Abstract: A method and apparatus for handover of a dual mode wireless transmit/receive unit (WTRU) from an LTE system to a GERAN system uses measurements of the LTE and GERAN frequencies and a decision by a source evolved Node B to perform the handover. A GERAN access procedure includes PS attach messages exchanged between the WTRU and the target base station controller and a target SGSN. Alternatively, the GERAN access procedure uses RAN mobility information messages exchanged by the WTRU and the target base station controller and a relocation detect message by the source evolved Node B.

Abstract: A wireless communication system and method of implementing an evolved system attachment procedure are disclosed. The system includes a first core network and a second core network which is evolved from the first core network. A wireless transmit/receive unit (WTRU) sends an attach request message to the second core network. The second core network activates a packet data protocol (PDP) context and sends an attach accept message to the WTRU. The attach accept message includes information regarding the PDP context. The second core network constructs a session and mobility management (SMM) context for session management (SM) and mobility management (MM) for the WTRU.

Abstract: A wireless communication system for supporting multimedia services (MMS) provided to a user of a wireless transmit/receive unit (WTRU) which communicates with the wireless communication system. The wireless communication system includes a third generation partnership program (3GPP) universal mobile telecommunications system (UMTS), a wireless local area network (WLAN) and an MMS server. The MMS server stores at least one MMS message for the WTRU in a memory until the WTRU retrieves the message. The 3GPP UMTS includes an internet protocol short message gateway (IP-SM-GW) having a short message service (SMS) proxy. The WTRU is registered with the SMS proxy to establish SMS connectivity, and is also registered with the MMS server to establish MMS connectivity. The WTRU is notified when the MMS server receives an MMS message for the WTRU. The WTRU then retrieves the MMS message from the memory of the MMS server.

Abstract: A method and system for supporting an evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN) are disclosed. The system includes a wireless transmit/receive unit (WTRU), a UTRAN and an E-UTRAN. The UTRAN sends to the WTRU a list of available radio access technologies in a coverage area of the UTRAN. The list includes information related to the E-UTRAN. The WTRU receives the list and may initiate a handoff based on the list. The WTRU then sends its multi-mode/multi-RAT capability information including the E-UTRAN capability to the UTRAN. The UTRAN then sends a measurement capability message to the WTRU. The measurement capability message includes parameters necessary for performing measurements on an E-UTRAN channel. The WTRU performs measurements based on the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to the E-UTRAN based on the measurement results.

Abstract: Methods and systems for a mobile node of a communication network to use mobile internet protocol (MIP) to query a node, such as a home agent (HA) of the communication network to obtain information regarding other nodes that may be registered with the same node of the network, such as the HA, or nodes that may be registered with the same HoA. Also, a node of a communication network, such as a HA, may send to registered nodes of the communication network via MIP un-requested information regarding nodes that may be registered with the HA, or nodes that may be registered with the same HoA. A node of the communication network may initiate an inter-unit transfer (IUT) to one or more other nodes of the communication network using the information regarding nodes that may be registered with the HA or registered with the same HoA.

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.
