Abstract

A method of providing location information of a target Secure User Plane Location (SUPL) Enabled Terminal (target SET) while protecting privacy of a user of the target SET in a Home-SUPL Location Center (H-SLC) providing the location information of the target SET, and the H-SLC, are provided. The method includes receiving a location request message from a requester, transmitting an SUPL INITiation (SUPL INIT) message by using a first session IDentifier (ID) to the target SET, the first session ID including a real ID of the target SET, transmitting a Positioning DATA (PDATA) message by using a second session ID to the Home-SUPL Positioning Center (H-SPC), the second session ID including a pseudo-ID for secure connection between the H-SLC and the H-SPC, receiving a positioning result of the target SET from the H-SPC, and transmitting the positioning result to the requester.

Claims

1. A method performed by a mobile terminal for receiving location information of the mobile terminal, the method comprising:

transmitting a location request message including an IDentifier (ID) of the mobile terminal to a location server; and

receiving a first message including a first session ID from the location server, the first session ID includes the ID of the mobile terminal,

wherein the location request message is transformed to a second message including a second session ID for an interface with a positioning center for calculating the location information, and the second session ID is different from the first session ID, and

wherein the first message is coarse location information and the method further includes receiving fine location information including the first session ID from the location server.

9. The method of claim 1, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

2. A method performed by a mobile terminal for receiving location information of the mobile terminal, the method comprising:

transmitting a location request message including a real IDentifier (ID) of the mobile terminal to a location server; and

receiving a first message including the real ID from the location server,

wherein the location request message is transformed to a second message including a pseudo ID of the mobile terminal for an interface with a positioning center for calculating the location information, and

wherein the first message is coarse location information and the method further includes receiving fine location information including the real ID from the location server.

10. The method of claim 2, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

3. A mobile terminal, comprising:

a controller which generates a location request message including an IDentifier (ID) of the mobile terminal; and

a transceiver which transmits the location request message to a location server and receives a first message including a first session ID from the location server,

wherein the location request message is transformed to a second message including a second session ID for an interface with a positioning center for calculating the location information, and the second session ID is different from the first session ID, and

wherein the first message is coarse location information and the transceiver further receives fine location information including the first session ID from the location server.

11. The mobile terminal of claim 3, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

4. A mobile terminal, comprising:

a controller which generates a location request message including an real IDentifier (ID) of the mobile terminal; and

a transceiver which transmits the location request message to a location server and receives a first message including the real ID from the location server,

wherein the location request message is transformed to a second message including a pseudo ID of the mobile terminal for an interface with a positioning center for calculating the location information, and

wherein the first message is coarse location information and the transceiver further receives fine location information including the real ID from the location server.

12. The mobile terminal of claim 4, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

5. A method performed by a location server for providing location information of the mobile terminal, the method comprising:

receiving a location request message based on a first session ID from a mobile terminal, the first session ID includes the ID of the mobile terminal;

transmitting a first message based on a first session ID to the mobile terminal; and

transmitting a second message based on a second session ID to a positioning center for calculating the location information, the second session ID being different from the first session ID,

wherein the first message is coarse location information and the method further includes transmitting fine location information including the first session ID to the mobile terminal.

13. The method of claim 5, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

6. A method performed by a location server for providing location information of the mobile terminal, the method comprising:

receiving a location request message including an real IDentifier (ID) of the mobile terminal from a mobile terminal;

transmitting a first message based on the real ID to the mobile terminal; and

transmitting a second message based on a pseudo ID of the mobile terminal to a positioning center for calculating the location information,

wherein the first message is coarse location information and the method further includes transmitting fine location information including the first session ID to the mobile terminal.

14. The method of claim 6, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

7. A location server comprising:

a transceiver which receives a location request message based on a first session ID from a mobile terminal, the first session ID includes the ID of the mobile terminal; and

a controller which generates a first message based on the first session ID and a second message based on a second session ID, the second session ID is different from the first session ID,

wherein the transceiver further transmits the first message to the mobile terminal and the second message to a positioning center for calculating the location information, and

wherein the first message is coarse location information and the transceiver further transmits fine location information including the first session ID to the mobile terminal.

15. The location server of claim 7, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.

8. A location server comprising:

a transceiver which receives a location request message including an real IDentifier (ID) of the mobile terminal from a mobile terminal; and

a controller which generates a first message based on the real ID and a second message based on a pseudo ID of the mobile terminal, the second session ID is different from the first session ID,

wherein the transceiver further transmits the first message to the mobile terminal and the second message to a positioning center for calculating the location information, and

wherein the first message is coarse location information and the transceiver further transmits fine location information including the first session ID to the mobile terminal.

16. The location server of claim 8, wherein the location request message further includes at least one of a positioning capability of the mobile terminal, a cell ID and a quality of position.
