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

Embodiment Construction
[0040] Embodiments of the present application are described below in conjunction with the accompanying drawings.
[0041] Generally, the Wi-Fi devices in the building area are installed at fixed locations in the building, so the distribution of network positioning data scanned by the Wi-Fi devices is as follows: figure 1 As shown, the location of a Wi-Fi device can be estimated by using the multi-identified location points of these network location data, and a Wi-Fi location library can be generated, which is then used to provide network location services for terminal devices in the building area.
[0042] The data required for location mining of Wi-Fi devices is generated based on network positioning data (such as GPS signals) reported by terminal devices around Wi-Fi devices, and most terminal devices in network positioning scenarios are located in areas that cannot receive GPS signals For example, indoors, between buildings, etc., so the distribution of GPS data has a certa...

Embodiments of the present application disclose a positioning method and a related apparatus, which relate to the field of maps, such as the positioning of terminal equipment between buildings. Based on a plurality of network positioning data of the wireless device in the building area, a signal characteristic map reflecting the signal distribution of the wireless device is determined. According to the signal characteristic map and the building distribution information of the building area, the target building where the wireless device is located is determined from the building area, the location of the target building is taken as the actual location of the wireless device, and a binding relationship is established. Since the building distribution information accurately identifies the location, scope and distribution of the buildings included in the building area, it can effectively eliminate unreasonable excavation positions in the process of determining the target building based on the building distribution information, which can calibrate the network. The function of the position mining error of the positioning signal realizes the accurate binding of the wireless device and the building, and the accurate binding relationship 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...
