Abstract

La présente invention concerne un procédé de transmission de message par protocole IP à base de protocole de transfert de message. En l'occurrence, après réception du SMS ou MMS encapsulé dans le protocole de communication de messages, la passerelle de messagerie IP du réseau d'accès IP établit une compatibilité avec l'équipement utilisateur IP destinataire. La passerelle de messagerie IP vérifie que l'équipement utilisateur IP destinataire est compatible avec le protocole de communication de messages conformément aux compatibilités définies pour l'équipement utilisateur IP destinataire. Si c'est le cas, la passerelle transmet à l'équipement utilisateur IP destinataire le SMS ou MMS encapsulé dans le protocole de communication de message. A cet effet, elle le transporte dans le message en utilisant le protocole IP à base de protocole de transfert de message. Si ce n'est pas le cas, la passerelle prend le contenu du SMS ou MMS encapsulé dans le protocole de communication de message, et transmet à l'équipement utilisateur IP destinataire le contenu du message. A cet effet, elle le transporte dans le message en utilisant le protocole IP à base de protocole de transfert de message.
