摘　　要：通过分析垂直行业的需求特性,结合5G高可靠与低时延通信(Ultra-Reliable Low Latency Communication,URLLC)和时间敏感网络(Time Sensitive Networking,TSN)相关服务质量(Quality of Service,QoS)标准的最新进展,设计垂直行业基于扩展5G服务质量标识符(5G QoS Identifier,5QI)的QoS解决方案。针对URLLC业务的低时延特性,分析URLLC QoS监测功能和时延计算的具体流程。针对URLLC业务的高可靠特性,分析核心网协议数据单元(Protocol Data Unit,PDU)会话的冗余设计。分析5G系统作为一个桥透明集成到一个TSN网络中的网络架构、业务调度模型和业务辅助标识信息。通过对URLLC核心网的QoS方案、基于TSN的QoS方案进行系统分析,设计垂直行业应用满足QoS特性的解决方案。This paper analyzes the requirements of the vertical industry.With the latest development of 3 GPP QoS standards on URLLC and TSN,the QoS solutions based on pre-configured 5 QIs are designed.For the low delay characteristics of URLLC service,this paper analyzes the QoS monitoring function and the process of delay calculation.For the high reliability of URLLC service,the redundancy design of PDU session in core network is analyzed.This paper analyzes the network architecture,service scheduling model and TSC assistance information of 5 G system integrated into a TSN network as a bridge.Through systematic analysis of URLLC core network’s QoS scheme and TSN-based QoS scheme,solutions for vertical industry applications that meet QoS characteristics are designed.
