Problems solved by technology

[0006] Among them, the important purpose of the network planning software is to provide specific data and diagrams to guide the next more accurate network layout, so that each location has a fixed fingerprint structure; but because the actual environment varies greatly, each network layout requires A lot of work is done to simulate the environment, which is very cumbersome and the accuracy is not high; in addition, the collection of fingerprint vectors is very cumbersome and time-consuming, so the existing technical solution of using radio frequency fingerprint recognition technology to realize positioning is not easy to be promoted

Embodiment approach

[0052] This embodiment provides an implementation manner in which the positioning server obtains the reference fingerprint feature vector, which specifically includes:

[0053] Step 201, the positioning server sends a second positioning indication message to one or more APs through the AC, so that one or more APs can collect the RSSI of the test equipment located at a specified location, and the second positioning indication message includes the test equipment and the location coordinates of the specified location;

[0054] Wherein, this embodiment is still implemented based on the radio frequency fingerprint positioning system in the above embodiments. The second positioning indication message is a positioning indication message sent by the positioning server to the AP in order to obtain the reference fingerprint feature vectors corresponding to each positioning point in the positioning system. The identification of the test equipment is included in the positioning indicatio...

Abstract

The invention provides a radio frequency fingerprint positioning method and system as well as an access controller (AC) and a positioning server. The method comprises the following steps: the positioning server sends a first positioning indication message which contains an identifier of the appointed equipment to an access point (AP) through the AC, so the AP can collect the received signal strength indication (RSSI) of the appointed equipment; the AC receives the RSSI of the appointed equipment fed back from the AP, filters the RSSI of the appointed equipment according to a preset dimensional threshold value and an RSSI threshold value to generate a fingerprint feature vector at least containing the preset dimensional threshold value number of the RSSI, and sends the fingerprint feature vector to the positioning server; and the positioning server positions the appointed equipment according to the fingerprint feature vector and a preserved standard fingerprint feature vector containing at least the preset dimensional threshold value number of the RSSI and position coordinates. By utilizing the technical scheme of the invention, the complexity of positioning by using a radio frequency fingerprint technique can be decreased, and the positioning precision can be increased.

Description

technical field [0001] The invention relates to network communication technology, in particular to a radio frequency fingerprint positioning method, system, wireless controller and positioning server. Background technique [0002] Wireless Local Area Networks (WLAN for short) refers to a network that uses wireless communication technology to interconnect computer equipment so that clients can access broadband networks anytime and anywhere to realize information sharing. Wherein, a wireless client (for example: a notebook computer supporting a WLAN access function, a personal digital assistant or a wireless network card) accesses the wireless local area network through a wireless access point (Access Point; AP for short). The AP is a bridge connecting the wired network and the wireless local area network. Its main function is to connect various wireless clients together, and then connect the wireless network to the Ethernet. [0003] A wireless controller (Access Controller;...
