Abstract

La présente invention concerne un procédé pour commander de manière centralisée le service d'implémentation d'appel de terminal dans un sous-système de réseau central multimédia de protocole internet (IMS), comprenant les étapes suivantes : ICCF appelle l'équipement utilisateur (UE) auquel il a eu accès par le circuit commuté (CS) par l'intermédiaire du chemin de commande de session et transporte son adresse ICCF attribuée après avoir reçu la requête d'appel de terminal initié par le côté appelant ; l'UE initie l'appel CS en utilisant l'adresse ICCF comme numéro appelé et établit la connexion entre l'UE et l'ICCF pour implémenter l'établissement d'un chemin de commande porteur ; et l'appel de terminal est implémenté en utilisant le chemin de commande porteur. Cette invention peut établir le chemin de commande porteur sans que l'ICCF attribue le numéro d'itinérance. Il s'agit d'un procédé qui peut résoudre efficacement l'appel de terminal ICS.
