Abstract

La présente invention a pour objet un procédé consistant à transmettre une communication d'une mise hors tension d'un utilisateur avec un service centralisé de sous-système multimédia IP (IMS). Il comprend les étapes suivantes : le centre de commutation mobile visité (VMSC) (102) trouve la mise hors tension de l'utilisateur appelé, transmet ensuite le message de réponse d'erreur d'une partie d'application mobile (MAP) comprenant la valeur de la raison de la mise hors tension de l'utilisateur appelé à l'unité de fonction de commande à commutation de circuit IMS (ICCF) (106) après que l'unité ICCF (106) a transmis le message de demande d'appel commuté au VMSC (102) ; l'unité ICCF (106) mappe le message de réponse d'erreur MAP sur le message de réponse du protocole d'ouverture de session (SIP) comprenant la valeur de la raison de la mise hors tension de l'utilisateur appelé, et transmet le message de réponse SIP au serveur d'application de télécommunication (TAS) (108) ; le TAS (108) commande le déclenchement du service de transmission de communication de la mise hors tension en fonction de la valeur de la raison de l'utilisateur appelé dans le message de réponse SIP. Le jugement de la mise hors tension ou non peut être traité par le serveur d'abonné local (103).
