LTE-R混合组网中既有通信资源利用方案

Utilization Scheme of Existing Communication Resources in LTE-R Hybrid Networking

从技术、产业和国际发展趋势三个方面分析了LTE-R将是最有可能的铁路下一代移动通信技术;从核心网、无线网和承载网三个方面提出了GSM-R与LTE-R混合组网中对机房、电力、传输、漏缆等既有通信资源利用的建议,有利于降低混合组网的建网和维护成本。

Through analyzing from the three aspects of technology,industry and international development trend,LTE-R would be the most potential next generation of railway mobile communications technology.In view of core network,and wireless network and bearer network,it is proposed how to utilize existing communications resources in a hybrid network of GSM-R and LTE-R,including equipment room,and power,and transmission,and leak cable,so as to reduce the cost in the set-up and maintenance of hybrid network.
