The minimum KPI’s and target i use are:
Routes: grade of Service (GOS)
– Route GOS (MSC-MSC, MSC-BSC)=max 1%
– Roue GOS (transit level)=max. 1%
Congestion:
– Route congestion (transit level)=max. 2%
– Route congestion (MSC-MSC, MSC-BSC)= max.5%
Answer Seizure Ratio (ASR):
– Route ASR= min. 50%
Signalling:
