Abstract:
1. A communication control apparatus installed in a communication node in a telecommunications system, the telecommunications system being formed by a plurality of communication nodes including a first node group of bypass nodes disposed in a first area and having a high quantitative request to relay data, and a second node group of non-bypass nodes disposed in second areas surrounding the first area and having a lower quantitative request to relay data than the first node group, said apparatus comprising: a signal receiver for receiving a first state variable signal from a neighboring node of the plurality of communication nodes which is in a vicinity of the communication node in which said apparatus is installed, the first state variable signal indicating a timing of data transmission from the neighboring node; a calculator for varying a plurality of phase signals different in oscillation period in response to the first state variable signal received from the neighboring node, synchronizing states of the phase signals so that the phase signals interact with each other, and temporally multiplexing, within an oscillation period of one of the phase signals, a plurality of data transmission periods different in time slot width and representing a transmission time period between the communication node in which said apparatus is installed and the neighboring node based on oscillation periods of the phase signals to thereby form a communication timing; and a signal transmitter for transmitting a second state variable signal defining a timing of data transmission from the communication node in which said apparatus is installed based on one of the phase states of the phase signals caused to interact with each other by said calculator; said calculator comprising a state manager for managing states of phase signals for the communication node in which said apparatus is installed and the neighboring node different in oscillation period, and for prescribing an order relationship of time-slot allocation.
