Abstract  Abstract

The data packet transmission method and device in the wireless transmission system which supports the broadcasting transmission multicast trees is established between the nodes by closing router. The multicast trees form passage through which the broadcasting message can be transmitted out. The broadcasting message is packed in the internet protocol packet which is transmitted through multicast trees. There should form at least one multicast tree between the internet part and the wireless part of the system such as access network. In one implementary case there should form external multicast trees between the content source and the packet data serving node and form internal multicast trees between the packet data serving node and packet control-function node.
