Abstract

La présente invention concerne un procédé et un système d'acheminement et d'adressage de message court. Après avoir reçu le message court, qui est envoyé depuis le centre du service de messages courts (SMSC) à l'identité non enregistrée du domaine IMS (sous-système multimédia IP), le noeud passerelle pour messages courts interroge l'unité de l'enregistreur de position nominale (HLR) pour connaître l'adresse de passerelle de messages courts IP (IP-SM-GW) se rapportant à l'identité non enregistrée. Le noeud passerelle pour messages courts achemine le message court à l'IP-SM-GW. Après réception du message court, l'IP-SM-GW exécute l'adressage à destination du serveur d'applications (AS) hébergeant l'identité non enregistrée dans le domaine IMS et réachemine le message court à l'AS. Ce procédé et ce système permettent de résoudre de façon efficace le problème de l'acheminement et de l'adressage du message court à destination du serveur d'applications dans le domaine IMS. Ce procédé et ce système peuvent réaliser la procédure d'interaction entre utilisateur et serveur d'application avec message court, et la procédure de communication de messages courts entre l'utilisateur dans le domaine CS et l'identité non enregistrée dans le domaine IMS.
