Problems solved by technology

[0002] At present, with the popularity of satellite positioning systems, people often use mobile phone map applications to find destinations. However, the existing positioning systems are suitable for finding destinations outdoors. If satellite positioning cannot be used in indoor environments, indoor positioning technology can be used as a The auxiliary positioning of satellite positioning solves the problem that the satellite signal is weak when it reaches the ground and cannot penetrate buildings

Embodiment 2

[0079] figure 2 is a flowchart of a positioning method shown according to an exemplary embodiment, such as figure 2 As shown, the positioning method is used in the positioning system where the terminal, the server, and the current micro base station are located, including the following steps 201-206,

[0080] In step 201, when the terminal camps on the current micro base station, it sends a query request for querying the location information of the current micro base station to the server.

[0081] In step 202, the server searches for the location information of the current base station according to the query request.

[0082] In step 203, the server sends feedback information carrying location information to the terminal.

[0083] In step 204, the terminal obtains the received signal parameters of the reference signal of the current micro base station.

[0084] In step 205, the terminal determines the distance between the current micro base station and the terminal accor...

Embodiment 3

[0088] image 3 is a flowchart of a positioning method shown according to an exemplary embodiment, such as image 3 As shown, the positioning method is used in the positioning system where the terminal, the server, and the current micro base station are located, and the method includes the following steps 301-310,

[0089] In step 301, the terminal acquires location information of the terminal through GPS.

[0090] In step 302, when the terminal cannot obtain the location information of the terminal through GPS, the micro base station where the terminal resides is detected.

[0091] In step 303, when the terminal detects that it is camped on the current micro base station, it acquires the identifier of the current micro base station.

[0092] In step 304, the terminal sends a query request for querying the location information of the current micro base station to the server, where the query request carries the identifier of the current micro base station.

[0093] In step 3...

Embodiment 4

[0103] Figure 4 It is a block diagram showing a positioning device according to an exemplary embodiment, and the device can be implemented as part or all of electronic equipment through software, hardware or a combination of the two. Such as Figure 4 As shown, the positioning device includes:

[0104] The receiving module 401 is configured to receive the location information of the current micro base station where the terminal resides sent by the server;

[0105] The first acquiring module 402 is configured to acquire the received signal parameters of the reference signal of the current micro base station;

[0106] A determining module 403, configured to determine the terminal's own location information according to the signal parameters and the location information.

[0107] In one embodiment, such as Figure 5 As shown, the receiving module 401 includes:

[0108] The sending submodule 4011 is configured to send a query request for querying the location information of ...

Abstract

The invention provides a locating method and apparatus. The method comprises the following steps: receiving the position information of a current micro base station where a terminal resides sent by a server; obtaining a signal parameter of a reference signal of the current micro base station; determining the own position information of the terminal according to the signal parameter and the position information. By adoption of the technical scheme, when the position of the terminal cannot be determined through the GPS, the position of the terminal is located via the position information and the signal parameter of the micro base station, so that an accurate locating function can be achieved at various corners.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a positioning method and device. Background technique [0002] At present, with the popularity of satellite positioning systems, people often use mobile phone map applications to find destinations.
