Abstract
The present disclosure provides a method and time synchronization node for enabling extended holdover time. The method comprises: detecting whether the TS node loses time synchronization with its master TS node or not; and transmitting a first announce message comprising a first indicator to one or more slave TS nodes in response to detecting that the TS node loses the time synchronization with its master TS node, wherein the first indicator indicates a holdover time budget for enabling extended holdover time at the one or more slave TS nodes.
