CROSS DOMAIN SYNCHRONIZATION IN A COMMUNICATION NETWORK

Title:

CROSS DOMAIN SYNCHRONIZATION IN A COMMUNICATION NETWORK

Document Type and Number:

WIPO Patent Application WO/2019/024079

Kind Code:

A1

Abstract:

A method for communications is proposed. The method may comprise receiving, by a first network node, a report of clock quality of a second network node from a third network node. A clock of the first network node is selected as a master clock for synchronization in a first timing domain, a clock of the second network node is selected as a master clock for synchronization in a second timing domain, and the third network node is attached to at least the first timing domain and the second timing domain. Based at least in part on the received report, it may be determined whether to synchronize the first timing domain to the second timing domain. In response to the determination of synchronizing the first timing domain to the second timing domain, the first network node can obtain timing information of the second network node from the third network node. The method may further comprise tuning the clock of the first network node to synchronize the first timing domain to the second timing domain, based at least in part on the timing information of the second network node.
