摘　　要：5G确定性网络是支撑5G+工业互联网建设的重要一环,研究5G确定性网络的关键技术和落地方案具有重要意义。首先研究5G超高可靠低时延通信技术以及帧复制和消除技术,以降低传输时延并提高可靠性,其次在5G网络中探索循环队列转发技术,以消除端到端抖动,最后提出一种5G确定性网络落地方案,并在实际工业生产实验室中进行试验。试验结果表明,所提网络方案的综合性能优于现有网络方案,可以满足众多工业场景对5G确定性网络的需求。5G deterministic network is an important part to support the construction of 5G+Industrial Internet,and it is of great significance to study the key technologies and landing schemes of 5G deterministic network.Firstly,5G ultra-reliability low latency communication technology and frame replication and cancellation technology were studied to reduce transmission latency and improve reliability.Secondly,cyclic queue forwarding technology was explored in 5G networks to eliminate end-to-end jitter.Finally,a 5G deterministic network landing scheme was proposed and tested in actual industrial production labs.The test results show that the comprehensive performance of the proposed network scheme is better than the existing network schemes,and can meet the demand for 5G deterministic networks in many industrial scenarios.
