Problems solved by technology

However, the angle measurement used in this method is completed on the side of the 5G base station, that is, the positioning server needs to connect to the 5G base station and obtain the data generated by the base station. In the actual application process, technical and management problems in data transmission will inevitably be encountered. It is difficult for the three parties to obtain the consent of the operator to directly obtain the data on the base station side. At the same time, to obtain such data related to the operation of the base station, the support and assistance of the base station equipment manufacturer must be obtained. In view of the possibility of leaking key technical information of the equipment, it is generally difficult to obtain consent.
Therefore, this method does not have practical operability. At the same time, because the measurement information is limited to the signal DOA angle information, the scope of application of the method and the positioning accuracy that can be realized in theory are also limited.

Embodiment Construction

[0050] In order to understand the content of the present invention more clearly, it will be described in detail with reference to the drawings and embodiments.

[0051] like figure 1 , figure 2 Shown is a schematic diagram of a preferred structure of the positioning system based on 5G signal fingerprints of the present invention, including a terminal, a fingerprint training server and a positioning server. Among them, such as figure 1 The structure of the fingerprint training part of the system is shown. The terminal connects to the 5G base station for communication and generates signal measurement values ​​and transmits them to the fingerprint training server. The positioning fingerprint is obtained through artificial neural network training and then deployed to the positioning server; figure 2 The structure of the real-time positioning part of the system is shown in the figure. The signal measurement value obtained by the real-time measurement of the terminal is transmit...

Abstract

The invention relates to a positioning method and device based on 5G, and the method comprises the steps: obtaining a signal measurement value needed by positioning from a terminal side, making a signal fingerprint through employing the signal measurement value generated by a terminal in a 5G communication authorization frequency band in a communication process, and carrying out the terminal positioning, thereby achieving the very good realizability. Existing 5G base station resources can be fully utilized to realize multi-terminal positioning capability with sub-meter-level precision in a specific range, extra signal equipment investment is not needed, signal interference is little, and the positioning capability is high.

Description

technical field [0001] The present invention relates to the technical field of communication positioning, in particular to a 5G-based positioning method and device. Background technique [0002] With the popularization of smart mobile terminals and the continuous development of various services based on mobile smart terminals, the demand for terminal location positioning is becoming more and more important, and it has become an indispensable functional component in terminal equipment. [0003] The satellite positioning method and the communication base station triangulation positioning method are most widely used in the prior art. Among them, the satellite positioning method relies on satellite signal feedback to locate the terminal, and the positioning accuracy in the civilian field is low, and it is especially vulnerable to vertical occlusion affecting the positioning signal transmission, resulting in positioning failure; the communication base station triangulation positi...
