3 Availability

Availability KPIs mainly indicate the utilization for several several kinds of of network resources

such as Radio,bandwith or CPU load.

4 Coverage

Coverage KPIs are uesed for monitoring cell Interference status and Soft Handover Gain in a

RNC or a cluster.

5 Mobility

Mobility KPIs are used to monitoring the successful ratio for several kinds of of handover features or service mode changing in difference scenarios.

6 Retainability

Retainability is defined as the ability of a user to retain its requested service for the desired

duration once connected. These items can be calculated per cell and per RNC. The RNC level

KPIs can be calculated by aggregating all the cell counters and Iur counters.

7 Service Integrity

Service Integrity KPIs mainly indicated the service capabilities for PS/HSPA throughput on

busy hour in each cell and the service UL Average BLER for evaluating the UL BLER value of

services in each cell.

8 Traffic

Traffic KPIs are used to evaluate the circulated traffic such as CS Equivalent Erlang,PS

Traffic,Mean UE number for several kinds of of services in a RNC or cluster.

2 Accessibility

About This Chapter

Accessibility is the ability of a user to obtain the requested service from the system. RRC

connection and RAB setup are the main procedures of accessibility. These items can be

calculated per cell and per RNC, and the RNC level KPI is calculated by aggregating all the cell

counters that belong to the RNC.

2.1 Radio Access Success Ratio

A complete call setup procedure contains the RRC connection, RAB setup, and Direct Transfer.

Generally only the RRC connection and the RAB setup can be observed from RAN and it is

usually assumed that no error occurs when RAN handles the direct transfer messages. That is,

the authentication procedure is considered to be successfully performed. This KPI can be used

to evaluate the radio access success ratio in one RNC or a cluster, and the access failures caused

by the SCCP congestion are not considered in this call setup procedure.

2.2 RRC Setu p Success Ratio (other)

The RRC setup procedure is trigged by different reasons which are divided into two classes:

related service and other reasons. This KPI can be used to evaluate the RRC setup success ratio

excluding the service causes in one RNC or a cluster.

2.3 RRC Setup Success Ratio (service)



for service causes in one RNC or a cluster.

2.4 AMR RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of the AMR service in one RNC

or a cluster. This KPI cannot be used to evaluate the AMR call setup success ratio unless the

related RRC procedures of all AMR services are successful.

2.5 VP RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of the VP service in one RNC or

a cluster. This KPI cannot be used to evaluate the VP call setup success ratio unless the related

RRC procedures of the VP service are successful.

2.6 CS RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of all CS services in one RNC or a cluster.

2.7 PS RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of all PS services in one RNC or

a cluster.

2.8 HSDPA RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of the PS service carried by HSDPAin a RNC or a cluster.

2.9 HSUPA RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of the HSUPA service in a RNC

or a cluster.

2.10 E-FACH RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of the E-FACH service in a RNC

or a cluster.

2.11 CS over HSPA RAB Setup Success Ratio

This KPI can be used to evaluate the RAB setup success ratio of the CS over HSPA service in

a RNC or a cluster.

2.12 PTM Channel Setup Success Ratio

This KPI can be used to evaluate the channel setup success rate of MBMS service in PTM mode.

2.13 PTP Channel Setup Success Ratio

This KPI can be used to evaluate the channel setup success rate of MBMS service in PTP mode.

About This Chapter

Traffic KPIs are used to evaluate the circulated traffic such as CS Equivalent Erlang,PS

Traffic,Mean UE number for several kinds of of services in a RNC or cluster.

8.1 PS UL Throughput

This KPI can be used to evaluate the UL throughput of all PS services of one RNC.

8.2 PS DL Throughput

This KPI can be used to evaluate the DLthroughput of all PS services of one RNC.

8.3 DL Traffic of Typical Radio BearersThis grouped KPIs can be used to evaluate the average DL traffic of typical radio bearers at busy

hour in one R NC, which means the traffics from different services are different although they

are in the same unit.
