSCR
It means that all radio links are handed over to the DRNC and the relocation is not
performed. The DSCR will be triggered when all the following conditions are met:
The switch of soft handover DSCR RncFeatSwitchBit7 is open.
All radio links are on the DRNC side.
No CS service is included.
Hard handover DSCR
The DSCR will be triggered if all the following conditions are met when the
relocation is output in a hard handover.
The switch of hard handover DSCR RncFeatSwitchBit4 is open.
The hard handover is needed according to the decision.
No CS service is included.
6.2.2 HSPA DSCR
In response to the incompatibility that may occur when equipment from different vendors
is interconnected via IUR, the RNC introduces HSPA DSCR for HSPA S/I/B services. If
the switch RncFeatSwitchBit15 is 0, the RNC will not process 1A/1C events of the
DRNC's cells. When Event 1D of the DRNC's cells is reported, the RNC will perform a
hard handover DSCR. Otherwise, HSPA DSCR is the same as R99 DSCR.
Handover Control Feature Guide
ZTE Confidential Proprietary 111
6.2.3 Common Status DSCR
To avoid the UE staying in common status continuously without any chance for
transferring large amount of data, the following strategy is introduced:
When the UE fails to transfer from common status to Cell_DCH status with the cause of
invalid configuration, if dscrInCmnToDedSwch is “1: On”, the RNC executes the DSCR
procedure, making the UE enter IDLE status and reestablish an RRC connection.
6.3 Coupling between relocation and DSCR
The DSCR is performed first when the conditions of relocation and DSCR are met
simultaneously.
DSCR and hard handover relocation
If there are only PS services, a DSCR is performed when the conditions of
relocation and DSCR are met simultaneously.
If there exists CS services, a relocation is performed.
DSCR and soft handover relocation
If there are only PS services, when the conditions of DSCR are met, a DSCR
is performed.
If there is only CS service, a relocation is performed.
For multi-RAB services, if DSCR conditions of PS service are met, then a
DSCR is performed after CS service is released.
6.4 Special Handling Strategy of IUR
6.4.1 Special Events Processing via IUR for PS0/0
In response to the incompatibility that may occur when IUR exists between different
vendors, for PS0/0 service, the SRNC executes “Special Events Handling via IUR for
Handover Control Feature Guide
ZTE Confidential Proprietary 112
PS0/0” if the following conditions are met:
(1). RncFeatSwitchBit18 is set to “0”.
(2). PS0/0 service exists currently.
If these conditions are met, the SRNC will not process Event 1A/1C/1D or 2A/2B/2C of
the DRNC's cells, and releases PS0/0 service and deals with the follow-up reported
events.
6.4.2 Special inter-frequency handover strategy via IUR for HSPA
When the current services of the UE include HSPA services, but the configuration of Iur
does not support the HSPA process, an inter-frequency handover via IUR needs to be
performed (not support “Relocation UE involved” or “Hard handover DSCR”):
If RNCFEATSWITCHBit24 (UIurLink) is set to “0: Not support HSPA fallback procedure
for inter-frequency handover via IUR”, an inter-frequency handover is performed together
with an HSPA transfer to DCH.
If RNCFEATSWITCHBit24 (UIurLink) is set to “1: Support HSPA fallback procedure for
inter-frequency handover via IUR”, an inter-frequency handover is performed after HSPA
is fallen back to DCH.
7 GSM Inter-RAT Handover Policy
Inter-RAT handover is the procedure which an UE handovers from one radio access
system to another, and specifically, from a UTRAN access system to an RATx system.
Inter-RAT handover can be a measurement-based handover between systems or a blind
handover based on GsmShareCover(Overlap or Covers).
The prerequisite of measured-based inter-RAT handover is that the UE measures the
quality of the Inter-RAT neighboring cells. In WCDMA system, for Inter-RAT
measurements in CELL_DCH state, the UE must enable compressed mode for
Inter-RAT measurements unless it has dual receivers. In addition, regarding the
influence of compressed mode on the system and UE, an inter-RAT measurement is
Handover Control Feature Guide
ZTE Confidential Proprietary 113
enabled only when the current UTRAN system has poor radio quality. The radio quality of
the current UTRAN system can be measured by four indicators, namely, uplink BLER,
uplink transmit power of the UE, downlink transmit power, and inter-frequency
measurement (quality measurement on the PCPICH by the UE). When receiving the
inter-RAT measurement result reported by the UE, the RNC makes an inter-RAT
handover decision and handovers the UE to the target cell specified in the measurement
result.
7.1 Inter-RAT Measurement
To avoid measurement fluctuations, the UE must perform layer 3 filtering on the
measurement result, and then use the filtered value for event decision and reporting. The
FilterCoeff (If the measurement is an event-triggered measurement and the
measurement quantity is EcNo, this parameter is obtained from URatEcNoEvMeasforG.
If the measurement is an event-triggered measurement and the measurement quantity is
RSCP, this parameter is obtained from URatRscpEvMeasforG. For a periodical
measurement, if the measurement quantity is EcNo, this parameter is obtained from
URatEcNoPrdMeas. If the measurement quantity is RSCP, this parameter is obtained
from URatRscpPrdMeas) is used as the layer 3 filtering factor for intra-system
measurements, and the GsmFilterCoeff(For an event-triggered measurement, if the
measurement quantity is EcNo, this parameter is obtained from URatEcNoEvMeasforG.
If the measurement quantity is RSCP, this parameter is obtained from
URatRscpEvMeasforG. For a periodical measurement, if the measurement quantity is
EcNo, this parameter is obtained from URatEcNoPrdMeas. If the measurement quantity
is RSCP, this parameter is obtained from URatRscpPrdMeas) is used for GSM system
measurements. The principles are the same as the formula for co-frequency
measurement.

7.1.1 Overview of Inter-RAT Measurement
Inter-RAT measurement is intended to measure inter-RAT cells. In an Inter-RAT
measurement, the measurement quantity of the UTRAN network can be triggered by the
measurement quantity of EcNo or RSCP, or both. Which parameter is used is controlled
by the NonIntraMeasQuan(UUtranCellFDD) parameter. The measurement quantity of
Inter-RAT measurement depends on the systems to be measured. For the GERAN, the
measurement quantity is RSSI.
3GPP defies a series of Inter-RAT measurement events. An UE reports the
corresponding events when the defined conditions are met.
3A: The currently used UTRAN carrier quality is lower than a threshold, and the quality of
other radio systems is higher than a threshold. It is used for decision of Inter-RAT
handover.

