Abstract
The invention claims a method and apparatus for a proxy mobile internet protocol (PMIP) supporting special multicast local mobility anchor (LMA) and a mobile access gateway (MAG). anti-LMA the internet protocol (IP) address assigned to a wireless transmit receive unit (WTRU) the WTRU processing the IP address and to a serving MAG transmits a router solicitation message. The WTRU receives a unicast service on the first IP address and a second IP address for a multicast service. Generally the method and apparatus allows the use of proxy mobile IP architecture interface and process for realizing multiple multicast mobility. More specifically described herein is for operation of a multicast service polymerization PMIP tunnel. when the mobile node moves from one MAG to another MAG the LMA in and between the LMA when moving can realize multicast mobility. and the mixed network of bidirectional network and only the downlink multicast network between multicast mobility can be realized.
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.
