Abstract:
A method of improving initial IMS registration after 403 Forbidden response is proposed. A UE sends a SIP register to an IMS server for initiating IMS registration. The initial IMS registration fails and the UE receives a SIP message with a 403 Forbidden response code. In the 403 Forbidden response code, the IMS server includes an XML body and uses the <reason> header value of the XML body to indicate an error type (e.g., temporary or permanent) followed by a retry-after timer value. As a result, the network can indicate to UE whether the IMS registration rejection is permanent or is due to some temporary internal failure. By adding the retry-after timer value, the network can indicate to UE when to retry the next IMS registration.

Claim (Index 12):
The UE of  claim 11 , wherein the error message comprises a SIP Error 403 forbidden response code.