be reported as this event. In this way, improper reporting of Inter-RAT events resulting
from carrier quality fluctuation can be avoided.
7.1.2 Control Methods for Inter-RAT Measurement
7.1.2.1 Measurement Setup
The principles for setting up an inter-RAT measurement (service-based Inter-RAT
handover) depend on the value of the service handover IE in the RAB assignment
request message.
When the value of the service handover IE is “Handover to GSM should be
performed”, it indicates that the RAB should switch to the GSM system as soon as
possible. During the service setup or intra-system handover of such a service, if the
serving cell has a GSM neighboring cell and the inter-frequency measurement is not
enabled after the service setup or handover is successful, the RNC enables the
inter-RAT measurement immediately. (Note: The startup policy of service-based
inter-RAT measurements is not checked in the following scenarios:
i. A soft handover succeeds.
ii. Incoming compressed mode relocation of soft handovers is enabled.
When the value of the service handover IE is “Handover to GSM should not be
performed”, it indicates that the RAB can switch to the GSM only when it exceeds
the bearing capability of the UMTS. For such a service, the RNC enables the
inter-RAT measurement only when the quality of the UMTS system is poor. The
specific scenarios are described as follows:
The current working carrier is in poor quality (the measurement method is
described in “5.3 Downlink Coverage Based Inter-Frequency Handover”), but
the conditions for enabling inter-frequency measurements (that is, the
inter-frequency neighboring cell is not configured) or for inter-frequency blind
handover are not met. In this case, if the inter-RAT measurement is not
Handover Control Feature Guide
ZTE Confidential Proprietary 117
enabled or the conditions for inter-RAT blind handover are met but the blind
handover fails, an inter-RAT measurement is set up.
The inter-frequency measurement is enabled, and all non-working carriers
trigger 2E events. In this case, if the conditions for inter-RAT blind handovers
are not met and inter-RAT neighboring cells exist, or the conditions for
inter-RAT blind handovers are met, but the blind handover fails, the
inter-frequency measurement is disabled, and an inter-RAT measurement is
set up.
When the value of the service handover IE is “Handover to GSM shall not be
performed”, it indicates that the service cannot be switched to the GSM. For such a
service, the RNC does not enable the inter-RAT measurement or trigger a handover
to GSM.
The parameter srvBasedHoInd(ULogicalRnc) indicates whether the RNC supports
handovers based on service and ServHoSwch(UCelInfoFDD) is used to control
whether a cell open the function. For UEs in macro diversity state,
ServHoSwch(UCelInfoFDD) in the best cell is taken. If the best cell changes,
parameter configuration must be updated.
Service handover strategy controlled by RNC
When IE “service handover” is not included in RAB Assignment Request, the RNC
can perform the service handover strategy by using the parameter
srvHoIndAmr/srvHoIndCs64/srvHoIndPsNRT/srvHoIndPsRT(USrvBasedHo):
If the parameter is set to “Ignore service handover IE”, the RNC will ignore
“service handover” IE in requested RAB, and perform the strategy according to
the value of amrSrvHoStra/cs64SrvHoStra/psRtSrvHoStra/psNrtSrvHoStra
(USrvBasedHo). If the parameter is set to “Apply service handover IE” and
“service handover” is not included in the requested RAB, the RNC will also
perform the corresponding service handover strategy according to the value of
amrSrvHoStra/cs64SrvHoStra/psRtSrvHoStra/psNrtSrvHoStra
(USrvBasedHo). Otherwise, the RNC will perform the strategy based on the
value of “service handover” IE in the requested RAB.
Handover Control Feature Guide
ZTE Confidential Proprietary 118
Four service types (AMR/CS64/PS RT/PS NRT) are classified in this strategy
and the RNC performs service handovers according to the parameter
amrSrvHoStra/cs64SrvHoStra/psRtSrvHoStra/psNrtSrvHoStra(USrvBasedHo.
For multi-RAB services, srvHoComStra(USrvBasedHo) is used to control the
combination of service handover values. For example, if the service handover value
of AMR is “Handover to GSM should be performed”, and the value of PS RT service
is “Handover to GSM should not be performed”, the priority of “Handover to GSM
should not be performed” can be set to at a higher level than “Handover to GSM
should be perform”. When AMR and PS RT services are set up simultaneously, the
WCDMA carries the services. Only after the PS RT service is released, the CS
voice service can be handed over to the GSM based on the service handover value.
7.1.2.2 Measurement Modification
After the inter-RAT measurement is enabled, the measurement is changed in the
following cases:
After a soft handover, if the inter-RAT measurement parameters and inter-RAT
neighboring cells are changed, the inter-RAT measurement parameters and
inter-RAT neighboring cell list are updated by means of measurement modification.
When a service is added or deleted, if the handover parameters for a single service
or concurrent services are different, the inter-RAT measurement parameters must
be updated by means of measurement modification.
7.1.2.3 Measurement Deletion
Before the hard handover, inter-RAT measurement is enabled. Terminate the
inter-RAT measurement.
After soft handover, inter-RAT measurement is terminated in any of the following
cases:
The cell in the active set does not have inter-RAT neighboring cells.
Handover Control Feature Guide
ZTE Confidential Proprietary 119
The inter-RAT neighboring cells and the cells in the current active set are
neighboring cells with GsmShareCover(Covers).
The inter-RAT neighboring cells and the intra-frequency neighboring cells of
the cells in the current active set are neighboring cells with
GsmShareCover(Covers).
When the service handover value of the service is “Handover to GSM should not be
performed” and the quality of the working carries becomes better (the measurement
method is the same as that described in “5.1.2.3 Measurement Deletion”),
compressed mode is closed, and the GSM measurement is terminated.
In the case of exceptions, for example, an exceptional report of the inter-RAT
measurement task (for example, an unavailable measurement task is received from
the network side), the corresponding inter-RAT measurement is released.
When the RNC sends a MEASUREMENT CONGROL RELEASE message for a
measurement ID, the time stamp is recorded. If the RNC receives the measurement
report for the ID, it compares the current time and the recorded time. If the difference
between the current time and the recorded time exceed the threshold
TResndMeaCtrlRel(URncFunction) configured, the MEASUREMENT CONTROL
RELEASE will be resent. Otherwise, this measurement report will be ignored.
7.1.2.4 Processing of Inter-RAT Events
Processing of 3A/3C events
1) In a cell, inter-RAT handovers can only be triggered by 3A or 3C events, which is
controlled by the inter-RAT handover tactic RatHoTactic(UUtranCellFDD).
2) For GSM handover, when the inter-RAT handover fails, the penalty timer
HoToGsmPenTimer, which is specific to the UE, is started. The RNC will not
process the reported inter-RAT measurement reports before the timer expires, and
will issue new inter-RAT measurement control messages after the timer expires.
When PS service exists, if the UE supports inter-RAT PS service handover and the
parameters psInterSysHoSuppInd(ULogicalRnc) and BSCPSFeatSwitch(UIurgLink)
in the OMCR indicates that the RNC and adjacent BSCs support PS service
Handover Control Feature Guide
ZTE Confidential Proprietary 120
handover respectively, the HANDOVER FROM COMMAND process is used (See
“CS Service Handover from 3G System to 2G System” process). Otherwise, the cell
reselection process of PS service handover is used (See “PS Service Reselection in
3G to 2G Handover” process). In the cell reselection of PS service handover
process, the inter-RAT cell reselection time can be decreased by the NACC, which
means that system information of the target GERAN cell is carried in the CELL
CHANGE ORDER FROM UTRAN message sent from the RNC to the UE, assisting
the UE in the inter-RAT cell reselection process. The NaccSuppInd(ULogicalRnc)
parameter indicates that whether the RNC supports the NACC function.
GeranCellInd(UExternalGsmCell) indicates whether a GSM cell is a GERAN cell.
When CS service and PS service exist simultaneity, if the UE supports inter-RAT
DTM handover and the parameters DtmSuppInd(ULogicalRnc) and
BSCDTMFeatSwitch(UIurgLink) in the OMCR indicates that the RNC and adjacent
BSCs support DTM handover, the HANDOVER FROM COMMAND process is used
to hand over concurrent services to the 2G system. Otherwise, PS services are
suspended firstly, and then CS service is handed over to the 2G system and PS
services are handed over to the 2G system in sequence.
Note: When the IE “inter-rat cell info indication” is filled into the measurement control
message, if the value of IE “inter-rat cell info indication” in the inter-RAT measurement
report reported by the UE is different from that filled in the measurement control message,
this measurement report will not be processed when RatCelInfoSwch is “0”, but be
processed when RatCelInfoSwch is “1”.
7.1.2.5 Policy for Setting Inter-RAT Measurement Parameters
Policy for setting Inter-RAT event parameters
There are four inter-RAT measurement events (3A, 3B, 3C, 3D). The EventNum (If
the measurement quantity is EcNo, this parameter is obtained from
URatEcNoEvMeasforG. If the measurement quantity is RSCP, this parameter is
obtained from URatRscpEvMeasforG) parameter controls the number of the events
to be configured. The EventId (If the measurement quantity is EcNo, this parameter
is obtained from URatEcNoEvMeasforG. If the measurement quantity is RSCP, this
parameter is obtained from URatRscpEvMeasforG) parameter controls the specific
Handover Control Feature Guide
ZTE Confidential Proprietary 121
events to be configured. The EventId parameter is defined through array, and the
dimensions of array are equal to EventNum, which is 4 at most.
Handover parameter configuration strategy in macro diversity:
Measurement parameters are based on cells. Therefore, in the case of macro
diversity, the measurement parameters configured for the best cell are used as
handover parameters. If the best cell changes, the measurement parameters must
be updated.
For inter-RNC handover, if an SRNC cell exists in the active set, the measurement
parameters of the best cell in the SRNC will be used as handover parameters. If
there is no SRNC cell in the active set, the measurement parameters of the last
SRNC cell in the active set will be used as handover parameters.
Setting of multiple sets of handover parameters
inter-RAT handover parameters can be configured separately according to the
measurement quantity, measurement reporting mode, and service bearer type. In
this way, multiple sets of measurement parameters are required for different
purposes. The classification is as follows:
Measurement quantity of the UTRAN
NonIntraMeasQuan(UUtranCellFDD) (CPICH RSCP or EcNo or both
of them)
Note:
When NonIntraMeasQuan is configured as “EcNo” or “RSCP”, only the 2D/2F
events corresponding to the measurement quality are issued.
When NonIntraMeasQuan is configured to “EcNo and RSCP”, two categories of
2D/2F measurement events about CPICH EcNo and CPICH RSCP are configured
and one of 2D measurement events can trigger compressed mode. After
compressed mode is triggered, inter-RAT events of corresponding measurement
quantity will be issued according to that of 2D event. For example, if the
measurement quantity of triggering 2D event is CPICH Ec/No, only inter-RAT events
Handover Control Feature Guide
ZTE Confidential Proprietary 122
of CPICH EcNo will be issued.

(3). When the above principles are met simultaneously, the first one prevails.
For ease of parameter modification and optimization, inter-RAT handover parameters
are arranged by indexes. The indexing relations are shown in the figure below.

