Title

(EN) PROVIDING A MULTICAST SERVICE USING A MULTICAST GROUP-SOURCE KEY

(FR) FOURNITURE D'UN SERVICE MULTIDESTINATION AU MOYEN D'UNE CLE DE GROUPE-SOURCE MULTIDESTINATION

Abstract

(EN) Providing a multicast service to a mobile node includes receiving a first request to join a multicast group from a first cell site. The first request requests that a first mobile node be permitted to join the multicast group. A first multicast source operable to provide content to the first mobile node is identified. The multicast group and the first multicast source are associated to yield a first group-source combination. A first key is assigned to the first group-source combination, and the first key is provided to the first cell site.

(FR) L'invention concerne la fourniture d'un service multidestination à un noeud mobile consistant à recevoir une première demande de ralliement à un groupe multidestination émanant d'un premier site cellulaire. La première demande requière qu'un premier noeud mobile soit autorisé à rallier le groupe multidestination. Une première source multidestination conçue pour fournir un contenu au premier noeud mobile est identifiée. Le groupe multidestination et la première source multidestination sont associés de manière à produire une première combinaison groupe-source. Une première clé est attribuée à la première combinaison groupe-source et la première cle est fournie au premier site cellulaire.
