METHOD AND APPARATUS FOR IDENTIFICATION AND TRANSFER IN INTERNET PROTOCOL MULTIMEDIA SUBSYSTEM COLLABORATIVE SESSIONS
First Claim
1. A method, implemented for use in an Internet Protocol (IP) Multimedia Subsystem (IMS) capable wireless transmit/receive unit (WTRU), the method comprising:
- registering an IMS service priority with an IMS network, wherein the IMS service priority indicates the WTRU'"'"'s priority in receiving IMS services; and
receiving an IMS service from the IMS network based on the WTRU'"'"'s IMS service priority.

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.

9. A wireless transmit/receive unit (WTRU) for requesting transfer of Internet Protocol (IP) multimedia subsystem (IMS) collaborative session control, comprising:
-
a processor configured to generate a collaborative session control transfer request for requesting the transfer of control of an Internet Protocol (IP) multimedia subsystem (IMS) collaborative session, wherein the request is carried in an Extensible Markup Language (XML) body of an Session Initiation Protocol (SIP) message; a transmitter, in communication with the processor, configured to transmit the SIP message requesting collaborative session control transfer to an IMS network. - View Dependent Claims (10, 11, 12, 13)

14. A method, implemented by an anchor Application Server (AS) for enabling service continuity in an Internet Protocol (IP) Multimedia Subsystem (IMS) network, the method comprising:
-
requesting a second AS to assume an anchor role for an IMS session, wherein the request is indicated in an SIP message; and relinquishing anchor role for the IMS session to the second AS. - View Dependent Claims (15, 16, 17, 18, 19, 20)
