Patent ID: 7864811

Claim:
A telecommunications control device mountable on a network node constituting a telecommunications system together with a neighboring node, comprising: a timing control signal receiver for receiving a timing control signal transmitted from the neighboring node with a first phase indicative of data transmission timing of the neighboring node reflected; a transmission timing calculator for varying a phase state of the network node, based on the timing of reception of the timing control signal of the neighboring node, to determine data transmission timing of the network node; a timing control signal transmitter for transmitting a timing control signal in which a second phase indicative of data transmission timing of the network node is reflected, said second phase being determined by said transmission timing calculator; a data communicator for transmitting, and receiving a data signal to and from the neighboring node; and a phase state manager for controlling transmission of the timing control signal and the data signal in accordance with the phase state of the network node, wherein said phase state manager, upon determining the phase state of the network node to be in a convergence state, reduces a time interval during which the timing control signal is transmitted, and transmits the data signal as a substitute for the timing control signal, and said data communicator, under control of said phase state manager, merges information indicative of the substitute for the timing control signal into the data signal and transmits the merged signal.
