Method and system for resource optimized, coarse and fine grained location tracking for planned journey

摘要

Methods and systems for resource optimized, coarse and fine grained location tracking for planned journey are disclosed. A method for tracking a mobile device with respect to a point of interest (POI) using a mobile location tracker includes a conserve mode in which the mobile location tracker is turned off. The conserve mode comprises determining, by an analyzer module, whether to assess an estimated time to arrive (ETA) at the POI. If determined to assess the ETA, the conserve mode comprises performing an ETA assess operation comprising receiving the ETA; and if the ETA is not greater than a threshold time, switching from the conserve mode to an active mode, wherein in the active mode the mobile location tracker is turned on. It is determined to assess the ETA if a timer measurement is not less than the reassess time or if a trigger to reassess is received.
