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 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.

L'invention concerne un procédé et un système d'acheminement de paquets de données dans un système de communication sans fil acceptant des transmissions de radiodiffusion. Un déclencheur identifié au niveau du noeud de transmission démarre une transmission de radiodiffusion ainsi que l'initialisation résultante d'un trajet de transmission. Un contact d'arrêt indique alors que le noeud de transmission ne dessert pas des utilisateurs désirant la transmission de radiodiffusion; et en réponse, le trajet de transmission est fermé. Dans un mode de réalisation, un appel à plusieurs destinataires, tel qu'un appel de groupe, peut être transmis à des utilisateurs actifs par le biais d'une ou de voies à destinataire unique ou d'une ou de voies à plusieurs destinataires, selon des critères préétablis, tels que le nombre d'utilisateurs actifs.
