Embodiment Construction

[0054] The embodiment of the present invention solves the technical problem that cross-floor message push cannot be realized in the prior art by providing a cross-floor message push method and device, thereby achieving the goal of improving the punctuality and accuracy of message push in an indoor space environment technical effect.

[0055] The technical solution in the embodiment of the present invention is to solve the above-mentioned problems, and the general idea is as follows:

[0056] First establish a geofence based on the grid graph model, and then judge whether the received real-time location, timestamp, and stay time of the user meet the constraints of the geofence; if so, push a message to the requester. The embodiment of the present invention uses a grid graph model composed of nodes and edges to represent the range of the indoor geographical fence space, thereby realizing the representation of the fenced area on multiple floors in the indoor three-dimensional spa...

Abstract

The invention discloses a trans-storey message pushing method and a trans-storey message pushing device. The method at least includes: establishing geographical fences on the basis of a grid model; receiving a user real-time position, a timestamp and a staying duration; judging whether the user real-time position, the timestamp and the staying duration meet constraint conditions of the geographical fences or not; if yes, pushing messages to a requester. The grid model formed by nodes and sides is adopted for representing an indoor space range of the geographical fences, and accordingly representation of multi-storey fence areas in an indoor three-dimensional space is realized, indoor trans-storey pushing of service messages is supported, and timeliness and accuracy in message pushing in an indoor space environment are improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a cross-floor message pushing method and device. Background technique [0002] The emergence of geo-fencing technology has greatly promoted the development of active location services. When a user enters or exits a specific geographical area, the message associated with the area will be triggered and sent to the user. For example, in the vehicle monitoring application, when the vehicle leaves a specific area, the system will remind the background management personnel that the vehicle exceeds a certain range. Geofence technology mainly involves three parts: geofence design, real-time location sampling (ie positioning) and space matching. [0003] With the development of indoor positioning technology, geo-fencing has gradually moved from outdoors to indoors. Current indoor geo-fences are mainly based on wireless indoor positioning means to automatically identify geo-fences...
