How can we check which AMF is assigned to the UE?

Dear Experts.

Iin case of 5G SA network, during log file analysis, how can we check which AMF is assigned to the UE?

Scenario: we have AMF in pool and call setup time is high in some cases.

Thanks in advance.

Log analysis tool is XCAP.

  1. Check the in the log UE or eNodeB and CORE side. Probably RRC Connection reestablishment request doesn’t happen if ROHC or device do not support QCI1 over RLCAm

  2. Something is wrong in the configuration… Do you have VoNR?

As far as I know, you cannot locate core nodes from RAN traces.

Most networks have now pool of core nodes serving RAN area, you need to trace call on eNB/gNB to find the IP address or tunnel-IDs to infer the service AMF etc.
