WIRELESS COMMUNICATION METHOD AND SYSTEM FOR IMPLEMENTING MEDIA INDEPENDENT HANDOVER BETWEEN TECHNOLOGICALLY DIVERSIFIED ACCESS NETWORKS.

摘要

A wireless communication system including at least one IEEE 802 multi-stackwireless transmit/receive unit (WTRU) and a plurality of technologically diversifiedaccess networks, such as IEEE 802.X networks and Third Generation PartnershipProject (3GPP) networks, that are concurrently deployed. Both the multi-stackWTRU and the technologically-diversified networks include a media independenthandover (MIH) function. The WTRU is configured to read MIH information transmittedfrom one of the IEEE 802.X networks, trigger 3GPP authentication and authorizationprocedures 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 tunnelestablished between the home agent and a foreign agent based on the CoA.
