Embodiment Construction

[0020] The present invention proposes an indoor positioning method based on outdoor assistance, as shown in Figure 1. This method uses the GPS information of users who hold smartphones outdoors, and outdoor users can generally obtain location information with higher accuracy. This method also uses the function of a smartphone: the current smartphone can generally be used as a hotspot, when the hotspot is turned on After the function is enabled, other mobile phones can detect the hotspot and connect to it. In addition to providing communication, this function can also calculate the distance information between two users based on the intensity information of the hot spot. Finally, through the interaction between indoor and outdoor users, the indoor user calculates the current coordinate information of the user based on the data information of multiple points. This method provides a new idea of ​​an indoor positioning method, making full use of the current popularization of smar...

Abstract

The invention provides an outdoor-assisting indoor positioning method in LBS (Location Based Service). The method utilizes GPS (Global Positioning System) information of an outdoor user handholding a smart phone, so that the outdoor user can obtain higher-precision location information generally. The method also utilizes one function of the smart phone: the traditional smart phone is generally used as a hot spot, and after the hot spot function is started up, other phones can detect the hot spot and connect the hot spot. Except for communication, the function can also calculate the distance between two users according to the intensity information of the hot spots. Finally, an indoor user can calculate the current coordinate of the user according to the data information of a plurality of points through the interaction between the indoor and outdoor users. The method provides a new idea of an indoor positioning method, and fully utilizes the popularity of the current smart phones. The method can be used as an auxiliary indoor positioning technology.

Description

technical field [0001] The invention belongs to the technical field of mobile Internet applications, in particular to a method for determining a user's indoor location in a location-based service (LBS). Background technique [0002] With the rapid development of high-tech industries such as computer technology and communication technology, social productivity has developed rapidly and social production efficiency has been significantly improved. In recent years, the combination of Internet and mobile communication technology has provided many value-added services for mobile users, and location-based services (Location-Based Service, LBS) are more and more popular. LBS is a mobile information application service that provides services to users based on their location. It widely supports applications that require geospatial information, and supports information query, emergency services, road navigation, asset management, personnel tracking, positioning advertisements, etc., ...
