Abstract

L'invention concerne un procédé et un dispositif de mise à jour de configuration. Le procédé comprend les étapes suivantes : s'il est déterminé qu'une configuration d'un terminal doit être mise à jour, un élément de réseau de gestion de mobilité détermine si un service cible est actuellement exécuté au niveau du terminal, et si tel est le cas, il transmet un message de mise à jour de configuration au terminal et s'abstient de déclencher une procédure de lancement de connexion de signalisation. Du fait que l'élément de réseau de gestion de mobilité ne déclenche pas la procédure de lancement de connexion de signalisation, l'interruption de l'exécution du service cible peut être évitée.
