摘要
在调研铁路下一代移动通信系统业务需求,分析铁路安全保障业务、铁路运输管理业务和乘客信息服务等三类业务的基础上,提出了铁路下一代移动通信业务发展规划;对比讨论了铁路下一代移动通信系统的5种备选技术,提出铁路下一代移动通信接入网应采用LTE技术;探讨了铁路下一代移动通信系统的发展思路,并给出了LTE-R的发展规划建议。
Based on an investigation of the service requirement of the next generation of GSM-R as well as a analysis of three categories of services including railway safety guaranty, railway transportation management and passenger information, we put forward a service development planning for the next genera- tion of GSM-R. The paper also compares five kinds of alternative technologies of the next generation of GSM-R and proposes adopting LTE technology. Furthermore, we explore the development ideas of the next generation of GSM-R and give some suggests on the development planning of LTE-R.
