Abstract

A method for determining whether a terminal is located inside a discovered Secure User Plane Location Platform (D-SLP) service area is disclosed. The method may comprise identifying a discovered Secure User Plane Location Platform (D-SLP). A terminal may receive from a home Secure User Plane Location Platform (H-SLP) an authorization to use the D-SLP. Additionally, the terminal may receive from the H-SLP a list of Area IDs within a Secure User Plane Location Platform (SLP) service area comprises a first group of Area IDs within the SLP service area. The method may comprise comparing an ID associated with a network access point for the terminal, and the list of Area IDs to determine if the terminal is inside the D-SLP service area. The method may comprise making a D-SLP use determination based on the comparison.

Claims

1. A method for determining whether a terminal is located inside a discovered Secure User Plane Location Platform (D-SLP) service area, the method comprising:

identifying a D-SLP;

receiving, at the terminal, from a home Secure User Plane Location Platform (H-SLP) an authorization to use the D-SLP;

receiving, at the terminal from the H-SLP, a list of Area IDs within a Secure User Plane Location Platform (SLP) service area comprising a first group of Area IDs within the SLP service area;

comparing an ID associated with a network access point for the terminal, and the list of Area IDs to determine if the terminal is inside the D-SLP service area; and

making a D-SLP use determination based on the comparison.

2. The method of claim 1, wherein the ID associated with the network access point for the terminal includes a cell, sector, or access point ID that the terminal is active or idle on.

3. The method of claim 1, wherein the determination is to use the D-SLP if the ID associated with the network access point for the terminal is included in the first group of Area IDs.

4. The method of claim 1, wherein the list of Area IDs further comprises a second group of Area IDs on a border of the SLP service area.

5. The method of claim 4, further comprising:

engaging in precise location positioning to determine whether the terminal is inside the D-SLP service area if the ID associated with the network access point is included in the second group of Area IDs; and

making a D-SLP use determination based on the precise location positioning result.

6. The method of claim 4, wherein the determination is to not use the D-SLP if the ID associated with the network access point for the terminal is not included in neither the first group nor the second group of Area IDs.

7. The method of claim 1, wherein the list of Area IDs are received using a SUPL END message.

8. The method of claim 1, wherein the determination is repeated until a predetermined trigger, wherein the predetermined trigger causes the terminal to stop using the D-SLP.

9. The method of claim 8, wherein if the predetermined trigger occurs, the terminal must receive a second authorization from the H-SLP for further access to the D-SLP.

10. The method of claim 8, wherein the predetermined trigger is based on ending a service privilege of the terminal with the D-SLP.

11. The method of claim 10, wherein the ending of the service privilege is based on an end of a time period, an end of a certain use of time, a threshold number of hours used, or a withdrawal of service message from the H-SLP.

12. A terminal comprising:

one or more processors; and

memory storing computer-readable instructions that, when executed by the one or more processors, cause the terminal to;

identify a discovered Secure User Plane Location Platform (D-SLP);

receive, at the terminal, from a home Secure User Plane Location Platform (H-SLP) an authorization to use the D-SLP;

receive at the terminal from the H-SLP, a list of Area IDs within a Secure User Plane Location Platform (SLP) service area comprising a first group of Area IDs within the SLP service area;

compare an ID associated with a network access point for the terminal, and the list of Area IDs to determine if the terminal is inside the D-SLP service area; and

make a D-SLP use determination based on the comparison.

13. The terminal of claim 12, wherein the ID associated with the network access point for the terminal includes a cell, sector, or access point ID that the terminal is active or idle on.

14. The terminal of claim 12, wherein the determination is to use the D-SLP if the ID associated with the network access point for the terminal is included in the first group of Area IDs.

15. The terminal of claim 12, wherein the list of Area IDs further comprises a second group of Area IDs on a border of the SLP service area.

16. The terminal of claim 15, further comprising computer-readable instructions that, when executed by the one or more processors, cause the terminal to:

engage in precise location positioning to determine whether the terminal is inside the D-SLP service area if the ID associated with the network access point is included in the second group of Area IDs; and

make a D-SLP use determination based on the precise location positioning results.

17. The terminal of claim 15, wherein the determination is to not use the D-SLP if the ID associated with the network access point for the terminal is not included in neither the first group nor the second group of Area IDs.

18. The terminal of claim 12, wherein the list of Area IDs are received using a SUPL END message.

19. The terminal of claim 12, wherein the determination is repeated until a predetermined trigger, wherein the predetermined trigger causes the terminal to stop using the D-SLP.

20. The terminal of claim 19, wherein if the predetermined trigger occurs, the terminal must receive a second authorization from the H-SLP for further access to the D-SLP.

21. The terminal of claim 19, wherein the predetermined trigger is based on ending a service privilege of the terminal with the D-SLP.

22. The terminal of claim 21, wherein the ending of the service privilege is based on an end of a time period, an end of a certain use of time, a threshold number of hours used, or a withdrawal of service message from the H-SLP.

23. One or more computer-readable media storing computer-executable instructions for determining whether a terminal is located inside a discovered Secure User Plane Location Platform (D-SLP) service area that, when executed, cause one or more computing devices included in the terminal to:

identify a D-SLP;

receive, at the terminal, from a home Secure User Plane Location Platform (H-SLP) an authorization to use the D-SLP;

receive at the terminal from the H-SLP, a list of Area IDs within a Secure User Plane Location Platform (SLP) service area comprising a first group of Area IDs within the SLP service area;
