Abstract

In one embodiment, a method includes 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 current location of the mobile device; determining, by the processors of the geographic-positioning component, whether the current location is outside a geographic region defined at least in part by the first location; and if the current location 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 current location of the mobile device;

detecting, by the processors of the geographic-positioning component, a current status of the mobile device, the current status comprising;

a detected velocity of the mobile device;

time of day information;

a battery level of the mobile device; and

an error of the determined location measurement;

calculating, by the processors of the geographic-positioning component, a radius defining a geographic region around the first location, wherein the size of the radius is adjusted from a pre-determined value based on one or more components of the current status;

determining, by the processors of the geographic-positioning component, whether the current location is outside the geographic region; and

if the current location 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, wherein the message identifies the current location.

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

a global positioning system (GPS) signal;

a Wi-Fi signal;

or

a cellular radio signal.

4. One or more computer-readable non-transitory storage media within a mobile device, the media embodying logic that is operable when executed to:

record a first location of a mobile device;

determine on a periodic basis a current location of the mobile device;

detect, by the processors of the geographic-positioning component, a current status of the mobile device, the current status comprising;

a detected velocity of the mobile device;

time of day information;

a battery level of the mobile device; and

an error of the determined location measurement;

calculate a radius defining a geographic region around the first location, wherein the size of the radius is adjusted from a pre-determined value based on one or more components of the current status;

determine, by the processors of the geographic-positioning component, whether the current location is outside the geographic region; and

if the current location is outside the geographic region, then send a message to one or more processors of the mobile device, the message causing one or more of the processors to transition from a sleep state to an active state.

5. The method of claim 4, wherein the message identifies the current location.

6. The media of claim 4, wherein the first or current location is based at least in part on:

a global positioning system (GPS) signal;

a Wi-Fi signal;

or

a cellular radio signal.

7. A system 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 a mobile device;

determine on a periodic basis a current location of the mobile device;

detect, by the processors of the geographic-positioning component, a current status of the mobile device, the current status comprising;

a detected velocity of the mobile device;

time of day information;

a battery level of the mobile device; and

an error of the determined location measurement;

calculate a radius defining a geographic region around the first location, wherein the size of the radius is adjusted from a pre-determined value based on one or more components of the current status;

determine, by the processors of the geographic-positioning component, whether the current location is outside the geographic region; and

if the current location is outside the geographic region, then send a message to one or more processors of the mobile device, the message causing one or more of the processors to transition from a sleep state to an active state.

8. The system of claim 7, wherein the message identifies the current location.

9. The system of claim 7, wherein the first or current location is based at least in part on:

a global positioning system (GPS) signal;

a Wi-Fi signal;

or

a cellular radio signal.
