Abstract

La présente invention concerne un procédé permettant à des terminaux mobiles d'accéder à un Nœud B domestique ouvert et est destinée à résoudre le problème d'accès à un Nœud B domestique ouvert que tous les terminaux mobiles rencontrent actuellement. Ce procédé comprend les étapes suivantes : un terminal mobile recherche une cellule et se synchronise avec une onde porteuse d'une station de base, reçoit des informations de radiodiffusion correspondant à ladite station de base, puis les analyse et détermine que la station de base est un Nœud B domestique, et envoie alors une demande d'accès à ce Nœud B domestique; le Nœud B domestique détermine le statut de la liste d'abonnés de son propre groupe fermé d'abonnés, si ce statut correspond à une indisponibilité, il détermine que le statut actuel est le mode ouvert, et il fournit directement au terminal mobile le service d'accès au réseau. La présente invention concerne également un système permettant de mettre en œuvre le procédé ci-dessus. L'invention complète le flux d'accès des UE avec le Nœud B domestique ouvert, résout le problème d'accès des terminaux au Nœud B domestique ouvert ainsi que le problème d'accès des UE lorsque le Nœud B domestique ouvert est fermé, complète le procédé d'accès pour terminaux du Nœud B domestique dans le cas du multimode, et élargit le domaine d'application et les fonctions du Nœud B domestique.
