Dynamic duty-cycling of processor of mobile device based on operating condition of mobile device
View Patent ↗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.
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.
