Abstract: A first media independent handover function (MIHF) receives a media indep endent handover (MIH) capabilities discovery request from a second MIHF and generates a MIH capabilities discovery response message, including one or mo re parameters. Then the first MIHF then sends the MIH capabilities discovery response to the second MIHF. Based on the information contained in the MIH capabilities discovery response, the first MIHF may receive a handover reque st message from the second MIHF. The one or more parameters included within the discovery response message indicates the specific technologies for which the first MIHF supports a MMB handover. The one or more parameters may incl ude a list of the technologies for which a make-before-break (MMB) handover is supported. For example, a parameter may use a specific bit structure wher ein each bit is a Boolean representation of whether MMB handover is supporte d for a specific type of technology.

Abstract: A method and system for supporting a handover between a circuit-switched (CS) domain and an Internet protocol (IP) multimedia subsystem (IMS) domain to provide call continuity are disclosed. The system includes a wireless transmit/receive unit (WTRU) and a wireless network. The WTRU includes a call continuity control entity for supporting call continuity between a CS domain and an IMS domain, and a media independent handover (MIH) entity configured to provide MIH services for providing information in a media independent manner. The wireless network includes an MIH entity for providing MIH services for collecting and forwarding information in a media independent manner. A handover between the CS domain and the IMS domain is triggered based on information obtained via MIH services from the MIH entities. The information may be exchanged via an MIH information server.

Abstract: 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 Internee 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.

Abstract: A method for controlling behavior of lower layer links related to media independent handover (MIH) of a mobile user comprises sending a MIH link actions request primitive from a MIH User entity to a MIH function (MIHF) for requesting actions to be executed on a set of lower layer links to heterogeneous radio access technology (RAT) networks. The primitive includes parameters that indicate the requested actions and an execution time delay. Confirmation primitives are sent back the MIH User entity to convey the results of the execution attempts on the requested actions.

Abstract: A measurement report request message (350) is sent to a measurement terminal (314) in the wireless local area network (WLAN). A measurement report response message sent from the measurement terminal is evaluated by the media access control (MAC) function (334) to determine whether a handover condition exists. A media independent handover (MIH) trigger is generated by the MAC function if the handover condition exists. The MIH trigger is sent to MIH function (340). The MIH and MAC functions are located in the same network node. Independent claims are included for the following: (1) apparatus for generating MIH trigger; and (2) communication frame for providing MIH information.