Note: When a new cell is set up, the value of intialHoCelSelScene(URatMeasProfile)
(0:Outdoor Scene, 1:High-Mobility Outdoor Scene, 2:Indoor Scene, 3:Subway/tunnel
Scene) is determined according to the actual cell scene (indicated by
HoCelSelScene(UUtranCellFDD)), and the available inter-RAT measurement profile
corresponding to intialHoCelSelScene is configured for the cell.
Before inter-RAT handover parameters are obtained, profileId(URatMeasProfile) of
the cell is found based on refURatMeasProfile(UUtranCellFDD), and then, in
URatMeasProfile configuration items, the next level managed object is obtained
according to the current measurement application type: For event-triggered
measurements, “Inter-RAT Measurement Configuration Related to Traffic Category
Object ID (URatMeasSrvSpec)” is selected. For periodical measurement, “Inter-RAT
Measurement Configuration Unrelated to Traffic Category Object ID
(URatMeasNoSrvSpec)” is selected.
Handover Control Feature Guide
ZTE Confidential Proprietary 124
In the managed object decided above, “Inter-RAT Measurement Configuration No.
(InterRatCfgNo)” is found based on “Traffic
Category(srvCategory(URatMeasSrvSpec))” and “Measurement
Quantity(NonintraMeasQuan)”. Finally, the corresponding inter-RAT handover
measurement parameters are found. The details are as follows:
(1). For event-triggered measurements:
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object URatEcNoEvMeasforG.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object URatRscpEvMeasforG.
(2). For periodical measurements:
If the measurement quantity is EcNo, the measurement parameters are obtained
from the managed object URatEcNoPrdMeas.
If the measurement quantity is RSCP, the measurement parameters are obtained
from the managed object URatRscpPrdMeas.
The relations between the other parameters to be entered in the inter-RAT
measurement control message and the OMCR parameters are as follows:
Measurement report transmission mode MeasRptTrMod
GSM BSIC acknowledgement indication for
inter-RAT measurement BSICVeriReq
UTRAN quality estimation reporting
indication UtranEstQual
GSM cell RSSI reporting indication GsmCarrRSSIInd
Note: The Measured Quantity for UTRAN quality estimation in Inter-RAT
measurement and Measurement Report Criteria are automatically entered based
on InterRatCfgNote. The values of these parameters are for maintenance
personnel‟s reference.
Switch of inter-RAT handover based on measurement for different services
Handover Control Feature Guide
ZTE Confidential Proprietary 125
There are several switches for different services to control whether different
measurement-based RATx handovers can be performed. When such a switch is
open, it is allowed to perform RATx handovers for the corresponding service.
Otherwise, the RNC forbids inter-RAT handovers for the service by not activating
the inter-RAT measurement. The switches for different services are described as
followed:
Service Switch
AMR amrRatHoSw(ULogicalRnc)
R99 RT r99RtRatHoSw(ULogicalRnc)
R99 NRT r99NrtRatHoSw(ULogicalRnc)
HSDPA hsdpaRatHoSw(ULogicalRnc)
HSUPA hsupaRatHoSw(ULogicalRnc)
7.1.3 Neighboring Cells Configuration
During the 2G neighboring cells configuration, the neighboring cell list used for
reselection in non-CELL_DCH state and for handover in CELL_DCH state can be
configured separately. During handovers, target cells are selected by neighboring cells
configuration state (GsmStateMode(UGsmRelation)). When the UE is in macro diversity
state, the neighboring cell list is a combination of neighboring cell lists of each cell‟s
active set, so the number of inter-RAT neighboring cells may exceed 32, which is the
maximum number specified by the protocol. If the number of inter-RAT neighboring cells
exceeds 32, some cells must be deleted to ensure that there are only 32 inter-RAT
neighboring cells. With minimal impact on the UEs in the active set, these dropped cells
are those with poorer signal quality or remoter geographical location. Therefore, each
inter-RAT neighboring cell is configured with a priority.
7.1.3.1 Cell Priority Configuration
The MeasPrio(UGsmRelation) parameter defines the priority of an 2G neighboring cell
with three values: 0 (high), 1 (medium), or 2 (low). The value can be determined by
network planning engineers according to the existing network conditions, for example,
the quality and geographic location of the inter-RAT neighboring cell. The value 0 shows
the priority settings of inter-RAT neighboring cells based on geographic locations. The
gray cell in the center of the following figure is the source cell. It has three layers of
Handover Control Feature Guide
ZTE Confidential Proprietary 126
inter-RAT neighboring cells, marked respectively in yellow, blue, and red. The inter-RAT
neighboring cells in yellow have the highest priority level, namely, 0. Those in blue have
the secondary highest priority level, namely, 1. Those in red have the lowest priority level,
namely, 2.
Figure 7-2 Priority Settings of Cells
Source Cell
Priority 0
Priority 1
Priority 2
7.1.3.2 Strategy for Adjacent Cells Exceeding 32
The related standards stipulate that the maximum number of 2G neighboring cells is 32.
When an UE is in macro diversity state, the number of inter-RAT neighboring cells of
multiple cells in the macro diversity may exceed this limit. Therefore, a specific policy is
needed to delete neighboring cells. The policy involves combination, selection, and
deletion of the neighboring cells with the same priority.
Priority combination
If a cell is a common neighboring cell of multiple cells in the active set, it may be
configured with different priority levels in different cells. In this case, the multiple priority
levels of this cell must be combined, using the highest priority level as the priority of this
cell.
Neighboring cell list update and deletion in the case of more than 32 neighboring
cells
Handover Control Feature Guide
ZTE Confidential Proprietary 127
If the inter-RAT neighboring cell list of an active list contains more than 32 cells, the cells
are sorted in descending order based on priority. The first 32 cells remain unchanged,
and all other cells are put into the reserved inter-RAT neighboring cell list, which can
buffer at most 8 truncated inter-RAT cells.
Each time when the 1A, 1B, 1C, or 1D event is triggered, the priority levels of the
neighboring cells in the inter-RAT neighboring cell list are updated. If there are less than
32 cells in the inter-RAT neighboring cell list after the 1B event is triggered, the cells with
the highest priority in the reserved inter-RAT neighboring cell list are put into the
inter-RAT neighboring cell list. The number of the cells from the reserved inter-RAT
neighboring cell list equals: min(32 – number of existing cells in the inter-RAT
neighboring cell list).
7.2 Inter-RAT Handover Based on Downlink Coverage
Downlink coverage uses 2D and 2F events as the criterions for evaluating the signal
quality of the current frequency.
For GSM handovers, the RNC transmits the 2D ad 2F event configuration to the UE
when the service is set up. If the UE reports a 2D event, that is, the current carrier is in
poor signal quality, and no inter-frequency neighboring cells exist, or the UE reports a 2E
event after inter-frequency measurement is started (that is, the signal quality of the
measured inter-frequency neighboring cell is also poor), the RNC tries to initiate an
inter-RAT blind handover first if inter-RAT neighboring cells with
GsmShareCover(UGsmRelation)( Covers) exist. If inter-RAT neighboring cells exist but
have no GsmShareCover(Covers) relation, or the blind handover fails, the RNC needs to
configure and start an inter-RAT measurement 3A or 3C event to the UE, and then
performs the corresponding decision process for inter-RAT handover according to the 3A,
or 3C event subsequently reported by the UE.
7.3 Inter-RAT Handover Based on Uplink BLER
The RncUlBlerHoSwch and UlBlerHoSwch(UUtranCellFDD) parameters control the
enabling of uplink BLER based handovers.
Handover Control Feature Guide
ZTE Confidential Proprietary 128
This policy is specific to DCHs.
When the values of RncUlBlerHoSwch and UlBlerHoSwch(UUtranCellFDD) are both
“ON”, the RNC periodically measures the uplink BLER. If the measured uplink BLER is
higher than a certain threshold (1.25%), and the real-time measured value (Sirtarget)
reaches the maximum value of the BAM (ULMaxSIR), the RNC triggers the inter-RAT
measurement or handover policy. The process is the same as that for inter-RAT
handover based on downlink coverage.
7.4 Inter-RAT Handover Based on Uplink Transmit
Power
The RncTxPwrHoSwch and UlPwrHoSwch(UUtranCellFDD) parameters control the
enabling of inter-frequency handovers based on uplink transmit power.
Handover Based on Uplink Transmit Power is used only for traffic carried on DCHs.
When the values of RncTxPwrHoSwch and UlPwrHoSwch(UUtranCellFDD) are both
“ON”, the RNC sets up a UE internal measurement while services are initially established.
The UE internal measurement mainly measures the UE transmission power (TxP) by
event report.
Before UE internal measurement parameters are obtained, profileId(UUeIntMeasProfile)
of the cell is found based on refUUeIntMeasProfile(UUtranCellFDD). Then, according to
the current measurement purpose “UE Transmitted Power Event Measurement for
Handover”, the managed object UHoEvtTPUeInt is obtained from UUeIntMeasProfile
configuration items. Finally, “UE Internal Measurement Configuration
Index(UeIntMCfgNo(UHoEvtTPUeInt))” and the following corresponding internal
measurement parameters are obtained from UHoEvtTPUeInt.
Measurement Report Transfer Mode measRptTrMod(UHoEvtTPUeInt)
Filter Coefficient filterCoeff(UHoEvtTPUeInt)
Maximum Event Number of UE Internal Measurement measEvtNum(UHoEvtTPUeInt)
UE Internal Measurement Event Identity meaEvtId(UHoEvtTPUeInt)
Handover Control Feature Guide
ZTE Confidential Proprietary 129
Time to Trigger(ms) trigTime(UHoEvtTPUeInt)
When the transmit power of the UE meets the above threshold requirements, the UE
reports the corresponding events. After receiving an Event 6A report (Uplink power of UE
exceeds txPowerThres(UHoEvtTPUeInt)) or an Event 6B report (Uplink power of UE is
less than txPowerThres(UHoEvtTPUeInt)), the RNC uses the same processing strategy
as that of 2D or 2F, respectively. For details, see the Events 2D and 2F processing
strategies in “Inter-RAT Handover Based on Downlink Coverage”.
7.5 Inter-RAT Handover Based on Downlink Transmit
Power
The RncTxPwrHoSwch and DlPwrHoSwch(UUtranCellFDD) parameters control the
enabling of inter-frequency handovers based on downlink transmit power.
This policy is specific to DCHs.
When the values of RncTxPwrHoSwch and DlPwrHoSwch(UUtranCellFDD) are both
“On”, the RNC will check the DTCP in the Node B dedicated measurement report.
Obtaining of the Node B dedicated measurement parameters: According to the current
measurement purpose “Event A Report Parameters for TCP in Handover Control”/”
Event B Report Parameters for TCP in Handover Control”, the following parameters used
for handover control are obtained from the sub-object UNbDedMeas of the object
UNbDedMeasProfile:
Dedicated Measurement Type DedMeasType (UNbDedMeas)
Measurement Change Time /Measurement
Hysteresis Time EvtAbcdefTime (UNbDedMeas)
Measurement Filter Coefficient MeasFilterCoeff (UNbDedMeas)
Report Period RptPrd(UNbDedMeas)
Choice Report Periodicity Scale RptPrdUnit (UNbDedMeas)

