    摘要: A method and an apparatus for a proxy mobile Internet protocol (PMIP) supporting a dedicated multicast local mobility anchor (LMA) and mobile access gateway (MAG) is provided. The LMA assigns an Internet Protocol (IP) address to a wireless transmit receive unit (WTRU) that processes the IP address and sends a router solicitation message to a serving MAG. A WTRU is disclosed to receive a first IP address that is for unicast service and a second IP address that is for multicast services. Generally, the method and apparatus proposes architecture, interfaces, and procedures to enable multicast mobility using Proxy Mobile IP. More specifically operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG, intra-LMA, and inter-LMA. And, Multicast mobility is enabled between bidirectional network and downlink only multicast network in a hybrid network.

    摘要: A wireless transmit/receive unit (WTRU) may include an IEEE 802.16 modem, a universal mobile telecommunication system (UMTS) modem and a media independent handover (MIH) entity. Software application programming interfaces provide the MIH entity with mechanisms to receive information about IEEE 802.16 and UMTS links, control IEEE 802.16 and UMTS modems for handover, discover an MIH server and IP multimedia system nodes, trigger mobile IP handover, etc. If an IEEE 802.16 link has been successfully established, the MIH entity starts an MIH session. When the IEEE 802.16 modem indicates that a connection is going to be terminated, the MIH entity activates the UMTS modem for handover. If the IEEE 802.16 modem indicates that a link parameter has crossed a threshold, the MIH entity sends IEEE 802.16 and WCDMA signal measurements to an MIH server. After receiving an MIH switch request, the MIH entity initiates handover to the UMTS network.
