Overview

This chapter explains the definition and classification of radio

parameters in GSM network, modification methods of radioparameters, explanation format of radio parameters, andprecautions in radio parameters adjustment.

Radio Parameters in GSM Network

GSM is an integrated system covering fields of networktechnology, digital stored program control technology, alltransmission technologies and radio technologies.

GSM consists of Network Sub System (NSS), Base Station Sub-

system (BSS) and Mobile Station (MS).

GSM system signaling structure covers MAP interface, Ainterface (between MSC and BSC), Abis interface (between BSCand BTS), Ater interface (between BSC and external TC) and Uminterface (between BTS and MS, also called air interface).

All these objects and interfaces contain large quantity ofconfiguration parameters and performance parameters, some ofwhich are determined during the development and production ofthe equipment, and most of which depend on actual need andoperation by network providers. Settings and adjustment of

latter parameters have a great impact on the operation of entire

GSM network.Radio parameters in GSM network refer to parameters related toradio devices and radio resources. These parameters have animportant impact on coverage of cells, distribution of signaling

flow and service property of network, etc. Therefore, adjustingradio parameters reasonably plays a very important part in GSMnetwork optimization.

GSM radio parameters are classified into project parameters and

resource (cell) parameters.

1. Project Parameters


12/263


2 Confidential and Proprietary Information of ZTE CORPORATION

Project parameters refer to parameters related to design,

installation, and commissioning of the project, like antennaheight, antenna direction, antenna gain, antenna download

obliquity and cable loss, etc. These parameters must be

determined during network design and are seldom changedduring the operation of the network.

2. Resource (Cell) Parameters

Resource (cell) parameters refer to parameters related toconfiguration and utilization of radio resources, which usuallytransmit on radio interface (Um) to keep the base station andmobile station consistent. Radio parameters covered in thismanual are mainly resource parameters. Radio resource

parameters in BSS contain:

GERAN subnet parameters, BSC management NE parameters,configuration set parameters;

Global resource parameters for BSC, site parameters, GERAN

external cell parameters, UTRAN external cell parameters;

Cell Parameters;

TRX parameters, power control parameters, handover controlparameters, UTRAN handover control parameters, adjacentinterference cell parameters, adjacent handover cellparameters, adjacent reselection cell parameters, adjacenthandover and reselection cell parameters, UTRAN adjacentcell handover and reselection parameters, UTRAN adjacenthandover cell parameters, UTRAN adjacent reselection cell

parameters, frequency hopping system parameters.

Methods to Modify RadioParameters

After successfully login NetNumen M31, user can perform thefollowing steps:

1. In left topology tree of NetNumen M31 main interface, right-click shortcut menu corresponding to NE agent by createdGSM, select [Start NE Agent], as shown in Figure 1.

2. Click [Start NE Agent], the system automatically starts thisNE.

3. After starting, in left topology tree of NetNumen M31 main

interface, right-click shortcut menu corresponding to NEagent by created GSM, select [NE Management

The tree in the left pane shows the objects to be created and

maintained. User can double click the nodes that itsparameters shall be modified, corresponding parameter

interface occurs in right window.

2 Under initial case, [Modify] shortcut button in

configuration management object toolbar is inactivated,which can not be modified. User shall activate this button bythe action of "Apply Mutex Right".

Note:

"Apply Mutex Right" function is to avoid multiple clients do

actions for the data, which may cause data confused and errors.

Take the data modification of primary configuration set as anexample, specific steps as follows:

i. Right-click [BSC Management NE ID], select [ApplyMutex Right] in pull-down menu, as shown in Figure 4.

this time, shortcut key is activated, and the user can

Caution:

Radio parameters in this system is modified through offlinemodification mode, that is, the modification on interface only canbe effective after the synchronization action to foreground isconducted. This article doesn't explain it more.

Some paramter values in the interface are not fully same asthose in database, with certain corresponding relationship

between them. For specific corresponding relationship see

appendix E.

Precautions in Radio ParametersAdjustment

Radio parameters adjustment, according to the type of the

problem to be solved, falls into two kinds.

First is to solve static problem, that is, to correct trafficmodel in system design by measuring actual average traffic

and signaling flow in every district and to solve commonproblems existing for long.

Second is to solve problems at a particular time like trafficoverload in some district, channel congestion due to suddenevents or random events.

For the first type, service providers must perform measurementand summarization on actual operation regularly, and thenperform appropriate adjustment on global or partial parametersand configurations. For the second type, network operatorsadjust some radio parameters at real time according to instantdata from measurement results.


20/263



Most radio parameters in GSM system are based on one cell or

one location area. It is necessary to consider whether parameteradjustment in this cell will influence other cells, especially the

adjacent one, for parameters between cells are related to each

other greatly. Otherwise, it may cause negative influence.Determine whether the problem results from equipment fault(including connections) first when it occurs in some part of thenetwork. Adjust radio parameters only when determined that theproblem does result from service.

Description

This parameter defines that BSC automaticallyindicates to MSC about the ratio of presentlyavailable channels to the total channels. Whenavailable cell resource is lower than this parameter,resource indication shall be sent to MSC about thiscell condition, which shall be configured by O&M.

The four modes of resource indication from BSC areas follows:

Automatic Mode: BSC instantly returnsBSSAP RESOURCE INDICATION messageas an acknowledgment without any

resource information, after receiving theBSSAP RESOURCE REQUEST message.BSC automatically sends BSSAPRESOURCE INDICATION message to MSC.BSC uses the periodicity IE in BSSAPRESOURCE REQUEST to determine theindication messages interval (unless the

Periodicity IE is 0 and BSC ignores 0)once O&M of BSC satisfies the Auto

condition (service threshold or the intervalbetween any two messages).

One time mode: BSC instantly returns aBSSAP RESOURCE INDICATION messagewith resource information after receivingBSSAP RESOURCE REQUEST message.BSC stops sending and waits for next

BSSAP RESOURCE REQUEST if the BSSAPRESOURCE REQUEST message does notcontain Extended Resource Indication IE.If it does, BSC will follow the rules of

Subsequent Mode element in the


56/263



message, same as Mode 4. If the previousmode is 1 or 3, BSC will adopt Mode 1 or3. Otherwise, it will adopt Mode 4.

Period mode: After BSC receives the

"BSSAP RESOURCE REQUEST" message, itwill immediately return a "BSSAPRESOURCE INDICATION" message thatcontains the resource information. Afterthat, BSC periodically sends the "BSSAPRESOURCE INDICATION" message. If"Periodicity IE" in the "BSSAP RESOURCE

REQUEST" message is not 0, then theperiod to send the message is the value of"Periodicity IE" multiplied by 100ms. IfPeriodicity IE is 0, then the message iswrong and the whole "BSSAP RESOURCE

REQUEST" message is regarded as wrong.

Stop mode: After the BSSAP RESOURCEREQUEST message is received, BSCimmediately returns a BSSAP RESOURCE

INDICATION message without anyresource information as anacknowledgement. And then, it will nolonger send the cell resource informationto MSC.
