Problems solved by technology

[0003] However, in many scenarios, it is possible that the original information changes due to changes in the location of the AP or the change in the signal strength of the AP, and the positioning server is still based on the original information of the AP (such as location information, signal strength information, etc.) for positioning, which will lead to inaccurate terminal position measurement

Embodiment Construction

[0047] In the positioning optimization method, device, and positioning server of the embodiments of the present invention, after supplementary positioning, it is judged whether there is an abnormal AP according to whether the two positioning results are consistent, so that after the abnormal AP is found, corresponding processing can be performed to reduce the abnormal cost. The impact of AP on positioning accuracy.

[0048] Before further describing the embodiments of the present invention in detail, the concepts involved in the embodiments of the present invention will be described first.

[0049] In the embodiment of the present invention, the abnormal AP refers to an AP whose positioning parameters used for positioning are different from the original parameters recorded in the database. For example, an AP whose location changes, or an AP whose signal strength changes.

[0050] The positioning optimization method of the embodiment of the present invention is used for a posi...

Abstract

The invention discloses a positioning optimization method, device and positioning server, wherein the positioning optimization method is used in a positioning server, including: obtaining a positioning parameter set sent by a first terminal to be positioned; A plurality of positioning parameters with one-to-one correspondence between entry points; use the set of positioning parameters to perform positioning to obtain a first positioning result; select some positioning parameters from the set of positioning parameters to obtain a first subset of positioning parameters; use the set of positioning parameters A subset of positioning parameters performs positioning to obtain a second positioning result; when the second positioning result is different from the first positioning result, it is determined that there is an abnormal access point among the plurality of access points. The present invention locates by selecting the positioning parameters corresponding to different AP combinations, and compares the positioning results. When the positioning results are different, an abnormal AP can be found; at the same time, no field measurement is required, which reduces the difficulty and cost of implementation.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a positioning optimization method, device and positioning server. Background technique [0002] In the existing WLAN (Wireless Local Area Network, wireless local area network), the WLAN terminal is positioned based on certain information of the AP (Access Point) (signal strength, transmission time of the AP signal to the terminal, etc.), such as based on the signal transmission time, Positioning methods based on signal transmission angle, based on signal strength value, based on probability distribution of signal strength, etc. Different methods all need to pre-record some original information of the AP, and perform subsequent positioning based on this information. [0003] However, in many scenarios, it is possible that the original information changes due to changes in the location of the AP or the change in the signal strength of the AP, and the positioning serve...
