Abstract

La présente invention concerne un procédé, un serveur et un système de mise en attente d'appels dans un service de central centralisé sur un domaine de sous-système multimédia sous protocole Internet (IMS) , le procédé comportant les étapes suivantes : lorsqu'une session a lieu entre un premier utilisateur et un deuxième utilisateur, un serveur de desserte du central reçoit un premier code de mise en attente émanant du premier utilisateur et suspend la session avec le deuxième utilisateur ; le serveur de desserte du central reçoit un deuxième code de mise en attente émanant d'un troisième utilisateur pour reprendre la session et, si le deuxième code de mise en attente correspond au premier code de mise en attente, le serveur de desserte du central active alors la session entre le deuxième utilisateur et le troisième utilisateur. Dans le schéma, un utilisateur transfère une session à un serveur de desserte du central pour la mise en attente d'appels en composant un code de mise en attente, le serveur de desserte du central place la session en état de suspension et, par la suite, l'utilisateur peut réaliser une connexion sans discontinuité pour reprendre la session en composant le code de mise en attente sur un téléphone quelconque pour reprendre la session. La session au sein d'un groupement peut être mise en attente puis reprise en d'autres lieux, de façon à améliorer le confort de l'utilisateur.
