Abstract
A location-based service is handled for a limited geographic area for a plurality of subscribers in this geographic area. The area is served by more than one device for determining the geographic position of mobile radio users. The location-based service sends an inquiry about the identity of subscribers in the geographic area to a central network element, whereupon the central network element, instead of the location-based service, requests the current information about the subscribers active in the limited geographic area from the at least two devices for determining the geographic position of mobile radio users. The central network element then delivers the result back to the location-based service.
