Abstract

An apparatus for reporting location information reports location information to a base station when there is a reporting request for location information necessary for wireless location measurement from the base station and reports the location information necessary for the wireless location measurement to the base station according to a reporting period. In addition, the apparatus for reporting location information reports the location information to the base station when events are generated within the reporting period.

Claims

1. A method for reporting location information for wireless location measurement to a base station from a terminal, the method comprising:

reporting the location information to the base station according to a reporting period; and

reporting the location information to the base station when events are generated within the reporting period.

2. The method of claim 1, wherein an event is generated when position a variation of the terminal exceeds a threshold.

3. The method of claim 1, wherein an event is generated when a distance between a current location and a final reporting location exceeds a threshold.

4. The method of claim 1, further comprising:

receiving a request for the location information through a location based service (LBS) request message from the base station; and

reporting the location information to the base station in response to the LBS request message.

5. The method of claim 4, wherein the LBS request message includes the reporting period.

6. The method of claim 4, wherein the LBS request message includes an indicator that indicates a wireless location measurement type of the base station.

7. The method of claim 1, further comprising:

receiving a request for the location information through a mobile paging advertisement message from the base station; and

reporting the location information to the base station in response to the mobile paging advertisement message.

8. The method of claim 7, wherein the mobile paging advertisement message includes the reporting period.

9. The method of claim 7, wherein the mobile paging advertisement message includes an indicator that indicates a wireless location measurement type of the base station.

10. The method of claim 1, wherein the location information includes a location measuring parameter.

11. The method of claim 10, wherein the location measuring parameter includes at least one of cell ID information, a round trip delay, a relative delay, a received signal strength indicator (RSSI), a carrier to interface ratio, a time of arrival, an angle of arrival, and a time difference of arrival.

12. A method of reporting location information for wireless location measurement to a base station from a terminal, the method comprising:

receiving a message that requests location information from the base station;

reporting the location information to the base station in response to the message;

periodically reporting the location information to the base station according to a reporting period; and

reporting the location information to the base station when a variation of the location information exceeds a threshold within the reporting period.

13. The method of claim 12, wherein the message includes an indicator that indicates a wireless location measurement type of the base station.

14. The method of claim 13, wherein the message includes a location based service (LBS) request message.

15. The method of claim 13, wherein the message includes a mobile paging advertisement message.

16. An apparatus for reporting location information for wireless location measurement to a base station from a terminal, the apparatus comprising:

a condition confirming unit configured to specify a reporting period and an event generating condition; and

an information reporting unit configured to send the location information to the base station according to the reporting period and report the location information to the base station when an event is generated according to the event generating condition.

17. The apparatus of claim 16, wherein the event is generated when a variation between current location information and finally reported location information exceeds a threshold.

18. The apparatus of claim 16, wherein the information reporting unit is further configured to send the location information to the base station in response to a request for the location information from the base station.

19. The apparatus of claim 18, wherein the request for the location information is received through at least one of a location based service (LBS) request message and a paging advertisement message, and wherein each of the LBS request message and the paging advertisement message includes an indicator that indicates a wireless location measurement type of the base station.

20. The apparatus of claim 19, wherein each of the LBS request message and the paging advertisement message further includes the reporting period.
