What should be the values of network KPIs to be considered as degraded? Different operators have their own targets and it varies greatly depending upon vendor SLA (Service Level Agreement), Terrain (Plain/ Hilly/), Urban/Rural Area etc. However general idea is presented below:
- DCR % (Dropped Call Rate) < 1-2%
- HOSR % (Handover Success Rate) > 95-98%
- TCH Blocking % < 2% (GoS Standard)
- SDCCH Blocking % < 0.1%
- TRX Efficiency % (TCH Seizures/TCH Call Attempts X 100) > 90-99%
- IBI % (Band 4+5) < 1%
