Abstract
At least one virtual location area identifier (SG-LAC) that does not correspond to any of the location area identifiers for real location areas in the mobile radiotelephone network is allocated to a packet data service network node (SGSN) with which a packet data service is controlled in the mobile radiotelephone network for the transmission of one or more data packets. This is employed by a mobile switching center for the implementation of the functions in the location area management. As a result thereof, a common and efficient management of location areas (locations areas, routing areas) can be achieved upon involvement of the packet data service in the cellular mobile radiotelephone network without the standard interfaces and procedures for the mobile switching center having to be modified for this purpose.
