Problems solved by technology
[0004] However, satellite positioning technology cannot be used in an indoor environment. For example, satellite positioning technologies such as the Global Positioning System (GPS) and Beidou cannot be used in an indoor environment. Wireless Fidelity (Wireless Fidelity, WIFI), Radio frequency identification (Radio Frequency Identification, referred to as RFID), Bluetooth and other means to help achieve
[0005] The resulting problem is that when the user enters the indoor environment from the outdoor environment, the terminal cannot automatically change the positioning method, which may easily cause positioning failure

The invention discloses a method and system for indoor and outdoor positioning switching, a terminal and a positioning application platform, and relates to the field of mobile Internet positioning. The method includes collecting the number of GPS visible satellites and the RSSI of the WIFI access point; reporting the number of GPS visible satellites and the RSSI of the WIFI access point to the positioning application platform, so that the positioning application platform can jointly judge that the current environment of the terminal is outdoor according to the reported information Environment, indoor environment or occlusion environment, and select the corresponding positioning method according to the current environment of the terminal; the terminal starts positioning according to the positioning method selected by the positioning application platform. The invention realizes the seamless switching of indoor and outdoor positioning, and improves the positioning success rate when the indoor and outdoor environments change.
Description
technical field [0001] The present invention relates to the field of mobile Internet positioning, in particular to a method and system for indoor and outdoor positioning switching, a terminal and a positioning application platform. Background technique [0002] With the widespread application of third-generation networks and smart phones, location-based services (Location Based Service, referred to as LBS) are being accepted by more and more users under the strong promotion of the mobile Internet. Maps and location navigation. [0003] At present, most of the location-based services provided on mobile phones are based on outdoor environment positioning and navigation, surrounding search and other services, but users' demand for indoor environment positioning services continues to grow. Indoor environments such as museums can also enjoy positioning services. [0004] However, satellite positioning technology cannot be used in an indoor environment. For example, satellite po...
