Study on network architecture evolution and enhancement technology for 5G TSN

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.
