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-stack wireless transmt/receive unit (WTRU) and a plurality of technologically diversified acess 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 includ a media indipendent handover (MIH) function. The WTRU is configured to read MIH information transmitted from one of the IEEE 802.X networks, trigger 3GPP authentication and atuhorization procedures based on the MIH information, obtain a local Internet Protocol (IP) address, establish a tunnel to a packet data gateway (PDG) un a 3GPP core network, constructed 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.