Handover Control Feature Guide
ZTE Confidential Proprietary 130
Measurement Threshold of Event A/B for Transmitted
Code Power EvtAbTcpThrd(UNbDedMeas)
NbDed Measure Configuration No NbDMCfgNo(UNbDedMeas)
If the DTCP reaches the threshold of Event A, it indicates the downlink power is very high,
the processing strategy is the same as that of Event 2D. If the DTCP reaches the
threshold of Event B, the processing strategy is the same as that of Event 2F. For details,
see “inter-RAT handover based on downlink coverage”.
7.6 Handover Based on Load Control
The RNC selects some users with lower priority levels in the cell and switches them to
the neighboring cells with GsmShareCover (Overlap or Covers) blindly in case of the
following conditions:
When the load (transmitted carrier power (TCP) or received total wideband power
(RTWP)) of a cell is rather high.
If the current neighboring cell does not have any inter-frequency neighboring cell
with ShareCover (Overlap or Covers), but has inter-RAT neighboring cells with
GsmShareCover (Overlap or Covers), the RNC selects some users with lower
priority levels in the cell and switches them to the neighboring cells with
GsmShareCover (Overlap or Covers) blindly.
In this way, the system load can be reduced quickly and the system reliability can be
guaranteed. For details about the inter-system handover based on load, refer to the ZTE
UMTS Load Balance Feature Guide.
7.7 UMTS->GSM Handover Based on Board Power Off
No matter whether the board power is off or board property is changed, services and
users in the corresponding board will be all dropped off, which will influence user
experience. Therefore, the waiting timer is set to control the time of turning off power
when the board power is off.
Handover Control Feature Guide
ZTE Confidential Proprietary 131
Whether a board is powered off is indicated by a notification flag (the flag for UE based
on saving energy or property changed, for details see “ZTE UMTS Intelligent Carrier
Power Control Feature Guide”).
When the notification flag is “True”, the timer BoardPwrOffHoTmr(URncFunction) is
started. For CS services, if there are 2G neighboring cells and all the relative inter-RAT
switches are open, Event 3C will be used in inter-RAT measurements to make the
service handovers to 2G network as soon as possible. For the other CS services that do
not meet the conditions of inter-RAT handovers, are released immediately. For PS
services, a DSCR is directly performed. After the timer expires, all the services in the
system will be released.
7.8 Inter-RAT Handover based on GSM Load
After IUR-G is introduced, the UMTS can acquire the load conditions in the GSM when
IurgFeatSwitch(UIurgLink) indicates that adjacent BSCs support the Iur-g signaling
procedure, so inter-RAT handover based on GSM load is taken into consideration to
avoid admission failure in the GSM because of overload in the GSM system. This
function is controlled by the parameter LdBsIntSysHOInd(ULogicalRnc).
7.8.1 Acquirement and Update of GSM Load Condition
3GPP defines three categories of GSM load in IUR-G: Load Value, RT Load, and NRT
Load. Load Value is about total load condition in cell, while RT Load for RT service load
and NRT Load for NRT service load.
GSM overload cell saving and update strategy
Defining the RT overload cell list and GSM overload cell list, the RNC saves and updates
the two lists in time, and sets up the overload valid timer CellLdInfoVldTim
(URncFunction). When the duration of a cell‟s overload information before an update
exceeds CellLdInfoVldTim(URncFunction), the cell will be deleted from the
corresponding overload cell list.
When the reported downlink RT Load in a GSM cell is not less than GsmDlRTLdThrd
(UExternalGsmCell) or the reported uplink RT Load in a GSM cell is not less than
Handover Control Feature Guide
ZTE Confidential Proprietary 132
GsmUlRtLdThrd (UExternalGsmCell), it means that the load in the GSM cell is heavy and
RT services cannot be accessed. The cell will be kept in the RT overload cell list. If the
reported uplink/downlink RT Load is smaller than the corresponding threshold in a cell
and the cell exists in the RT overload cell list, the cell will be deleted from the RT
overload cell list.
When the reported downlink load in a GSM cell is not less than GsmDlLdThrd
(UExternalGsmCell) or the reported uplink load in a GSM cell is not less than
GsmUlLdThrd (UExternalGsmCell), it means that any service cannot be accessed, and
the cell will be kept in the GSM overload cell list. If the reported uplink/downlink load is
smaller than the corresponding threshold in a cell and the cell exists in the GSM overload
cell list, the cell will be deleted from the GSM overload cell list.
For RT services, if the RT Load is reported, it is used to decide the load conditions of the
GSM cell. Otherwise, the Load Value is used to decide the conditions. For NRT services,
the Load Value is used to decide the load conditions of the GSM cell.
7.8.2 Inter-RAT Handover based on GSM Load Process
Under the following scenarios, the target cell list for handovers is selected. If a target cell
is included in the overload cell list, it is considered that the GSM cell is overloaded and
the handover to the cell is not triggered. Another cell in the candidate cells list will be
selected instead. If all cells in the candidate cells list do not satisfy the handover
conditions, the corresponding handover is not performed.
Inter-RAT handover based on quality of downlink coverage, uplink BLER, and
uplink/downlink transmit power.
Inter-RAT handover based on load control.
Inter-RAT handover based on load balance.
Note: For RT services, if the GSM reports RT information, the overload-cell list stands for
the RT overload-cell list. Otherwise, if the GSM does not report RT information, the
overload cell list stands for the GSM overload-cell list. For NRT services, the
overload-cell list means the GSM overload-cell list.
Handover Control Feature Guide
ZTE Confidential Proprietary 133
7.9 Special UMTS->GSM Handover Strategy based on
the Indoor Neighboring Cell
For a 3G cell within the present network, when the indoor neighboring cells exist, if the
processing strategy for ordinary 2G neighboring cells is still used, call drops may occur
before a handover can be performed. Therefore, for different 2G neighboring cells of the
one 3G cell, different 2D triggering thresholds are configured and different inter-RAT
measurement events are issued. In this way, timely handovers can be performed
immediately in response to the signal changes of indoor cells whenever an indoor cell
that meets the conditions exists.
If the following conditions are met, the special UMTS->GSM handover strategy should be
performed, which means issuing two sets of 3A/3C events simultaneously. Only 3A event
is processed by ordinary 2G neighboring cells, and 3C/3A events are both processed by
indoor 2G neighboring cells.
(1) RatHoTactic is “0: determined by algorithm”.
(2) There is at least one GSM neighboring cell whose IndoorCellInd is “1: indoor
cell”.
(3) The value of “service handover” is not “handover to GSM should be performed”.
7.10 Coupling for Different Handover Causes
As described above, the causes of 2G handovers include the following:
Handover based on load control
Handover based on downlink coverage/quality event
Handover based on uplink transmit power
Handover based on uplink BLER
Handover based on downlink transmit power
Handover Control Feature Guide
ZTE Confidential Proprietary 134
Handovers based on load control aim to reduce the system load quickly to ensure
system stability. Therefore, handovers based on load control has the highest priority. The
handover triggered by radio quality causes such as downlink coverage event, uplink
transmit power, uplink BLER, and downlink transmit power aim to ensure the QoS and
user experience. Handovers of this kind have the second highest priority.
The handover of higher priority shields the handover of lower priority, for example, a cell
handed over based on load control cannot admit new services.

handovers can be processed via IUR-G, which is added with this procedure. The
Handover Control Feature Guide
ZTE Confidential Proprietary 136
procedure is the part of the previous CN procedure between the RNC and the BSC to
reserve resources in advance. The procedure is described as follows:
1 Upon receiving the measurement report of the UE, the RNC decides to handover
the UE to a GSM cell.
2 The RNC sends an ENHANCED RELOCATION RESOURCE REQUEST message
to the BSC, requiring resources for the UE.
3 Upon receiving the message, the BSC reserves resources in advance for the UE
and sends an ENHANCED RELOCATION RESOURCE RESPONSE message to
the RNC.
4 Upon receiving the message, the RNC sends a RELOCATION REQUIRED
message to the CN and sends HANDOVER FROM UTRAN COMMAND to the UE,
requiring the UE to perform a hard handover.
5 Described in step 4.
6 Upon receiving the message RELOCATION REQUIRED, the CN sends a
HANDOVER REQUEST message to BSC.
7 After the resources are established, the BSC sends a HANDOVER REQUEST ACK
message to CN.
8 Upon receiving the message HANDOVER REQUEST ACK, the CN sends a
RELOCATION COMMAND message to the RNC.
9 Upon receiving the message RELOCATION COMMAND, the RNC sends a
RELOCATION COMMIT message to the BSC.
10 Upon receiving the message HANDOVER ACCESS from the UE, if the BSC has
already received the message RELOCATION COMMIT from the CN, the BSC will
send a HANDOVER DETECT to the CN. Otherwise, the BSC will not send
HANDOVER DETECT to the CN until receiving the message RELOCATION
COMMIT from the CN.
11 Described in step 4.
Handover Control Feature Guide

12 The UE returns “HANDOVER COMPLETE” to the BSC to inform the BSC that the
handover is finished.
13 After receiving HANDOVER COMPLETE from the UE, the BSC sends a
HANDOVER COMPLETE message to the CN.
14 Upon receiving the message HANDOVER COMPLETE, the CN sends an “IU
RELEASE COMMAND message to the RNC to release all the Iu resources.
15 Upon releasing the lu resources, the RNC returns IU RELEASE COMPLETE to the
CN.
Note: In the process of a 3G->2G CS service handover, the parameter rxlevNecellInd
(URncInfo) is used to control whether to fill the IE “RXLEV-NECELL” in
oldBSS_ToNewBSS of the RELOCATION REQUIRED message. When rxlevNecellInd
(URncInfo) is “1:On”, the IE is filled to allow the GSM to select suitable frequency.
7.11.2 PS Service Reselection in 3G to 2G Handover
If UE doesn‟t support inter-RAT PS service handover or adjacent BSC doesn‟t support
PS service handover, handover of PS domain from the UTRAN to the GSM can be
classified into the following cases:
The UE actively initiates the PS service reselection.
The UE selects a GPRS cell to dwell through the cell reselection process, sets up a
connection with the target cell, and then initiates route area update. This case applies to
an UE in CELL_FACH or URA_PCH state.

The RNC decides to switch the UE to another RAT cell according to handover decision
results. This case applies to an UE in CELL_DCH state. The RNC sends a handover
command CELL CHANGE ORDER FROM UTRAN to the UE. After receiving the
command, the UE sets up a connection with the target cell, and then initiates route area
update.

3. The UE initiates the GPRS Routing Area Update procedure by sending the GMM
message Routing Area Update Request to the SGSN.
4. The SGSN sends the RANAP message SRNS Context Request to the SRNC listing
the PS RABs for which context transfer shall be performed.
5. SRNC responds to the SGNS with the RANAP message SRNS Context Response
containing the context information of all referenced PS RABs whose transfer is
successful and starts the timer TWaitDataFwd(URncFunction). Upon reception of
the SRNS Data Forward Command message, SRNC shall stop the timer. If
TWaitDataFwd expires, SRNC starts the timer TWaitRelCmd(URncFunction).
6. The SGSN asks the SRNC to forward its buffered data back to the SGSN by
sending the RANAP message SRNS Data Forward Command, and starts the timer
Tdatafwd(UiuCnst) and TWaitRelCmd(URncFunction). If Tdatafwd expires, the
SRNC releases the resource used to forward buffered data. Upon reception of the
IU RELEASE COMMAND message, the SRNC shall stop the timer TWaitRelCmd. If
TWaitRelCmd expires, the SRNC releases IU connection. For each PS RAB
indicated by the SRNS Data Forward Command, the SRNC starts duplicating and
tunneling the buffered data back to the SGSN.
7. The SGSN sends the RANAP message Iu Release Command to initiate the release
of the Iu connection with UTRAN.
8. At the expiration of the RNC data forwarding timer (i.e. TDATAfwd), the SRNC
sends the RANP message Iu Release Complete message to the SGSN.
9. The SGSN validates the UE‟s presence in the new RA by sending the GMM
message Routing Area Update Accept to the UE. The message may contain a new
P-TMSI that the network assigns to the UE.
10. The UE acknowledges the assignment of a new P-TMSI by sending the GMM
message Routing Area Update Complete to the UE.

