深圳城际铁路5G公专网应用研究

Application of 5G Public-Private Network for Shenzhen Intercity Railway

结合深圳城际铁路特点,对包括列车运行控制和视频监控下载等不同业务的无线通信数据传输需求进行了分析,提出根据业务的安全性和带宽需求特点分别采用不同的无线通信网络的建议。同时,针对“高带宽传输”和“多设备接入”需求的车地无线通信网络,在对比分析了轨道交通行业内主流无线通信技术的基础上,结合5G公专网的方案特点和测试情况,提出了适合轨道交通行业的5G公专网应用模式。另外,结合“智慧城际”和“云边协同”的发展要求,提出了适合深圳城际铁路的5G混合专网优化方案,并探讨了依托5G高传输速率和前端边缘计算节点的部分智慧应用和相应的数据交互流程,以满足各类智慧业务高实时、高性能的要求,提升城际铁路的客服和运维能力。

According to the characteristics of Shenzhen intercity railway,this paper analyzed the wireless communication data transmission requirements of different services including train operation control and surveillance video download.It proposed to adopt different wireless communication networks according to the security and bandwidth requirements of the services.For the train-ground wireless communication network requiring“high bandwidth transmission”and“multiple equipment access”,based on the comparative analysis of the mainstream wireless communication technology in rail transit,the paper proposed the suitable application mode of the 5G public and private network for the rail transport industry according to the characteristics and test of the 5G public and private network.It put forward a 5G hybrid private network optimization scheme suitable for the Shenzhen intercity railway in combination with the development requirements of“smart intercity”and“cloud edge collaboration”.In addition,it discussed some applications and data interaction process based on 5G high transmission rate and front-end edge computing nodes to meet the requirements of high real-time and high performance of smart businesses and improve the customer services and maintenance capabilities of the intercity railway.
