Abstract

A mobile device can include an application configured to set an update interval for location information characterizing a location of the mobile device based on a current location of the mobile device and a location of a wireless device has an associated geofence. The update interval can define an interval of time between queries for the location information.

Claims

1. A mobile device comprising:

a memory configured to store machine readable instructions; and

a processing unit configured to access the memory and execute the machine readable instructions, the machine readable instructions comprising;

an application configured to set an update interval for location information characterizing a location of the mobile device based on a current location of the mobile device and a location of a wireless device that has an associated geofence, wherein the update interval defines an interval of time between queries for the location information.

2. The mobile device of claim 1, further comprising:

a location sensor configured to;

receive radio frequency (RF) signals from a plurality of satellites; and

determine the location information based on the received satellite signals in response to a query for the location information.

3. The mobile device of claim 1, wherein the update interval is further based on a velocity vector of the mobile device.

4. The mobile device of claim 3, wherein the application comprises an interval calculator that employs an adaptive algorithm to set the update interval.

5. The mobile device of claim 1, wherein the update interval further defines an interval of time between requests for scans of wireless devices.

6. The mobile device of claim 5, further comprising a wireless interface to scan for wireless devices in response to a request.

7. The mobile device of claim 6, wherein the application is further configured to determine whether an identifier (ID) of a detected wireless device is included in a geofence table.

8. The mobile device claim 7, wherein ID of the wireless device is one of a service set identifier (SSID) that is received via the Wi-Fi protocol or the Bluetooth protocol.

9. The mobile device of claim 7, wherein the application is further configured to initiate a geofence entry event for a boundary of a geofence in response to determining that the wireless ID of the detected wireless device is included in the geofence table.

10. The mobile device of claim 9, wherein the geofence entry event comprises providing the wireless ID of the detected wireless device to an enterprise server.

11. The mobile device of claim 9, wherein the application is configured to:

receive a message from the enterprise server in response to the providing; and

output content of the message.

12. The mobile device of claim 9, wherein the enterprise server is configured to provide a third party device with a message indicating that the mobile device is within the boundary defined by the geofence.

13. The mobile device of claim 9, wherein the geofence entry event omits transmission of the location information to the enterprise server.

14. The mobile device of claim 9, wherein the application is further configured to initiate a geofence exit event in response to losing communication with the detected wireless device.

15. The mobile device of claim 14, wherein the geofence exit event comprises:

providing an indication to the enterprise server that the mobile device has exited the geofence; and

setting the update interval.

16. The mobile device of claim 15, wherein the enterprise server is further configured to provide a third party device with a message indicating that the mobile device has exited the boundary defined by the geofence.

17. A non-transitory machine readable medium having machine executable instructions, the machine executable instructions comprising an application configured to determine an update interval that defines an interval of time between queries to a location sensor for updated location information and an interval of time between requests for scans for wireless devices at a wireless interface, wherein the determination is based on a velocity vector of a mobile device and a distance between the mobile device and a location of a wireless device that has an associated geofence.

18. The non-transitory machine readable medium of claim 17, wherein the application comprises an adaptive algorithm configured to determine the update interval.

19. A method comprising:

setting an update interval that defines an interval of time between queries to a location sensor for updated location information and an interval of time between requests for scans for wireless devices at a mobile device, wherein the update interval is based on a velocity vector of the mobile device and a distance between the mobile device and a location of a wireless device that has an associated with a geofence;

initiating a geofence entry event for a geofence in response to identifying a detected wireless device; and

providing an identifier of the wireless device to an enterprise server in response to the initiating.

20. The method of claim 19, further comprising receiving a message from the enterprise server in response to the providing.
