Beacon-Based Geofencing
First Claim
1. A computer-implemented method performed by a mobile device, comprising:
- causing an application subsystem of the mobile device to receive a first location estimate of the mobile device in a geographic area, the first location estimate having a first accuracy;
detecting a broadcast signal transmitted by a beacon located in the geographic area;
processing the broadcast signal to determine a second location estimate of the mobile device in the geographic area that is more accurate than the first location estimate, the processing performed by a baseband subsystem of the mobile device, where the baseband subsystem consumes less power than the application subsystem; and
processing the broadcast signal to determine services available to the mobile device in the geographic area.

Abstract
A mobile device can monitor a current location using a multi-tier approach. A baseband subsystem can monitor a coarse location of the mobile device using various course location parameters, such as a mobile country code (MCC), a location area code (LAC), or a cell identifier (cell ID), as the mobile device moves closer to the geographic region. Upon determining that the mobile device is in a cell that intersects the geographic region, the baseband subsystem can transfer the monitoring to the application subsystem. The task can be performed when the application subsystem determines that the mobile device is currently located in the geographic region. A beacon network can provide more accurate estimates of mobile device location and advertise location based services available to the mobile device.
