Abstract: A telecommunication system, a method for setting-up a call in a telecommunication system and a switching device in a telecommunication system for providing a call between a first subscriber station and a second subscriber station is disclosed. 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 a location information extracting device. The extracted location information is provided to the second subscriber station by means of a location information providing device. Since no radio path is established to the first mobile subscriber station in question the resource consumption for providing location information can be minimized.
