RF optimization issues in GSM networks
Sh. O. Seytnazarov · 2010
All GSM operators use Key Performance Indicators (KPIs) to judge their network performance and evaluate the Quality of Service (QoS) regarding end user perspective. All the events being occurred over air interface are triggering different counters in the Base Station Controller (BSC). In this paper GSM network RF performance evaluation is presented based on some major KPIs such as Call set up success rate (CSSR), Call Drop Rate (CDR), Handover Success Rate (HSR) and Traffic channel (TCH) congestion rate.
