Abstract

L'invention concerne un procédé et un système permettant de fournir un service de notification de conférence multimédia entre un réseau de nouvelle génération (NGN) et un sous-système multimédia IP (IMS). Le procédé permettant à une passerelle d'émettre un message de service de notification de conférence multimédia entre l'IMS et le NGN, consiste : à recevoir un message d'abonnement à une conférence envoyé par un serveur d'applications de service de conférence multimédia d'une partie, l'IMS ou le NGN ; et à transmettre le message d'abonnement à la conférence au serveur d'applications de service de conférence multimédia de l'autre partie. Les modes de réalisation de la présente invention permettent d'établir une connexion entre un utilisateur de l'IMS ou du NGN et le serveur d'applications d'un réseau de l'autre partie.
