5 Key Performance Indicators
About This Chapter
This topic describes the key performance indicators (KPIs). According to indicated
performances, KPIs are classified into CS KPIs and PS KPIs.
5.1 Introduction to Key Performance Indicators
This topic gives the introduction to KPIs that reflect network performance. Through monitoring
the variations of performance counters, you can promptly find out network performance
problems.
5.2 CS Accessibility KPIs
This topic describes the CS Accessibility KPIs that mainly indicate the call success rate when aMS accesses the network. Low Accessibility KPIs directly leads to low user satisfaction.
5.3 CS Retainability KPIs
This topic describes the CS Retainability KPIs that indicate the ratio of moving MSs to all MSs,
the moving fr equency, and the success rate of handovers on the move. In addition, these KPIs
indicate the capability of providing continuous services. A low handover success rate may lead
to a high call drop rate. A low success rate leads to low user satisfaction.
5.4 CS Resource Utilization KPIs
This topic describes the CS Resource Utilization KPIs that are used to monitor the load of hot
spot cells and the network. These KPIs can serve as references for capacity expansion. The traffic
volume KPIs help to obtain the ratio of busy-hour traffic to idle-hour traffic, to evaluate the
utilization of system resources, and to adjust charges. The equipment availability KPIs help to
know the running status of equipment, such as the running status of channels. If these KPIs are
low, equipment and transmission may be faulty.
5.5 PS Throughput KPIs
This topic describes the PS Throughput KPIs that are used to monitor the load of hot spot cells
and the network 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, to evaluate the utilization of system resources, and to facilitate service assessment of
carriers.
5.6 PS Transmission KPIs
This topic describes the PS Transmission KPIs that indicate the quality of radio transmissionlinks in a cell. If the RLC data block retransmission rate in a cell is high, the quality of the radio

transmission links in the cell is poor. Therefore, you need to take corresponding measures, such
as RF optimization.
5.7 PS Accessibility KPIs
This topic describes the PS Accessibility KPIs that indicate whether MSs can easily access cells.
Poor PS Accessibility KPIs directly affect user satisfaction.
5.8 PS Resource Utilization KPIs
This topic describes the PS Resource Utilization KPIs that indicate the utilization of the network
resource and the busy states of services. Thus, these KPIs can be used to guide network
expansion.
5.9 PS Retainability KPIs
This topic describes the PS Retainability KPIs that mainly involve the uplink and downlink TBF
call drop rates. These KPIs indicate the capability of providing continuous services by the
network and are directly related to user satisfaction. Thus, an increase in call drop rate directly
leads to a decrease in user satisfaction.
5.10 PS End-to-End Delay KPIsThis topic describes the PS End-to-End Delay KPIs that indicate the service response speed of
the network. Long delay affects user satisfaction.
5.11 PS End-to-End Quality KPIs
This topic describes the PS end-to-end quality KPIs. They involve the performance factors of
terminals, the radio access network, and the core network. Now, the main performance
bottleneck comes from 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 user
satisfaction.

5.1 Introduction to Key Performance Indicators
This topic gives the introduction to KPIs that reflect network performance. Through monitoring
the variations of performance counters, you can promptly find out network performance
problems.
Property
Each counter has the following three properties:
l Measurement object: indicates the measurement range, such as the BSC, the PCU, or a cell.
l Measurement family: indicates the signaling procedure or algorithm, such as call access
and TBF setup.
l Measured service: indicates the measured service type, such as CS and PS services.
Measurement Family
Figure 5-1 shows the measurement family of the CS domain performance counters. Call
measurement and channel measurement are very important. Most of performance counters are
distributed in the two measurement families.
l Call Measurement per BSC refers to the measurement of call services in a BSC.
l Channel Measurement per BSC refers to the measurement of various counters related to
channels.

Classification of KPIs by Measurement Mode
According to the indicated performance, KPIs that are commonly used in routine monitoring
are classified as follows:
The CS KPIs can be categorized into:
l Accessibility KPIs
l Retainability KPIs
l Resource Utilization
The PS KPIs can be categorized into:
l Throughput KPIs
l Transmission KPIs
l Accessibility KPIs
l Resource Utilization
l Retainability KPIs
l End-to-End Quality KPIs

Collection of KPIs
CS KPIs can be viewed and analyzed on the M2000. In addition, KPIs can be exported from the
M2000 as a .csv, .xml, or .txt file. CS KPIs can be viewed and analyzed through the BSC6000
intelligent report system. In addition, KPIs can be exported from the system as a .xml, .xls,

5.6 PS Transmission KPIs
This topic describes the PS Transmission KPIs that indicate the quality of radio transmissionlinks in a cell. If the RLC data block retransmission rate in a cell is high, the quality of the radio
transmission links in the cell is poor. Therefore, you need to take corresponding measures, such
as RF optimization.
