(d) Overall control
(d-1) Control at Information Guidance Service Activation FIG. 8 is an explanatory diagram of the control sequence of the present invention at the information guidance service activation.
When the owner of the mobile terminal (for example, the mobile terminal 13a) operates the start key STK, the control unit 142 (FIG. 3) of the mobile terminal enables the infrared receiving unit 144 and the number of the exhibit sent as an infrared signal. Is stored in the memory 145. Note that the memory 145 stores Japanese and explanation summary as default values of language and information depth. Next, the control unit 142 instructs the TDMA processing unit 138 to send a call signal (link channel assignment request). As a result, the TDMA processing unit 138 inserts a call signal (link channel allocation request data) into a predetermined time slot of the control channel, and the radio base station 14a (FIG. 2) from the antenna 131 via the modulation unit 137 and the transmission unit 134. ).

When the radio base station 14a receives the call signal (link channel allocation request data), the radio base station 14a determines a predetermined time slot of an available radio channel as a link channel (call channel), and notifies the mobile terminal 13a of the link channel. When the control unit 142 of the mobile terminal 13a receives the link channel (frequency, time slot) via the TDMA processing unit 138, the control unit 142 instructs the synthesizer 135 to output the frequency signal.
Thereafter, synchronization bursts are transmitted and received between the mobile terminal 13a and the radio base station 14a via the link channel to establish mutual synchronization. If synchronization is established, the control unit 142 of the mobile terminal 13a transmits the service number (for example, 1XY) for receiving the voice response device 21 as a dial number to the radio base station 14a via the control channel (control line), Request call setup.

  Upon receiving the service number 1XY, the radio base station 14a notifies the mobile terminal 13a of acceptance of call setting, and transmits the service number to the exchange 15 via the wired line 31 to request call setting. The exchange 15 recognizes that the call is an incoming call to the voice response device with the service number 1XY, searches for an empty line (referred to as the analog line 41a) from the analog lines 41a to 41n, and sets the empty line as a voice line. Then, a call signal is sent to the voice response device 21 via the voice line 41a. When the line unit 62a (FIG. 6) connected to the voice line 41a receives the calling signal, it inquires of the control unit 61 whether or not it can be accepted. If it can be accepted, it returns a response signal to the exchange 15. Thereafter, the exchange 15 notifies the portable terminal 13a that the voice response device 21 has responded via the radio base station 14a through a call channel. As described above, the communication line between the mobile terminal 13a and the voice response device 21 is established separately from the other mobile terminals.

When receiving the response signal, the control unit 142 of the portable terminal 13a controls the MF oscillator 141 to output the exhibit number, language, and information depth stored in the memory 145 as an MF signal. The codec unit 139 converts the MF signal (exhibition number, language, information depth) into digital, and the TDMA processing unit 138 inserts the MF signal (digital) into a predetermined time slot of the speech channel, and modulates the 137 and transmits it. The signal is transmitted from the antenna 131 to the radio base station 14a via the unit 134.
The radio base station 14a returns the MF signal (digital) to an analog signal and transmits it to the line unit 62a of the voice response device 21 via the exchange 15 and the voice line 41a. A PB receiver (MF signal receiver) 75 in the line unit 62 a converts the MF signal into exhibit number, language, and information depth data, and inputs these data to the controller 72. When the CPU 72a of the control unit 72 receives the audio file designation information (exhibit number a, language b, information depth c) via the PB receiving unit 75, the CPU 72a stores it in the memory 72b and stores the audio file in the control unit 61 (FIG. 6). Queries the head address of the audio file indicated by the designation information abc. Then, the head address notified from the control unit 61 is stored in the memory 72b as the current address in correspondence with the audio file designation information abc. Thereafter, the digital audio data is read from the current address at a cycle of 125 μs and input to the DA converter 74. At the same time, the current address is incremented, and audio data reading is continued thereafter.

The DA converter 74 converts the digital audio data into an analog voice signal and sends it to the voice line 41a, and the exchange 15 sends the audio signal to the radio base station 14a. The radio base station 14a converts the audio signal to digital and sends it to the portable terminal 13a through the call channel. The receiving unit 133 of the mobile terminal 13a extracts a signal from the call channel and inputs the signal to the demodulating unit 136. The demodulating unit demodulates the voice data and inputs the audio data to the TDMA processing unit 138. The TDMA processing unit 138 separates the digital audio data of a predetermined time slot of the speech channel and inputs it to the codec 139. The codec 139 converts the digital audio data into an analog audio signal and outputs it from a speaker or an earphone. As described above, the holder of the portable terminal can listen to the explanation of the exhibit by voice.
Thereafter, when listening to the explanation of the exhibit by voice is finished and the disconnect key SPK is operated, the portable terminal 13a sends a disconnect request to the radio base station 14a through the control channel. As a result, the disconnection signal is sequentially sent to the exchange 15 and the voice response device 21 to disconnect the line between the base station and the exchange and between the exchange and the voice response device. In addition, when receiving the disconnection request, the radio base station 14a exchanges predetermined data with the mobile terminal 13a according to the disconnection procedure to disconnect the call channel.
