Abstract:
1. A method for supporting Multicast and Broadcast Service (MCBCS) proxy selection for MCBCS and macro diversity in a wireless communication system including a plurality of Access Service Networks (ASNs) for the MCBCS in one Multicast and Broadcast Service (MBS) zone, the method comprising: selecting a first MCBCS proxy among MCBCS proxies in the plurality of ASNs as a master MCBCS proxy, and selecting other MCBCS proxies except for the first MCBCS proxy as slave MCBCS proxies; transmitting, at the first MCBCS proxy, information for macro diversity to the slave MCBCS proxies; transmitting, at the first MCBCS proxy, a notification message including an identifier of the master MCBCS proxy to the slave MCBCS proxies and an MCBCS controller; and receiving, at the first MCBCS proxy, session information from the MCBCS controller in response to the notification message, wherein the master MCBCS proxy first receives an MCBCS join message from a Mobile Station (MS) in the MBS zone.