8 UTRAN<->LTE Handover Strategy
8.1 UTRAN<->LTE PS Handover Strategy
RNC adds the “UTRAN<->LTE PS Handover Strategy” to ensure the continuity of PS
service between UTRAN and LTE. If an UE switches from a RATx system to a UTRAN
system, the RATx system policy is used. So, there is only UTRAN->LTE PS handover
strategy described. For now, only support radio quality based inter-RAT (UTRAN->LTE)
handover.
The conditions as follow need to be fulfilled firstly if RNC wants to execute UTRAN->LTE
PS handover strategy:
1. Parameter RncPsHoLteSw (ULogicalRnc) is set to “1: open”.
2. Support of Inter-RAT PS Handover to E-UTRA FDD IE of UE capability indicates
that RNC supports PS service handover from UTARN to LTE.
3. The switch for current service to control whether LTE based on measurement could
be performed is open.
Service Switch
R99 RT r99RtEutraHoSw (ULogicalRnc)
R99 NRT r99NrtEtraHoSw (ULogicalRnc)
HSDPA hsdpaEutraHoSw (ULogicalRnc)
HSUPA hsupaEutraHoSw (ULogicalRnc)
4. The system which RNC allows UE to hand over to is “EUTRAN”, that is judged by
cell level switch IfOrRatHoSwch, ChoStraMulRatHo and the conditions of neighbor
cell exiting (See “5.10 Inter-frequency and Inter-RAT Measurement Choice”).
5. The switch of whether to check the UE E-UTRA Capability before initiating the PS
handover procedure from UMTS to LTE, GresPara52 (bit11) is “Off” or GresPara52
(bit11) is “On” with UE E-UTRA Capability IE acquired.
Note: In the process of UTRAN->LTE handover, EUTRAN cell is identified by eNode
BID or RNCID that is indicated by parameter LteCellIdenFlag (UIupsLink). When SGSN
Handover Control Feature Guide
ZTE Confidential Proprietary 142
cannot recognize eNode BID of EUTRAN Cell, set LteCellIdenFlag (UIupsLink) to “1”
using RNCID for EUTRAN cell.
8.1.1 EUTRAN Inter-RAT Measurement
UE must perform layer 3 filter on the measurement result, and then use the filtered value
for event decision and reporting. The principles are the same as description in “7.1
Inter-RAT Measurement”, the difference is introducing the eUtranFilterCoeff for LTE
system measurement.
8.1.1.1 Measurement Event and Parameter Configuration
After supporting UMTS->EUTRAN inter-RAT handover, introduce the specific manage
objects: UInterEcNoEvMeasforE, UInterRscpEvMeasforE, URatEcNoEvMeasforE, and
URatRscpEvMeasforE.
1 UInterEcNoEvMeasforE and UInterRscpEvMeasforE correspond to event 2D/2F for
EUTRAN, See “5.1.1 Introduction to Inter-Frequency Measurement” and “5.1.2.6
Parameter Configuration Strategies” for details of the definition of the events and
policy for parameter configuration.
2 URatEcNoEvMeasforE and URatRscpEvMeasforE correspond to the inter-RAT
measurement events 3A, 3C. See “7.1.1 Overview of Inter-RAT Measurement” and
“7.1.2.5 Policy for Setting Inter-RAT Measurement Parameters” for details of the
definition of the events and policy for parameter configuration. The differences are as
follow:
(1) For the ETRAN, the measurement quantity is RSRP.
(2) The measurement parameters are gained from the manage objects defied for
EUTRAN.

The other parameter to be entered in the inter-RAT measurement control message:
Maximum bandwidth allowed to measure on the single frequency of EUTRAN-
EutranNMeasBand (for FDD cell, this parameter is obtained from MO
UExternalEUtranCellFDD; for TDD cell, this parameter is obtained from MO
UExternalEUtranCellTDD).
8.1.1.2 Setting up a measurement
The principles for setting up an inter-RAT measurement depend on the value of the
E-UTRAN service handover IE in the RAB assignment request message.
1. When the value of the E-UTRAN service handover IE is “Handover to E-UTRAN
shall not be performed”, it indicates that the service cannot be switched to the
E-UTRAN. For such these services, the RNC does not enable inter-RAT
measurement or trigger the handover to LTE.
2. When the value of the E-UTRAN service handover IE is not “Handover to E-UTRAN
shall not be performed”, it indicates that the service can be switched to the E-UTRAN.
RNC enables inter-RAT measurement in the following scenarios:
a) Inter-frequency measurement is enabled, all non-working carriers trigger
2E events, and EUTRAN neighboring cells exist.
b) The event 2D for EUTRAN is reported.
8.1.1.3 Modifying a measurement
Same as “7.1.2.2 Modifying a measurement”.
Handover Control Feature Guide
ZTE Confidential Proprietary 145
8.1.1.4 Deleting a measurement
1. When the E-UTRAN service handover value of the service is “Handover to E-UTRAN
shall not be performed” and the quality of the working carries becomes better, the
compressed mode is closed, and E-UTRAN measurement is terminated.
2. Other deleting scenarios seen in “7.1.2.3 Deleting a measurement”.
8.1.1.5 Processing of Inter-RAT Events
1. See “7.1.2.4 Processing of Inter-RAT Events“ for the policy of “the choice of
inter-RAT measurement event” and “judge the IE inter-rat cell info indication”.
2. Use HANDOVER FROM UTRAN COMMAND process for UTRAN->EUTRAN PS
handover (See “8.1.5 UTRAN->EUTRAN inter-RAT handover process”). When
concurrent services exist, if any one of these services doesn‟t support inter-RAT PS
service handover, RNC will not handover to LTE.
3. When EUTRAN inter-RAT handover fails, the penalty timer HoToEutraPenTimer,
which is specific to UE, is started, RNC will not handle the reported inter-RAT
measurement reports before the timer expires, and issue new inter-RAT
measurement control message after the timer expires.
8.1.1.6 Neighbor Cells Screened
When Measurement Control message for EUTRAN measurement needs to be issued,
RNC will select the suit cells according to the capacity of UE.
8.1.2 EUTRAN Inter-RAT Handover Based on Downlink Coverage
Downlink coverage uses 2D and 2F events as the criterions for evaluating the signal
quality of the current frequency.
For EUTRAN handover, RNC transmits the 2D ad 2F event configuration for EUTRAN to
the UE when the service is set up. If the UE reports a 2D event, that is, the current carrier
is in poor signal quality, and no inter-frequency neighboring cells exist, or the UE reports
a 2E event after inter-frequency measurement is started (that is, the signal quality of the
Handover Control Feature Guide
ZTE Confidential Proprietary 146
measured inter-frequency neighboring cell is also poor), the RNC needs to configure and
start inter-RAT measurement 3A or 3C event to the UE if inter-RAT neighboring cells
exist, and then performs the corresponding decision process for inter-RAT handover
according to the 3A, or 3C event subsequently reported by the UE. The choice strategy
of events 3A, 3C is the same as the related policy of GSM inter-RAT handover, controlled
by inter-RAT handover tactic RatHoTactic (UUtranCellFDD).
8.1.3 EUTRAN Inter-RAT Handover Based on BLER and Transmit Power
See “7.3 Inter-RAT Handover Based on Uplink BLER”, “7.4 Inter-RAT Handover Based
on Uplink Transmit Power” and “7.5 Inter-RAT Handover Based on Downlink Transmit
Power”.
8.1.4 Coupling for Different Handover Causes
The causes of LTE handover include the following:
Handover based on downlink coverage/quality event
Handover based on uplink transmit power
Handover based on uplink BLER
Handover based on downlink transmit power
The handovers triggered by radio quality causes such as downlink coverage event,
uplink transmit power, uplink BLER, and downlink transmit power aim to ensure the QoS
and user experience. The handovers of these kinds has the same priority.

8.2 SRVCC
Due to the continuity of voice service between the UTRAN and the LTE, the RNC is
needed to transition a voice call from the VoIP/IMS packet domain to the legacy circuit
domain during an inter-RAT handover. This mechanism is named SRVCC (Single Radio
Voice Call Continuity).
ZTE supports SRVCC, which is controlled by RncSrvccSw(ULogicalRnc), from LTE to
UTRAN.
ZTE supports IMS voice and IMS Voice+Data SRVCC. The procedure is described as
follows:
Handover Control Feature Guide
ZTE Confidential Proprietary 148
1. RncSrvccSw(ULogicalRnc) is “On”.
2. The UE connects with the EUTRAN and sets up IMS voice traffic.
3. The UE reports a measurement report.
4. The EUTRAN decides an SRVCC handover to the UTRAN due to measurement
reports.
5. The EUTRAN sends a message for the PS-CS handover procedure to the CN.
6. The CN initiates the PS-CS handover to the UTRAN procedure.
1) For IMS Voice+Data combined services with inter-RAT PS handovers,
RncPsHoLteSw (ULogicalRnc) must be “On”. If SIP is required to be handed
over to the RNC according to Relocation Request message, PsSigForImsInd
(ULogicalRnc) must be “Supported”.
7. The CN informs the EUTRAN of the handover result (maybe including the result of
inter-RAT PS handovers).
8. The EURAN sends a Handover from E-UTRAN Command message to the UE after
receiving the handover result.

8.3 CSFB
Due to the continuity of voice service between UTRAN and EUTRAN, the CSFB service
can initial the PS handover from EUTRAN to UTRAN, and the corresponding CS service
can be set up in the UTRAN later.
ZTE supports CSFB, which is controlled by PSL2USWCHBYCS (ULogicalRnc), from
EUTRAN to UTRAN right now.
EUTRAN->UTRAN handover for CSFB
Procedure description: (1)The UE triggers voice traffic for originating call or terminated
call after setting up PS traffic in the EUTRAN. (2) If CS Fallback Indicator is received, PS
handover is supported and the EUTRAN will trigger a PS handover to the UTRAN. (3)
The UTRAN sets up traffic for originating call and terminated call.

8.4 Fast Return to EUTRAN
When the UMTS and EUTRAN are jointly deployed, the UE in the EUTRAN is handed
over to the UTRAN due to CSFB, SRVCC or other reasons. To make these UEs get
better service experience, the UTRAN side will return them to the EUTRAN by way of PS
HO or Redirection after the CS service is released.
The conditions of identifying CSFB UE are described as follows:
1) “CSFB Indication” is carried in the RRC Connection Request message, or
2) Neither “CSFB Indication” nor “Pre-redirection info” is carried in the RRC
Connection Request message, the time difference between RRC Connection
Request message and first RAB Assignment Request message for CS services is
not greater than GresPara7, or
3) “CSFB Information” is carried in “Source RNC to Target RNC Transparent Container”
of the Relocation Request message.
The conditions of identifying SRVCC UE are described as follows:
The UE relocated from the EUTRANincludes CS service, and RncSrvccSw is “On”.

save the frequency information of EUTRAN neighbor cells returned by the DRNC, and
the union of the saved and the frequency information of EUTRAN neighbor cells
configured for the SRNC is filled in Redirection info if the redirection conditions are met.
Currently, only the Redirection way without measurement is supported.
Support CSFB Indicator via Iur
When the SRNC sends Relocation Request to the DRNC, if the UE is identified as a
CSFB user, the SRNC needs to fill CSFB in CSFB Information of Source To Target
Transparent Container to enable the target SRNC to identify the CSFB user and apply
the function of Fast Return to EUTRAN after the relocation procedure finished.
8.5 EUTRAN Blacklist Management
In the process of an inter-RAT handover or reselection from UTRAN to EUTRAN, some
EUTRAN cells are not appropriate for the UE to camp on. Those cells, forbidden to be
reselected or measured, are informed to the UE through the way of EUTRAN blacklist, to
avoid handover or reselection failure.
Principle description: when reselection or handover is performing, if EutranNCblstSwch,
the switch of the EUTRAN neighboring blacklist management, is “1: open”, the cells in
the EUTRAN neighboring blacklist management object (UENbrBlkList:
EutranFreqBandInd/ earfcnDl/ NEutranNum/ NeutranCId/StateMode), whose StateMode
is “0” are issued to the UE through SIB19 (for non-dedicated state), whose StateMode is
“1” are issued to the UE through measurement control information (for dedicated state),
and are forbidden to be searched by UE.
The condition that IUR carries the blacklist is not considered.

