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 success rate of handovers on themove. In addition, these KPIs indicate the capability of providing continuous services. A lowhandover success rate may lead 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 Utilization KPIs

This chapter describes the CS Resource Utilization KPIs that are used to monitor the load of hotcells and the network. These KPIs can serve as references for capacity expansion. The trafficvolume KPIs help to obtain the ratio of busy-hour traffic to idle-hour traffic, to evaluate theutilization of system resources, and to adjust charges. The equipment availability KPIs help toknow the running status of equipment, such as the running status of channels. If these KPIs arelow, equipment and transmission may be faulty.

7 CS Retainability KPIs

This chapter describes the CS Retainability KPIs that indicate the ratio of moving MSs to allMSs, 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 directly affect user satisfaction.

9 PS Data Throughput KPIs



iii

This chapter 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 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 affects user satisfaction.

11 PS Resource Utilization Rate KPIs

This chapter describes the PS Resource Utilization Rate KPIs that indicate the utilization of thenetwork resource and the busy states of services. Thus, these KPIs can be used to guide networkexpansion.

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. Thus, an increase in call drop rate directlyleads to a decrease in user 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 success rate of handovers on themove. In addition, these KPIs indicate the capability of providing continuous services. A lowhandover success rate may lead 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,thus providing better services for the MSs.

4.2 Success Rate of Radio HandoverThis 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 excludes target cellhandover failure due to congestion. Thus, Success Rate of Radio Handover is always greaterthan or equal to Handover Success Rate.

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

4.4 Internal Radio Handover Success Rate per cellCompared with Internal Handover Success Rate per cell, this counter focuses on the influenceof the Um interface on handover. It involves the procedures from sending a handover commandto handover completion, and thus reduces failures due to channel congestion.

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

4.6 External Incoming Radio Handover Success Rate per CellThis counter provides the success rate of incoming inter-BSC handovers on the Um interface.It indicates the inter-BSC handover interaction.

6 CS Resource Utilization KPIs

About This Chapter

This chapter describes the CS Resource Utilization KPIs that are used to monitor the load of hotcells and the network. These KPIs can serve as references for capacity expansion. The trafficvolume KPIs help to obtain the ratio of busy-hour traffic to idle-hour traffic, to evaluate theutilization of system resources, and to adjust charges. The equipment availability KPIs help toknow the running status of equipment, such as the running status of channels. If these KPIs arelow, equipment and transmission may be 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 UtilizabilityThis counter provides the rate of the actual traffic volume to the theoretical traffic volume.

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