PURPOSE:To provide a mobile object communication system where the electric power of signals are compared with each other between an adjacent frame where the time compression is applied to a time slot of a frame constitution and a frame adjacent to the succeeding adjacent frame and a time one-way telephone signal is not put on the time slot when the difference of electric power between both signals is less than the fixed value. CONSTITUTION:Each radio basic station 30 covers plural zones. A barrier switchboard 20 uses a radio channel where the time one-way signal suppressed down to a level that is compressed and divided in terms of time put on a time slot of a frame constitution for the communication with the station 30 and then switches the communication among the mobile radio equipments 100. Then the electric power of the time one-way telephone signals are compared with each other between an adjacent frame and the succeeding adjacent frame. If the difference of the electric power between both signals is less than the fixed value, no time one-way telephone signal is put on the time slot. Thus the large multilex load gain is acquired. Then the transmission power is reduced and the frequency can be effectively used. |
