Abstract:
A method and apparatus are described for performing Internet Protocol (IP) Multimedia Subsystem (IMS) operation. A wireless transmit/receive unit (WTRU) registers an IMS service priority with an IMS network. The IMS service priority indicates the WTRU's priority in receiving IMS services. The WTRU may receive an IMS service from the IMS network based on the WTRU's IMS service priority. The IMS service priority may be indicated using a priority value and the WTRU may use Session Initiation Protocol (SIP) messaging to signal with the IMS network. The WTRU may register the service priority value using a q-value parameter in an SIP Contact field header. The WTRU may also register a public user identity with the IMS network and the public user identity may be shared with other IMS-capable WTRUs.
