About This Document

PurposeThis document describes the RAN KPI and the counters used to calculate the KPI. Originally,the KPI was described based on the commercial network management and radio networkoptimization. However, the KPI description is updated from time to time based on therequirements of customers.

Product VersionsThe following table lists the product versions included in this document.

Product Name Product Version

Intended AudienceThis document is intended for:

l Network planning engineersl Field engineersl System engineers

Organization1 Changes in the RAN KPI Reference

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

2 Accessibility

Accessibility is the ability of a user to obtain the requested service from the system. RRCconnection and RAB setup are the main procedures of accessibility.

RANKPI Reference About This Document


ii

3 Availability

Availability KPIs mainly indicate the utilization for several kinds of network resources such asRadio, bandwidth or CPU Load.

4 Coverage

Coverage KPIs are used for monitoring cell Interference status and Soft Handover Gain in anRNC or a cluster.

5 Mobility

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

6 Retainability

Retainability is defined as the ability of a user to retain its requested service for the requiredduration once connected. The RNC level KPIs can be calculated by aggregating all the cellcounters and Iur counters.

7 Service Integrity

Service Integrity KPIs mainly indicate the service capabilities for PS/HSPA throughput duringbusy hours in each cell and the service UL Average BLER for evaluating the UL BLER valueof services in each cell.

8 Traffic

Traffic-related KPIs are used to check the circulated traffic such as CS Equivalent Erlang, PSTraffic, and Mean UE number for various kinds of services in an RNC or a Cluster.

It considered the radio link quantity during thesoft handover.In the RNC Soft handover ratio, count the mean number of UEs with differentquantity of radio links for RNC from A1 to F1. The RNC periodically samplesof the number of UEs with corresponding radio links in a measurement period.At the end of the measurement period, the RNC divides the accumulatednumber by the sampling times to obtain the soft handover overhead.The Cell level KPI is only available for cells in a cluster.

counted twice respectively in VS.DCCC.D2P.Succ(orVS.DCCC.Succ.F2P) and VS.RAB.NormRel.PS.

The same reason as VS.RAB.AbnormRel.PS.PCH.The measurement object of the counters in Sum{*} is the cell, the RNC levelKPI can be calculated approximately by aggregating all the cell level countersin the SRNC.

Table 8-9 Number of HSDPA MIMO Users

Name Mean Number of HSDPA MIMO Users

Description This KPI provides the average number of HSDPA MIMO UEs in an HSDPAcell.The number of HSDPA MIMO UEs is sampled periodically in the HSDPAcells. At the end of the measurement period, the RNC divides the accumulatedtime weight value of each sampling point by the sampling period, thusobtaining the average number of MIMO UEs in the HSDPA cell.

Description This KPI provides the average number of HSDPA MIMO64QAM UEs in anHSDPA cell.The system periodically samples the number of MIMO+64QAM UEs. At theend of the measurement period, by dividing the accumulated value of sampledata in the period by the number of samples, the average number of MIMO+64QAM UEs in the measurement period is obtained.

Table 8-12 Number of MBMS Users

Name Mean Number of MBMS Users

Description The previous measurement counter provides the mean number of UEs thatsubscribes to MBMS channel in PTP mode in a cell.If the MBMS channel is in PTP mode, the number of cell_MBMS UEs isreported when a connected UE orders or releases the program in the cell.When the MBMS channel switches from PTM to PTP, the number of UEsthat have currently ordered the program in the cell is reported. When theMBMS channel switches from PTP to PTM, the number of UEs that haveordered the program in PTP mode is reported as 0.

Table 8-13 HSDPA RLC Traffic Volume

Name HSDPA RLC Traffic Volume

Description This KPI provides the total downlink bytes of all the HSDPA MAC-d flowsin a cell.When the data is transmitted to an HSDPA serving cell, the RNC measuresthe number of total bytes sent in the downlink (including data of all types ofservices) at the RLC layer for the MAC-d flow in the cell. The RLC headerand the retransmitted data are excluded.
