Abstract: Apparatus and method for providing an automatic handoff process of a dual-mode user equipment (UE) from either a wireless local area network (WLAN) to a universal mobile telecommunications system (UMTS) or from a UMTS to a WLAN. Handoffs may be initiated by the UE, based upon user preference, signal quality, comparison of location coordinates of the UE and the system to be switched to or signal quality. The available channels of one system may be sent to the UE by the other system or the UE may monitor channels of the system to be switched to and lock on to one. The handoff may also be initiated by the UMTS, the selection being power-based.

Abstract: A WTRU may receive a first data flow from a source device such as a correspondence node and perform a seamless IUT such that the correspondent node is unaware that the flow has been transferred to a different WTRU. The WTRU may register with a first home agent, wherein the first home agent receives a plurality of messages addressed for a home address. The home agent may forward the messages to the WTRU at a first care-of-address. The WTRU may send a binding update to the first home agent. The binding update may comprise a second traffic selector and a second action. The second action may specify that a second message of the plurality of messages is to be forwarded to a different WTRU when the second message matches the second traffic selector.

The registration message further indicates that the WTRU is configured to receive Short Message Service (SMS) messages from the cellular network via the WLAN. The WTRU receiver receives services that include Short Message Service (SMS) messages.

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.

In the reporting cycle, all the devices may wake up and access the system to connect to the M2M system to upload data.

Abstract: Techniques for inter-user equipment (UE) transfer (IUT) are disclosed. An application server receives an IUT request for transfer of a media session toward at least one UE such that a media stream is played by at least two UEs that are geographically separated after the transfer. The application server triggers inter-destination media synchronization (IDMS) for group synchronization of the media session among the UEs. The media stream may be anchored at a media server, and a media synchronization application server for the IDMS may be running at the media server. Alternatively, the media stream may be anchored at a media resource function (MRF), and a media synchronization application server for the IDMS may be running at the MRF.

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.

The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.

Abstract: Methods and systems are disclosed facilitate differentiated QoS service for packets within a single packet stream. For example, extended QCI values may be used to differentiate service of video packets associated with different priorities. A flexible representation of QoS requirements/parameters is disclosed where QoS may be defined as a hyperspace that is a function of base QoS parameters.

Techniques may be utilized to exposing more information to a data transmission network regarding the type of video packets (and/or other packets) being transmitted.

Abstract: Systems, methods, and instrumentalities may implement service-based discovery in a network, such as a 3GPP or 3GPP2 network. A Discovery Server may be used to query and find services offered by the network or by entities that interface with the network. Situational context information or policy information, or both, may be communicated to the discovery server so that the Discovery Server can provide context-aware and policy-based discovery services. The Discovery Server may be used to control which of the entities that interface with the network can discover one another. The Discovery Server may support queries based on, for example, the type of MTC entity, the type of services hosted on the entity, the availability times of the entity, types of protocols supported, levels of Quality of Service (QoS) supported, and MTC-IWF services.
