The invention relates to a device for a GSM (Global System for Mobile Communication) communication system offering a GPRS (General Packet Radio Service), for determining the base station subsystems involved in a paging on a routing area level. Moreover, the invention relates to a method for setting up and/or updating the device. The set-up and/or the update of the device takes place in a GPRS service node, for example, after the receipt of a message on a set-up, a release or a modification of virtual connections. For this purpose the information contained in the message are evaluated and compared with already existing information. Another possibility is the evaluation of information in data packets, which, too, are compared with already existing information. Subsequently the information is, if required, updated and stored. In the case of a paging on a routing area level the stored information is used for communicating the signaling addresses of base station subsystems, which supply the routing area, to a GPRS service node. The information is also used for detecting as to which routing areas are supplied by a GPRS service node.
