Abstract

Ce procédé permettant de mettre un terme à une session de communication à multiples abonnés et le serveur de mise en oeuvre du procédé permettent, en cours de session, de mettre un terme à la session actuelle de messagerie vocale instantanée et de libérer les ressources de session des participants, une fois que les conditions de finalisation de la session sont remplies et que le serveur détermine que les conditions prédéterminées de finalisation de la session de messagerie vocale instantanée à interaction homme-machine sont remplies. Le procédé et le serveur de cette invention permettent d'éviter que des personnes ne puissent participer à la session correctement tout en évitant efficacement la perte de ressources de session du système de communication à multiples abonnés.
