Positioning a subscriber terminal in a packet-switched mobile telephony network using both packet-switched and circuit-switched messages

The object of the invention is a method, network element, and system for positioning a subscriber terminal in a packet-switched mobile telephone network, the said network comprising a core network element (SGSN, 504 ), base stations, a Base Station Controller ( 501 ) controlling these, and a mobile terminal; the connections in the mobile telephone network are arranged in a packet-switched fashion. The system comprises a location unit (SMLC, 505 ) for determining the position of the terminal, functionally connected with the Base Station Controller ( 501 ) of the mobile telephone network; the connection between the Base Station Controller ( 501 ) and the location unit (SMLC) is circuit-switched. The base station controller ( 501 ) comprises both circuit-switched (BSC) and packet-switched (PCU) functionality for processing circuit-switched, and respectively, packet-switched messages, as well as means ( 506, 507 ) for establishing an association between the circuit-switched and the packet-switched functionality for the transmission of data related to a specific positioning between the packet-switched and the circuit-switched functionality.
