1. A method for enhancing NAS (non-access stratum) signaling in RACS (radio capability signaling optimization) of a wireless network, the method comprising:
receiving, by a UE (user equipment), an RC_ID_IE (radio capability identity information element) with an RC_ID (radio capability identity) from a server of the wireless network to optimize a transmission of the UE;
sending, by the UE, a registration request message to the server to establish NAS signaling between the UE and the server;
establishing, by the UE, the NAS signaling between the UE and the server; and
enhancing, by the UE, the NAS signaling between the UE and the server by performing at least one of:
receiving a registration accept message with an RC_ID deletion IE (radio capability identity deletion information element) from the server, and sending a registration complete message to the server using existing NAS signaling and without starting a release timer in response to receiving the RC_ID deletion IE in the registration accept message; and
receiving the registration accept message with the RC_ID deletion IE from the server and not sending the registration complete message to the server in response to receiving the RC_ID deletion IE in the registration accept message.
