ABSTRACT:
The present invention relates to a communication method using a small-scale computer network and a communication equipment used therefor. Particularly, a novel communication method in a communication equipment is capable of accumulating a plurality of communication data, i.e., frames at the same time and having a function to sequentially transmit them to the network. According to this method, after transmission of a single frame is completed, when the condition is satisfied that a predetermined time has passed or the condition that the transmission of the frame from any other communication equipment is completed, transmission of the next frame is initiated. Accordingly, this method eliminates the possibility that solely a specified communication station occupies the network, thus making it possible to improve efficiency in use of the network.
