Organization1 Introduction to KPI

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

2 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.

3 CS Retainability KPIs

This describes the CS Retainability KPIs that indicate the ratio of moving MSs to all MSs, themoving frequency, and the success rate of handovers on the move. In addition, these KPIsindicate the capability of providing continuous services. A low handover success rate may leadto a high call drop rate. A low success rate leads to low user satisfaction.

4 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.

5 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.

6 PS Transmission KPIs

This describes the PS Transmission KPIs that indicate the quality of radio transmission links ina cell. If the RLC data block retransmission rate in a cell is high, the quality of the radiotransmission links in the cell is poor. Therefore, take corresponding measures, such as RFoptimization.

7 PS Accessibility KPIs

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

8 PS Resource Utilization KPIs

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

9 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.

10 PS End-to-End Delay KPIs

This describes the PS End-to-End Delay KPIs that indicate the service response speed of thenetwork. Long delay affects user satisfaction.

11 PS End-to-End Quality KPIs

This describes the PS end-to-end quality KPIs. They involve the performance factors associatedwith the terminals, the radio access network, and the core network. Now, the main performanceproblem is concerned with the radio access network. Therefore, these KPIs indicate the end-to-end service data link bearing capability of the GPRS network, which are directly related to usersatisfaction.

1 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 1-1 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.

Classification of KPIsKPIs that are commonly used in routine monitoring can be classified according to the indicatedperformance.

The CS KPIs can be categorized into the following:

l Accessibility KPIsl Retainability KPIsl Resource Utilization KPIs

The PS KPIs can be categorized into the following:

l Throughput KPIsl Transmission KPIsl Accessibility KPIsl Resource utilization KPIsl Retainability KPIsl End-to-End Delay KPIsl End-to-End Quality KPIs

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.

3 CS Retainability KPIs

About This Chapter

This describes the CS Retainability KPIs that indicate the ratio of moving MSs to all MSs, themoving frequency, and the success rate of handovers on the move. In addition, these KPIsindicate the capability of providing continuous services. A low handover success rate may leadto a high call drop rate. A low success rate leads to low user satisfaction.

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.

10.1 PING Delay

Table 10-1 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.
