Abstract

A method and apparatus for calculating a location of a User Equipment (UE) that is roaming, the method comprising establishing a positioning session with a Home Location Platform (HLP) by using a location request message including specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE, and exchanging positioning information with the HLP to calculate a position of the UE, wherein the position of the UE is determined by the HLP using the exchanged positioning information and approximate coordinate information transmitted from a Visiting Location Platform (VLP) to the HLP. According to such a method, it is possible to efficiently perform the positioning of the UE, regardless of the location of the UE, thereby improving the quality of the positioning service.

Claims

1. A method for calculating a location of a User Equipment (UE) that is roaming, the method comprising:

establishing a positioning session with a Home Location Platform (HLP) by using a location request message including specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE; and

exchanging positioning information with the HLP to calculate a position of the UE, wherein the position of the UE is determined by the HLP using the exchanged positioning information and approximate coordinate information transmitted from a Visiting Location Platform (VLP) to the HLP.

2. The method as claimed in claim 1, wherein exchanging the positioning information with the UE comprises exchanging the positioning information with the UE using a Mobile Station (MS)-Assisted scheme.

3. The method as claimed in claim 1, wherein exchanging the positioning information with the UE comprises exchanging the positioning information with the UE using a Mobile Station (MS)-Based scheme.

4. The method as claimed in claim 1, wherein the positioning scheme includes at least one of a Mobile Station (MS)-Assisted scheme and an MS-Based scheme.

5. The method as claimed in claim 1, further comprising ending the positioning session with the UE, when a position calculation is completed in the HLP.

6. A method for calculating a location of a User Equipment (UE) that is roaming, the method comprising:

establishing a positioning session with a Home Location Platform (HLP) by using a location request message including specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE; and

exchanging positioning information with the HLP to calculate a position of the UE, wherein the position of the UE is determined by a Visiting Location Platform (VLP) using the exchanged positioning information and an approximate coordinate information transmitted from the VLP to the HLP.

7. The method as claimed in claim 6, wherein exchanging positioning information with the UE is performed using a Mobile Station (MS)-Assisted scheme.

8. The method as claimed in claim 6, wherein exchanging positioning information with the UE is performed using a Mobile Station (MS)-Based scheme.

9. The method as claimed in claim 6, wherein the positioning scheme includes at least one of a Mobile Station (MS)-Assisted scheme and a MS-Based scheme.

10. The method as claimed in claim 6, further comprising ending the positioning session with the HLP, when a position calculation is completed in the VLP.

11. A User Equipment (UE) for calculating UE, the UE comprising:

a controller configured to establish a positioning session with a home location platform (HLP) by using a location request message including specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE; and

a transceiver configured to exchange positioning information with the HLP to calculate a position of the UE, wherein the position of the UE is determined by the HLP using the exchanged positioning information and approximate coordinate information transmitted from a Visiting Location Platform (VLP) to the HLP.

12. The UE as claimed in claim 11, wherein exchanging the positioning information with the UE is performed using a Mobile Station (MS)-Assisted scheme.

13. The UE as claimed in claim 11, wherein exchanging the positioning information with the UE is performed using a Mobile Station (MS)-Based scheme.

14. The UE as claimed in claim 11, wherein the positioning scheme includes at least one of a Mobile Station (MS)-Assisted scheme and an MS-Based scheme.

15. The UE as claimed in claim 11, wherein the controller ends the positioning session with the UE, when a position calculation is completed in the HLP.

16. A User Equipment (UE) for calculating UE, the UE comprising:

a controller configured to establish a positioning session with a Home Location Platform (HLP) by using a location request message including specific identifier information of an area in which the UE is located, and positioning capability information including a positioning scheme supported by the UE; and

a transceiver configured to exchange positioning information with the HLP to calculate the position of the UE, wherein the position of the UE is determined by a Visiting Location Platform (VLP) using the exchanged positioning information and an approximate coordinate information transmitted from the VLP to the HLP.

17. The UE as claimed in claim 16, wherein exchanging positioning information with the UE is performed using a Mobile Station (MS)-Assisted scheme.

18. The UE as claimed in claim 16, wherein exchanging positioning information with the UE is performed using a Mobile Station (MS)-Based scheme.

19. The UE as claimed in claim 16, wherein the positioning scheme includes at least one of a Mobile Station (MS)-Assisted scheme and an MS-Based scheme.

20. The UE as claimed in claim 16, wherein the controller ends the positioning session with the HLP, when a position calculation is completed in the VLP.
