LTE高速铁路场景专网分析

【】在京津冀一体化的大背景下,高速铁路的建设和运营将为三地交通运输提供有力保障。同时,中国高铁走出国门的决策出台为国家经济开启了新的增长点,由此可见高速铁路在国家经济发展中的比重不断增加。随之而来的无线通讯对高铁的覆盖,特别是高速数据业务的需求变得与日俱增。而LTE专网为高铁场景下的高速数据业务提供了良好的无线通讯管道。本文首先对LTE专网优化难点进行了介绍,随之对关键参数与下载速率的相关性基于海量数据进行了分析。同时,基于LTE专网优化难点从站址的选择,组网的规划和邻区设置等方面提出了优化建议。最后,对未来的高铁覆盖提出了两种覆盖模型展望,其中文章明确指出基于载波聚合技术的车载分布系统将更能为终端用户提供较好的业务体验。

Analysis of LTE high speed railway scene network

The construction and operation of High-speed railway will be offer more traffic and transportation guarantee within the background of the Beijing Tianjin Hebei integration. Meanwhile, the national economy opens a new growth point based on the Chinese High-speed Rail abroad policy decisions. The proportion of the high speed railway is increasing in the development of national economy. Coverage of wireless communication with the High-speed Rail, especially the high-speed data services keep growing with each passing day. While the LTE network provides wireless communication pipeline is good for high-speed data High-speed Rail scenarios of the business. This paper first introduced the LTE network optimization problems, with the correlation on the key parameters and download rate based on mass data were analyzed. At the same time, this paper provides the optimization suggestion in some aspects which site selection, network planning and neighbors setting based on the LTE network optimization problems. Finally, cover the proposed two kinds of coverage model of High-speed Rail prospect future, the paper pointed out that the technology of carrier aggregation distribution system will provide better service for experience of terminal users.
