[0008] The control device section 20 is provided with a power supply circuit section 21. Electric power is supplied from the power supply circuit unit 21 directly to the control device unit 20 and power is supplied to the wireless communication unit 10 via the electronic switch 22. The electronic switch 22 is connected to a control unit 23 including a microprocessor or the like for controlling ON / OFF of the electronic switch 22. The control unit 23 is provided with a key input unit 24 provided with a dial key, a call rejection mode key, an automatic call key, a power switch, and the like (not shown), in addition to the electronic switch 22. ROM (Rea
d Only Memory) 25, an R for storing transfer destination data such as a home telephone number and a voice mail service center calling number.
An AM (Random Access Memory) 26, a speaker 27 for notifying a call, and a display unit 28 for displaying a received message, a transfer message, a telephone number and the like are connected.

FIG. 2 shows the data structure of the RAM 26. In the flag register F26-1, "0" is set in the normal mode, and "1" is set in the call rejection mode. The transfer destination register TD26-2 stores transfer destination data such as a home telephone number and a voice mail service center calling number.

Next, the processing operation in the embodiment having the above configuration will be described with reference to the flowchart of FIG. This processing is started based on the control of the control unit 23 when power is supplied from the power supply circuit unit 21 by operating the power switch of the key input unit 24. At this time, RAM2
6 is initially set to "0". It is also assumed that, by a predetermined key operation on the key input unit 24, transfer destination data such as a home telephone number or a voice mail service center call number is set in the transfer destination register TD26-2 in advance.

First, in step S1, it is determined whether or not the incoming call rejection mode key has been operated. This allows
During the process, it is always monitored whether or not the communication mode has been switched.

If the incoming call rejection mode key is operated, the process proceeds to step S2, and the operation of the incoming call rejection mode key is performed in the incoming call rejection mode with reference to the flag register F26-1 of the RAM 26. It is determined whether or not there is.

If the flag is not "1", that is, if it is "0", the operation of the call rejection mode key is performed in the normal mode, and therefore, it is determined that the switching from the normal mode to the call rejection mode is instructed. In this case, the process proceeds to step S7, where "1" is set in the flag register F, and the communication mode is switched from the normal mode to the incoming call rejection mode.

Subsequently, the process proceeds to step S8, where the ROM 25
And reads its own ID code and transfers it to the frame processing unit 14 of the wireless communication unit 10. Next, proceeding to step S9, the wireless communication unit 10 generates a wireless channel establishment request signal including the ID code, and transmits the signal to the nearby wireless base station from the antenna 11 via the digital modulation / demodulation unit 13 and the transmission / reception unit 12. . Thereby, the wireless channel of the mobile phone is established.

Further, in step S10, the transfer destination data is read from the transfer destination register TD26-2 of the RAM 26 and transferred to the frame processing unit 14 of the wireless communication unit 10 together with the transfer destination registration request code.

Then, in step S11, the wireless communication unit 10 generates a transfer destination registration request signal based on the transfer destination registration request code and the transfer destination data, and processes the transfer destination registration request signal in step S9. Similarly, it transmits to the radio base station.

With this, the radio base station receiving the transfer destination registration request signal transmits the ID code of the mobile phone and the transfer destination data to the home memory station (calling / transferring ) connected to the communication network.
Transmission control device) and stored in the transfer destination telephone number storage unit assigned to the mobile phone in the call management data storage unit of the home memory station.

Therefore, the call received by the portable telephone is connected to the transfer destination registered in the home memory station of the communication line network, and the caller must inform the family or record the message on the answering machine. Alternatively, it is possible to register with the voice mail service center, which eliminates the need for repeated telephone calls and the like and saves trouble.

Following the above, the process proceeds to step S12, where the electronic switch 2 supplying power from the power supply circuit section 21
2 is turned off, the power supply to the wireless communication unit 10 is stopped, and the process returns to step S1. Thereafter, if there is no operation of the incoming call rejection mode key, the process proceeds to step S13 to confirm that the flag register F26-1 is "1", and repeats returning to step S1.

Thus, during the call rejection mode,
The consumption of power by the wireless communication unit 10 is stopped, unnecessary power consumption of the power supply battery is prevented, and the life of the battery can be extended, which is economical.

Thereafter, when the owner of the portable telephone can communicate with the portable telephone, the call rejection mode is released again by operating the call rejection mode key to return to the normal communication mode. it can.

If the operation of the incoming call rejection mode key is determined in step S1, it is confirmed in step S2 that the flag register F26-1 is "1", that is, the call is in the incoming call rejection mode. To step S3.

In step S3, the flag register F26
-1 is set to "0" to switch from the call rejection mode to the normal mode. Thereby, the incoming call rejection mode is released.

