Abstract
Methods, systems and devices are provided for operating a GPS engine in an active geofence monitoring state for no more than a first QoS period to obtain a first GPS fix. The GPS engine may also be set to operate in the active geofence monitoring state for no more than a second lower QoS period to obtain a second GPS fix in response to determining the first GPS fix was not obtained. The method may determine whether a geofence breach is detected in response to determining the GPS engine obtained the first GPS fix. The GPS engine may be set to operate in the active geofence monitoring state for no more than the second QoS period to obtain the second GPS fix in response to determining the geofence breach is not detected. The GPS engine may thus operate in the active geofence monitoring state to obtain the second GPS fix.
