A method and system for base station positioning based on nb-iot network

Abstract

The present invention proposes a base station positioning method and system based on the NB-IoT network. The method includes: connecting a base station positioning terminal with a device, and the base station positioning terminal is connected to the NB-IoT network; according to the unique code of the device sent by the base station positioning terminal , obtain the virtual positioning position of the device; if the device is the first online device, calculate the virtual positioning position; when the new positioning of the device is obtained, compare it with the virtual positioning position, if the difference between the actual positioning position and the virtual positioning position If the distance does not exceed the set threshold, the actual position of the recording device has not changed; if the distance between the actual positioning position and the virtual positioning position exceeds the set threshold, it is determined that the actual position of the device has changed. According to the actual positioning position and the virtual positioning position vector Calculate the direction and distance of the device position change; locate the device according to the direction and distance of the device position change.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a base station positioning method and system based on an NB-IoT network. Background technique [0002] In the process of product sales, in many cases, we need to know the general location information of the moving equipment. If the location information is not required to be particularly precise, the base station positioning solution will be used, that is, the operation obtained when registering the network with the help of the communication module. The unique code of the operator's base station is transmitted to the server through the operator's network, and then correlated with the base station coordinates provided by the operator to confirm the general location information of the device. [0003] For example, in the prior art, a positioning method and device that can correct the positioning of a base station have been proposed: the device mainly includes a comp...

AI Technical Summary

Problems solved by technology

[0018] In summary, the use of NB-IoT network to obtain base station information and transmit base station information is limited by the capabilities of network operators and the capacity of NB-IoT network base stations. When there are a large number of accesses in a range, it is limited by base station access The communication speed of some devices will be very slow, or even unable to access, and there will be position drift, resulting in low positioning accuracy and unable to achieve the desired effect in practical applications.

Therefore, the existing technology can only rely on the positioning information data fed back by the operator, and cannot fundamentally solve the problem of low positioning accuracy until the operator's capabilities and the number of base stations are improved
