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-R5) 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-R6) instead of a switching device address (MAP (MSC/SGSN)) in an answer (Ack (MSC(SGSN)) if the request is a request from a version (R5) of a location request treatment device wherein said version (R5) includes provision such that the location request treatment device (GMLC-R5) receives switching device data (MAP(MSC/SGSN) from the subscriber data base (HLR) as an answer.

Claims

1. A method for handling a location data request or location request relating to a subscriber in a mobile radio network, comprising:

upon receipt of a request from a first location request handling device at a subscriber database of a mobile radio network, switching device address data of a switching device, via which the subscriber can currently be reached;

instead of switching the device address data, specifying, via the subscriber database, to the first location request handling device in a response location request handling device address data representing the address of a further location request handling device; and

if it is a request from the location request handling device of a version, according to which version there is provision for the location request handling device to receive switching device address data from the subscriber database as a response.

2. The method according to claim 1, wherein the further location request handling device is a location request handling device in a home network of the subscriber.

3. The method according to claim 1, wherein the further location request handling device stores profile data of the subscriber, which specifies whether and under what conditions the location request relating to the subscriber should be processed and/or responded to.

4. The method according to claim 1, wherein the first older version location request handling device sends the request to the subscriber database after it receives a request from an LCS client.

5. The method according to claim 1, wherein the first location request handling device sends the location request to the address of the further location request handling device, which forwards it to the address of a switching device, which was specified thereto by the subscriber database in response to its request to the subscriber database.

6. The method according to claim 4, wherein the request includes data of the subscriber to be located identifying the subscriber.

7. The method according to one claim 1, wherein the location request handling device address data has a same format as switching device address data.

8. The method according to claim 1, wherein the version of the location request handling device is identified by the subscriber database from the non-extended format of the request.

9. The method according to claim 1, wherein the version of the location request handling device is identified from a Lh interface used.

10. The method according to claim 1, wherein the further location request handling device profile data of the subscriber, in respect of whom a location request is to be implemented, is verified and the further location request handling device contacts the switching device specified to it, if the profile data of the subscriber shows that the location request relating to the subscriber should be carried out.

11. A device for handling a location data request or location request relating to a subscriber in a mobile radio network, comprising:

a subscriber database of a mobile radio network for switching device address data of a switching device, on receipt of a request from a first location request handling device, via which the subscriber can currently be reached; and

a response location request handling device, instead of switching device address data the subscriber database specifies to the first location request handling device, to address data representing the address of a further location request handling device, wherein

if it is a request from a location request handling device of a version, according to which version there is provision for the location request handling device to receive switching device address data from the subscriber database as a response.
