Abstract  Abstract

A method and apparatus are provided for Proxy Mobile Internet Protocol (PMIP) that supports a dedicated multicast local mobility anchor (LMA) and a mobile access gateway (MAG). 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 the Serving MAG. The WTRU is initiated to receive a first IP address for unicast service and a second IP address for multicast services. In general, methods and apparatus propose architectures, interfaces, procedures for enabling multicast mobility using proxy mobile IP. More specifically, the operations of aggregated PMIP tunnels for multicast services are described. Multicast mobility is enabled when mobile nodes move from one MAG to another, within the LMA, and between LMAs. And multicast mobility is enabled between the downlink dedicated multicast network and the bidirectional network of the hybrid network.
