Abstract: A method including receiving, at a mobile device, a request to provision a first geofence. The first geofence has a first predicted duration that expires before a second predicted geofence is provisioned by the mobile device. Provisioning the first geofence and the second predicted geofence together consume a first amount of power. The method also includes determining a predictive geofence radius based on a predicted speed of the mobile device. The method also includes provisioning a first predictive geofence having the predictive geofence radius and further having a second predicted duration that is different than the first predicted duration and that expires before a second predictive geofence is provisioned by the mobile device. Provisioning the first predictive geofence and the second predictive geofence together consume a second amount of power, the second amount of power less than the first amount of power.

Abstract: A method for determining location based on nearby devices includes receiving a broadcast message from a proximate device over a wireless personal area network, triggering an event that requires recording location data and time data, and establishing a connection over the wireless personal area network to the proximate device. The method further includes requesting proximate location data from the proximate device over the connection with a user device location request and receiving the proximate location data from the proximate device in a proximate device location response.

Abstract: A method including receiving, at a mobile device, a request to provision a first geofence. Geolocation hardware on the mobile device determines a current position of the mobile device. Roads are identified within a predetermined number of turns of the current position. Corresponding speed limits applicable to the roads within the predetermined number of turns are retrieved. A predicted average speed of the mobile device is determined by averaging the corresponding speed limits A predictive geofence radius is determined based on the predicted average speed. A first predictive geofence having the predictive geofence radius is provisioned. The first predictive geofence has a third predicted duration before a second predictive geofence is provisioned by the mobile device. Provisioning the first predictive geofence and the second predictive geofence together consume less power than provisioning geofences without prediction.
