Key Performance Indicators
This chapter covers the following topics;
y Network Performance Measurement
Network PerformanceMeasurementIn GSM, performance of the network can be analyzed through KPIs. KPIsare the specific counters, which represent statistics of overall performanceof the network. Network performance judgment such as about resource
status, service status or channel quality is possible through these statistics.Statistics comes from the basic measurement of the Control System.Degradation in the performance of the specific cells can be identified inOMCR by analyzing the KPIs. In this way specific problem can be resolvedaccordingly.
Table 4 lists the entire Key Performance Measurement Counters.

BTS Measurement
This chapter covers the following topics:
y Power Control Measurement
y TRX Service Measurement
y Paging Messages Measurement
y TRX Basic Measurement
y TRX Power & Temperature Measurement
Power Control MeasurementPower Control enables the mobile station and/or the BTS to increase ordecrease the transmission power on a per-radio link basis.
Power Control is separately performed for the uplink and downlink. In bothcases the BSC is responsible for initiating Power Control; the mobilestation and the BTS adopt transmit power according to the BSC PowerControl commands.
Two modes of power control are:
y Normal power control
y Rapid power control
Amplitude of power adjustment in rapid control is greater than normalpower control.
BTS regularly samples the power of MS and BTS itself, to obtain average
power. BTS regularly reports the average power to BSC through PC TESTRPT message, for power control. Measurement report helps in analyzing
the coverage quality as well as the effect and rate of power control.
