Abstract  Abstract

PROBLEM TO BE SOLVED: To provide 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).

SOLUTION: The LMA assigns an IP address for unicast services and an IP address for multicast services to a wireless transmit receive unit (WTRU) that sends a router solicitation message to a serving MAG. The serving MAG updates a binding update list for the WTRU and for the LMA. Multicast mobility is enabled when mobile nodes move from one MAG to another MAG intra-LMA and inter-LMA. Multicast mobility is enabled between a bidirectional network and a downlink only multicast network in a hybrid network.
