Abstract

PURPOSE:To attain efficient communication in a short waiting time with a master station by setting a communication start timing at every slave station at disabled communication and allowing a slave station to start the communication in the earliest set timing in case of enabled state. CONSTITUTION:Mobile stations 3, 4 withdraw transmission during the transmission by a mobile station 2. When the transmission of the station 2 is finished at a time t14, the stations 3, 4 generate random numbers 2, 3 respectively and only times W2, W3 multiplying the unit time W1 have no communication. The station 3 at a time t15 discriminates whether or not the other stations 2, 4 make transmission and in case of transmission enable, the transmission is applied. On the other hand, the station 4 discriminates again whether the transmission is enabled or not at a time t16 lapsing the time W3. Since the station 3 makes transmission at this time, the transmission is withdrawn. When the transmission of the station 3 is finished at a time t17, since communication is enabled, the station 4 generates again a random number 1 and whether or not the transmission enable is attained by a time t18 elapsed by the time W4 corresponding thereto and the transmission is started at communication enable.
