摘要： 近年來(lái)，時(shí)間敏感網(wǎng)絡(luò)技術(shù)（TSN）的發(fā)展逐步引起工業(yè)界的廣泛關(guān)注，其憑借低抖動(dòng)、低延時(shí)、確定性傳輸?shù)葍?yōu)勢(shì)，為對(duì)傳輸時(shí)延有較高要求的應(yīng)用場(chǎng)景提供了有力支撐，成為下一代工業(yè)網(wǎng)絡(luò)承載技術(shù)的重要演進(jìn)方向之一。為了在端到端的層面上滿足某些垂直行業(yè)業(yè)務(wù)對(duì)低時(shí)延、高可靠的需求，5G網(wǎng)絡(luò)在R15 URLLC的基礎(chǔ)上對(duì)QOS、空口同步、頭壓縮等方面進(jìn)行了增強(qiáng)，以滿足TSN網(wǎng)絡(luò)對(duì)于5G設(shè)備的嚴(yán)苛要求。首先從垂直行業(yè)需求入手，分析了5G網(wǎng)絡(luò)與TSN融合的必要性，最后結(jié)合3GPP R16標(biāo)準(zhǔn)進(jìn)展研究了TSN對(duì)于5G商用網(wǎng)絡(luò)改造需求以及面臨的挑戰(zhàn)。

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.