8.6 Inter-RAT Handover based on EUTRAN Load
As UTRAN can acquire the load conditions in EUTRAN through the Iu interface or RIM
process, an inter-RAT handover based on EUTRAN load is taken into consideration in
order to avoid admission failure in EUTRAN because of overload in the EUTRAN system.
This function is controlled by the parameter LdBsdEutranHOInd.
Currently, the load information of Composite Available Capacity Group through RIM
process is only acquired (See “8.8 RIM” for details of RIM procedure and the load
information acquired).
Principle description: When a quality-based inter-RAT handover is triggered, if
LdBsdEutranHOInd is “support inter-RAT handover based on EUTRAN load”, the
reported EUTRAN cell‟s load information should be judged. Those EUTRAN cells, whose
downlink load (1-Composite Available Capacity Group) is equal to or greater than
EutranDlLdThrd, or uplink load (1-Composite Available Capacity Group) is equal to
or greater than EutranUlLdThrd, will be eliminated from the target cell list. After that,
if the target cell list is not empty, the first cell of that list will be selected as the target
cell in handovers.
8.7 EUTRAN Detection Supported
If the following conditions are met, the UE will detect the EUTRAN cells whose priority is
lower than the current cell, and report the results to NAS to display the coverage
conditions of EUTRAN on the terminal interface.
(1) EutraDetectionInd is “True”.
(2) The UE is in CELL_PCH/URA_PCH/IDLE state.
8.8 RIM
The function of RIM is intended to exchanging information via CN between BSS, RNC,
and eNodeB. RIM information is transferred on Iu interface through Direct Information
Transfer message.
Handover Control Feature Guide
ZTE Confidential Proprietary 158
Procedure description: The controlling BSC sends a request to the Serving BSC, asking
for some concerned information and demanding the Serving BSC to respond in the form
of report (where Controlling BSC and Serving BSC can be BSC, RNC or ENodeB). The
report form can be single report or multiple reports.
The signalling flow charts corresponding to the two kinds of report form are described as
follows:
Single Report
Controlling BSC Serving BSC
RAN-INFORMATION-REQUEST/Single Report
RAN-INFORMATION/Single Report
Multiple Report
Controlling BSC Serving BSC
RAN-INFORMATION-REQUEST/Multiple Report
RAN-INFORMATION/Multiple Report-Initial
Different from the simple procedure in single report form, which only has one time
information exchange between the Controlling BSC and Serving BSC, in multiple report
form, when the information that the Controlling BSC concerns does change or the
Serving BSC cannot provide information any more, the Serving BSC needs to inform the
Controlling BSC through the update process shown below:

Moreover, in multiple report form, if the Controlling BSC does not need the Serving BSC
to provide information any more, it should inform the Serving BSC through the
termination process shown below:

8.8.1 UTRA SI
UTRA SI is one application of RIM, mainly used for ENB gaining the UTRAN cell system
information from the UTRAN network. Then ENB will transfer these SIs to the UE
accompanying the existing message between ENB and the UE to make the UE be
reselected from LTE to UTRAN faster.
Procedure description: UtraSISwitch(URncFunction) indicates that the RNC
supports the UTRA SI function of RIM. If the ENB sends a request message
(RAN-INFORMATION-REQUEST/Multiple Report or
RAN-INFORMATION-REQUEST/Single Report) for cell UTRA SI to the RNC, the
RNC will return the SI message of its cell to EUTRAN in the response message
(RAN INFORMATION/Multiple Report Initial or RAN INFORMATION/Single Report).
Handover Control Feature Guide
ZTE Confidential Proprietary 160
8.8.2 SON Transfer
The function of SON Transfer is to exchange load information of the cell among UTRAN,
ENB, and GERAN. The target system will respond the load information of cell to source
system after receiving the RIM request message of SON Transfer Function. Currently,
only the form of single report and single cell in SON Transfer are supported.
The function is currently mainly used in obtaining the load information between UTRAN
and EUTRAN. The process is bidirectional, both of the UTRAN and EUTRAN can trigger
the process, which is explained in detail as below.
RNC acquires load information of EUTRAN cell initiatively
When the timer sonTransReqPeriod (URncFunction) expires, if LdBsdEutranHOInd is
“support inter-RAT handover based on EUTRAN load”, the RNC will send
RAN-INFORMATION-REQUEST/Single Report to the CN through the Direct Information
Transfer message to trigger the SON Transfer process. The maximum number of the
request messages sent by the RNC is sonTransReqNumThrd (URncFunction) in one
second. The load information in the response message will be saved.
ENB initializes the SON Transfer process
When the RAN-INFORMATION-REQUEST/Single Report message sent by the ENB is
analyzed from Direct Information Transfer message received from the CN, if
sonTransRespSwitch (URncFunction) is “On”, the RNC will query load information in
accordance with the requested cell ID, and then structure the
“RAN-INFORMATION/Single Report” message and feed back the message to the CN
through the Direct Information Transfer message. The maximum number of messages
accepted for requiring load information of the RNC cell is sonTransRespNumThrd
(URncFunction) in one second.
9 IMSI-based handover
The parameter BasedImsiHoInd (ULogicalRnc) indicates whether the RNC supports
IMSI-based handover.
Handover Control Feature Guide
ZTE Confidential Proprietary 161
The IMSI-based handover can limit the range of cells for allowed for handover according
to IMSI of the UE with the following principle:
While a measurement control message is not delivered before the CommonID message
is received in the signaling stage, the RNC does not know the cells authorized to the user.
Therefore, the RNC delivers a measurement control message regardless of the
authorization status of the cells.
While delivering a measurement control message after receiving the CommonID
message, the RNC queries whether the cells are authorized according to the IMSI
information carried in the CommonID message of the lu interface and also the
authorization information configured on the network side. If the SNAC list of the PLMN
carried in CommonID is empty, all the cells of that PLMN will be considered as
authorized ones. Only the authorized neighbor cells will be included in the neighbor cell
list of the measurement control message.
In the process of RAB assignment of service, a decision of whether the current service
cell is authorized is made according to the IMSI information carried in the CommonID
message and the authorization information configured in the network side.
If none of the cells in the active set is authorized
If the best cells in the active set are like the coverage neighbor cells
(ShareCover (UUtranRelation)) and are also authorized cells,
then the inter-frequency handover is performed along with service
establishment
Otherwise,
If the best cells in the active set are like the coverage GSM neighbor
cells (GsmShareCover (UGsmRelation)) and are authorized cells,
and also the current service is AMR,
then Inter-RAT directional retry is performed
Otherwise,
The RAB assignment failure procedure is performed.
Handover Control Feature Guide
ZTE Confidential Proprietary 162
Otherwise,
The service is established normally. If some of the cells in the active set are
unauthorizedcells, delete the unauthorized cells from the active set through the
active set update flow.
9.1 Querying Whether the SRNC Cell Is Authorized
According to IMSI
Figure 9-1 shows the process of querying whether a neighbor cell belonging to the SRNC
is authorized according to the IMSI information carried in the CommonID message of the
lu interface and also the authorization information configured on the network side. The
steps of the query are described as follows:
1. The MCC, MNC and other number information (10 digits at most, in the name of
ExtendInformation below) are resolved according to the IMSI carried in the
CommonID message of the lu interface. The number of digits depends on
imsiMatchedDgtNum(UImsiSnacFilter).
2. The information (MCC, MNC and ExtendInformation) resolved and also the
authorized network information imsiMatchedDgtNum(UImsiSnacFilter) configured in
the network side are used to query whether the IMSI of the UE is authorized or not.
If MCC, MNC and Extend Information of the UE does not have a configuration item
in UImsiSnacFilter, “no neighbor cell authorized” is returned. Otherwise, the MCC
(SMCC), MNC (SMNC) and SNAC that are authorized are obtained.
3. According to the relationships between MCC (SMCC), MNC (SMNC), SNAC and
LAC (USnac) and also the cell information including MCC (UUtranCellFDD), MNC
(UUtranCellFDD), LAC (UUtranCellFDD), whether the cell belongs to the MCC
(USnac), MNC (USnac, and LAC (USnac) that are already authorized is queried. If
there is much authorization information, the cell which has configuration item will be
authorized.
Handover Control Feature Guide
ZTE Confidential Proprietary 163
Note: The UImsiSnacFilter parameter can have 1000 configuration items at most and
different configuration items can have the same MNC+MNC.
Example:
1. Configuration of UImsiSnacFilter
MCC 460 460 460
MNC 99 99 99
imsiMatchedDgtNum 5 6 7
ExtendInformation [0] [1] [2]
SMCC 460 460 460
SMNC 99 99 100
SNAC 60 61 62
The IMSI of UE1 is 460991234567890, and the authorized PLMN+SNAC for UE1 are
46099+60, 46099+61, and 460100+62.
The IMSI of UE2 is 460990987654321, and the authorized PLMN+SNAC for UE1 are
460+99+60.
2. Configuration of USnac
MCC 460 460 460 460
MNC 99 99 99 100
SNAC 60 60 61 62
LAC 01 02 02 03
3. If there are three cells: the PLMN+LAC configuration of Cell1 is 46099+01, the
PLMN+LAC configuration of Cell2 is 46099+02, and the PLMN+LAC configuration
of Cell3 is 46099+03. As shown in the above table, the authorized IMSI of
CELL1/CELL2 is from 460990000000000 to 46099999999999, and the authorized
IMSI of Cell3 is from 460991200000000 to 46099129999999.So UE1 can be
authorized by CELL1/CELL2/CELL3, and UE2 can be authorized by CELL1/CELL2.

9.2 Querying Whether the DRNC Cell Is Authorized
According to IMSI
Figure 9-2 shows the process of querying whether a neighbor cell belonging the DRNC is
authorized according to the IMSI information carried in the CommonID message of lu
interface and also the authorization information configured in the network side. The steps
of the query are:
1. The MCC, MNC and other number information (10 digits at most, in the name of
ExtendInformation below) are resolved according to the IMSI carried in the
CommonID message of the lu interface. The number of digits depends on
imsiMatchedDgtNum(UImsiSnacFilter).
2. The information (MCC, MNC and ExtendInformation) resolved and also the
authorized network information imsiMatchedDigit(UImsiSnacFilter) configured in the
network side are used to query whether the IMSI of the UE is authorized or not. If
MCC, MNC and Extend Information of the UE does not have a configuration item in
UImsiSnacFilter, “no neighbor cell authorized” is returned. Otherwise, the MCC
(SMCC), MNC (SMNC) and SNAC that are authorized are obtained.

