About This Chapter

The following KPIs are GSM Service KPIs.

2.1 CS Accessibility KPIsThis describes the CS accessibility KPIs that mainly indicate the call success rate when an MSaccesses the network. Low accessibility KPIs directly lead to low user satisfaction.

2.2 CS Mobility KPIsThis describes the CS Mobility KPIs that indicate the success rate of handovers on the move. Inaddition, these KPIs indicate the capability of providing continuous services. A low handoversuccess rate may lead to a high call drop rate.

2.3 CS Receive Quality KPIsThis describes the CS Receive Quality KPIs that indicate the mean receive quality rank on theTCH.

2.4 CS Resource Utilization KPIsThis describes the CS Resource Utilization KPIs that are used to monitor the load of hot cellsand the network. These KPIs can serve as references for capacity expansion. The traffic volumeKPIs help to obtain the ratio of busy-hour traffic to idle-hour traffic, to evaluate the utilizationof system resources, and to adjust charges. The equipment availability KPIs help to know therunning status of equipment, such as the running status of channels. If these KPIs are low,equipment and transmission may be faulty.

2.5 CS Retainability KPIsThis describes the CS Retainability KPIs that indicate the ratio of moving MSs to all MSs, themoving frequency. In addition, these KPIs indicate the capability of providing continuousservices. A low success rate leads to low user satisfaction.

2.6 PS Accessibility KPIsThis describes the PS Accessibility KPIs that indicate whether MSs can easily access cells. PoorPS Accessibility KPIs directly affect user satisfaction.

2.7 PS Data Throughput KPIsThis describes the PS Data Throughput Rate KPIs. They involve the performance factorsassociated with the terminals, the radio access network, and the core network. Now, the mainperformance problem is concerned with the radio access network. Therefore, these KPIs indicate

SingleRANKPI Reference 2 GSM Service KPI

the end-to-end service data link bearing capability of the GPRS network, which are directlyrelated to user satisfaction.

2.8 PS delay KPIsThis describes the PS Delay KPIs that indicate the service response speed of the network. Longdelay affects user satisfaction.

2.9 PS Resource Utilization Rate KPIsThis describes the PS Resource Utilization Rate KPIs that indicate the utilization of the networkresource and the busy states of services. Thus, these KPIs can be used to guide networkexpansion.

2.10 PS Retainability KPIsThis describes the PS Retainability KPIs that mainly involves the uplink and downlink TBF calldrop rates. These KPIs indicate the capability of providing continuous services by the networkand are directly related to user satisfaction. Thus, an increase in call drop rate directly leads toa decrease in user satisfaction.

2.11 PS Transmission Performance KPIsThis describes the PS Transmission Performance KPIs that indicates the quality of radiotransmission links in a cell. If the RLC data block retransmission rate in a cell is high, the qualityof the radio transmission links in the cell is poor. Therefore, take corresponding measures, suchas RF optimization.

3 UMTS Service KPI

About This Chapter

The following KPIs are UMTS Service KPIs.

3.1 AccessibilityAccessibility is the ability of a user to obtain the requested service from the system. RRCconnection and RAB setup are the main procedures of accessibility. These items can becalculated per cell and per RNC, and the RNC level KPI is calculated by aggregating all the cellcounters that belong to the RNC.

3.2 AvailabilityAvailability KPIs mainly indicate the utilization for several kinds of of network resources suchas Radio,bandwith or CPU load.

3.3 CoverageCoverage KPIs are uesed for monitoring cell Interference status and Soft Handover Gain in aRNC or a cluster.

3.4 MobilityMobility KPIs are used to monitoring the successful ratio for several kinds of of handoverfeatures or service mode changing in difference scenarios.

3.5 RetainabilityRetainability is defined as the ability of a user to retain its requested service for the desiredduration once connected. These items can be calculated per cell or per RNC. The RNC levelKPIs can be calculated by aggregating all the cell counters and Iur counters. If RNC switch onpreemption feature, the release due to preemption is statistic into call drop with abnormal release.

3.6 Service IntegrityService Integrity KPIs mainly indicated the service capabilities for PS/HSPA throughput onbusy hour in each cell and the service UL Average BLER for evaluating the UL BLER value ofservices in each cell.

3.7 TrafficTraffic KPIs are used to evaluate the circulated traffic such as CS Equivalent Erlang,PSTraffic,Mean UE number for several kinds of of services in a RNC or cluster.

These items can becalculated per cell and per RNC, and the RNC level KPI is calculated by aggregating all the cellcounters that belong to the RNC.

3.1.1 IU Paging Success RatioThis KPI can be used to evaluate the successful responses to the paging from the Core Network(CN) in one RNC. However, the lower paging success ratio does not always mean the lowerpaging response because paging may be occurred due to the unnecessary paging messages fromthe CN. Therefore, the terminal radio access success ratio and the CN's paging strategy shouldbe analyzed for further confirmation.

3.1.2 Radio Access Success Ratio(RNC)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 isusually 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 usedto evaluate the radio access success ratio in a RNC, and the access failures caused by the SCCPcongestion are not considered in this call setup procedure.
