Abstract

L'invention concerne un procédé de communication et un dispositif de communication, le procédé consistant à : déterminer au moins une zone d'un réseau monofréquence de radiodiffusion multimédia (MBSFN) parmi l'ensemble des zones MBSFN incluses dans une zone de service de radiodiffusion multimédia multidestinataire (MBMS) d'un service MBMS, la ou les zones MBSFN ne comprenant une première zone MBSFN et une seconde zone MBSFN concomitantes, et un ensemble de cellules de la première zone MBSFN étant un sous-ensemble de cellules de la seconde zone MBSFN, l'ensemble des zones MBSFN comprenant la première zone MBSFN et la seconde zone MBSFN ; et envoyer un message de commande MBMS à une station de base d'une cellule de chaque zone MBSFN de la ou des zones MBSFN. Le procédé de communication et le dispositif de communication décrits dans un mode de réalisation de la présente invention sont aptes à résoudre le problème de gaspillage de ressources de transmission provoqué par l'envoi d'un message de commande MBMS aux stations de base des cellules de l'ensemble des zones MBSFN, économisant ainsi les ressources réseau et améliorant les performances du système.
