In the Initial Context Setup message, the NGAP forwards the AMF UE ID, but not in the DL NAS Message, although 38.413 says, in $8.3.1.2 either > The NG-RAN node shall use the AMF UE NGAP ID IE and RAN UE NGAP ID IE > received in the INITIAL CONTEXT SETUP REQUEST message as identification > of the logical connection or in $8.6.2.2 > The NG-RAN node shall use the AMF UE NGAP ID IE and RAN UE NGAP ID IE > received in the DOWNLINK NAS TRANSPORT message as identification of the > logical connection So forward in both cases for harmonization.
