A method uses inter-base station control messages to provide neighbor base station information to mobile subscriber stations in a mobile communication system. The method includes obtaining (S414, S415), at a serving base station, physical channel information of neighbor base stations over a backbone network via, either directly or via a server; periodically transmitting (S417) the obtained physical channel information from the serving base station to a mobile subscriber station connected to the serving base station; and measuring, based on the updated physical channel information, signal quality of the at least one neighbor base station at the mobile subscriber station. Thus, the serving base station receives from the neighbor base stations the inter-base station control messages containing the neighbor base station information, updates the information, and provides the updated information to the corresponding mobile subscriber station(s), to be used for a specific purpose such as handover or network entry.

La présente invention concerne un procédé qui utilise des messages de commande entre stations de base pour fournir des informations de stations de base voisines à des stations d'abonné mobile dans un système de communication mobile. Ce procédé consiste à obtenir au niveau d'une station de base de desserte des informations de canal physique de stations de base voisines sur un réseau de base soit directement, soit via un serveur, à transmettre périodiquement les informations de canal physique obtenues de la station de base de desserte à une station d'abonné mobile reliée à la station de base de desserte, puis à mesurer, sur la base des informations de canal physique mises à jour, une qualité de signal de la station de base voisine au niveau de la station d'abonné mobile. La station de base de desserte reçoit ainsi des stations de base voisines les messages de commande entre stations de base contenant les informations de stations de base voisines, met à jour ces informations, puis fournit les informations mises à jour à la/aux stations d'abonné mobile correspondante(s) afin qu'elle(s) les utilise(nt) à des fins spécifiques, telles qu'un transfert ou un accès au réseau.
