Abstract

Techniques are disclosed for enabling wireless communication with the capability of modifying assistance data and/or location information. A first transaction is used to define location related data for transferring between a location server and a mobile device. A second transaction is used to transfer the location related data between the location server and the mobile device. A third transaction is used to modify the location related data for transferring between the location server and the mobile device.

Claims

1. A method of determining a location of a mobile device, comprising;

identifying a confirmed type of location related data for transferring between a location server and the mobile device using a first transaction, wherein the first transaction includes;

a message identifying a requested type of location related data, and

a response to the message, identifying the confirmed type of location related data in a 3GPP LTE Positioning Protocol (LPP) Extensions message, wherein information carried in the LPP Extensions (LPPe) message is used to support transfer of assistance data and location information according to defined LPP and LPPe procedures;

wherein the message and the response both include;

a first transaction identifier, and

a session identifier; and

transferring location related data of the confirmed type between the location server and the mobile device using a second transaction, wherein the second transaction includes;

a second transaction identifier, and

the same session identifier as the first transaction;

wherein the first and second transactions are LPP transactions communicated in accordance with LPP.

2. The method of claim 1, further comprising modifying at least one of the type of location related data, periodicity for transferring data, triggering criteria, or termination condition using a third transaction, wherein the third transaction is an LPP transaction communicated in accordance with 3GPP LTE Positioning Protocol (LPP).

3. The method of claim 1, in which the location related data is assistance data transferred from the location server to the mobile device.

4. The method of claim 1, in which the location related data is location information transferred from the mobile device to the location server.

5. The method of claim 2, in which modifying comprises sending an update request from the mobile device to the location server.

6. The method of claim 2, in which modifying comprises sending an update request from the location server to the mobile device.

7. The method of claim 1, in which the first and second transaction identifiers are distinct LPP transaction IDs.

8. The method of claim 2, in which the third transaction uses an LPP transaction ID different from an LPP transaction ID used by the second transaction.

19. The method of claim 1, wherein the confirmed type of location related data is the same as the requested type of location related data.

9. An apparatus for wireless communication, comprising:

a memory; and

at least one processor coupled to the memory, the at least one processor being configured to;

identify a confirmed type of location related data for transferring between a location server and a mobile device using a first transaction, wherein the first transaction includes;

a message identifying a requested type of location related data, and

a response to the message, identifying the confirmed type of location related data in a 3GPP LTE Positioning Protocol (LPP) Extensions message, wherein information carried in the LPP Extensions (LPPe) message is used to support transfer of assistance data and location information according to defined LPP and LPPe procedures;

wherein the message and the response both include;

a first transaction identifier, and

a session identifier; and

transfer location related data of the confirmed type between the location server and the mobile device using a second transaction, wherein the second transaction includes;

a second transaction identifier, and

the same session identifier as the first transaction;

wherein the first and second transactions are LPP transactions communicated in accordance with LPP.

10. The apparatus of claim 9, in which the at least one processor is further configured to modify at least one of the type of location related data, periodicity for transferring data, triggering criteria and termination condition using a third transaction, wherein the third transaction is an LPP transaction communicated in accordance with 3GPP LTE Positioning Protocol (LPP).

11. The apparatus of claim 9, in which the location related data is assistance data transferred from the location server to the mobile device.

12. The apparatus of claim 9, in which the location related data is location information transferred from the mobile device to the location server.

13. The apparatus of claim 10, in which the at least one processor configured to send an update request from the mobile device to the location server.

14. The apparatus of claim 10, in which the at least one processor configured to send an update request from the location server to the mobile device.

15. The apparatus of claim 9, in which the first and second transaction identifiers are distinct LPP transaction IDs.

16. The apparatus of claim 10, in which the third transaction uses an LPP transaction ID different from the second transaction identifier.

17. A computer program product for wireless communication in a wireless network, comprising:

a computer-readable medium having non-transitory program code recorded thereon, the program code comprising;

program code to identify a confirmed type of location related data for transferring between a location server and a mobile device using a first transaction, wherein the first transaction includes;

a message identifying a requested type of location related data, and

a response to the message, identifying the confirmed type of location related data in a 3GPP LTE Positioning Protocol (LPP) Extensions message, wherein information carried in the LPP Extensions (LPPe) message is used to support transfer of assistance data and location information according to defined LPP and LPPe procedures;

wherein the message and the response both include;

a first transaction identifier, and

a session identifier; and

program code to transfer location related data of the confirmed type between the location server and the mobile device using a second transaction, wherein the second transaction includes;

a second transaction identifier, and

the same session identifier as the first transaction;

wherein the first and second transactions are LPP transactions communicated in accordance with LPP.

18. An apparatus for wireless communication, comprising:

means for identifying a confirmed type of location related data for transferring between a location server and a mobile device using a first transaction, wherein the first transaction includes;

a message identifying a requested type of location related data, and

a response to the message, identifying the confirmed type of location related data in a 3GPP LTE Positioning Protocol (LPP) Extensions message, wherein information carried in the LPP Extensions (LPPe) message is used to support transfer of assistance data and location information according to defined LPP and LPPe procedures;

wherein the message and the response both include;

a first transaction identifier, and

a session identifier; and

means for transferring location related data of the confirmed type between the location server and the mobile device using a second transaction, wherein the second transaction includes;

a second transaction identifier, and

the same session identifier as the first transaction;

wherein the first and second transactions are LPP transactions communicated in accordance with LPP.
