Problems solved by technology

[0004] However, satellite positioning technology cannot be used in indoor environments. For example, satellite positioning technologies such as Global Positioning System (GPS) and Beidou cannot be used in indoor environments, and wireless fidelity (Wireless Fidelity, WIFI) is needed. , 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

Abstract

This invention discloses a method and a system for positioning switching between the indoor and the outdoor, a terminal and a positioning application platform, which relate to the mobile Internet field. The method comprises steps of collecting quantity of GPS visible satellites and RSSI of WIFI accessing points, reporting the GPS visible satellite quantity and RSSI of WIFI accessing points to a positioning application platform in order to provide convenience to the positioning application platform to determine what environment the terminal is positioned (outdoor environment, indoor environment and shielding environment) by combining the report information, choosing the corresponding positioning mode according to the environment where the terminal is positioned, and starting positioning by the terminal according to the positioning mode chosen by the positioning application platform. This invention realizes seamless switching between the indoor positioning and the outdoor positioning and improves the positioning success rate when the indoor environment or the outdoor environment changes.

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 indoor environments. For example, satellite posi...
