摘要
为了深入研究第5代移动通信系统(5G)和时间敏感网络(TSN)融合网络中的TSN时间同步,基于模块化对象的C++语言网络测试平台设计并开发了TSN转换器网元进行仿真实验。提出了一种基于5G驻留时间补偿的时延测量方法,以解决5G路径传输时延的测量值与实际值存在较大偏差的问题。仿真实验结果表明,若5G和TSN具备相同且较高的时间同步精度,在融合网络中采用改进的时延测量方法能够实现微秒级的TSN时间同步。
In order to study the time synchronization of time sensitive networking(TSN)in 5th generation mobile communication(5G)and TSN converged network deeply,TSN translating network elements are designed and developed based on the OMNeT++platform,and simulation experiments are carried out.A delay measurement method based on compensation of 5G system resident time is proposed to solve the problem that the measured value of the transmission delay of 5G system has a large deviation from the actual value.The simulation results show that if the 5G system and the TSN system have the same and high time synchronization accuracy,the improved delay measurement method enables microsecond level time synchronization of TSN in the converged network.
