Patent ID: 7649871

Claim:
A communication control apparatus mounted on a network node constituting a telecommunications system, comprising: a node type information transmitter/receiver for receiving node type information selected by a neighboring node, and transmitting node type information selected by the network node and node type information of another node; a state variable signal transmitter/receiver for receiving a state variable signal of the neighboring node reflecting a phase representative of a timing of data transmission from the neighboring node, and transmitting a state variable signal representative of a timing of data transmission from the network node; a node type selector for selecting a node type of the network node in accordance with node type information of the other node received via said node type information transmitter/receiver; and a transmission timing calculator operative in response to the node type information of the network node selected by said node type selector, the node type information of the other node and the state variable signal of the neighboring node for varying a state of the phase of the network node in accordance with a time evolution rule based on a phase response function and a synchronization alliance function for thereby determining a data transmission timing of the network node, the time evolution rule changing a nonlinear oscillation rhythm of the phase of the network node in response to an impulse signal received from the neighboring node.
