The invention relates to a device at a mobile communication system (10) to, at establishing of connection towards a public data communication network (12), identify mobile users (14). The mobile communication system (10) includes at least one first node (16) for handling of packet switching and charging data, at least one second node (18) for establishing of connection to public data communication networks (12) and transmission/mediation of addresses. The communication system (10) in addition includes a third node (22) connected to said first node/nodes (16) and to said second node/nodes (18) for filtering and duplication of modified call detail data records, at which each call detail data record includes a connection between an address and a subscriber. The third node (22) distributed the modified call detail data records to one to the third node (22) connected first memory device (24), at which a mobile user (14) is identified by means of the first memory device (24) and one to said first node/nodes (16) connected second memory device (26) which stores subscriber information. |