3. According to the granted MCC(SMCC), MNC(SMNC), SNAC and the DRNC
neighbor cell information including: MCC(For GSM cells, this parameter is obtained
from UExternalGsmCell. For UTRAN cells, this parameter is obtained from
UExternalUtranCellFDD), MNC (For GSM cells, this parameter is obtained from

MCC(SMCC), MNC(SMNC)and SNAC that are already authorized is queried. If
there is much authorization information, the cell that has configuration item will be
authorized.
Note: In step 3, how many SNACs are configured for the DRNC neighboring cells are
controlled by SNACNum (For GSM cells, this parameter is obtained from
UExternalGsmCell. For UTRAN cells, this parameter is obtained from
UExternalUtranCellFDD).

10 HSDPA-related special strategy
For channel changes from non-DCH to DCH in the HSDPA handover process, the target
data rate of DCH is the guaranteed bit rate of GBR traffic or the minimum rate of DRBC
for no GBR traffic(refer to ZTE UMTS DRBC Algorithm Feature Guide for details).
Handover Control Feature Guide
ZTE Confidential Proprietary 166
10.1 Overview
The cells are classified in three types according to the support capability of HSDPA
(HspaSptMeth(For serving cells, this parameter is obtained from UUtranCellFDD. For
neighboring cells, this parameter is obtained from UExternalUtranCellFDD)) after
HSDPA is introduced: (1) support HSDPA and DCH; (2) do not support HSUPA or
HSDPA; (3) support HSDPA only. The services are classified in two types: HSDPA
service and NHSDPA service. The HSDPA handover is similar to R99 handover in terms
of measurement and handover decision, except that the decisions of cell capacity during
a handover and the service type are added. For the HSDPA service, the handover is
accepted through HS-DSCH to the cells that support HSDPA and DCH and cells that
support HSDPA only as much as possible. If the HS-DSCH fails, the handover to the
cells that support HSDPA and DCH and cells that do not support HSUPA or HSDPA
through DCH is accepted. For the NHSDPA service, the handover can only be accepted
through DCH to the cells that support HSDPA and DCH and cells that do not support
HSUPA or HSDPA.
After HSDPA is introduced, the inter-RNC handover also depends on the capability of
office direction RNC to support HSDPA (RncFeatSwitchBit1) because neighbor cells
feature varying support capabilities (HspaSptMeth(UExternalUtranCellFDD)). That is,
only if both the target cell and target RNC (office direction RNC) support HSDPA, the
HS- -
handover flow cannot be originated until HS-DSCH falls back to DCH. The channel
transfer is performed along with a handover. Different channel transfer situations are
described in the following based on different handover types.
10.2 Intra-frequency Handover
The intra-frequency handover of HDSPA includes soft add/soft drop/soft replacement of
HS-DSCH associated channel, HS-DSCH service cell change, channel type change due
to different capabilities between source cell and target cell during the handover process.
The strategy of soft add/soft drop/soft replacement of HS-DSCH associated channel is
described in “strategy of intra-frequency handover”. The HS-DSCH service cell change
Handover Control Feature Guide
ZTE Confidential Proprietary 167
and channel type change are special handover strategies that make HSDPA different
from the R99 (DCH) handover. The specific principles are:
1 HS-DSCH->DCH
If the HS-DSCH is used before the handover and the link to be deleted for 1B event
triggering/radio link failure happens to be the service cell of HS-DSCH, and also the
cells in the active set do not support acceptance through HS-DSCH, a decision of
soft handover together with HS-DSCH transferring to DCH is made.
If the HS-DSCH is used before the handover and the 1C event is triggered, the cell
to be replaced is the HS-DSCH service cell and also the cells in the new active set
do not support acceptance through HS-DSCH, a decision of soft handover together
with HS-DSCH transferring to DCH is made.
If the HS-DSCH is used before the handover and the 1D event triggers
intra-frequency hard handover and the target cell does not support acceptance
through HS-DSCH, a decision of intra-frequency hard handover together with
HS-DSCH transferring to DCH is made.
2 DCH->HS-DSCH
The current service of the UE includes HSDPA and also the DCH is used before the
handover. If the 1D event triggers intra-frequency hard handover and the target cell
supports acceptance through HS-DSCH, a decision of intra-frequency hard
handover together with DCH transferring to HS-DSCH is made.
The current service of the UE includes HSDPA, the DCH is used before the
handover and also the best cell in the active set supports HSDPA. If the downlink
traffic increases to trigger the 4A event (refer to ZTE UMTS DRBC Algorithm
Feature Guide for details), a decision of handover from DCH to HS-DSCH is made.
3 HS->DSCH->HS-DSCH
If the HS-DSCH is used before the handover and the 1D event triggers
intra-frequency hard handover and the target cell supports acceptance through
HS-DSCH, a decision of intra-frequency hard handover together with HS-DSCH
service cell change is made.
Handover Control Feature Guide
ZTE Confidential Proprietary 168
If the HS-DSCH is used before the handover and the link to be deleted for 1B event
triggering/radio link failure happens to be the service cell of HS-DSCH, and also
there are cells in the active set that support acceptance through HS-DSCH, a
decision of soft handover together with HS-DSCH change is made. If the 1C/1D
event triggers a soft handover, the cell to be replaced is the HS-DSCH service cell
and also the cells in the new active set support acceptance through HS-DSCH, a
decision of soft handover together with HS-DSCH change is made.
In the above described processes, the 1D event may trigger a ping-pong handover that
leads to frequent change of service cell. To avoid this, a time threshold (T1d(UHspa)) is
configured and changes of service cell should occur at an interval longer than this
threshold.
10.3 Inter-frequency Handover
The conditions for triggering the inter-frequency handover of HDSPA are described in
“inter-frequency handover strategy”. The HS-DSCH service cell change or channel type
change always happens in the handover process. The principles are as follow:
1 HS-DSCH->DCH
The current service of the UE includes HSDPA and also the HS-DSCH is used
before the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell does not support
acceptance through HS-DSCH, a decision of inter-frequency hard handover
together with HS-DSCH transferring to DCH is made.
2 DCH->HS-DSCH
The current service of the UE includes HSDPA and also the DCH is used before the
handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell supports
acceptance through HS-DSCH, a decision of inter-frequency hard handover
together with DCH transferring to HS-DSCH is made.
3 HS-DSCH->HS-DSCH
Handover Control Feature Guide
ZTE Confidential Proprietary 169
The current service of the UE includes HSDPA and also the HS-DSCH is used
before the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell supports
acceptance through HS-DSCH, a decision of inter-frequency hard handover
together with HS-DSCH service cell change is made.
4 Handover of HS-DSCH between Iur interfaces
For the hard handover of HS-DSCH between Iur interfaces, the handover strategy is
the same as the handover inside the RNC if the target cell supports HS-DSCH. But if
the target cell does not support HS-DSCH, the HS-DSCH/DCH should fall back to
DCH/DCH first, and then the hard handover between lur interfaces and redirection
flow can be performed.
10.4 Inter-RAT Handover
Two strategies are available for handovers between HSDPA systems:
UTRAN->GSM/GERAN strategy and GSM/GERAN -> UTRAN strategy.
1 UTRAN->GSM/GERAN/LTE
The HSDPA service is included and then the same handover flow as that for
between R99 systems is performed.
2 GSM/GERAN/LTE -> UTRAN
The strategy is similar to that when a service accesses the system for the first time.
If both service and target cell support HS-DSCH/DCH, the service is established
directly on HS-DSCH/DCH, otherwise try DCH/DCH.
11 HSUPA-related special strategy
If in the handover process, the channel type changes from non-DCH to DCH, the
handover is accepted according to the target rate of DCH, that is, the guaranteed bit rate
of the current service while the handover occurs or the minimum rate of DRBC (refer to
ZTE UMTS DRBC Algorithm Feature Guide for details).
Handover Control Feature Guide
ZTE Confidential Proprietary 170
11.1 Overview
HSUPA is developed on the basis of HSDPA. An HSUPA network element (UE, RNC or
Node B) that supports HSUPA will also supports HSDPA. That is, if the E-DCH is used in
uplink, HS-DSCH is used in downlink without doubt. Therefore, HSUPA supports five
types of cells (HspaSptMeth (For serving cells, this parameter is obtained from
UUtranCellFDD. For neighboring cells, this parameter is obtained from
UExternalUtranCellFDD)): (1) cells that support HSUPA and HSDPA; (2) cells that
support HSUPA, HSDPA and DCH; (3) cells that support HSDPA and DCH; (4) cells that
support HSDPA only; (5) cells that do not support HSUPA or HSDPA. For the cells that
support HSUPA and HSDPA, the E-DCH is used in uplink and the HS-DSCH is used in
downlink. The DPCH is used as associated channel. For the cells that support HSUPA,
HSDPA and DCH, the E-DCH or DCH is used in uplink and the HS-DSCH or DCH is
used in downlink. The DPCH is used as associated channel or allocated to users who do
not use HSUPA or HSDPA.
The service types supported by HSUPA are HSPA services if they can be carried by
HSUPA or HSDPA (HSUPA and HSDPA are equivalent as far as the services are
concerned). Otherwise, they are NHSPA services. The HSPA services should be
accepted first through E-DCH and HS-DSCH in cells that support HSUPA and HSDPA,
cells that support HSDPA only, cells that support HSUPA, HSDPA and DCH and cells
that support HSDPA and DCH (HspaSptMeth (For serving cells, this parameter is
obtained from UUtranCellFDD. For neighboring cells, this parameter is obtained from
UExternalUtranCellFDD)). If E-DCH and HS-DSCH fail to accept the services, the HSPA
services should be accepted through DCH in cells that support HSUPA, HSDPA and
DCH, cells that support HSDPA and DCH or cells that do not support HSUPA or HSDPA.
The NHSPA services can only be accepted through DCH in cells that support HSUPA,
HSDPA and DCH, cells that support HSDPA and DCH or cells that do not support
HSUPA or HSDPA.
The maximum number of cells allowed in the E-DCH active set in the process of HSUPA
soft handover is 3.
After HSUPA is introduced, the inter-RNC handover also depends on the capability of
office direction RNC to support HSUPA (RncFeatSwitchBit2) because neighbor cells
Handover Control Feature Guide
ZTE Confidential Proprietary 171
feature varying support capabilities (HspaSptMeth(UExternalUtranCellFDD)). That is,
only if both the target cell and target RNC (office direction RNC) support HSUPA, the
E-DCH<->E-DCH handover can be performed. Otherwise, the DCH<->DCH handover
flow cannot be originated until the E-DCH falls back to the DCH. The channel transfer is
performed along with a handover. Different channel transfer situations are described as
follows based on different handover types.
11.2 Intra-frequency Handover
The intra-frequency handover of HSUPA includes soft add/soft drop/soft replacement of
E-DCH associated channel, E-DCH service cell change, channel type change due to
different capabilities between source cell and target cell during the handover process.
The strategy of soft add/soft drop/soft replacement of E-DCH associated channel is
described in “strategy of intra-frequency handover”. The E-DCH service cell change and
channel type change are special handover strategies that make HSUPA different from
the R99 (DCH) handover. The specific principles are:
1 HS-DSCH/E-DCH->DCH/DCH
The current service of the UE includes HSPA and also the HS-DSCH/E-DCH is
used before the handover. If the 1A event is triggered and the target cell supports
DCH/DCH instead of HS-DSCH/E-DCH, HS-DSCH/E-DCH is transferred to
DCH/DCH firstly, and then a soft handover is performed.
If the 1C event is triggered, the cell to be replaced is the HS-DSCH/E-DCH service
cell and also the target cell supports DCH/DCH instead of HS-DSCH/E-DCH,
HS-DSCH/E-DCH is transferred to DCH/DCH firstly, and then a soft handover is
performed.
If the 1D event is triggered, the best cell changes from HS-DSCH/E-DCH service
cell to a cell that does not support HS-DSCH/E-DCH, a decision of intra-frequency
hard handover with HS-DSCH/E-DCH transferring to DCH/DCH is made.
2 DCH/DCH->HS-DSCH/E-DCH
Handover Control Feature Guide
ZTE Confidential Proprietary 172
The current service of the UE includes HSPA and also the DCH/DCH is used before
the handover. If the 1D event triggers intra-frequency hard handover and the target
cell supports acceptance through HS-DSCH/E-DCH, a decision of intra-frequency
hard handover with DCH/DCH transferring to HS-DSCH/E-DCH is made.
The current service of the UE includes HSPA, the current channel type is DCH/DCH,
and also the best cell in the active set supports HSDPA. If the downlink or uplink
traffic increases to trigger the 4A event (refer to ZTE UMTS DRBC Algorithm
Feature Guide for details), a decision of handover from DCH/DCH to
HS-DSCH/E-DCH is made.
3 HS-DSCH/E-DCH->HS-DSCH/E-DCH
If the 1D event triggers intra-frequency hard handover and the target cell supports
acceptance through HS-DSCH/E-DCH, a decision of intra-frequency hard handover
together with HS-DSCH/E-DCH service cell change is made. Refer to 2.1.2
Intra-frequency Hard Handover for the scenario where the intra-frequency hard
handover is triggered.
If the link to be deleted for 1B event triggering/radio link failure happens to be the
service cell of HS-DSCH/E-DCH, and also there are cells in the active set that
support acceptance through HS-DSCH/E-DCH, a decision of soft handover
together with HS-DSCH/E-DCH service cell change is made. If the 1C/1D event
triggers soft handover, the cell to be replaced is the HS-DSCH/E-DCH service cell
and also the cells in the new active set support acceptance through
HS-DSCH/E-DCH, a decision of soft handover together with HS-DSCH/E-DCH
change is made.
4 HS-DSCH/E-DCH->HS-DSCH/DCH
The current service of the UE includes HSPA and also the HS-DSCH/E-DCH is
used before the handover. If the 1A event is triggered, and the target cell supports

