<P>PROBLEM TO BE SOLVED: To provide a method and apparatus for data packet transport in a wireless communication system using an Internet Protocol. <P>SOLUTION: There are provided a method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. A trigger recognized at a transmission node initiates a broadcast transmission, and the resultant set up of a transmission path. A termination trigger then indicates that the transmission node is not serving users who desire the broadcast transmission, and in response to this, the transmission path is shut down. In one embodiment, a multi-cast call, such as a group call, may be transmitted to active users via uni-cast channel(s) or multi-cast channel(s) based on predetermined criteria, such as the number of active users. <P>COPYRIGHT: (C)2012,JPO&INPIT |
