Problems solved by technology

[0005] But in real life, most of the places are square or polygonal. If a circular fence is created around the polygonal building, there will inevitably be a redundant range within the fence, especially when the building is relatively long and narrow. The range will greatly exceed the range of the building itself, resulting in less accurate notifications or warnings

Abstract

The embodiment of this invention discloses a position detecting method and device based on geo-fencing, relates to the field of position service, and is used for improving the accuracy of the position detection. the method includes the steps of when a position update of a terminal is detected, acquiring a current geographical coordinate of the terminal; detecting whether the acquired geographical coordinate is located in a rectangular coverage area represented by each leaf node in a pre-structured R-tree structure or not; if so, acquiring an actual coverage range of a polygonal geo-fence located in the rectangular coverage area; further detecting whether the geographical coordinate is located in the actual coverage range of the polygonal geo-fence or not, and outputting a detection result; and thus, the accuracy of the position detection is improved.

Description

Technical field [0001] The invention relates to the field of location services, in particular to a location detection method and device based on geofences. Background technique [0002] Location-based service (LocationBasedService, LBS), is through the telecommunication mobile operator's radio communication network (such as GSM (Global System for Mobile Communication) network, CDMA (Code Division Multiple Access, CodeDivision Multiple Access) network) or external positioning methods (such as GPS (Global Positioning System, GlobalPositioningSystem)) A value-added service that obtains location information (geographical coordinates, or geodetic coordinates) of mobile terminal users, and provides users with corresponding services under the support of GIS (Geographic Information System) platform. [0003] Geo-fencing (Geo-fencing) is an application of LBS, which uses a virtual fence to enclose a virtual geographic boundary. When the mobile phone enters, leaves a certain geographic area,...
