Abstract

L'invention concerne un procédé pour la prise en charge de mobilité de connexion de déchargement du protocole Internet (IP). Le procédé comprend les étapes suivantes : lorsqu'un terminal se déplace, un élément de réseau du côté sans fil desservant actuellement le terminal évalue la mobilité de connexion de déchargement IP du terminal selon les informations de détermination de mobilité obtenues, conservant la connexion de déchargement IP du terminal lorsqu'il est déterminé que la connexion de déchargement IP du terminal prend en charge la mobilité, et libérant la connexion de déchargement IP du terminal lorsqu'il est déterminé que la connexion de déchargement IP ne prend pas en charge la mobilité. L'invention concerne également un système pour la prise en charge de mobilité de connexion de déchargement IP. Par l'utilisation du procédé et du système de l'invention, la fréquence d'interruption de la connexion de déchargement IP due au mouvement du terminal est diminuée, améliorant ainsi l'expérience de l'utilisateur.
