摘要： Methods and related systems for synchronizing a communication node in a communication network are provided. The methods generally involve the request and transmission of the local clock of a neighboring communication node for use at the communication node instead of using the clock information of the external clock source, at least for a predetermined amount of time. By using the clock of a neighboring communication node, a communication node which local clock cannot be based on an external source, because it is unavailable or has become corrupted, can remain synchronized with the other communication nodes in the communication network.
