A method and apparatus for delivering media to a group of target communication devices provides for multicasting media to the group of target communication devices to save network resources. The disclosed embodiments provide for a significant reduction in network traffic and media processing time by transmitting media in multicast transport mode, where a single copy of the media destined for a group of target recipients is transmitted to a wireless infrastructure over the multicast path. The wireless infrastructure replicates and transmits one copy of the media to each of the target recipients that are assigned to dedicated channels, but multicasts one copy of the media to the target recipients that are assigned to a shared channel.
L'invention concerne un procédé et un appareil de distribution de médias à un groupe de dispositifs de communication cibles, qui permettent d'économiser des ressources réseau. Les modes de réalisation de l'invention permettent de réduire significativement le trafic réseau et le temps de traitement des médias par transmission des médias en mode de transport multidiffusion, selon lequel une seule copie du média destiné à un groupe de destinataires cibles est transmise à une infrastructure sans fil par un chemin de multidiffusion. Cette infrastructure sans fil répond et transmet une copie du média à chaque destinataire cible associé à un canal réservé, mais transmet par multidiffusion une copie du média aux destinataires cibles qui sont associés à un canal partagé.
