Abstract

L'invention porte sur un procédé de mise à jour de liste, sur une unité de gestion de mobilité, sur un équipement utilisateur (UE) et sur un nœud B de rattachement (HNB). Le procédé de mise à jour de liste susmentionné est utilisé pour mettre à jour une liste d'identité (ID) de groupe d'abonnés fermé (CSG) autorisée de l'équipement utilisateur dans l'état de connexion. Ledit équipement utilisateur accède au HNB correspondant au CSG en tant qu'utilisateur temporaire du CSG. Le procédé comprend les étapes suivantes : lorsqu'il est déterminé que le temps de résidence de l'équipement utilisateur au niveau du HNB dépasse un seuil prédéterminé, l'unité de gestion de mobilité informe l'UE de la non disponibilité du CSG susmentionné pour amener l'UE à effacer l'ID correspondant au CSG susmentionné dans la liste d'ID de CSG autorisée d'accès dudit UE. A l'aide de la présente invention, un gaspillage de ressources radio provoqué par une re-sélection de cellule incorrecte de l'équipement utilisateur, une génération de rapport d'accès et une tentative d'accès invalide, et ainsi de suite, pourraient être évités.
