Battery-saving in geo-fence context method and system

摘要

While traveling to a destination, potentially traversing geo-fences along the way, a routine on a mobile device estimates arrival at the next geo-fence and performs a location check at the estimated arrival time. Between iterations of this process, the routine may correct the “time of next check” based on correction factors. When the mobile device arrives at the destination, it switches to terrestrial location determining services. In addition, the mobile device monitors its sensors to determine whether motion is gross motion which may warrant performing a location probe or whether motion is not gross motion, in which case location probes may be disabled.
