Abstract

PURPOSE:To prevent effectively the reduction of the transmission velocity by letting the system control station know the transmission request and at the same time designating the corresponding station to the transmission and reception modes based on the received transmission and reception addresses for carrying out the data transmission between the stations. CONSTITUTION:The specified one of stations ST1, ST2 ... STj is selected as system control station SC. Then the control command ordering detection of the transmission request is transmitted to each station via station SC. And at the station where the signals are received, the repeating of the control command to the downstream stations is inhibited in case the transmission request is given. At the same time, the transmission and reception end addresses having the transmission request are sent back to station SC after detection of completion for reception of the control command. As a result, station SC can know the transmission request and also designates the corresponding station to the transmission and reception mode based on the received transmission and reception addresses. Thus, the reduction of the transmission velocity can be prevented effectively.
