An antenna downtilt adjustment method and device based on an LTE network

Abstract

The invention discloses an antenna downtilt angle adjustment method and device based on an LTE network, which are used to solve the problem of resource waste caused by manual intervention and inaccurate data in the existing antenna adjustment technology. It is unreasonable and cannot guarantee the reliability of the wireless transmission of the system. The method includes: calculating the weak coverage coefficient and overlapping coverage coefficient of each cell through the simulation results of the propagation model, and screening out problem cells according to the weak coverage coefficient and overlapping coverage coefficient of each cell, and finally according to the problem cell The priority of each cell, and the coverage area of ​​each cell, adjust the antenna downtilt angle for each problem cell in turn. In this way, manual intervention is reduced, which saves resources, and the obtained data is calculated by simulation rather than empirical values, which simplifies the optimization process and improves the optimization efficiency. At the same time, the accuracy of the antenna downtilt angle is improved to ensure reliable transmission. sex.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for adjusting the downward tilt angle of an antenna based on an LTE network. Background technique [0002] In recent years, with the development of communication technology, the reliability of wireless transmission has been paid more and more attention by people in the communication field. In wireless transmission, it is necessary to avoid the problem of weak cell coverage and avoid interference caused by overlapping coverage of cells. problem. In the Long Term Evolution (LTE) network, the outdoor cell coverage radius is directly related to the antenna downtilt. The unreasonable antenna downtilt angle setting may cause problems such as weak cell coverage and overlapping coverage. Therefore, it is necessary to accurately set the antenna downtilt angle. [0003] At the current network planning stage, there are two scenarios for the antenna downtilt planning...
