PURPOSE: To provide mobile object communication decreasing the transmitting/ receiving information quantity of telephone signals.

CONSTITUTION: This method uses respective radio base stations 30 to cover plural zones and a gate exchange 20 for exchanging communication with respective mobile radio equipments 100 by using a radio channel loading the telephone signal for communication with the radio base stations 30. Both of the radio base stations 30 and the mobile radio equipments 100 store a lot of time piece signals which the telephone signal is fractionized in time at the beginning stage of speaking, and during speaking, only the identification signal of the time piece signal is transmitted and corresponding to this identification signal, the telephone signal is reproduced at the reception side. Thus, the quantity of information to be transmitted is drastically decreased. Further, this method can be also used for reducing the electric power of transmission.
