Antenna Reverse Detection Method and Device

Abstract

The present application provides a method and device for detecting reverse connection of an antenna, which relate to the field of mobile communication and can accurately and quickly detect whether an antenna is connected reversely. The method includes: acquiring an interoperability record of the second network cell and at least one first network cell, determining the matching first network cell of the second network cell according to the interoperability record, and combining the preconfigured first network cell of the second network cell Cell, determine whether the antenna of the second network cell is reversed. Wherein, the interoperability record is a record that the terminal leaves the second network cell and accesses the first network cell, and the matching first network cell is the first network cell with the highest access probability after the terminal leaves the second network cell.

Description

technical field [0001] The present application relates to the field of mobile communications, in particular to a method and device for detecting reversed connection of an antenna. Background technique [0002] In the mobile communication network, the fourth generation mobile communication technology (4G) network inherits the cellular structure of the third generation mobile communication technology (3G) network. In an example, the networking mode adopted by the 4G network is as follows: three cells are deployed at one physical site. see figure 1 , on the same physical site, 3G cells and 4G cells are usually deployed at the same time. During network planning, the direction of the 3G sector and the 4G sector are usually consistent to ensure that each 3G cell and the corresponding 4G cell cover the same geographical area. Therefore, the coverage areas of the 3G cell and the 4G cell are the same, such as figure 1 shown. At this time, see figure 1 , in a 4G base station, the...

AI Technical Summary

Problems solved by technology

In this way, when the antenna of a 4G cell is reversed during actual deployment, the coverage area of ​​the 4G cell may be different from the pre-planned coverage area

[0003] The traditional way of diagnosing community antenna reverse connection is: manual road test to determine whether there is community antenna reverse connection; The antenna of the cell is reversed, and the above two diagnosis methods have problems such as long time-consuming, high cost, and not suitable for large-scale diagnosis

In the prior art, there are also diagnostic methods based on data such as handover relations of adjacent cells in the 4G network and measurement reports (MR), but iterative processing of a large amount of data is required to determine whether the antenna of the cell is reversed, and the calculation complexity is high. The amount of data is huge, and the area with a high docking reverse rate has poor diagnostic accuracy
