Abstract
The present invention relates to a method and apparatus for transmitting a data packet in a wireless transmission system supporting broadcast transmission. Multicast trees are formed between nodes through neighboring routers. The multicast tree forms a tunnel through which broadcast content is transmitted. The broadcast message is encapsulated in an internet protocol packet for transmission over the multicast tree. One or more multicast trees are formed between the wireless portion of the system, such as an access network, and the Internet portion of the system. In one embodiment, an outer multicast tree is formed between the content source and the packet data service node, and an inner multicast tree is formed between the packet data service node and the packet control function node.
