A.8 Monitoring of UE Context Release (gNB-CU initiated)

28.5523GPP5G performance measurementsManagement and orchestrationRelease 18TS

In order to monitor the stability of the network and detect the service/connection interruption caused by NG-RAN, monitoring the UE Context Release Command initiated by gNB-CU is an effective method. Collecting the measurements for these events and analysing the releasing cause conveyed in the message, operators could detect the stability of NG-RAN, and could decide a specific means to improve the NG-RAN performance. Moreover, measuring the UE Context Releases on the SSB beam from where the UE CONTEXT is released is useful for analyzing the coverage problem.
