TIME SYNCHRONIZING METHOD, DEVICE AND SYSTEM OF MASTER CLOCK SIDE AND SLAVE CLOCK SIDE IN SYNCHRONOUS NETWORK

摘要

In the field of communications, a method, device, and system for synchronizing time of a master clock side and a slave clock side in a synchronous network are provided, which are designed to solve a technical problem of time synchronization in the synchronous network. The method for synchronizing time of a slave clock side in a synchronous network includes the following steps. A synchronization message borne in a first downlink frame is received. An entry indicating pulse is generated according to the received first downlink frame, in which a time delay between the entry indicating pulse and a framing byte in the first downlink frame is fixed. First time of the slave clock side is collected according to the entry indicating pulse. A follow-up message borne in a second downlink frame is received, in which the follow-up message carries first time when a master clock side sends the synchronization message. Local time is adjusted according to a difference between the first time of the master clock side and the first time of the slave clock side.
