提升高铁隧道5G网络覆盖效果的研究

Research on Improving 5G Network Coverage in High Speed Rail Tunnels

随着我国高速铁路的不断建设,高铁通向神州大地的各个角落,形成四通八达高铁网络。我国地形复杂,高铁必然存在大量的隧道里程,为了满足人们日常出行的通信网络需求,国内电信运营企业在隧道内进行了5G网络覆盖建设。由于高铁运行特性、高铁车体特性和隧道内的安全性要求,导致5G网络在隧道内的覆盖不能满足覆盖需求;同时高铁上高端移动用户集中,数据业务发生频繁,是5G网络需要重点覆盖的场景。文章通过分析高铁覆盖存在的问题,在保证高铁隧道运营安全性的情况下,通过一系列补充拓展,尽可能地提升5G网络的信号覆盖,以满足网络覆盖需求。

With the continuous construction of high-speed railways in our country,high-speed railways lcad to various corncrs of the land of China,forming an interconnccted high-speed railway network.China's terrain is complex,and high-specd rail inevitably has a large number of tunnel mileage.In order to meet the communication network needs of people's daily travel,domestic telecommunications operators have carried out 5G network coverage construction in the tunnels.Due to the operational characteristics of high-speed trains,the characteristics of highspeed train bodies,and safety requirements in tunnels,the coverage of 5G networks in tunnels cannot meet the coverage requirements;At the same time,the concentration of high-end mobile users on high-speed rail and frequent occurrence of data services are key scenarios that 5G networks need to cover.This article analyzes the problems of high-speed rail coverage and,while ensuring the safety of high-speed rail tunnel operation,through a series of supplementary expansions,strives to improve the signal coverage of 5G networks as much as possible to meet network coverage requirements.
