TIME SYNCHRONIZATION METHOD AND APPARATUS

Title:

TIME SYNCHRONIZATION METHOD AND APPARATUS

Document Type and Number:

WIPO Patent Application WO/2016/095099

Kind Code:

A1

Abstract:

Disclosed are a time synchronization method and apparatus. The time synchronization method includes: on the basis that boundary devices in the whole network are all boundary clock (BC) devices, a third-party network side boundary device receiving a synchronization message which carries a time synchronization deviation and is sent by an upstream network side boundary device, wherein the time synchronization deviation is a time deviation between the upstream network time domain and the third-party network time domain; and the third-party network side boundary device transparently transmitting the synchronization message which carries the time synchronization deviation to a downstream network side boundary device, so that the downstream network side boundary device performs time synchronization with the upstream network side boundary device according to the time synchronization deviation. The present disclosure can realize multiple time domains in networking, and realize time synchronization in the multiple time domains.
