The method involves evaluating signals a base station subsystem sends and determining the identification of the base station subsystem. The set up, dismantling and changes to one or more virtual connections (BVC) are detected based on the evaluation and determination. If this detection cannot be performed in this way, a comparison is made with existing information relating to one more virtual connections. Virtual connections that are to be set up, dismantled or changed are identified based on the informati obtained by the evaluation, determination, detection and comparison. The method then involves erasing, storing or updating information relating to the virtual connections that contain information identifying those base station subsystems participating the virtual connection and identifying a routing area (RA) in which a cell participating in the virtual connection lines. An Independent claim is included for an apparatus for a GSM communication system offering a general packet radio service (GPRS). |
