Treatment of a location request by a first location request treatment device (a gateway mobile location centre) in a home register (hlr) for retransmission to a second location request treatment device

Abstract

The invention relates to the efficient treatment of location requests by a home register and GMLCs of various versions by means of a method for treating a location request relating to a subscriber in a mobile radio network. Once a request (SRI) from a first location request treatment device (GMLC-R) arrives in a subscriber data bank (HLR) in a mobile radio network, relating to switching device address data (MAP (MSC/SGSN)) in a switching device (MSC/SGSN) or location request treatment device (V-GMLC), enabling (MSC/SGSN/V-GMLC) a subscriber (MS) to be currently reached, the subscriber data bank (HLR) indicates the address (MAP (H-GMLC) of another location request treatment device (H-GMLC-R) instead of a switching device address (MAP (MSC/SGSN)) in an answer (Ack (MSC(SGSN)) if the request is a request from a version (R) of a location request treatment device wherein said version (R) includes provision such that the location request treatment device (GMLC-R) receives switching device data (MAP(MSC/SGSN) from the subscriber data base (HLR) as an answer.
