Abstract

L'invention concerne un procédé et un système d'obtention de la capacité de session du participant à une session dans un système de communication multipartie. Principalement, dans un système de communication multipartie, un utilisateur appelant envoie une demande d'établissement de session à un utilisateur appelé via le serveur de session et l'utilisateur appelé envoie le résultat de négociation contenant sa capacité de session au serveur de session, lequel informe d'autres participants à la session de l'information sur la capacité de session obtenue du participant à la session selon la politique préétablie. Le système comprend essentiellement le serveur de session et le participant à la session. Ainsi, le participant à la session peut obtenir l'information sur la capacité de session d'autres participants selon le message de notification envoyé par le serveur de session.
