Abstract

La présente invention concerne un procédé de mise en œuvre, un système et un nœud mobile permettant d'accéder à un agent domestique statique (HA). Un dispositif de réseau notifie un nœud mobile de l'adresse du Protocole Internet (IP) de son agent domestique statique et de l'indication d'agent domestique statique, l'adresse IP dudit agent domestique statique étant stockée dans le nœud mobile; lorsque le nœud mobile initie à nouveau la connexion, il peut établir directement une association de sécurité et une relation de liaison avec l'agent domestique statique, conformément à l'adresse IP stockée de l'agent domestique statique. Ceci empêche ainsi le processus de réalisation d'une transformation HA ou de requête d'adresse IP du HA lorsque le nœud mobile se connecte de nouveau au réseau. Ainsi, la charge du réseau et de l'équipement utilisateur est diminuée, ce qui permet d'accélérer la vitesse d'accès à un service par l'équipement utilisateur.
