Abstract

L'invention concerne un procédé permettant de fournir des informations concernant l'emplacement d'un abonné à un réseau de radiotélécommunication (10) et un réseau de communication intégré qui incorpore le réseau de radiotélécommunicaton avec au moins un réseau de communication câblée. Lorsqu'un abonné utilise une station mobile (11) pour accéder au réseau de radiotélécommunication, une station de base radio (RBS) (13) envoie à un centre de commutation radiomobile (MSC) (15), une identité cellulaire de la cellule (12) recevant l'enregistrement en provenance de la station mobile. L'identité cellulaire est convertie dans une table de cellule/coordonnées (25) en une plage de coordonnées géographiques qui se rapprochent de la zone de couverture de la cellule. Les coordonnées géographiques sont ensuite envoyées depuis le MSC au réseau de radiotélécommuniation ou à une passerelle (23) pour le réseau de communication intégré via un message d'accès réseau. Les coordonnées peuvent remplacer ou supplanter les informations concernant les cellules dans le message d'accès réseau.
