Abstract

In providing a wireless location communication service including a location based service to a user of a mobile device, the mobile device sends information concerning a location of the device relative to a given position in a wireless communication system. The given position may be that of a base station in the system. First information concerning a location of the base station (e.g, GPS information) is communicated to the mobile device, e.g., via broadcast. The mobile device determines second information concerning its location, e.g., based on signals from GPS satellites received thereby. The mobile device then generates relative location information based at least on the first and second information.

Claims

1. A wireless communication system for serving a plurality of mobile devices, comprising:

a receiver for receiving via a wireless medium from a mobile device first information, the first information indicating a direction and a distance of the mobile device relative to a given position in the wireless communication system, the given position being indicated to the mobile device in accordance with a selected coordinate system; and

a controller configured to determine second information, concerning a location of the mobile device based at least on the received first information, and data concerning the given position,

wherein the second information defines the location of the mobile device in accordance with the selected coordinate system; and

wherein the first information is formatted in a different format than the second information.

2. The system of claim 1 wherein the first information is formatted in a plurality of data elements representing the relative location of the mobile device.

3. The system of claim 2 wherein at least one of the data elements indicates the direction and the distance.

4. The system of claim 1 wherein the second information is formatted in a GPS data format.

5. The system of claim 1 wherein the data concerning the given position is formatted in a GPS data format.

6. The system of claim 1 wherein the given position is a position of a base station.

7. The system of claim 1 wherein the second information is determined also based on data concerning a distance resolution.

21. The system of claim 1 further comprising a transmitter for broadcasting the given position to at least the mobile device.

8. Apparatus capable of wireless communications through a wireless communication system, comprising:

a receiving portion for receiving via a wireless medium first information, concerning a given position in the wireless communication system in accordance with a selected coordinate system;

a location device for providing second information, concerning a location of the apparatus in accordance with the selected coordinate system;

a processing element configured to generate data concerning the location of the apparatus relative to the given position based at least on the first and second information, the data indicating a direction and a distance and being formatted in a different format than the second information; and

a transmitting portion for transmitting the generated data.

9. The apparatus of claim 8 wherein the first information is formatted in a GPS data format.

10. The apparatus of claim 8 wherein the location device comprises a GPS receiver for receiving satellite signals.

11. The apparatus of claim 8 wherein the given position is a position of a base station.

12. The apparatus of claim 8 wherein the data is generated also based on data concerning a distance resolution.

13. The apparatus of claim 8 wherein the data is formatted in a plurality of data elements, at least one of which indicates the direction and the distance.

14. A method for use in a wireless communication system for serving a plurality of mobile devices, comprising:

receiving via a wireless medium from a mobile device first information, the first information indicating a direction and a distance of the mobile device relative to a given position in the wireless communication system, the given position being indicated to the mobile device in accordance with a selected coordinate system; and

determining second information, concerning a location of the mobile device based on the received first information, and data concerning the given position,

wherein the second information defines the location of the mobile device in accordance with the selected coordinate system; and

wherein the first information is formatted in a different format than the second information.

15. The method of claim 14 wherein the first information is formatted in a plurality of data elements representing the relative location of the mobile device.

16. The method of claim 15 wherein at least one of the data elements indicates the direction and the distance.

17. The method of claim 14 wherein the second information is formatted in a GPS data format.

18. The method of claim 14 wherein the data concerning the given position is formatted in a GPS data format.

19. The method of claim 14 wherein the given position is a position of a base station.

20. The method of claim 14 wherein the second information is determined also based on data concerning a distance resolution.
