Antenna downward inclination angle adjusting method and device based on LTE network

Abstract

The invention discloses an antenna downward inclination angle adjusting method and device based on an LTE network. The antenna downward inclination angle adjusting method and device based on the LTE network are used for solving the problems that in the prior art, due to manual intervention, resources are wasted, data are inaccurate, antenna downward inclination angles are arranged unreasonably, and the reliability of wireless transmission cannot be ensued. The method comprises the steps that a cell weak coverage coefficient and a cell overlapping coverage coefficient of each cell are obtained through simulation results of a propagation model, problem cells are screened out according to the cell weak coverage coefficients and the cell overlapping coverage coefficients of all cells, and lastly, the antenna downward inclination angles of all the problem cells are adjusted in sequence according to priorities of all the problem cells and the coverage areas of all the cells. In this way, the manual intervention is reduced, the resources are saved, the data are obtained through simulation calculation instead of experience values, the optimization process is simplified, optimization efficiency is improved, the accuracy of the antenna downward inclination angle is improved, and transmission reliability is ensured.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for adjusting an antenna downtilt angle 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 personnel in the communication field. In wireless transmission, it is necessary to avoid the weak coverage of the cell and the interference caused by the overlapping coverage of the cell. question. In a Long Term Evolution (LTE) network, the coverage radius of an outdoor cell is directly related to the downtilt angle of the antenna. An unreasonable downtilt angle setting of the antenna may lead to problems such as weak cell coverage and overlapping coverage. Therefore, it is necessary to accurately set the downtilt angle of the antenna. [0003] At the current network planning stage, there are two situations for ...
