<p><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: The present invention relates to a method and apparatus for data packet transport in a wireless transmission system supporting broadcast transmissions. A trigger recognized at the 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 desiring the broadcast transmission, and in response the transmission path is shut down. 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 a predetermined criteria, such as number of active users. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
