Abstract  Abstract

Method and apparatus for data packet transport in a wireless communication system using the Internet Protocol (IP) United States Patent Application 20070249405 Kind Code: A1 A method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmission. . A multicast tree is constructed between nodes through neighboring routers. The multicast tree forms a tunnel through which broadcast content is transmitted. Broadcast messages are encapsulated in IP packets for transmission through a multicast tree. At least one multicast tree is formed between the Internet portion of the system, such as an access network, and the wireless portion of the system. In one embodiment, the outer multicast tree is formed between the content source and the packet data service node, and the inner multicast tree is formed between the packet data service node and the packet control function node.
