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. 1. A method , comprising: associating the network with a geographic region, wherein the signal from at least one beacon in the network is detectable by a mobile device located in the geographic region;', 'designating an encompassment of the geographic region as the geofence; and', 'associating a task with the geofence as a location based service;, 'defining a geofence using a network of one or more beacons, wherein each beacon is a communication device configured to provide a signal detectable by a baseband subsystem of a mobile device located within a communication range of the respective beacon, defining the geofence includingadvertising the geofence, including broadcasting, by each beacon in the network, an identification signal indicating that the beacon is a component of the network;determining that the mobile device has entered the geofence when the mobile device is in communication with at least one beacon in the network; andupon determining that the mobile device has entered the advertised geofence, triggering the mobile device to perform the task,wherein the method is performed by one or more processors.2. The method of claim 1 , wherein the beacon is a short range ...
