铁路5G-R网络技术特点及智能运维技术分析
Analysis of Technical Characteristics and Intelligent Operation and Maintenance Technology of Railway 5G-R Network
摘要
Abstract
The 5G-R network is a railway dedicated wireless network based on 5G technology.It uses key technologies such as software-defined network,network function virtualization,network slicing,all-IP networking and edge computing,to achieve the separation of network control and forwarding,and the decoupling of network software and hardware.Its network performance indexes include not only network coverage field strength,but also parameters such as system capacity,edge rate,network slicing management,time delay and packet loss rate,which makes its operation and maintenance more complicated than that of the GSM-R network.This paper firstly analyzes the status quo and existing problems of GSM-R system operation and maintenance,and then studies the network architecture and technical characteristics of the 5G-R network.It finally considers the technology development of artificial intelligence,big data and the Internet of Things,and proposes the key technologies required for the 5G-R intelligent operation and maintenance system.关键词
