面向6G演进的确定性信息物理系统架构研究

Research on deterministic Cyber-Physical Systems architecture for 6G evolution

确定性技术是满足6G新兴业务确定性转发要求的重要研究内容。信息物理系统(Cyber-Physical System,CPS)作为工业4.0的核心系统,其确定性保障对于生产的高效稳定和服务的安全可靠至关重要。围绕以工业互联网为代表的CPS系统的确定性需求,提出一种基于确定性网络技术的CPS系统架构,包括确定性通信网络和确定性系统组件。在此基础上,面向低时延云化控制场景、高可靠移动控制场景和大带宽闭环控制场景三类典型用例对所提的系统架构进行细化设计,并对系统的时延、抖动、可靠性、带宽等指标的确定性进行分析。

Deterministic technology is an important research content to meet the deterministic forwarding requirements of 6G emerging services.As the kernel system of Industry 4.0,the deterministic guarantee of Cyber-Physical System(CPS)is of vital importance for the efficiency and stability of production and the safety and reliability of service.Focusing on the deterministic requirements of CPS represented by industrial Internet,a CPS system architecture based on deterministic network technology is proposed,including deterministic communication network and deterministic system components.On this basis,the proposed system architecture is detailed designed for three typical use cases:low delay cloud control scenario,high reliability mobile control scenario and large bandwidth closed-loop control scenario,and the determinacy of delay,jitter,reliability and bandwidth is analyzed.
