A multimedia broadcast multicast type service (MBMS) is offered to mobile subscribers. A RAN node communicates with one or more radio base stations that transmit and receive information with mobile subscriber terminals, some of which subscribe to the MBMS. The RAN node communicates with multiple core network packet data nodes that receive MBMS data for delivery to the RAN node. One of the multiple core network packet data nodes is selected to provide the MBMS data associated with the MBMS to the RAN node. The others are instructed not to provide the MBMS data, but they still perform other MBMS support functions for their mobile terminals such as MBMS charging, etc.
L'invention concerne un service de type diffusion sélective multimédia (MBMS) offert à des abonnés mobiles. Un noeud RAN communique avec au moins une station de base radio qui transmet et qui reçoit des informations de terminaux d'abonnés mobiles. Certains de ces terminaux sont abonnés au MBMS. Le noeud RAN communique avec plusieurs noeuds de données de paquets de réseaux centraux qui reçoivent des données MBMS à distribuer au noeud RAN. Un de ces noeuds de données de paquets de réseaux centraux est sélectionné pour fournir les données MBMS associées au MBMS du noeud RAN. Les autres reçoivent des instructions pour qu'ils ne fournissent ces données MBMS, mais pour qu'il continuent d'assumer d'autres fonctions de support MBMS pour les terminaux mobiles, notamment le chargement MBMS, etc.
