Method and apparatus for supporting multicast/broadcast in wireless communication system
First Claim
1. A multicast/broadcast method comprising:
- receiving an Internet Protocol (IP) packet from an upper layer;
determining whether the received IP packet comprises at least one of a multicast destination address and a broadcast destination address; and
transmitting a packet in which a connection identifier (CID) for the multicast or the broadcast is selectively attached to the received IP packet according to a result of the determination.

Abstract
A method and apparatus for supporting a multicast/broadcast in a wireless communication system are provided. A multicast/broadcast method receives an Internet Protocol (IP) packet from an upper layer, determines whether a multicast destination address or a broadcast destination address is contained in the received IP packet, and transmits a packet in which a connection identifier (CID) for the multicast or the broadcast is selectively attached to the received IP packet according to a result of the determination. Also, the multicast/broadcast method may receive an IP packet from a mobile station, determine whether a first CID for the multicast or the broadcast is contained in the received IP packet, and transmit a packet in which the first CID of the received IP packet is selectively replaced with a second CID according to a result of the determination.
