摘要:
A wireless communication method and device may be used to perform a media independent handover between technologically diversified access networks. A wireless transmit/receive unit (WTRU) may be configured to communicate with a plurality of technologically diversified access networks, such as Institute of Electrical and Electronics Engineers (IEEE) 802.X networks and Third Generation Partnership Project (3GPP) networks. The WTRU may include a plurality of access network specific protocol stacks and a media independent handover (MIH) function. The WTRU may be configured to communicate information with each of the plurality of access network specific protocol stacks using protocols specific to each to the plurality of access network protocol stacks.
摘要:
A method and system for integrating media independent handover (MIH) under IEEE 802.21 and unlicensed mobile access (UMA) are disclosed. A public land mobile network (PLMN) and an unlicensed mobile access network (UMAN) are concurrently deployed. UMA is supported such that a multi-mode wireless transmit/receive unit (WTRU) may access the UMAN to receive PLMN services through the UMAN. MIH entities are included both in the WTRU and the UMAN and the MIH entity of the WTRU monitors handover events and information and generates a handover trigger for handover between the PLMN and the UMAN. The MIH entity in the UMAN interacts with the MIH entity of the WTRU to report a remote event, handover information and command.

A wireless communication system including at least one IEEE 802 multi-stack wireless transmit/receive unit (WTRU) and a plurality of technologically diversified access networks, such as IEEE 802.X networks and Third Generation Partnership Project (3GPP) networks, that are concurrently deployed. Both the multi-stack WTRU and the technologically-diversified networks include a media independent handover (MIH) function. The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and authorization procedures based on the MIH information, obtain a local Internet protocol (IP) address, establish a tunnel to a packet data gateway (PDG) in a 3GPP core network, construct a care of address (CoA) and register the CoA with a home agent of the WTRU, whereby data destined for the WTRU is routed via the home agent through a new tunnel established between the home agent and a foreign agent based on the CoA.

UMA is supported such that a multi-mode wireless transmit/receive unit (WTRU) may access the UMAN to receive PLMN services through the UMAN. MIH entities are included both in the VVTRU and the UMAN and the MIH entity of the WTRU monitors handover events and information and generates a handover trigger for handover between the PLMN and the UMAN. The MIH entity in the UMAN interacts with the MIH entity of the WTRU to report a remote event, handover information and command.
摘要:
A method and apparatus for triggering procedures to handover an ongoing communication session between a mobile station (MS) and a correspondent node (CoN) from via a first network of a first type to via a second network of a different type. Communication session continuity is maintained by transferring communication session context information when a handover is imminent from a network component in a first network path to a network component in a second network path, and by forwarding downlink and uplink signals via the network components in both the first and second network paths until the ongoing communication session can be established via the second network path. The context information includes the session communication parameters, such that the second network path can allocate resources and establish routing between the MS and the CoN.

A method and apparatus for sending uplink control information by a multi-mode wireless transmit/receive unit (WTRU) capable of operating on multiple component carriers of a plurality of radio access technologies (RATs) for multi-RAT operation are disclosed. The WTRU may generate uplink control information (UCI) pertaining to a first RAT and a second RAT, wherein the UCI may include a first plurality of hybrid automatic repeat request acknowledgements (HARQ-ACKs) pertaining to a plurality of downlink (DL) transmissions of the first RAT and a second plurality of HARQ-ACKs pertaining to a plurality of DL transmissions of the second RAT. The WTRU may multiplex at least part of the generated UCI pertaining to the first RAT and at least part of the generated UCI pertaining to the second RAT onto a physical channel on a component carrier of the second RAT.
