Abstract: Provided are a method of synchronizing a communication network, the method comprising obtaining a quality parameter of at least two or more synchronization sources connected to communication nodes in a communication network and a capacity parameter of the communication nodes connected to the synchronization sources, selecting a synchronization source to be used for synchronization of the communication network from among the at least two or more synchronization sources, according to a priority based on the obtained quality parameter and capacity parameter and performing synchronization of the communication network using a synchronization signal provided from the selected synchronization source.

Abstract: Provided are a clock synchronization method performed between communication nodes included in a communication network, the clock synchronization method comprises receiving a synchronization source signal through any one of remaining communication nodes except for an uppermost communication node included in the communication network, generating a reference clock for clock synchronization from the received synchronization source signal and transmitting the generated reference clock through a first path including at least a portion reverse to a second path through which a downlink signal is transmitted in the communication network.

Abstract: A synchronization method of a communication network, the synchronization method comprises monitoring a connection state of second communication nodes that are synchronized using a synchronization signal provided through a first communication node to which a synchronization source is connected, determining whether the number of the connected second communication nodes exceeds a reference value according to a result of the monitoring and switching a synchronization mode of at least one second communication node when the number of the second communication nodes exceeds a reference value.

Abstract: A communication system comprises a clock generator configured to generate a plurality of system clock signals used to synchronize components included in each of communication nodes in the communication system based on an external clock signal provided by an external clock source located outside the communication system and a physical layer configured to transmit any one of the generated system clock signals to a small cell communicatively connected to an end communication node of the communication system.
