Method for implementing geo-fencing and mobile device

摘要

A method includes determining a first coordinate representing the geo-fence in a first coordinate system when it is detected that a geo-fence is set, where the first coordinate system is a coordinate system used by the geo-fence, converting the first coordinate into a second coordinate representing the geo-fence in a second coordinate system, where the second coordinate system is a coordinate system set to implement geo-fencing by a positioning technology, and the first coordinate system is different from the second coordinate system, comparing a coordinate of a positioning result determined using the positioning technology with the second coordinate representing the geo-fence, and triggering a preset event when a relationship between the coordinate of the positioning result and the second coordinate representing the geo-fence satisfies a trigger condition.
