Location tracking based on overlapping geo-fences
First Claim
1. A computer-readable storage medium storing computer-executable instructions for controlling a device to track a location of the device, the computer-executable instructions comprising instructions that:
- identify a location of the device;
after the location of the device is identified, identify a plurality of first areas that are centered on the identified location, that have different sizes, and that each encompasses all smaller first areas, the first areas including a smaller first area and a larger first area; and
for each of the identified first areas, register the first area with a location provider to receive a notification when the location provider detects that the device has left the first area;
upon receiving a notification from the location provider that the device has left the smaller first area, register with the location provider a plurality of second areas centered on a new identified location of the device such that the location provider no longer provides a notification when the location provider detects that the device has left the larger first area; and
upon receiving a notification from the location provider that the device has left the larger first area, register with the location provider a plurality of second areas centered on a new identified location of the device such that the location provider no longer provides a notification when the location provider detects that the device has left the smaller first area;
wherein the plurality of areas are registered simultaneously with the location provider so the location provider can detect that the device has left any one of the plurality of areas even though the location provider did not detect that the device left a smaller area.

Abstract
A system for controlling a device to track the location of the device is provided. The system identifies an initial location of the device. The system then identifies a plurality of areas having different sizes. Each area encompasses the identified location. For each of the areas, the system registers the area with a location provider to receive a notification when the location provider detects that the device has left the area. Upon receiving a notification that the device has left an area, the system may repeat the process of identifying the location and the areas and registering the areas to continue tracking the location of the device.

11. A device for tracking the location of the device, the device comprising:
-
a computer-readable storage medium storing computer-executable instructions that initialize tracking of the device by; identifying a location of the device; identifying circular areas of different radiuses, each circular area with a center derived from the identified location, at least one of the radiuses being based on a speed of travel of the device, the circular areas including a first circular area with a first radius and a second circular area with a second radius, the first radius being smaller than the second radius; and registering the circular areas with a location provider of the device to receive notification that the location provider has detected that the device has crossed the boundary of a circular area wherein multiple circular areas are registered with the location provider so that the location provider is enabled to detect the device crossing any of the boundaries of the circular areas; upon receiving a notification that the location provider has detected that the device has crossed a boundary of the first circular area, re-initialize tracking of the device so that the tracking is based on circular areas derived from a new location of the device; and upon receiving a notification that the location provider as detected that the device has crossed a boundary of the second circular area, re-initialize tracking of the device so that the tracking is based on circular areas derived from a new location of the device; and a processor for executing the computer-executable instructions of the computer-readable storage medium. - View Dependent Claims (12, 13, 14)

15. A method performed by a device for tracking the location of the device, the method comprising:
-
initializing tracking of the device by; identifying a location of the device; identifying overlapping areas, each area overlapping the identified location of the device, the areas including a first area and a second area; and registering the areas with a location provider of the device to receive notification that the location provider has detected that the device has crossed the boundary of an area wherein multiple areas are registered with the location provider so that the location provider is enabled to detect the device crossing any of the boundaries of the areas; upon receiving a notification that the location provider has detected that the device has crossed the boundary of the first area, re-initializing tracking of the device so that the tracking is based on areas derived from a new location of the device; and upon receiving a notification that the location provider as detected that the device has crossed a boundary of the second area without having received a notification that the location provider detected that the device crossed the boundary of the first area even though the device crossed the boundary for the first area, re-initializing tracking of the device so that the tracking is based on areas derived from a new location of the device.

16. A method performed by a device for tracking the location of the device, the method comprising:
-
registering a first area and a second area with a location provider of the device to receive notification that the location provider has detected that the device has crossed a first boundary of the first area and a second boundary of the second area, wherein the device is at a current location that is within both the first area and the second area; upon receiving a notification that the location provider has detected that the device has crossed the first boundary, registering with the location provider of the device a new area to receive notification that the location provider has detected that the device has crossed a new boundary of the new area, wherein the device is at a new location that is within the new area; and upon receiving a notification that the location provider has detected that the device has crossed the second boundary without having received a notification that the location provider detected that the device crossed the first boundary even though the device crossed the first boundary, registering with the location provider of the device a new area to receive notification that the location provider has detected that the device has crossed a new boundary of the new area, wherein the device is at a new location that is within the new area. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25)
