PURPOSE:To enable communicating data while executing a call by means of a single radio telephone system by assigning plural TDMA slots to the call and data communication. CONSTITUTION:When a calling operation is executed from a slave set through the use of an operating part 12, a central control part 111 decides a frequency and slot to be used by a previously decided means and sets the frequency and transmission electric power in a radio control part 110. The setting of the applying slot is executed in a slot change-over part 106 and a voice pass is controlled by a voice processing part 107. Then, the control part 111 transmits a calling request command to a master set from the change-over part 106, the change-over part 106 puts data on the designated slot and the calling request command is transmitted from a transmitting part 105 to the master set. When a personal computer, etc., executes the calling operation through a data communication interface part 114, the control part 111 sets the applying slot to the change-over part 106 in the same way, puts data on the designated slot and transmits the calling request command to the master set. |
