A Study on the Hourly Behavior of Key Performance Indicators of Global System for Mobile Communications
Maria Andleeb, Syed Abbas Ali · 2015
In order to judge the quality of service (QoS) and the network performance, GSM operators use Key Performance Indicators (KPI) regarding end user perspective. KPI are derived with the help of counters which are triggered in the Base Station Controller (BSC) whenever there is an event occurrence over air interface. This paper presents the network performance of real time GSM radio frequency (RF) on the basis of KPI calculations. In this paper the hourly behavior of six major KPIs (SDR, TCH, SDCCH, DCR, HOSR, ULI) are examined by simulating separate functions of each KPI for 6 days (24*6= 144 hours). The experimental analysis shows that the Uplink (UL) interference KPI and Handover Success Rate (HOSR) KPI are perform better as compared to the other KPIs.
