Communication control apparatus for determining data transmission timing with node type and a state variable
First Claim
1. 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.

Abstract
A communication control apparatus, mounted on each node of a telecommunications system, receives node type information selected by a neighboring node, and transmits node type information selected by the own node and node type information of another node. The apparatus receives the state variable signal of the neighboring node reflecting a phase representing another node'"'"'s data transmission timing, and transmits a state variable signal representing the own node'"'"'s data transmission timing. Subsequently, the apparatus selects the own node'"'"'s node type in accordance with another node'"'"'s type information received. The apparatus then varies, based on the own node'"'"'s node type information selected, another node'"'"'s node type information and the neighboring node'"'"'s state variable signal, the state of the own node'"'"'s phase in accordance with a time evolution rule based on a phase response function and a synchronization alliance function for thereby determining the own node'"'"'s data transmission timing.
