Abstract: NAS signaling between a UE and a server is enhanced by performing one of: sending a registration complete message to the server using existing NAS signaling and without starting a release timer in response to receiving an RC_ID deletion IE in a registration accept message; and not sending the registration complete message to the server in response to receiving the RC_ID deletion IE in the registration accept message. A registration procedure is reinstated based on a stored RC_ID.
