Title:
SYNCHRONIZATION METHOD, SYNCHRONIZATION DEVICE, SYNCHRONIZATION APPARATUS AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/099375
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present disclosure are a synchronization method, a synchronization device, a synchronization apparatus and a system. The method applied in a first device comprises: synchronizing the first device with N second devices adjacent to the first device to obtain a time signal of a master time of each of the second devices, N being an integer not less than 2; locking and tracking said N time signals, to form N slave times; and calibrating, according to the N slave times, the master time of the first device. First, after the time signals of the second devices are obtained, the time signals will be locked and tracked to form slave times, thus avoiding the problem that synchronization cannot be achieved when acquiring time signals repeatedly or multiple times or the synchronization effects are poor. Second, the first device obtains the time signals of a plurality of adjacent second devices to synchronize with, rather than to be synchronized with an upstream device, thereby reducing the accumulation of synchronization errors caused by the synchronization of the downstream device and the upstream device, improving synchronization accuracy.
