METHOD AND APPARATUS FOR DATA PACKET TRANSPORT IN A WIRELESSCOMMUNICATIONS SYSTEM USING AN INTERNET PROTOCOL |
摘要 |
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. In one embodiment, a mul ti- 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. |
