A positioning method for a terminal device, a positioning server, an access point, and a system

Abstract

A positioning method for a terminal device, a positioning server, an access point, and a system, wherein a method may include: the positioning server acquires an identifier of a terminal that needs to be positioned (201); Obtain a set of access points used to locate the terminal, where the set of access points includes: an associated access point accessed by the terminal, a non-associated access point not accessed by the terminal, and the non-associated access point The associated access points include at least the access points that cover the terminal within the coverage area (202); the positioning server obtains the positioning measurement information obtained after the interaction between the set of access points and the terminal (203); The positioning server acquires position information of the terminal according to the positioning measurement information (204).

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a terminal device positioning method, a positioning server, an access point, and a system. Background technique [0002] The method of locating a terminal through a wireless local area network (Wireless Local Area Networks, WLAN) is currently more and more widely used, especially in an indoor scene. The location information of the terminal obtained through WLAN positioning can be used for big data analysis, precise release of advertising information, and indoor navigation. [0003] At present, in the WLAN positioning technology, the positioning system obtains the signal strength of the same terminal to multiple access points (AccessPoint, AP), or the signal strength of multiple APs to the same terminal, and uses the signal strength information to calculate through the positioning algorithm out of the terminal location. Wherein, the acquisition of the sig...

Problems solved by technology

[0005] In the process of implementing the present invention, the inventors of the present invention found that the above-mentioned network-side positioning method has at least the following defects: the way of deploying probes will significantly increase the hardware cost

However, in the way of different channel scanning, there are problems no matter whether the AP stays on the different channel for too long or too short. The probability is greatly reduced, resulting in a significant drop in positioning accuracy

If the AP stays on different channels for too long, it will cause a lot of service packet loss and air interface service time loss, resulting in a significant decline in service performance

Therefore, to achieve network-side positioning, the residence time of the AP in different channels needs to be precisely controlled, but it is difficult to accurately control in reality
