Time synchronization method and system in Mobile time-sensitive network

摘要

A time synchronization method in a mobile TSN according to an embodiment of the present invention comprises: calculating, by a controller, a clock offset difference value of network configuration nodes between communication links before and after changing an AP communicating with a communication terminal; transmitting, by the controller, an offset difference value correction message including the clock offset difference value to the new AP; transmitting, by the new AP, the offset difference value correction message and the local synchronization message to the communication terminal requiring time synchronization; performing, by the communication terminal, synchronization of a local clock when the local synchronization message is reliable; performing time synchronization by reflecting a clock offset difference value when the local synchronization message is unreliable; includes
