Abstract

La présente invention concerne un procédé et une station de base permettant d'activer le service multimédia de diffusion multicast de la communauté cible, ledit procédé comprenant les étapes consistant à : après que la station de base source a acquis les informations de service multimédia de diffusion multicast des stations de base adjacentes, sélectionner la station de base cible ; déterminer le service multimédia de diffusion multicast associé au changement d'utilisateur dans la communauté cible selon les informations de service multimédia de diffusion multicast de la station de base cible ; si non, envoyer le message de service multimédiade diffusion multicast associé au changement d'utilisateur à la station de base cible ; après que la station de base cible a reçu le message de service multimédia de diffusion multicast, activer le service multimédia de diffusion multicast correspondant à la communauté cible. La présente invention peut activer le service multimédia de diffusion multicast de la communauté cible tout en changeant d'utilisateur qui reçoit le service multimédia de diffusion multicast, peut assurer la continuité du service utilisateur de monodiffusion, peut réduire le délai d'activation du service multimédia de diffusion multicast par la communauté cible, et peutamener le service multimédia de diffusion multicast à acquérir la bonne continuité.
