という欠点があった。Conventionally, in order to send data efficiently, the conventional communication system used a round-robin scheduling system in which the transmission channel was selected based on the average value of each channel. Ta. however,
In this method, once a channel is selected, there is no choice but to wait until that channel becomes vacant (there was a drawback in that it was impossible to keep the transmission waiting time to a fixed amount of time due to the traffic on that channel).
本発明の目的は、前記した欠点を改良し、送信待時間を

に移る。Senou-geki # section 6 scans the transmission 1-waiting key row 8&~・at fixed intervals corresponding to each channel.
It is determined whether or not there is a transmission event in the i-trust center, and the transmission control unit 6Kal commands the transmission right. At this time, the queue control s6 grasps the waiting time of the overconfident event in each of the transmission waiting key columns 61 to 81 from the above scan interval, and determines the waiting time of the overconfident event in each of the transmission waiting key columns 61 to 81, and determines the waiting time of the overconfidence event (transmission event) tj1 which has been waiting for more than -m hours.
Shinmaki Ki Tame is in time act from part 8--II (FIF
O control) Move to 7. At the same time, it instructs the transmission control unit 6 to perform overconfidence mail for all channels other than those currently being transmitted from its own terminal. When the transmission right is sequentially acquired in the transmission control 116, the kill control 1116 sequentially extracts transmission events from the timeout key 1117 and moves to the transmission operation.

While the timeout tool-s7 is performing the transmission JI&ll, the key controller 6 performs periodic scanning and only detects timeout events.

ある。If the data to be transmitted remains in the queue of keys waiting to be transmitted even after a certain period of time, a method is adopted in which the data is transmitted using another channel. For this reason, the probability of acquiring the transmission right increases, and a) when the channel is overloaded, the transmission waiting time increases rapidly.In the C8MA/CD system, data can be transmitted with an average transmission waiting time. effective.

にしたことを％鎗とする通信制御方式(1) Communication using a coaxial cable, using a wideband method that transmits and receives multiple signals simultaneously in a superimposed manner using a wideband (modulation) method, and using a network operation method called COMA/CD within each band @ (channel). In the control method, transmission data is keyed for each channel by a queue selector control unit and a knee selector control unit. The timeout part, where the transmitted data is transferred,
It is also equipped with a key control unit that checks the presence or absence of some transmission data, checks the waiting time of data waiting to be transmitted, and acquires transmission rights including other channels. If the samurai key is in one part, the key control unit moves the transmission data to the Aiki timeout key part and performs the operation to acquire the transmission right including other channels, so that the transmission right can be acquired as soon as possible. A communication control method that uses a channel to transmit data in a part of the timeout queue.
