METHOD AND APPARATUS FOR IMPROVED GEOFENCING BACKGROUND
The disclosure generally relates to a method and apparatus for determining a coarse geofence of a mobile device. An exemplary method includes: identifying, at the device, a first perimeter for the location, the first perimeter enclosed by a geofence region; identifying a second perimeter for the location, the second perimeter enclosing the geofence regions; and determining if the device is one of an inside the first perimeter or an outside the second perimeter. The exemplary steps can be implemented as part of a software, a firmware or a dedicated chipset.
1 . An apparatus to detect a coarse geofence location of a mobile device, comprising:
a first module configured to identify a first boundary enclosed by the geofence perimeter and a second boundary enclosing the geofence perimeter;
a second module configured to determine if the mobile device is inside the first boundary or outside the second boundary.
2 . The apparatus of claim 1 , further comprising a third module to transmit the coarse geofence location of the mobile device relative to the first boundary and/or the second boundary.
3 . The apparatus of claim 1 , wherein the first boundary and the second boundary overlap.
4 . The apparatus of claim 1 , wherein each of the first boundary and the second boundary is defined by a respective center coordinates and an area.
5 . The apparatus of claim 1 , wherein the first module is further configured to define an inconclusive condition if the mobile device is not inside the first boundary and not outside the second boundary.
6 . The apparatus of claim 5 , wherein one of the first or the second module is further configured to determine if the mobile device is within the geofence perimeter when the inconclusive conditions exist.
7 . The apparatus of claim 1 , further comprising a processor configured to determine the first boundary and the second boundary as geometric areas relevant to the geofence perimeter.
8 . The apparatus of claim 1 , wherein one of the first or the second module is further configured to notify a server when the mobile device enters or exists one of the first or the second boundaries.
9 . A system comprising:
a memory;
a processor;
a radio;
one or more antennas;
a first module to identify a first boundary encompassed by the geofence region and a second boundary encompassing the geofence perimeter;
a second module configured to determine if the mobile device is inside the first boundary or outside the second boundary.
10 . The system of claim 9 , further comprising a third module to transmit a coarse geofence location of the mobile device relative to the first boundary and/or the second boundary.
11 . The system of claim 9 , wherein the first boundary and the second boundary overlap.
12 . The system of claim 9 , wherein each of the first boundary and the second boundary is defined by a respective center coordinates and an area.
13 . The system of claim 9 , wherein the first module is further configured to define an inconclusive condition if the mobile device is not inside the first boundary and not outside the second boundary.
14 . The system of claim 9 , wherein one of the first or the second module is further configured to notify a server when the mobile device enters or exists one of the first boundary or the second boundary.
15 . A method to determine a coarse geofence location of a mobile device, the method comprising:
identifying, at the device, a first boundary for the location, the first boundary enclosed by a geofence perimeter;
identifying a second boundary for the location, the second boundary enclosing the geofence perimeter; and
determining if the device is inside the first boundary or outside the second boundary.
16 . The method of claim 15 , wherein the first boundary and the second boundary overlap.
17 . The method of claim 15 , wherein each of the first boundary and the second boundary is defined by respective center coordinates and an area.
18 . The method of claim 15 , further comprising defining an inconclusive condition if the device is not inside the first boundary and not outside the second boundary.
19 . The method of claim 18 , further comprising determining if the device is within the geofence perimeter when the inconclusive conditions exist.
20 . The method of claim 15 , further comprising determining the first boundary and the second boundary as geometric areas relevant to the geofence perimeter.
21 . The method of claim 15 , further comprising notifying a server when the mobile device is either entering or exiting one of the first or the second boundaries.
22 . A tangible computer-readable storage device containing a set of instructions to cause a computer to perform a process comprising identifying, at the device, a first boundary for the location, the first boundary enclosed by a geofence perimeter; identifying a second boundary for the location, the second boundary enclosing the geofence perimeter; and determining if the device inside the first boundary or an outside the second boundary.
23 . The tangible computer-readable storage device of claim 22 , wherein the instructions further cause the computer to define an inconclusive condition if the device is not inside the first boundary and not outside the second boundary.
24 . The tangible computer-readable storage device of claim 22 , wherein the instructions further cause the computer to determine if the device is within a geofence perimeter when the inconclusive conditions exist.
25 . The tangible computer-readable storage device of claim 22 , wherein the instructions further cause the computer to determine the first boundary and the second boundary as geometric areas relevant to the geofence perimeter.
