摘要： A mobile device running a software application is configured to provide initial location data to a server when it is first turned on, or reaches a predetermined movement status. The server determines, based on the initial location data, geo data including a set of geo-fences near the mobile device and a region including areas defined by the set of geo-fences, and provides the geo data to the mobile device. The mobile device is further configured to collect its locations when the mobile device is within any of the set of geo-fences and to provide the collected locations to the server. The mobile device is further configured to track its movement status after it has been outside the region and, in response to having reached a predetermined movement status, obtain updated geo data including a new region and a new set of geo-fences from the server. The software application enables efficient tracking of mobile device locations and reduces power consumption.
