Abstract

L'invention porte sur un procédé d'intercommunication entre un réseau à séparation du localisateur et de l'identificateur et l'Internet, lequel procédé comprend les opérations suivantes : le réseau à séparation du localisateur et de l'identificateur envoie des paquets de données de réseau à séparation du localisateur et de l'identificateur à une passerelle d'intercommunication, l'adresse de source étant le code d'identité du terminal de réseau à séparation du localisateur et de l'identificateur et l'adresse de destination étant le code d'identité du terminal Internet dans le réseau à séparation du localisateur et de l'identificateur ; la passerelle d'intercommunication reçoit les paquets de données de réseau à séparation du localisateur et de l'identificateur envoyés par le réseau à séparation du localisateur et de l'identificateur, et convertit les paquets de données de réseau à séparation du localisateur et de l'identificateur en paquets de données Internet, ce qui consiste à convertir l'adresse de source en l'adresse IP du terminal de réseau à séparation du localisateur et de l'identificateur dans l'Internet et à convertir l'adresse de destination en l'adresse IP du terminal Internet ; après que les paquets de données ont été convertis, la passerelle d'intercommunication envoie les paquets de données Internet à l'Internet ; et l'Internet reçoit les paquets de données Internet envoyés par la passerelle d'intercommunication. Le procédé d'intercommunication, le réseau d'intercommunication et la passerelle d'intercommunication de l'invention peuvent permettre l'intercommunication entre les réseaux qui adoptent des identificateurs de terminal différents.
