Abstract

The invention discloses a behavior trace detection analysis and service providing system and method based on APs. The system comprises a signal collection module, a data signal receiving interface, a positioning module, a positioning data storage module, a behavior trace analysis module and a service providing module, wherein the signal collection module is composed of multiple APs with the signal collection ability. The method includes the steps that (1) the APs collect wireless signal intensity between different terminals and MAC addresses of the terminals; (2) the mobile terminals are positioned; (3) position traces of the mobile terminals are analyzed; (4) corresponding services are provided according to service requests put forward by the mobile terminals and other devices. By means of the system and method, the outdoor and indoor mobile terminals can be positioned precisely in time, modification is carried out according to different mobile terminal attributes, and positioning precision is increased. Platform limitations do not exist, positioning and position data analysis can be carried out on mobile phones, notebook computers, tablet computers and other mobile terminals, and accordingly corresponding services are provided for terminal users and other users.

Description

technical field [0001] The present invention relates to a positioning, location analysis system and implementation method, in particular to an AP positioning, location and behavior analysis system and implementation method based on Wi-Fi technology. Background technique [0002] With the rapid increase of data services and multimedia services, people's demand for positioning and navigation is increasing, especially in complex indoor environments, such as airport halls, exhibition halls, warehouses, supermarkets, libraries, underground parking lots, mines, etc. , it is often necessary to determine the location information of the mobile terminal or its holder, facilities and objects indoors. In recent years, with the rapid development and increasing popularity of mobile device technology, how to make full use of the mobility of devices to provide users with richer and more complete services has attracted the attention of many researchers, and location-based services (Location ...
