PURPOSE: To attain the satisfactory call even at the time of a very bad cable transmission line by generating a time slot for control through a time division multiplex multiple access TDMA base station with a control station, belonging to respective TDMA base stations with the time slot for the control and standing by a TDMA terminal station in the idle condition.
CONSTITUTION: A TDMA system is composed of plural TDMA base stations 21∼2n provided corresponding to respective carriers, plural TDMA terminal stations 511∼5ni belonging to these respectively connected with a carrier as a medium and a control station 1 to control the TDMA base stations 21∼2n and the TDMA terminal stations 511∼5ni. The control station 1 generates the time slot for the control through the TDMA base stations 21∼2n, stands by the TDMA terminal stations 511∼5ni which belong to respective TDMA base stations 21∼2n and in an idle condition by the time slot for the control, and when an outgoing call or an incoming call occurs, commands the carrier and time slot to be used to the TDMA terminal stations 511∼5ni to generate the outgoing call or the incoming call through the time slot for the control and executes the call connection. Thus, an equalizer is eliminated and a satisfactory call can be obtained.
