摘要
目前,我国铁路移动通信专用网络(GSM-R)承载能力达到饱和,铁路各专业开始探索应用运营商公共通信网络推进铁路通信技术发展。我国铁路行业制定了以5G技术作为铁路下一代移动通信专用网络的发展路线,并提出统筹利用5G公网提升铁路智能化能力。基于5G技术特点,对铁路典型业务进行分析,提出铁路业务在移动通信网络中的分类承载方案,以及基于5G-R的铁路业务分级承载方案;最后,提出加快5G-R技术装备发展、采用多种移动通信网络承载铁路业务等建议,为铁路通信的相关研究提供参考。
Given the overwhelmed GSM-R network in China, the railway sector has turned to the public network to promote railway communication technologies. With 5G identified as the next-generation mobile communication network for railways, China has proposed a holistic approach for the building of intelligent railway via 5G public network. Based on the characteristics of 5G and the classic services of railway, the paper proposes a categorized carrying scheme for railway in mobile communication network, as well as a graded scheme based on 5G-R. The paper then advises to accelerate the development of 5G-R equipment and adopt diverse mobile communication networks to carry railway business, which are of reference to future studies on the issue.
