Abstract: 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.

Key words: the 5th generation of mobile communications system, time sensitive networking, time synchronization, delay measurement; resident time
