    摘要: 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.

    摘要: Inter-Working Function (IWF) for interfacing between a Wireless Local Area Network (WLAN) and a communication system. The IWF may contain sufficient information to authenticate a user access to the WLAN, or the IWF may need to request authentication from the communication system. In one embodiment, the IWF sends an access challenge to the WLAN for a user. The IWF may then pass a response to the challenge on to the communication system for authentication. The IWF allows the WLAN to use the authentication capability of the communication system for local authentication.