Subsequently, in step S4, the electronic switch 2
2 is turned on, and power supply from the power supply circuit unit 21 to the wireless communication unit 10 is restarted. Next, in step S5, the wireless communication unit 10 generates a wireless channel establishment request signal including the ID code again and transmits the generated signal to the wireless base station. Thereby, the wireless channel of the mobile phone is established again.

Next, in step S6, the erasure request code of the transfer destination registration is transmitted to the frame processing unit 14 of the radio communication unit 10.
The wireless communication unit 10 generates a transfer destination registration deletion request signal based on the deletion request code, and sends the transfer destination registration deletion request signal to the wireless base station.

As a result, the data stored in the transfer destination telephone number storage unit assigned to the portable telephone in the paging management data storage unit of the home memory station of the communication line network registered via the radio base station is erased. You. Therefore, after that, normal wireless communication by the mobile phone can be resumed for both transmission and reception.

As described above, the incoming call rejection mode is canceled, and if it is determined in step S13 that the flag register F26-1 is "0", the process proceeds to step S14.
To perform the normal processing.

In this normal processing, processing such as reception of a call signal from the caller to the owner and a telephone call, and call from the owner to an arbitrary party and a telephone call are performed. Further, an automatic calling process is also performed by an automatic calling key. With this, RAM
26, it is possible to automatically call the transfer destination by the transfer destination data stored in the transfer destination register TD26-2, and therefore, it is possible to easily check the telephone call received during the call rejection mode time. Can be.

In the above-described embodiment, the power supply to the radio communication unit 10 is stopped in the incoming call rejection mode, and it is not known whether there is a call during the incoming call rejection mode. Another embodiment will be described below.

FIG. 4 is a circuit diagram of a portable telephone according to another embodiment. The components having the same functions as those of the first embodiment are given the same numbers as those of the first embodiment.

In FIG. 1, the portable telephone 2 includes a radio communication unit 10 and a control unit 30, and power is supplied from a power supply circuit (not shown). The wireless communication unit 10
Antenna 11, transmission / reception unit 12, digital modulation / demodulation unit 13, frame processing unit 1 having the same functions as in the first embodiment
4. Voice codec unit 15, receiver 16, and transmitter 1
Consists of seven.

The control unit 30 is provided with a control unit 23 'for controlling the frame processing unit 14 of the radio communication unit 10. The control unit 23 'includes a key input unit 24' provided with a dial key (not shown), a ringing sound prohibition key, an automatic call key, a power switch, etc., a home telephone number, a voice mail service center call number, and the like. In addition to a RAM 26 'for storing the transfer destination data and the number of transfers, a ROM 25 having the same functions as in the first embodiment, a speaker 27, and a display unit 28 are connected.

FIG. 5 shows the internal configuration of the RAM 26 '. The flag register M26'-1 is set to "0" in the normal communication mode and "1" in the ringing tone generation prohibition mode. Count data register 26 '
"-2" stores the number of times of call transfer in the ring tone generation prohibition mode. Also, the transfer destination data register 26'-2
Stores transfer destination data such as a home telephone number and a voice mail service center call number.

Next, the processing operation in the second embodiment having the above configuration will be described with reference to the flowchart of FIG. This process is started when power is supplied from the power supply circuit by operating the power switch of the key input unit 24 '. This process is performed based on the control of the control unit 23 '. The destination data such as a home telephone number or a voice mail service center calling number is previously set in the destination data register 26'-2 of the RAM 26 'by a predetermined key operation on the key input unit 24'. It is assumed that the flag register M26'-1 and the count data register 26'-2 are each initialized to "0" upon power-on.

First, in step S61, it is determined whether or not the ringing inhibition key has been operated. Thus, during the processing, the operation of the ringing inhibition key is always monitored. If the ringing prohibition key has been operated, step S6
2 to the flag register F26'-1 of the RAM 26 '.
, It is determined whether or not the operation of the above-mentioned ringing inhibition key is performed in the normal mode.

If the flag of the flag register F26'-1 is "0", the operation of the ringing inhibition key is performed in the normal mode, and therefore, it is instructed to switch from the normal mode to the silent mode. In this case, the flow proceeds to step S63 to set "1" in the flag register F, switch the communication mode from the normal mode to the silent mode, and further turn off the sound drive circuit of the speaker 27 to stop the sound function. Then, the process returns to step S61.

On the other hand, if the flag of the flag register F26'-1 is "1" in step S62, the operation of the ringing inhibition key is performed in the silent mode.
Therefore, it is determined that switching from the silent mode to the normal mode has been instructed. In this case, the process proceeds to step S64, where "0" is set in the flag register F, and the communication mode is switched from the silent mode to the normal mode. Speaker 2
Turn on the sound drive circuit 7 and restore the sound function.
It returns to step S61.

