Abstract

L'invention concerne un système permettant d'établir le canal de données de diffusion et de multidiffusion dans le système de communications sans fil. La granularité pour établir le canal de données réside dans le fait que le canal de données de diffusion et de multidiffusion est établi pour chaque zone de service de diffusion et de multidiffusion ou pour chaque flux de service de multidiffusion particulier, le service de données de diffusion et de multidiffusion étant désigné MBS en abrégé. Le système comporte le serveur MBS, la passerelle d'accès et la station de base interconnectés tour à tour. Le serveur MBS sert à configurer et à autoriser les services MBS, à transmettre les informations de demande d'établissement d'un canal de données, et à attribuer l'identité du flux de service MBS, SFID, et l'identité de connexion MBS, CID. La passerelle d'accès sert à communiquer les messages entre le serveur MBS et les stations de base, à attribuer l'identité de canal de données MBS, et à établir le canal de données avec la passerelle d'accès. En comparaison avec la technique actuelle, le canal de données de diffusion et multidiffusion est établi sur la base de la granularité de la zone MBS ou du flux de service de multidiffusion, ce qui permet de sauvegarder efficacement la ressource de largeur de bande de liaison.
