Patent ID: 7466685

Claim:
Communication control apparatus to be included in a communication node forming a telecommunications network, comprising a transmission timing calculator responsive to a state of a phase changing in an own node for determining a first timing at which the own node transmits data, wherein said transmission timing calculator comprises: a phase calculator operative in response to receiving a state variable signal, transmitted by a neighboring node and affected by a phase representative of a second timing at which the neighboring node transmits data, for changing a state of a phase of the own node in accordance with a time development rule; a collision ratio calculator for monitoring a phase difference of the own node with respect to the neighboring node, and operative in response to the phase difference for calculating a ratio of collision on the first and second timings; and a stress response function value generator for storing time-serially a stress value corresponding to the ratio of collision, and operative in response to the stored stress value for causing the time development rule to provide a phase shift with a value of the phase shift made at random and wherein the time development rule defines a phase response function having a dynamic characteristic changing, when a relative phase difference between the own and neighboring nodes does not exceed a phase width required for avoiding collision, the phase of the own node with respect to the phase of the neighboring node in a direction effecting a repulsion force.