HS-DSCH/E-DCH is transferred to HS-DSCH/DCH firstly, and then a soft handover
is performed.
If the 1D event is triggered, the best cell changes from HS-DSCH/E-DCH service
cell to a cell that supports HS-DSCH/DCH instead of HS-DSCH/E-DCH, a decision
of intra-frequency hard handover with HS-DSCH/E-DCH transferring to
HS-DSCH/DCH is made.
5 HS-DSCH/DCH->HS-DSCH/E-DCH
The current service of the UE includes HSPA service and also the HS-DSCH/DCH
is used before the handover. If the 1D event is triggered, the best cell changes from
HS-DSCH/DCH service cell to a cell that supports HS-DSCH/E-DCH, a decision of
intra-frequency hard handover with HS-DSCH/DCH transferring to
HS-DSCH/E-DCH is made.
11.3 Inter-frequency Handover
The conditions for triggering the inter-frequency handover of HSPA are described in
“inter-frequency handover strategy”. The HS-DSCH service cell change or channel type
change always happens in the handover process. The principles are as follow:
1 HS-DSCH/E-DCH->DCH/DCH
The current service of the UE includes HSPA and also the HS-DSCH/E-DCH is used
before the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell does not support
acceptance through HS-DSCH/E-DCH or HS-DSCH/DCH, a decision of
inter-frequency hard handover with HS-DSCH/E-DCH transferring to DCH/DCH is
made.
2 DCH/DCH->HS-DSCH/E-DCH
The current service of the UE includes HSPA and also the DCH/DCH is used before
the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell supports
acceptance through HS-DSCH/E-DCH, a decision of inter-frequency hard handover
Handover Control Feature Guide
ZTE Confidential Proprietary 174
with DCH/DCH transferring to HS-DSCH/E-DCH is made.
3 HS-DSCH/E-DCH->HS-DSCH/E-DCH
The current service of the UE includes HSPA and also the HS-DSCH/E-DCH is used
before the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell supports
acceptance through HS-DSCH/E-DCH, a decision of inter-frequency hard handover
with HS-DSCH/E-DCH service cell change is made.
4 HS-DSCH/E-DCH->HS-DSCH/DCH
The current service of the UE includes HSPA and also the HS-DSCH/E-DCH is used
before the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell supports
acceptance through HS-DSCH/DCH instead of HS-DSCH/E-DCH, a decision of
inter-frequency hard handover with HS-DSCH/E-DCH transferring to
HS-DSCH/DCH is made.
5 HS-DSCH/DCH->HS-DSCH/E-DCH
The current service of the UE includes HSPA and also the HS-DSCH/DCH is used
before the handover. If the original decision is to trigger an inter-frequency handover
(measurement-based or blind handover) and also the target cell supports
acceptance through HS-DSCH/E-DCH, a decision of inter-frequency hard handover
with HS-DSCH/DCH transferring to HS-DSCH/E-DCH is made.
6 Handover of HS-DSCH between Iur interfaces
For the hard handover of E-DCH between Iur interfaces, the handover strategy is
the same as the handover inside the RNC if the target cell supports E-DCH. But if
the target cell does not support E-DCH, the E-DCH should fall back to DCH first, and
then the hard handover between lur interfaces and redirection flow can be
performed.
Handover Control Feature Guide
ZTE Confidential Proprietary 175
11.4 Inter-RAT Handover
1 UTRAN->GSM/GERAN/LTE
The HSPA service is included, and then the same handover flow as that for between
R99 systems is performed.
2 GSM/GERAN/LTE-> UTRAN
Similar to the handover between R99 systems, if the target cell support
HS-DSCH/E-DCH, the service is established directly on HS-DSCH/E-DCH.
12 MBMS-related special strategy
After the MBMS is introduced, the cell type (MbmsSuptInd(UUtranCellFDD)) can be
defined as follows:
Cells that do not support MBMS (Not Support).
Cells that support both MBMS and non-MBMS (Support MBMS and not MBMS).
Cells that support MBMS only (Only Support MBMS).
12.1 Intra-frequency Handover
1 The soft add strategy does not consider whether the soft add cell belongs to the
service area or whether it supports the MBMS in the case of 1A/1C soft add. That is,
the strategy is similar to that for the non-MBMS case.
2 1B/1C or the link is deleted due to radio link failure:
For the MBMS service that has set up p-t-p bearer but the link is deleted, if the best
cell does not belong to MBMS service area, the best cell does not support the
MBMS service, the best cell has set up the p-t-m bearer, or the best cell is not the
convergence carrier of the service, then p-t-p RB is released.
Handover Control Feature Guide
ZTE Confidential Proprietary 176
For the MBMS service that has not set up p-t-p bearer but the MBMS service
connection already exists, the best cell belongs to MBMS service area, the best cell
supports the MBMS service, the bearer type strategy needs to set up the p-t-m
bearer and the carrier can set up the bearer of the service, then p-t-p RB is set up.
3 The principle of the type change in the bearer of the MBMS service in the active set
under the macro diversity.
Table 12-1 Table of Principle
Bearer Change Type Cell Type Principles of Change
p-t-p->p-t-m Best cell Delete the p-t-p
Non best cell No change
p-t-m ->p-t-p Best cell
Set up p-t-p: If the channel of the service is DCH,
then set up p-t-p for all cells in the active set. If the
channel of the service is HS-DSCH, then set up
p-t-p in the best cell.
Non best cell No change
To avoid ping-pong switch between p-t-p and p-t-m, a time threshold (T1d(UHspa)) is
configured and any switchover should occur at an interval longer than this threshold.
12.2 Inter-frequency Handover
When the UE reports MBMS MODIFIED REQUEST and the information of MBMS
preferred frequency request is carried,
1 If the target carrier comes with a cell with the same coverage (included: the
expected frequency layer cell includes the current working frequency cell) and the
cell belongs to the service area and supports the MBMS, and also the target cell is
able to allocate the resource of currently established dedicated bearer, then the cell
with the same coverage at the frequency layer can be taken as the target cell to
perform the hard handover.
2 If the target carrier does not come with a cell with the same coverage (included), the
neighbor cell of the current cell in the UE‟s active set includes the neighbor cell
Handover Control Feature Guide
ZTE Confidential Proprietary 177
(neighboring or being included) that is at the MBMS preferred frequency layer
corresponding to the MBMS service expected to be received and the neighbor cell
belongs to the service area and supports MBMS, then inter-frequency measurement
2A/2B/2C is started for UE. When the 2A/2B/2C event reported by the UE is
received, the cells that do not support MBMS are screened out and a proper cell is
taken for the hard handover.
No treatment is performed if the UE does not carry the information of MBMS preferred
frequency request in the MBMS MODIFIED REQUEST.

Inter-RAT Event Measurement Configuration for CPICH RSCP(GSM)
Parameter configuration
This parameter indicates the absolute threshold used when judging the quality of other
RAT configured for event 3a/3b/3c. The value range and unit of this parameter are
related to the measurement quantity of the cells of other systems. At present, the
measurement quantity can only be GSM Carrier RSSI of the GSM system, which
corresponds to the CPICH RSCP of the UMTS system. Hence, the value range and unit
of this parameter correspond to CPICH RSCP.
The larger the value is configured, the more difficult it is to report event 3a/3b/3c.
