Abstract
An apparatus is capable of restoring a clock of a second node in a communication system with a symmetric network construction of a first node that is capable of receiving a Global Positioning System (GPS) signal, and the second node that is not capable of receiving a GPS signal. The method includes identifying synchronization information received from the first node, determining a delay with the first node, generating a clock using the synchronization information and delay, removing a clock phase being out of a reference range in a phase identification interval, dividing the phase identification interval into at least two subdivision intervals, and removing a clock phase being out of a normal operation range of a phase in each subdivision interval.
