Abstract

L’invention concerne une méthode et un système de réalisation d’un service de messages de zone de réseau basé sur IP revenant, pour l’essentiel, à définir les informations d’adresse du côté récepteur de service de messages de préréglage de zone de réseau basé sur IP appelant/appelée. L’IP-Message-GW de la zone de réseau basé sur IP acquiert les informations d’adresse du côté récepteur de service de messages, l’IP-Message-GW transmet le message reçu au côté récepteur de service de messages en fonction des informations d’adresse acquises. L’invention concerne également deux systèmes de réalisation d’un service de messages de zone de réseau basé sur IP. L’IP-Message-GW de la présente invention n’a pas besoin d’analyser les informations d’adresse de centre de service de messages courts de zone de réseau basé sur IP, tel un réseau IMS, d’entité de message de message. La présente invention permet au message de satisfaire au format de signalisation SIP de message en accord avec les habitudes d’utilisation des utilisateurs de zone de réseau IMS, réduisant la longueur d’occupation de l’entité de message. On obtient, en accord, l’amélioration de l’activité de réalisation du service de messages et un progrès du développement de l’interaction de services de messages.
