Organization1 Changes in the GBSS KPI Reference

This chapter describes the changes made in the GBSS KPI Reference.

2 CS Accessibility KPIs

This chapter describes the CS accessibility KPIs that mainly indicate the call success rate whenan MS accesses the network. Low accessibility KPIs directly lead to low user satisfaction.

3 CS CPU Usage KPI

This chapter describes the CS CPU usage KPI that indicates the mean ratio of the busy time ofthe CPU in a granularity period.

4 CS Mobility KPIs

This chapter describes the CS mobility KPIs that indicate the handover success rate on the move.In addition, these KPIs indicate the capability of providing continuous services. A low handoversuccess rate leads to a high call drop rate.

5 CS Receive Quality KPIs

This chapter describes the CS receive quality KPIs that indicate the mean receive quality rankon the TCH.

6 CS Resource Usage KPIs

This chapter describes the CS resource Uusage KPIs that are used to monitor the load of hotspots and the network. These KPIs can serve as references for capacity expansion. The trafficvolume KPIs help operators obtain the ratio of traffic during peak hours to traffic during off-peak hours, to evaluate the system resource usage, and to adjust charges. The equipmentavailability KPIs help operators learn about the running status of equipment, such as the runningstatus of channels. If these KPIs are low, equipment and transmission are faulty.

7 CS Retainability KPIs

This chapter describes the CS retainability KPIs that indicate the ratio of moving MSs to all MSsas well as the moving frequency. In addition, these KPIs indicate the capability of providingcontinuous services. A low success rate leads to low user satisfaction.

8 PS Accessibility KPIs

This chapter describes the PS accessibility KPIs that indicate whether MSs can easily accesscells. Poor PS accessibility KPIs decrease user satisfaction.

9 PS Data Throughput KPIs

This chapter describes the PS data throughput rate KPIs. They involve the performance factorsassociated with the MSs, the radio access network, and the core network. Now, the mainperformance problem is concerned with the radio access network. Therefore, these KPIs indicatethe end-to-end service data link bearing capability of the GPRS network, which is directly relatedto user satisfaction.

10 PS Delay KPIs

This chapter describes the PS delay KPIs that indicate the service response speed of the network.Long delay decreases user satisfaction.

11 PS Resource Usage KPIs



iii

This chapter describes the PS resource usage rate KPIs that indicate the network resource usageand the busy states of services. Therefore, these KPIs can be used to guide network expansion.

12 PS Retainability KPIs

This chapter describes the PS retainability KPIs that mainly involve the uplink and downlinkTBF call drop rates. These KPIs indicate the capability of providing continuous services by thenetwork and are directly related to user satisfaction. Therefore, a high call drop rate decreasesuser satisfaction.

13 PS Transmission Performance KPIs

This chapter describes the PS transmission performance KPIs that indicate 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.

4 CS Mobility KPIs

About This Chapter

This chapter describes the CS mobility KPIs that indicate the handover success rate on the move.In addition, these KPIs indicate the capability of providing continuous services. A low handoversuccess rate leads to a high call drop rate.

4.1 Handover Success RateThis counter provides the rate of the total number of successful handovers due to any cause tothe total number of handover requests due to any cause. The purpose of handover is to ensurethe call continuity, improve the speech quality, and reduce the cross interference in the network,providing better services for the MSs.

4.2 Um-Interface Handover Success RateThis counter provides the handover success rate on the Um interface after a handover commandis sent and before the handover is complete. Statistics taken by this item exclude target cellhandover failure due to congestion. Therefore, the value of this counter is always greater thanor equal to the value of Handover Success Rate.

4.3 Intra-BSC Handover Success RateThis counter provides the intra-BSC handover success rate, including the intra-BSC intra-cellhandovers and intra-BSC inter-cell handovers. It indicates intra-BSC handover, and reduces theinfluence of other BSCs.

4.4 Um-Interface Intra-BSC Handover Success RateCompared with Intra-BSC Handover Success Rate, this counter focuses on the influence of theUm interface on handover. It involves the procedures from sending a handover command tohandover completion, and therefore reduces failures due to channel congestion.

4.5 Incoming Inter-BSC Handover Success RateThis counter provides the success rate of incoming inter-BSC handovers. It indicates the inter-BSC handover interaction.

4.6 Um-Interface Incoming Inter-BSC Handover Success RateThis counter provides the success rate of incoming inter-BSC handovers on the Um interface.It indicates the inter-BSC handover interaction.

6 CS Resource Usage KPIs

About This Chapter

This chapter describes the CS resource Uusage KPIs that are used to monitor the load of hotspots and the network. These KPIs can serve as references for capacity expansion. The trafficvolume KPIs help operators obtain the ratio of traffic during peak hours to traffic during off-peak hours, to evaluate the system resource usage, and to adjust charges. The equipmentavailability KPIs help operators learn about the running status of equipment, such as the runningstatus of channels. If these KPIs are low, equipment and transmission are faulty.

6.1 Traffic Volume on SDCCHThis counter provides the ratio of the duration for which the MS occupies the signaling channelto the granularity period. The signaling channels include the SDCCHs and the TCHs used forsignaling channels.

6.2 Traffic Volume on TCHThis counter provides the frequency of seizing the TCHs, that is, the actual length of activatedTCHs.

6.3 TCHH Traffic VolumeThis counter provides the traffic volume on the TCHs of all the cells under the control of theBSC, excluding the traffic volume in the very early assignment.

6.4 TCH AvailabilityThis counter provides the rate of available TCHs to configured TCHs.

6.5 TCH Resource UsageThis counter provides the rate of the actual traffic volume to the theoretical traffic volume.

6.6 TRX UsageThis counter provides the rate of available TRXs in a cell to TRXs configured in the cell.

6.7 SDCCH AvailabilityThis counter provides the rate of available SDCCHs to configured SDCCHs.

About This Chapter

This chapter describes the CS retainability KPIs that indicate the ratio of moving MSs to all MSsas well as the moving frequency. In addition, these KPIs indicate the capability of providingcontinuous services. A low success rate leads to low user satisfaction.

7.2 Call Drop Rate on TCH per Cell (Excluding Handover)This counter provides the rate of TCH call drops to successful TCH seizures after the BSCassigns the TCH to an MS (excluding handovers) in a BSC.

7.3 Traffic Call Drop Rate per CellThis counter provides the rate of traffic volume to call drops. It indicates the average interval atwhich a call drop occurs in a cell.

7.4 Radio Drop Rate of TCHThis counter provides the rate of call drops due to faults in the Um interface to total successfulTCH seizures.

Notes 1. The upload test is different from the download test. This counter isappraised in the mode of download test:2. The Service Interruption Delay for Cell Reselection (ms) is appraisedthrough the Um interface on some networks. This counter is defined asfollows: the interval between the time when the Cell Reselection messageis displayed with the MA test tool, such as TEMS, and the time when theMS initiates the Channel Request message in a new cell. The signalingshows the interval which is measured manually.3. The Service Interruption Delay for Cell Reselection (ms) is impactedby the following factors: Whether the NACC and NC2 modes are enabled;whether the 2G/3G inter-RAT cell reselection is performed; whether thecross-RA reselection is performed.
