In addition, the signal is transmitted through the modulator 114, the transmission unit 115, the antenna switching unit 130, and the transmission / reception antenna 131.

[0007]

However, in the conventional mobile radio apparatus, the transmission data input from the microphone 111 cannot be taken into the control unit 120, and the control unit 120 is not available.
There is a problem that the data stored in the RAM 122 or the ROM 123 cannot be output as voice from the receiver 101.

Therefore, according to the present invention, by storing the transmission data, the transmission data stored in the control unit 120 can be combined with the reception data and reproduced by the receiver 101, and the transmission data input from the microphone 111 can be reproduced. It is an object of the present invention to provide a mobile wireless device that can be stored in a mobile phone.

SUMMARY OF THE INVENTION In a digital mobile radio apparatus for performing communication using a digital radio line, accumulating and processing received data, and transmitting pre-stored control data in addition to transmission data, the accumulated data is stored. There are provided means for reproducing the received data, means for reproducing the control data in addition to the accumulated received data, means for accumulating and processing the transmitted data, and means for transmitting the accumulated transmitted data.

[0010]

In the mobile radio apparatus of the present invention, in addition to the function of transmitting the control data stored in advance in addition to the transmission data,
Since the stored received data is played back, the control data is played back in addition to the stored received data, and the sending data can be stored, processed, and transmitted, the answering function and the message recording function can be performed only by the mobile wireless device. It can be applied as an answering machine.
