摘要：近年来，时间敏感网络技术（TSN）的发展逐步引起工业界的广泛关注，其凭借低抖动、低延时、确定性传输等优势，为对传输时延有较高要求的应用场景提供了有力支撑，成为下一代工业网络承载技术的重要演进方向之一。为了在端到端的层面上满足某些垂直行业业务对低时延、高可靠的需求，5G网络在R15 URLLC的基础上对QOS、空口同步、头压缩等方面进行了增强，以满足TSN网络对于5G设备的严苛要求。首先从垂直行业需求入手，分析了5G网络与TSN融合的必要性，最后结合3GPP R16标准进展研究了TSN对于5G商用网络改造需求以及面临的挑战。

Abstract：Recent years, the development of Time Sensitive Network(TSN) technology has gradually attracted widespread attention from industry. Characterized by low jitter, low delay and deterministic transmission, TSN has provided strong support for scenarios with high requirements of transmission delay. It has become one of the important evolution directions of the next-generation industrial network bearer technology. In order to meet the low-latency and high-reliability requirements of vertical industry services at the end-to-end level, 5G network has enhanced QoS, air interface synchronization, header compression and other aspects to meet the strict requirements of TSN network for 5G equipment on the basis of R15 URLLC. Starting from the demands of vertical industries, this article analyzes the necessity of the integration of TSN and 5G network. The needs and challenges of TSN for 5G commercial network transformation has also been studied based on the 3GPP R16 standardization progress in the end.
