Q/A

We wanted to add “Selected PLMN ID” to the Initial UE Message from N3IWF to AMF.
Can we get some help on adding this.

hi @sujababuraj
in https://github.com/free5gc/n3iwf/blob/a4088a8797c95499c7f69b5f50e80694cde476e7/internal/ngap/handler/handler.go#L2815 HandleSendInitialUEMessage function will handle the InitialUEMessage, I think you can modify here to add SelectedPLMNID in Initial UE Message, and N3IWF has define SelectedPLMNID information element in https://github.com/free5gc/n3iwf/blob/a4088a8797c95499c7f69b5f50e80694cde476e7/internal/ngap/message/3gpp_type.go#L17, just for reference.

Best Regard,
James
