Positioning method and related device

Abstract

The embodiment of the invention discloses a positioning method and a related device, and relates to the field of maps, such as terminal equipment positioning between buildings. A signal feature map representing a signal distribution condition of a wireless device is determined based on a plurality of network positioning data of the wireless device in a building area. And a target building where the wireless device is located is determined from the building area according to the signal feature map and the building distribution information of the building area, the position of the target building is taken as the actual position of the wireless device, and a binding relationship is established. Since the building distribution information accurately identifies the positions and the ranges of the buildings included in the building area and the distribution condition of the buildings in the building area, unreasonable excavation positions can be effectively eliminated in the target building determination process based on the building distribution information, and the effect of calibrating the position excavation error of the network positioning signal is achieved; accurate binding of the wireless device and the building is achieved, and the accurate binding relation improves the positioning accuracy of the terminal device in the building area.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a positioning method and a related device. Background technique [0002] The user can check his current location by using the positioning service provided by the mobile terminal. Commonly used positioning methods include Global Positioning System (Global Positioning System, GPS) positioning or network positioning. When the user is in an open area, the GPS signal is mainly used to realize the positioning service. When there are a lot of obstructions around the user, such as in a building, the GPS signal of the mobile terminal is weak or even absent. At this time, it is necessary to use the network positioning method to provide the user with positioning service. [0003] At present, it mainly matches the Wi-Fi location library based on the wireless device identifier carried in the Wireless Fidelity (Wi-Fi) signal provided by the mobile terminal. Since the Wi-Fi location l...

Problems solved by technology

[0005] It can be seen that related technologies strongly rely on the correlation between the name of the SSID and the name of the building when establishing the Wi-Fi location database. Once the owner of the wireless device modifies the name of the SSID to reduce the correlation with the name of the building, it will be difficult to determine the location. The correspondence may determine the wrong correspondence, thereby reducing the quality of the Wi-Fi location library, and a low-quality Wi-Fi location library will provide inaccurate positioning results for mobile terminals in the building
