Abstract

La présente invention concerne un procédé de traitement d'adressage de groupe, un dispositif, une passerelle d'intercommunication MTC, et une passerelle d'API. Le procédé consiste à : recevoir une demande d'adressage de groupe envoyée par un serveur d'application (AS), la demande d'adressage de groupe contenant un identifiant de groupe; déterminer une zone de desserte de service de diffusion/multidiffusion multimédia (MBMS) d'un MBMS pour un adressage de groupe d'après l'identifiant de groupe; et initier une livraison de données MBMS d'après la zone de desserte de MBMS déterminée, la livraison de données MBMS contenant un message d'adressage de groupe. La présente invention résout le problème lié, dans l'état de la technique, au fait qu'un UE ne peut pas être adressé et que le surdébit d'un système augmente lorsqu'un adressage de groupe est implémenté vis-à-vis d'un UE via une diffusion MBMS. L'invention améliore d'autre part l'efficacité d'adressage d'un UE.
