Abstract

Selon des modes de réalisation, la présente invention concerne un procédé et un système de suppression de configuration, un dispositif terminal et une station de base de desserte. Le procédé comprend les étapes suivantes : une station de base de desserte envoie des informations de configuration d'AUM à un dispositif terminal, et le dispositif terminal sauvegarde les informations de configuration d'AUM qui sont configurées par une première cellule candidate pour le dispositif terminal ; la station de base de desserte envoie au dispositif terminal des informations d'instruction pour supprimer la configuration d'AUM ; et le dispositif terminal supprime, selon les informations d'instruction pour supprimer la configuration d'AUM, les informations de configuration d'AUM qui sont configurées par la première cellule candidate pour le dispositif terminal. Dans les modes de réalisation de la présente invention, lorsque le dispositif terminal doit seulement commuter une fois pour accéder à une cellule cible, les modes de réalisation de la présente invention réduisent le temps nécessaire au dispositif terminal pour accéder à la cellule cible par comparaison avec l'état de la technique.
