Accordingly, the baseband circuit 220 causes the base station demodulated signal to be subjected to reception baseband processing, and outputs the base station baseband signal to the baseband circuit 250.

Then, the baseband circuit 250 causes the base station baseband signal to undergo transmission baseband processing and output a base station speech signal. Along with this, the base station communication signal is modulated by the high frequency modulation / demodulation circuit 240 to output the vehicle interior communication signal. For this reason, the vehicle interior communication signal (receiving signal) is transmitted from the antenna 230 to the in-vehicle hands-free device A.

That is, when a vehicle interior call signal is received from the mobile phone B by the antenna 10, at step 604,
The high-frequency modulation / demodulation circuit 20 demodulates the vehicle interior communication signal and outputs the vehicle interior demodulated signal. Accordingly, the baseband circuit 30 performs the reception baseband processing on the demodulated signal in the vehicle compartment, and outputs the received baseband signal in the vehicle compartment.

Further, the digital-to-analog converter 50 performs digital-to-analog conversion of the in-vehicle reception baseband signal to output an analog signal. For this reason,
The speaker 60 outputs a received voice based on the analog signal.

Further, the analog-digital converter 80
When receiving the transmission signal from the microphone 70, the transmission signal is converted from analog to digital and a digital signal is output.
Along with this, the digital signal is subjected to transmission baseband processing by the baseband circuit 30 to generate a vehicle interior transmission baseband signal.

Further, the high frequency modulation / demodulation circuit 20
The transmission baseband signal in the vehicle interior is modulated, and the modulated signal in the vehicle interior is output to the antenna 10 (step 605).

If it is determined that the abbreviated number has been input, the abbreviated number is output to the baseband circuit 30. Accordingly, the baseband circuit 30 outputs the shortened number to the antenna 10 through the high frequency modulation / demodulation circuit 20. Therefore, the abbreviated number is transmitted from the antenna 10 to the mobile phone B.
Thereafter, the same processing as in steps 604 to 607 shown in FIG. 4 is performed.

Next, transmission processing of the portable hands-free program in the control circuit of the portable telephone B will be described.

That is, a request signal is output to baseband circuit 210 in order to request the base station to connect to the telephone number. Accordingly, the baseband circuit 2
10 causes the request signal to be output to the antenna 200 through the high-frequency modulation / demodulation circuit 210. Therefore, the request signal is transmitted from the antenna 210 to the base station. afterwards,
The same processing as in steps 502 to 506 shown in FIG. 4 is performed.

By the way, since the portable hands-free program is different for each model of portable telephone, it is necessary for the portable telephone B to carry the portable hands-free program corresponding to the model when making a hands-free call. . Hereinafter, a process for causing the mobile phone B to download the mobile hands-free program corresponding to the model will be described.

Each of the received portable hands-free programs is output to the control circuit 40 via the baseband circuit 30 via the high-frequency modulation / demodulation circuit 20. Thereby, the control circuit 40 can store the portable hands-free program (and the in-vehicle hands-free program) in the ROM 110.

Next, the processing performed by the hands-free device A and the mobile phone B when the mobile phone B is brought into the vehicle will be described with reference to FIGS.
