TIME SYNCHRONIZATION METHOD, FIRST NODE, SECOND NODE, AND NETWORK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18032837 titled 'TIME SYNCHRONIZATION METHOD, FIRST NODE, SECOND NODE, AND NETWORK

Simplified Explanation

The present disclosure describes a time synchronization method for communication systems.

  • The method is applied to a first node that is connected to a second node via an out-of-band synchronization link and to a third node via an in-band synchronization link.
  • The first node sends out-of-band time synchronization information to the second node, which includes the identity of the grandmaster clock of the first node.
  • This method ensures accurate time synchronization between the first and second nodes.
  • The disclosure also provides a time synchronization method for the second node, as well as for the first and third nodes.
  • The disclosed methods improve the overall time synchronization accuracy in a network.


Original Abstract Submitted

Embodiments of the present disclosure relate to the technical field of communications, and provide a time synchronization method applied to a first node provided with at least one output port connected to an input port of a second node via an out-of-band synchronization link and at least one additional output port connected to a third node via an in-band synchronization link, and the method includes: sending out-of-band time synchronization information to the second node via the out-of-band synchronization link, with the out-of-band time synchronization information including a grandmaster clock identity of the first node. The embodiments of the present disclosure further provide a time synchronization method applied to a second node, a first node, a second node, and a network.
