摘要

5G 确定性网络是目前产业界正在积极推动的全新工业通信技术。为了逐步实现确定性传输，3GPP引入了时间敏感通信技术，与超可靠低时延通信技术相比，进一步在时延抖动和时间同步方面对5G网络进行了增强，从而实现端到端的时间敏感通信服务。介绍了时间敏感通信技术特点和标准进展，时间敏感通信技术以时间敏感网络与5G网络融合的网络架构为基础，通过精确时间同步机制提高时间同步精度，通过服务质量和调度增强机制降低业务时延、提高传输可靠性，通过以太网头压缩技术提高传输效率。

Abstract

5G deterministic network is a new type of industrial communication technology vigorously promoted by the international industry.3GPP had introduced the time-sensitive communication technology to facilitate deterministic transmission.Compared with ultra-reliable and low-latency communication technology

time-sensitive communication technology further enhanced the 5G network in terms of delay jitter and time synchronization to realize the end-to-end time sensitive communication.Characteristics of time sensitive communication technology were analyzed.Based on the time-sensitive networking and 5G network converged architecture

the time-sensitive communication technology reduces the time synchronization error through the accurate time synchronization mechanism.Additionally

the scheduling enhancement mechanism was introduced to reduce the transmission delay.Furthermore

the Ethernet header compression mechanism was proposed to improve transmission efficiency.
