Abstract

In one embodiment, a method includes recording a first location of a mobile device; determining, by a geographic-positioning component of the mobile device, on a periodic basis, a trajectory of the mobile device, wherein the trajectory is calculated based on present and past user locations; determining, by the geographic-positioning component, whether the trajectory is outside a geographic region defined at least in part by the first location; and if the trajectory is outside the geographic region, then transmitting, by the processors of the geographic-positioning component, a message to one or more other processors of the mobile device, the message causing one or more of the other processors to transition from a sleep state to an active state.

Claims

1. A method comprising:

recording a first location of a mobile device;

determining, by one or more processors of a geographic-positioning component of the mobile device, on a periodic basis, a trajectory of the mobile device, wherein the trajectory is calculated based on present and past user locations;

determining, by the processors of the geographic-positioning component, whether the trajectory is outside a geographic region defined at least in part by the first location; and

if the trajectory is outside the geographic region, then sending, by the processors of the geographic-positioning component, a message to one or more other processors of the mobile device, the message causing one or more of the other processors to transition from a sleep state to an active state.

2. The method of claim 1, further comprising determining a radius associated with the mobile device, wherein the radius also defines at least in part the geographic region.

3. The method of claim 2, wherein the radius is determined based at least in part on a velocity of the mobile device.

4. The method of claim 2, wherein the radius is determined based at least in part on a time of day.

5. The method of claim 2, wherein the radius is determined based at least in part on a power budget of the mobile device.

6. The method of claim 2, wherein the radius is determined based at least in part on an error associated with the first or projected location.

7. The method of claim 1, wherein the message identifies the trajectory.

8. The method of claim 1, wherein the first location is based at least in part on:

a global positioning system (GPS) signal;

a Wi-Fi signal;

or

a cellular radio signal.

9. The method of claim 1, wherein the first location or the trajectory is based at least in part on user-submitted location data.

10. The method of claim 9, wherein the user-submitted location data comprises social-networking information submitted by using social-networking functionality.

11. One or more computer-readable non-transitory storage media embodying software that is operable when executed by one or more processors to:

record a first location of a mobile device;

determine, by one or more processors of a geographic-positioning component of the mobile device, on a periodic basis, a trajectory of the mobile device, wherein the trajectory is calculated based on present and past user locations;

determine, by the processors of the geographic-positioning component, whether the trajectory is outside a geographic region defined at least in part by the first location; and

if the trajectory is outside the geographic region, then send, by the processors of the geographic-positioning component, a message to one or more other processors of the mobile device, the message causing one or more of the other processors to transition from a sleep state to an active state.

12. The media of claim 11, the software being operable when executed by the processors to determine a radius associated with the mobile device, wherein the radius also defines at least in part the geographic region.

13. The media of claim 11, wherein the message identifies the trajectory.

14. The media of claim 11, wherein the first location or the trajectory is based at least in part on user-submitted location data.

15. The media of claim 14, wherein the user-submitted location data comprises social-networking information submitted by using social-networking functionality.

16. A mobile device comprising:

one or more processors; and

a memory coupled to the processors comprising instructions executable by the processors, the processors being operable when executing the instructions to;

record a first location of the mobile device;

determine, by one or more processors of a geographic-positioning component of the mobile device, on a periodic basis, a trajectory of the mobile device, wherein the trajectory is calculated based on present and past user locations;

determine, by the processors of the geographic-positioning component, whether the trajectory is outside a geographic region defined at least in part by the first location; and

if the trajectory is outside the geographic region, then send, by the processors of the geographic-positioning component, a message to one or more other processors of the mobile device, the message causing one or more of the other processors to transition from a sleep state to an active state.

17. The mobile device of claim 16, the processors being further operable when executing the instructions to determine a radius associated with the mobile device, wherein the radius also defines at least in part the geographic region.

18. The mobile device of claim 16, wherein the message identifies the trajectory.

19. The mobile device of claim 16, wherein the first location or the trajectory is based at least in part on user-submitted location data.

20. The mobile device of claim 19, wherein the user-submitted location data comprises social-networking information submitted by using social-networking functionality.
