I was comparing UE Context Release Cmd (defined in 36.413) with the NG-AP (38.413) UE Context Release Cmd. I couldn't realize the scenario in which only the AMF allocated UE NG-AP ID will be included in UE Cntxt Release Cmd. In LTE, both the S1-AP IDs were mandatory to send in UE Ctxt Rel Cmd from MME to eNodeB.
It would be helpful if someone can provide the reason.
Thanks in advance.
