Claim Text:
1. A method of Inter-User Equipment (UE) Transfer (IUT) for use in a Home enhanced-Node B (H(e)NB), the method comprising: receiving, at an H(e)NB Internet Protocol (IP) client in the H(e)NB, an IUT session transfer command via IP Multimedia Subsystem (IMS) signaling from an IMS network, wherein the received IUT session transfer command requests an IUT to transition an IMS session that is initially between an IMS-capable wireless transfer/receive unit (WTRU) and a remote party to thereafter be between a non-IMS capable WTRU and the remote party, wherein the H(e)NB IP client interfaces between the IMS network and the non-IMS capable WTRU, wherein the IMS session has a controller, wherein the H(e)NB IP client is the controller of the IMS session; translating, at the H(e)NB IP client, the IUT session transfer command to a non-IMS based message; transmitting, from the H(e)NB IP client to the non-IMS capable WTRU, the translated non-IMS based message; receiving, at the H(e)NB IP client, a release-media-request message from the IMS-capable WTRU to release a particular media flow of the IMS session; releasing, at the H(e)NB IP client, the particular media flow of the IMS session; and transmitting a release-media-acknowledgement message regarding the particular media flow from the H(e)NB IP client to the IMS-capable WTRU via the IMS network.
