Method and Apparatus For Data Packet Transport In a Wireless Communication System Using an Internet Protocol
First Claim
1. An infrastructure apparatus for providing broadcast transmissions from a wired communication network to a wireless communication network, the infrastructure apparatus comprising:
- means for establishing one or more secure tunnels to communicate with one or more infrastructure entities of the wireless communication network;
means for joining a multicast tree associated with the wired communication network;
means for receiving a multicast transmission over the multicast tree, wherein the multicast transmission comprises an encapsulated packet; and
means for transmitting the encapsulated packet over the one or more secure tunnels.

Abstract
Method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. A multicast tree is built between nodes through neighboring routers. The multicast tree forms a tunnel through which the broadcast content is transmitted. The broadcast message is encapsulated in an Internet Protocol packet for transmission through the multicast tree. At least one multicast tree is formed between the Internet portion of the system and the wireless portion of the system, such as the Access Network. In one embodiment, an external multicast tree is formed between a content source and a packet data service node, and an internal multicast tree is formed between the packet data service node and a packet control function node.
