Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] System embodiment

[0026] In the target service area with high environmental complexity and high positioning accuracy requirements, such as indoors in dense urban areas (such as central business districts, etc.) and large public places (such as large shopping malls, airports, exhibition halls, hospitals, etc.) In the environment, the dynamic characteristics of the environment are very strong, and the invalidation of fingerprint data is relatively fast. Frequently collecting and updating the fingerprint database in batches is not only costly but also inefficient. Therefore, the present invention proposes a wireless network positioning system for this type of area, such as figure 1 As shown, a reference network 50 composed of several receiver devices is deployed in the target service area with a relatively small density (small density means that the signal r...

Abstract

The invention discloses a wireless network location method, device and system. The method comprises A. requesting monitoring data of a receiver device in a reference network on terminal visible base station signal strength from a reference network central server according to received terminal location request information; and B. locating a terminal according to the monitoring data returned from a dynamic fingerprint prediction model and the reference network central server. The wireless network location method, device and system can timely monitor and capture dynamic change trends of signal strength in a neighboring environment at the receiver device by introducing the reference network composed of a reference receiver device, and enables dynamic signal strength data (namely dynamic fingerprint information) to be used for on-line real-time location. Influences on positional accuracy of complex and dynamically-changed environmental factors on a traditional fingerprint location method based on a static fingerprint data base are weakened to a large extent.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a wireless network positioning method, device and system. Background technique [0002] The fingerprint positioning technology based on signal strength in the existing wireless network location service is used to solve the technical problem of reducing the cost of fingerprint data collection under the premise of maintaining fingerprint data update to ensure fingerprint positioning performance in the fingerprint positioning system. [0003] Fingerprint positioning technology is a positioning technology based on characteristic parameters such as signal strength received by a positioning terminal in a wireless network. Generally, fingerprint positioning technology can be divided into two stages from the perspective of processing steps: offline sampling and online positioning. [0004] In the offline phase, the sampling terminal receives the identification information of th...
