Abstract

L’invention concerne un procédé et un appareil de notification de la prise en charge du service de diffusion multimédia multidestination (MBMS), le procédé comprenant les étapes suivantes : un contrôleur de réseau de radiocommunication de dérive (DRNC) reçoit un message de demande d’établissement de liaisons radio en provenance d’un contrôleur de réseau de radiocommunication serveur (SRNC), le message de demande d’établissement de liaisons radio contenant une cellule de liste de services supports MBMS; le DRNC transmet au SRNC un message de réponse d’établissement des liaisons radio, le message de réponse d’établissement de liaisons radio indiquant si le DRNC prend en charge le MBMS selon qu’il contient ou non une cellule de liste de services supports MBMS active. L’invention remédie au problème classique du nombre excessif de liaisons radio établi du fait que le SRNC est incapable d’établir si les cellules du DRNC prennent en charge le service MBMS. Selon l’invention, le SRNC peut établir en connaissance de cause les liaisons radio adaptées aux cellules du DRNC qui prennent en charge le service MBMS.
