Problems solved by technology

[0004] At the same time, the current third-party WLAN positioning is mostly realized by activating the resident positioning program of the terminal by the third party. The positioning calculation is performed on the terminal side, and the terminal needs to install the resident program or client software. resources, increasing the application complexity of WLAN third-party positioning

Embodiment Construction

[0026] The existing technology realizes the third-party positioning of WLAN. Firstly, the independent positioning of the WLAN terminal based on the fingerprint algorithm is realized, and then the third party activates the independent positioning software installed on the terminal through SMS, etc., and transmits the positioning result to the third party through the terminal.

[0027] This approach has certain limitations:

[0028] First of all, in the fingerprint algorithm, since the exact location of the AP device is not known, it is necessary to collect information of multiple fingerprint points, which are mostly carried out by user self-learning, that is, users with GPS and WLAN module terminals report the latitude and longitude of the point And the fingerprint information of the collected AP, this method consumes the resources of the user terminal and Internet traffic, leaks the location privacy of the user who does not participate in the positioning, and easily causes user...

Abstract

The invention provides a WLAN (wireless local area network) positioning method and a positioning server for positioning a third part. The positioning server receives a positioning request launched by the third part, searching an MAC (media access control) address corresponding to a WLAN networking account of a terminal to be positioned, inquiring an IP (internet protocol) address corresponding to the WLAN networking account; inquiring the corresponding relation between the IP address and the MAC address of an AP (access point), acquiring an MAC address list of the AP; acquiring a list of WLAN terminals related to the AP currently in the MAC address list of the AP; searching the list of the WLAN terminals according the MAC address of the terminal to be positioned, and finding out the MAC address of the AP related to the terminal to be positioned, searching longitude and latitude of the MAC address of the AP according to the corresponding relation between the longitude and the latitude and the MAC address of the AP, and acquiring the position of the terminal to be positioned, wherein the MAC address list of the AP includes the MAC address of an AP into which the terminal to be positioned accesses. Positioning time length is reduced and operation complexity of positioning of the third part is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication applications, in particular to a WLAN positioning method and a positioning server for a mobile terminal to realize third-party positioning. Background technique [0002] As WLAN chips mature, equipment costs drop, and WLAN has gradually become a must-have configuration for mobile phones, the user's mobile phone WLAN habit of surfing the Internet has gradually formed. At the same time, mobile operators are deploying more and more APs in public places, and it becomes possible to locate users through WLAN. [0003] At present, WLAN positioning is mostly provided by non-telecom operators. Since non-telecom operators have no network information data, they need to collect a large amount of WLAN wireless information as the basic data for location calculation. This collection method requires long-term collection, which is time-consuming and labor-intensive. At the same time, some service pr...
