摘要
5G赋能行业应用是当前产业各方关注的焦点,工业业务需要由具有确定性特征的网络进行承载,而无线网络由于其信道特性,成为影响工业业务确定性传输的最大挑战。因此,5G与时间敏感网络的协同传输被学术界广泛关注,如何提升5G网络承载业务的确定性成为研究的重点。以3GPP标准的5G-TSN协同传输为基础,重点对5G TSN桥接网络架构、支持TSN的5G网元功能、5G空口调度增强策略等进行了阐述和分析;同时基于5G-TSN协同传输架构,对时间敏感业务流跨5G、TSN域的端到端数据传输流程进行了研究。
5G enabling vertical applications is drawing attentions from all parties in the industry. However,industrial services should to be carried upon deterministic networks,and wireless network becomes the biggest challenge affecting the deterministic transmission of industrial traffic due to its random characteristics of radio channel. In this context,the cooperation transmission of5G and time-sensitive networking has been widely concerned by the academic community,and how to improve the deterministic of 5G network has become hot research topics. Based on 5G-TSN cooperative transmission defined by 3GPP,it focuses on the 5G TSN bridge network architecture,the functions of 5G network elements supporting TSN and scheduling enhancements in 5G radio access networks. Furthermore,based on 5G-TSN cooperative transmission architecture,the end-toend data transmission process across 5G and TSN domain is studied and presented.
