Embodiment 1

[0044] This embodiment provides an indoor social navigation system, such as figure 1 As shown, the system includes: a terminal 1, a target friend terminal 2, a positioning server 3, a location server 4, and a social application server 5; wherein,

[0045]Before the terminal 1 wants to perform the friend real-time navigation function, the location server 4 is used to calculate the distance between the terminal 1 and each friend terminal; The friend terminals (in the form of a list) are displayed on the interface of the terminal 1 .

[0046] Here, for example, the terminal 1 chooses to send a navigation request to the target friend terminal 2, and after the navigation request is approved, the terminal 1 forwards the navigation request to the location server 4.

[0047] After the navigation request is approved by the target friend terminal 2, the positioning server 3 is used to receive the first positioning sensor data sent by the terminal 1 and the first positioning sensor data...

Embodiment 2

[0129] Corresponding to Embodiment 1, when the real-time geometric coordinates of the terminal 1 can be determined, the check-in content can be released in the social network according to the geometric coordinates; specifically, when the terminal 1 receives a check-in request, the location server 4 Match the symbolic position of the check-in point of the terminal 1 in the geometric coordinates with the semantic information in the indoor spatial position model database to obtain the semantic position information of the check-in point; record the received dynamic text of the check-in Content and picture content are uploaded; at the same time, the semantic location of the check-in point is displayed and the location is displayed on the map. Here, the terminal 1 may access the social network through the wireless network established by Wi-Fi, or may enter the social network through the 3G / 4G network of the mobile operator.

[0130] Here, before publishing the check-in content, the ...

Embodiment 3

[0134] Corresponding to Embodiment 1, the location server 4 calculates the distance between the terminal 1 and each friend terminal; the social application server 5 displays the friend terminal (in the form of a list) according to the distance of the distance. After being displayed on the interface of the terminal 1, the terminal 1 is also used to send a tracking request to the target friend terminal 2 through the instant messaging server 6.

[0135] When carrying out friend tracking, since the access authority related to the user's location is involved, a tracking request mechanism is introduced, that is, the terminal 1 sends a friend tracking request to the target friend terminal through the instant communication server 6, and when the friend tracking request is allowed Afterwards, the terminal 1 sends the friend tracking request to the location server 4; after receiving the friend tracking request, the location server 4 sends the location server 4 a third preset cycle accord...

Abstract

The invention provides an indoor socializing navigation system. The system comprises a positioning sensor and a location server, wherein the positioning server is used for receiving first positioning sensor data transmitted by a terminal and second positioning sensor data transmitted by a target friend terminal, calculating the first geometrical coordinates of the terminal according to the first positioning sensor data and the second geometrical coordinates of the target terminal according to the second positioning sensor data, and storing the first geometrical coordinates and the second geometrical coordinates into a location database; the location server is used for acquiring indoor space model data, building an indoor space topological network, receiving a navigation request transmitted by the terminal, acquiring the first geometrical coordinates and the second geometrical coordinates from the positioning server according to the navigation request, and using a path searching algorithm to calculate the optimal navigation path in the indoor space topological network.

Description

technical field [0001] The invention belongs to the technical field of indoor location services, and in particular relates to an indoor social navigation system. Background technique [0002] With the development of mobile Internet and location-aware technology, location-based mobile social networking services have brought many conveniences to people's lives. The location attribute extends the mobile social network to reality, narrows the gap between the online virtual world and the offline real world, and improves the service effect of the social network. People can check-in and share information with location tags. multimedia content (geo-tagging content), etc.; at the same time, users can also expand social relationships based on spatial associations of locations. [0003] At present, location information in location-based mobile social networks is mainly obtained through positioning methods such as Global Positioning System (GPS, Global Position System), mobile base sta...
