面向智慧仓储物流的5G确定性网络技术研究与实践

Research and Practice of 5G Deterministic Network Technology for Smart Warehousing Logistics

当前,5G已经成为推动千行百业数字化转型发展的关键驱动力量,而工业互联网是5G的重要应用场景之一。传统网络尽力而为的转发方式无法保证网络时延及抖动有界,大量核心生产场景的时延敏感型业务对确定性时延的诉求日益增加。目前业内对于5G确定性网络的研究多以理论为主,针对工业场景下无线网络确定性时延保障的挑战,设计了一种多层次5G网络时延保障技术方案,基于5G核心网的确定性网络能力与无线URLLC特性,以提升网络的时延确定性。研究结果表明,该方案可以有效提升网络的时延确定性,能够为5G确定性网络在后续的大规模商用推广提供参考。

Currently,5G has become a key driving force in promoting the digital transformation and development of thousands of industries,and the industrial Internet is one of the important application scenarios of 5G.The best-effort forwarding method of conventional networks cannot guarantee bounded network latency and jitter,and a large number of latency-sensitive services in core production scenarios increasingly require deterministic latency.At present,the research on 5G deterministic networks in the industry is mostly based on theory.To cope with the challenge of deterministic delay guarantee of wireless networks in industrial scenarios,a multi-level 5G network delay guarantee technical solution is designed.It is based on the deterministic network capability of the 5G core network and the wireless URLLC feature,which can improve network delay certainty.The research results indicate that the technical solution can effectively improve the network delay certainty and provide a reference for the subsequent large-scale commercial promotion of 5G deterministic networks.
