Organization1 Changes in BSS KPI Reference

This describes the changes of BSS KPI Reference.

2 Introduction to KPI

This describes the KPI, which is used to monitor the network performance and detect networkproblems.

3 CS Accessibility KPIs

This describes the CS accessibility KPIs that mainly indicate the call success rate when a MSaccesses the network. Low accessibility KPIs directly lead to low user satisfaction.

4 CS Retainability KPIs

This 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.

5 CS Mobility KPIs

This describes the CS Retainability KPIs that indicate the success rate of handovers on the move.In addition, these KPIs indicate the capability of providing continuous services. A low handoversuccess rate may lead to a high call drop rate.

6 CS Resource Utilization KPIs

This 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.

7 CS CPU Usage KPI

This describes the CS CPU Usage KPI that indicates the mean ratio of the busy time of the CPUin a Granularity Period.

8 CS Receive Quality KPIs

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

Issue 02 (2010-01-30)

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

10 PS Retainability KPIs

This describes the PS Retainability KPIs that mainly involve 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.

11 PS Transmission Performance KPIs

This describes thePS 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.

12 PS Resource Utilization Rate KPIs

This 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.

13 PS Throughput KPIs

This describes the PS Throughput KPIs that are used to monitor the load of hot cells and thenetwork and to obtain service models. These KPIs can serve as references for capacity expansion.The PS Throughput KPIs help to obtain the busy-hour PS traffic and the idle-hour PS traffic, toevaluate the utilization of system resources, and to facilitate service assessment of carriers.

14 PS Delay KPIs

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

15 PS Data Throughput Rate KPIs

This 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 are directlyrelated to user satisfaction.

2 Introduction to KPI

This describes the KPI, which is used to monitor the network performance and detect networkproblems.

KPI AttributesEach KPI has the following attributes:

l Measurement object: indicates the measurement scope of a KPI, such as BSC level, PCUlevel, or cell level.

l Measurement set: describes the signaling or algorithm of collecting a KPI, such as callaccess and TBF establishment.

l Measurement service: indicates the service type of a KPI, such as CS service or PS service.

Measurement SetFigure 2-1 shows the measurement set of the CS domain performance counters. Callmeasurement and channel measurement are very important. Most of performance counters aredistributed in the two measurement sets.

l Call measurement: refers to the measurement of call services in a BSC.

l Channel measurement: refers to the measurement of various counters related to channels.

The CS KPIs can be categorized into the following:

l Accessibility KPIs

l Retainability KPIs

l Mobility KPIs

l Resource Utilization KPIs

l CPU Usage KPIs

l Receive Quality KPIs

The PS KPIs can be categorized into the following:

Collection of KPIsCS KPIs per cell and KPIs per BSC can be viewed and analyzed on the M2000. KPIs can beexported from the M2000 as .csv, .xls, .html, or .txt files. In addition, CS KPIs per BSC can beviewed and analyzed through the BSC6000 intelligent report system. KPIs can be exported fromthe BSC6000 intelligent report system as .csv, .xls, .html, or .txt files.

PS KPIs, such as Throughput KPIs, Transmission KPIs, Accessibility KPIs, Resource utilizationKPIs, and Retainability KPIs can be viewed and analyzed on the M2000. KPIs can be exportedfrom the M2000 as .csv, .xls, .html, or .txt files.

In addition, PS KPIs can be set and queried through the OMC traffic console.

End-to-end performance KPIs can be queried through Drive Test and Call Quality Test.

NOTE

The measurement object has time spans, and KPIs are collected on schedule; therefore, KPI collection may spandifferent periods.

If the KPIs reflect the actual status of the measurement object at a moment, the KPI collection inevitably spansdifferent periods.

6 CS Resource Utilization KPIs

About This Chapter

This 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.

10 PS Retainability KPIs

About This Chapter

This describes the PS Retainability KPIs that mainly involve 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.

14.1 PING Delay

Table 14-1 PING Delay

Counter PING Delay

Description The PING delay is the difference between the time when the MS sendsan ICMP packet of the Return Request type and the time when thereceiving end responds with an ICMP packet of the ReturnAcknowledgment type. Two types of PING delay are available: initialPING delay and consecutive PING delay.l Initial PING delay

If the interval between two consecutive PING operations is longerthan 9000 ms, the MS enters the Packet Idle Mode. If the PINGoperation is re-initiated, the TBF established on the CCCH is used.Therefore, the initial PING delay is longer.

l Consecutive PING delayIf the interval between two consecutive PING operations is shorterthan 500 ms, the PCU uses the uplink delay release or downlink delayrelease policy. This avoids the TBF establishment for the followingPING operations or the TBF re-establishment on the PACCH. ThisPING delay is relatively shorter.

The GPRS throughput focuses mainly on thethroughput at the RLC/MAC layer and the throughput at the applicationlayer. The test of the throughput at the RLC/MAC layer is difficult.Therefore, the throughput we discuss generally refers to the throughputat the application layer. The throughput at the RLC/MAC layer isgenerally higher than that at the application layer.
