Abstract
An apparatus and method for supporting MultiCast and BroadCast Service (MCBCS) proxy selection for MCBCS and macro diversity in a wireless communication system is provided. The apparatus and method selects a first MCBCS proxy among MCBCS proxies in the plurality of ASNs as a master MCBCS proxy, and selects other MCBCS proxies except for the first MCBCS proxy as slave MCBCS proxies, and the first MCBCS proxy transmits information for macro diversity to the slave MCBCS proxies, wherein the master MCBCS proxy first receives an MCBCS join message from a Mobile Station (MS) in one Multicast and Broadcast Service (MBS) zone.

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 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;
- and
- transmitting, at the first MCBCS proxy, information for macro diversity to the slave MCBCS proxies;
- wherein the master MCBCS proxy first receives an MCBCS join message from a Mobile Station (MS) in the MBS zone.
A method for managing MultiCast and BroadCast Service (MCBCS) proxy for MCBCS and macro diversity in a wireless communication system including a plurality of Access Service Networks (ASNs) for MCBCS in one Multicast and Broadcast Service (MBS) zone, the method comprising:
- receiving, at an MCBCS proxy, an MCBCS join message from a Mobile Station (MS) in the MBS zone;
- checking, at the MCBCS proxy, whether the MS is a first MS for MCBCS in the MBS zone based on the MCBCS join message;
- setting, at the MCBCS proxy, the MCBCS proxy itself as a master MCBCS proxy when the MS is the first MS;
- notifying, at the MCBCS proxy, the setting of the master MCBCS proxy to an MCBCS controller for a session start procedure, and notifying the setting of the master MCBCS proxy to other MCBCS proxies so that the other MCBCS proxies are set as slave MCBCS proxies for the MCBCS;
- and
- transmitting, at the MCBCS proxy, Layer 2 information to be assigned for the macro diversity to the slave MCBCS proxies according to the session start procedure.
An apparatus 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 MCBCS in one Multicast and Broadcast Service (MBS) zone, the apparatus comprising:
- a reception unit for receiving an MCBCS join message from a Mobile Station (MS);
- an MCBCS proxy setting unit for checking whether the MS is a first MS for MCBCS in the MBS zone based on the MCBCS join message, and setting a status of the MCBCS proxy as a master when the MS is a first MS;
- a transmission unit for notifying the setting of the master to an MCBCS controller for a session start procedure, and to other MCBCS proxies in the MBS zone so that the other MCBCS proxies are set as slave MCBCS proxies for the MCBCS, or transmitting Layer 2 information to the other MCBCS proxies for the macro diversity;
- and
- an information generation unit for generating the Layer 2 information according to the session start procedure, and transmitting the Layer 2 information to the transmission unit.
