With optimized routing, a lower signaling load and a shorter connection setup time compared to the known two-stage location inquiry is achieved in that the home register (HLRB), even when receiving the message (SRIL) for the location inquiry, the feasibility of establishing the direct connection between the access mobile switching center (GMSCA). of a first network (IPLMN) and visitor mobile switching center (VMSCB) of another network (VPLMN) checked for the sake of charging the call and, if the result of the test is positive, a modified message in which an identifier (PRN) for requesting a temporary residence number (MSRN) is sent to the Visitor Register (VLRB). As a result, the home register can carry out the feasibility of establishing the connection for the sake of charging the call and immediately - i.e. without waiting for another access query by the access mobile switching center - retrieve the residence number from the responsible visitor register and send it to the requesting access mobile switching center. <IMAGE>
