CA 2336621

The present invention relates to a telecommunication system, a method for setting-up a call in a telecommunication system and switching means in a telecommunication system for providing a call between a first subscriber station and a second subscriber station. A second subscriber station sends a request for obtaining location information concerning the first subscriber station to the telecommunication system. Then, location information is extracted from network information already available in the mobile radio telecommunication network to which the first subscriber station is connected by means of location information extracting means. The extracted location information is provided to the second subscriber station by means of location information providing means. Since no radio path is established to said first mobile subscriber station in question the resource consumption for providing location information can be minimized.

L'invention suivante concerne un système de télécommunication, une méthode pour configurer un appel et les moyens de commutation instituant un appel entre deux postes d'abonné dans un système de communication. Un deuxième poste d'abonné envoie une requête pour obtenir l'information de position du premier poste d'abonné au système de télécommunicaton. Puis, l'information de position est extraite de l'information de réseau déjà disponible sur le réseau de radio télécommunication mobile auquel est connecté le premier poste d'abonné, par des méthodes d'extraction d'information de position. L'information de position extraite est fournie au deuxième poste d'abonné par des méthodes de divulguation d'information de position. Puisque aucun chemin radio n'est établi vers ledit premier poste d'abonné mobile en question, la consommation de ressource pour fournir l'information de position peut être minimisée.
