摘要

A method is provided for determining when a mobile communications device has crossed a geo-fence. The method comprises (a) providing a mobile communications device (209) equipped with an operating system and having a location detection application resident thereon, wherein the mobile communications device is in communication with a server (211) over a network (203), and wherein the server maintains a geo-fence database (213); (b) receiving, from the operating system, a notification that (i) the location of the mobile communications device has changed by an amount that exceeds a predetermined threshold, or (ii) that a period of time has passed; (c) querying the operating system for a data set comprising the general location of the mobile communications device and the corresponding location accuracy; (d) transmitting the data set to the server; and (e) receiving from the server, in response, a set of geo-fences (205) proximal to the general location.