With this operation, the communication mode is alternately switched between the normal mode and the silent mode each time the ring tone generation prohibition key provided on the key input section 24 'is operated. In the silent mode, the call to the portable telephone is made. Even if there is no ringing sound.

If it is determined in step S61 that the ringing tone generation prohibition key has not been operated, the flow shifts to step S65 to determine whether there is a wireless call. In this determination, if there is no wireless call, the process immediately returns to step S61. If there is a wireless call, the flow proceeds to step S66 to refer to the flag of the flag register F26'-1 and determine whether the current communication mode is the normal mode or the silent mode. Is determined.

At step S66, the flag register F
If the flag of 26'-1 is "1", that is, it is in the silent mode, in step S67, its own ID is read from the ROM 25.
The code is read and transferred to the frame processing unit 14 of the wireless communication unit 10.

Subsequently, the flow proceeds to step S68, where the radio communication unit 10 generates a radio channel establishment request signal including the ID code, and transmits it from the antenna 11 to the radio base station via the digital modulation / demodulation unit 13 and the transmission / reception unit 12. I do. Thereby, the wireless channel of the mobile phone is established.

Next, in step S69, the transfer destination data is read out from the transfer destination data register 26'-2 of the RAM 26 'and transferred to the frame processing unit 14 of the radio communication unit 10 together with the transfer request code.

In step S70, the wireless communication unit 10 generates a transfer request signal based on the transfer request code and the transfer destination data, and sends the transfer request signal to the wireless base station.

As a result, the ID code of the mobile phone and the transfer destination data are transmitted to the home memory station or the call control station connected to the communication network by the radio base station which has received the transfer request signal, and is transmitted to the mobile phone. The call is connected to the transfer destination, and the caller can convey the matter to the family member, record it on the answering machine, or register with the voice mail service center, and need to make repeated calls, etc. Is eliminated and the trouble is saved.

Following the above, the process proceeds to step S71, where R
The count data register 26'-2 of the AM 26 'is incremented by "1", and the process returns to step S61. Thereafter, if there is no operation of the ringing inhibition key, the flag register F is set at step S66 each time a wireless call is made to the mobile phone.
After confirming that 26-1 is "1", steps S67 to S71 and S61 are repeated.

Thus, during the silent mode period, the number of times the incoming call has been transferred to the transfer destination is stored in the RAM 26 'and displayed on the display unit 28. If it is determined in step S66 that the flag register F26-1 is "0", it is determined that the mode is the normal mode, and normal processing is performed in step S72.

In this normal processing, normal transmission and reception are performed in the same manner as in the first embodiment, and an automatic call processing is also performed using an automatic call key. In this case, the transfer count stored in the count register 26'-2 of the RAM 26 'is displayed on the display unit 28.
, The automatic call key may be operated after confirming the display. When the automatic call key is operated, RAM2
A call is automatically made to the transfer destination according to the transfer destination data stored in the transfer destination data register 26'-2 of 6 '. Since the number of transfers is stored in the number register 26'-2, the automatic calling process can be automatically performed when the silent mode is switched from the silent mode to the normal mode.

Thus, the owner can easily refer to the number of transfers displayed on the display unit 28 and confirm all the telephone calls made a plurality of times during the silent mode time.

As described above, in the second embodiment, the number of calls is stored for the call during the silent mode, so that the operation of confirming the message stored or transmitted at the transfer destination can be efficiently performed. Can be done.

In the first embodiment, the normal mode and the incoming call rejection mode are alternately switched by the incoming call rejection mode key. In the second embodiment, the normal mode and the silent mode are switched by the ringing sound generation prohibition key. Although the switching is performed alternately, the present invention is not limited to such a mode switching method. In any case, the switching may be performed by providing a dedicated key corresponding to each of the normal mode and the other modes.

Although the number of transfers is stored in the second embodiment, a configuration may be used in which only the transfer, that is, the fact that there is a call is stored.

[0052]

As described above, according to the present invention, transfer data for transfer to a telephone at home or a voice mail service center is stored in a communication terminal device, and the transfer data is stored based on a predetermined instruction. Since the transfer destination data is transmitted to the call / transfer control device, the transfer destination data can be easily registered in the call / transfer control device. Furthermore, after transmitting the transfer data,
Power supply can be stopped, reducing power consumption
I can do it. If the call notification is not set, the transfer destination data stored for each call is transmitted to the call / transfer control device. Therefore, the transfer destination data can be easily transmitted to the call / transfer control device. You can register. Note that, in this case, the call / transfer control device does not need an operation to cancel the transfer setting by transferring only the call that has received the transfer destination data. Further, since the configuration is such that a call is made or the number of transfers is stored and the fact is notified, the transfer destination is automatically called by a predetermined key operation later, so that the communication terminal device can receive the contents of the transfer destination. Can be confirmed.
