5G standalone - what is KPI for retainability?

Hi,

Need KPI formula for 5G Standalone retainability , since there is only single flow only QoS flow?

It is going to be 5QI (6/7/8/9) abnormal releases from gNB and AMF are your total drops

So, abnormal releases from gNB + AMF for all 5QI divided to total releases + abnormal releases gNB + AMF

how AMF comes to picture … its only data flow call

abnormal releases due to gNB and AMF related…Like LTE (enb and mme related abnormal releases)
