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

Abstract

The present invention provides a method and system for triangulating a base station based on an NB-IoT network. The method includes: acquiring the real-time positioning and virtual position of the device, calculating the distance between the real-time position and the preset real position of the device, and judging the distance and the preset real position of the device. Set the relationship of the position threshold, and further calculate the offset distance between the real-time position and the virtual position point, compare the minimum offset distance with the system threshold and the minimum virtual threshold, and determine the number of virtual positions, and correct the virtual position of the device. The device performs accurate positioning; the invention can correct the positioning data by algorithm to improve the positioning accuracy, avoid the positioning drift phenomenon caused by the number of base stations, base station signals, etc., has strong versatility in application, and can maintain the base station positioning function Low power consumption, no external auxiliary equipment is required, and equipment cost is effectively reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a triangulation method and system for base station positioning based on 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 mobile device. If the location information is not required to be particularly accurate, we will use the base station positioning solution, that is, the operating information 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 the base station have been proposed: the devic...

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
