Abstract

In an example embodiment, there is described herein an apparatus comprising an interface and logic operable receive data from a device via the interface. The logic is operable to estimate a location of the device based on data received via the interface based on a first (e.g. default) location classification. The logic is further operable to estimate a location of the device based on data received via the interface based on a second location classification responsive to a predefined trigger.

Claims

1. An apparatus, comprising:

an interface;

a location estimator operable to receive data from a device via the interface;

wherein the location estimator is operable to estimate a location of the device based on data received via the interface based on a first location classification; and

wherein the location estimator is operable to estimate the location of the device based on data received via the interface based on a second location classification while a predefined condition exists.

2. The apparatus set forth in claim 1, wherein the second location classification provides a more precise location estimate than the first location classification.

3. The apparatus set forth in claim 1, wherein the predefined condition is a time of day.

4. The apparatus set forth in claim 1, wherein the predefined condition is when the device is within a predefined area.

5. The apparatus set forth in claim 1, wherein the predefined condition is remaining battery life falling below a predetermined threshold.

6. The apparatus set forth in claim 1, wherein the predefined condition is insufficient resources to provide the estimated location based on the first location classification.

7. The apparatus set forth in claim 6, wherein the device employs a first protocol for providing data for providing the estimated location based on the first protocol;

and

wherein the location estimator is operable to send data to the device to change to a second protocol responsive to the predefined trigger.

8. The apparatus set forth in claim 1, wherein a first periodicity is employed to estimate the location of the device for the first location classification, and a second periodicity is employed to estimate the location of the device for the second location classification.

9. The apparatus set forth in claim 1, wherein data is sent to the device by the location estimator via the interface to instruct the device to employ a first protocol to obtain data to estimate the location of the device for the first location classification, and data is sent to the device data is sent to the device by the location estimator via the interface to instruct the device to employ a second protocol to obtain data to estimate the location of the device while the device is in the second location classification.

10. The apparatus set forth in claim 1, wherein a first algorithm is employed by the location estimator to estimate the location of the device for the first location classification, and a second algorithm is employed by the location estimator to estimate the location of the device for the second location classification.

11. The apparatus set forth in claim 1, wherein data associated with multiple interfaces is employed by the location estimator to estimate the location of the device while in the second location classification.

12. The apparatus set forth in claim 1, wherein the location classification for the device is changed to the second location classification responsive to receiving a request for the device'"'"'s location.

13. A method, comprising:

determining a current location classification for a device;

estimating a current location for the device with a first location estimating technique responsive to determining the device is in a first location classification category; and

estimating the current location for the device with a second location estimating technique responsive to determining the device is in a second location classification category;

wherein the device is determined to be in the second location classification responsive to a predefined event.

14. The method according to claim 13, wherein the device is determined to be in the second location classification category during a predefined time of day.

15. The method according to claim 13, wherein the device is determined to be in the second location classification category responsive to remaining battery life falling below a predetermined threshold.

16. The method according to claim 13, wherein the device is determined to be in the second location classification category while the device is within a predefined area.

17. The method according to claim 13, wherein data for determining the location of the device is acquired using a first wireless protocol while the device is in the first location classification category and data for determining the location of the device is acquired using a second wireless protocol while the device is in the second location classification category.

18. The method according to claim 13, wherein the estimate of the location of the device is based on a first periodicity while the device is in the first location classification category, and the estimate of the location of the device is based on a second periodicity while the device is in the second location classification category.

19. The method according to claim 13, wherein the device is determined to be in the second location classification category responsive to detecting location jitter.

20. Logic encoded in at least one tangible media for execution by a processor and when executed operable to:

employ a first location estimation technique for estimating a location of a device selected from a plurality of location estimation techniques based upon a first location estimation category associated with the device; and

employ a second location estimation technique selected from the plurality of location estimation techniques while a predefined condition exists.
