中文摘要：
高速铁路自诞生起即伴随着车地移动通信的承载需求,其中一部分业务承载需求来源于高速列车的列车控制与列车调度,这是高速列车必不可少的重要组成部分,另一部分业务来源于车上的旅客,这些是满足旅客服务质量需求的重要标志之一。特别是在移动互联网时代,上网需求已成为人们生活的重要组成部分。该文总结了世界各国高速铁路移动通信发展的重要历程,特别是支持旅客信息接入的车地移动通信技术发展现状,从移动通信技术发展的趋势讨论高速铁路移动通信技术发展的趋势,包括与公众移动通信技术发展的关系,展望未来高速铁路移动通信的一些关键技术,并提出了一些具体建议,从而给该领域相关的研究人员提供一些参考。
英文摘要：
Since the birth of the high-speed railway, it is growing with the mobile communication demand of train to wayside. One part of traffic load demand is from the train control and train dispatching, which is an important part of the high-speed railway. And another part of the traffic load is from the passengers, which is one of the important Key Performance Indexes（KFIs） that can satisfy the requirement of passenger service quality. Especially in the era of mobile Internet, the Internet demand becomes an important part of people’s daily life. This paper summarizes the important processes of the development of mobile communications for high-speed railway over the world, especially the present mobile communication technologies to support the passengers’ information access from train to Internet. Based on the development trend of mobile communication technology, the development trend of its counterpart in high-speed railway is discussed, including its relationship with the development of public mobile communication technology. Some future key technologies, including some detailed suggestions, of mobile communications for high-speed railway are prospected, which may provide some references for the relevant researchers in this field.
