Abstract

A method and apparatus for providing an alert on a portable communication device such as a user equipment (UE) entering an alerting area is provided. The UE runs a GPS engine continuously to estimate the location of the UE from the time the alert system is activated. The method and apparatus provide an alert system on a UE by calculating the distance between the UE and alerting area. Further, the method and apparatus enable using different positioning systems based on the distance of the UE from the alerting area, thereby reducing the power consumption of the UE battery.

Claims

1. A method for providing an alert on a user equipment (UE) entering an alerting area, the method comprising:

calculating a distance between location of the UE and the alerting area;

calculating position of the UE using an alternate positioning method, if the calculated distance is greater than or equal to a predetermined distance threshold; and

calculating position of the UE using a satellite based communication method, if the calculated distance is less than the distance threshold.

2. The method as claimed in claim 1, wherein the location of the UE is calculated using GPS, if the calculated distance is less than the distance threshold.

3. The method as claimed in claim 1, wherein an alerting system is activated by a user of the UE.

4. The method as claimed in claim 1, wherein the alternate positioning method is at least one of a cell-ID based positioning system, Wi-Fi positioning system, and Observed Time Difference of Arrival (OTDA) positioning system.

5. The method as claimed in claim 4, wherein the cell-ID based positioning system is at least one of a Secure User Plane Location (SUPL) protocol based cell-ID positioning system, cell-ID in control plane based positioning system, and enhanced cell-ID.

6. The method as claimed in claim 4, wherein the cell-ID based positioning system gives priority to umbrella cells over micro cells, macro cells and pico cells.

7. The method as claimed in claim 6, further comprising storing at least one of cell IDs, location of the cell IDs, and priority of cells corresponding to the cell IDs in a database.

8. The method as claimed in claim 1, wherein the satellite based communication method is at least one of Global Positioning System (GPS), and Assisted GPS (AGPS).

9. The method as claimed in claim 1, wherein further comprising calculating location of the UE using GPS at periodic intervals, if the calculated distance is greater than or equal to a predetermined second threshold.

10. The method as claimed in claim 9, wherein the periodic intervals depend on at least one of speed of the UE, direction of travel of the UE with respect to the alerting area, and distance of the UE from the alerting area.

11. An apparatus for providing an alert on a user equipment (UE) entering an alerting area, the apparatus comprising:

a calculator to calculate a distance between location of the UE and the alerting area; and

an algorithm selection unit to calculate position of the UE using an alternate positioning method, if the calculated distance is greater than or equal to a predetermined distance threshold, and to calculate position of the UE using a satellite based communication method, if the calculated distance is less than the distance threshold.

12. The apparatus as claimed in claim 11, wherein the location of the UE is calculated using GPS, if the calculated distance is less than the distance threshold.

13. The apparatus as claimed in claim 11, wherein an alerting system is activated by a user of the UE.

14. The apparatus as claimed in claim 11, wherein the alternate positioning method is at least one of a cell-ID based positioning system, Wi-Fi positioning system, and Observed Time Difference of Arrival (OTDA) positioning system.

15. The apparatus as claimed in claim 14, wherein the cell-ID based positioning system is at least one of a Secure User Plane Location (SUPL) protocol based cell-ID positioning system, cell-ID in control plane based positioning system, and enhanced cell-ID.

16. The apparatus as claimed in claim 14, wherein the cell-ID based positioning system gives priority to umbrella cells over micro cells, macro cells and pico cells.

17. The apparatus as claimed in claim 16, wherein the algorithm selection unit stores at least one of cell IDs, location of the cell IDs, and priority of cells corresponding to the cell IDs in a database.

18. The apparatus as claimed in claim 11, wherein the satellite based communication method is at least one of Global Positioning System (GPS), and Assisted GPS (AGPS).

19. The apparatus as claimed in claim 11, wherein the algorithm selection unit calculates location of the UE using GPS at periodic intervals, if the calculated distance is greater than or equal to a predetermined second threshold.

20. The apparatus as claimed in claim 19, wherein the periodic intervals depend on at least one of speed of the UE, direction of travel of the UE with respect to the alerting area, and distance of the UE from the alerting area.
