DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone set, and more particularly to a telephone set which can easily or automatically call a specific destination telephone number in order to use a pager service and a nuisance call refusal service.

[0002]

2. Description of the Related Art Some telephone services, such as a pager service and a nuisance call refusal service, require a call to a specific telephone number. In the call-only pager service, for example, when a certain person goes out of the office, a pager is carried. When a person in the company wants to contact a person outside the office, he dials a predetermined contract telephone number associated with the pager. Then
The center sends a calling signal and rings the pager, and the caller receives an announcement via the line saying "I am calling the pager. Please hang up and wait." Outsiders can hear that the company is calling themselves by ringing a pager, and then call the nearest public telephone to listen to their business. In addition, with the display pager service, dial the contract phone number and from the center, "This is XX
○○ Press the number you want to convey. Is returned, press a message number such as a telephone number or an abbreviation (for example, if the telephone number to be communicated is 34-1234).
When * 2 represents a hyphen and # is used as an end symbol, it is pressed as 34 * 21234 #. ), The center transmits the message number together with the calling radio wave, rings the pager, and displays the message number on the display. Therefore,
The carrier can also know the content of the message from the caller.

On the other hand, in the nuisance call refusal service, when a prank call arrives at a certain person, the call is temporarily cut off, and a telephone number (for example, 144) for the nuisance call rejection service is dialed. Then, a signal sounding "Puppu ..." is returned from the exchange of the office, and the number (for example, 2) indicating that the refusal service is turned on is pressed. At this time, the exchange of the office stores the telephone number of the person who made the prank call in the call rejection memory, and then, when the same caller calls the certain person, the telephone is not connected. ,
Announce to the caller that "Cannot connect due to circumstances".

[0004]

However, in order to use the pager service and the nuisance call refusal service, it is necessary to answer a call to an outsider and still be on a call, or to answer a mischievous phone call. During a call, or when the call has ended but is off-hook, place the handset once, lift it again, or press the hook switch to release it again, disconnect the line once, then go off-hook again After confirming that the line was closed from the dial tone, the user had to dial the contracted telephone number for pager calling or the telephone number 144 for the nuisance call refusal service, and the operation was troublesome. . Also, even if you use the pager service or the nuisance call rejection service while waiting for a call in the on-hook state, after picking up the handset and closing the line, use the contracted telephone number for pager calling or the nuisance call rejection service Have to dial the phone number of
Operation was troublesome. If you want to use the display pager service, you need to dial the message number after dialing the contract phone number. If you want to use the nuisance call refusal service, dial 2 after 144 to indicate that the refusal service is on. It is necessary, and the operation is very troublesome for those who are not familiar with the operation.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem of the prior art, and it is possible to completely automatically make a call to a predetermined telephone number for a nuisance call rejection service when a mischievous call is received.

It has a registration button, a second registration button, an automatic call button, and the like. Reference numeral 21 denotes a control microcomputer which performs registration of a telephone number and transmission information for a predetermined automatic call in addition to normal call control,
A predetermined automatic transmission control is performed in response to an automatic transmission instruction operation in a standby state, and a predetermined automatic transmission control is performed when a silent state is maintained for a predetermined time during an incoming call. When a telephone number is dialed by a dial button of the key matrix 20, the control microcomputer 21 controls the hook switch circuit 8 on / off based on the dialed telephone number to transmit a dial signal by a DP signal,
Alternatively, a dial signal is generated by a PB signal based on the dialed telephone number and transmitted via the adder 18 and the speech network circuit 9. Reference numeral 22 denotes a RAM built in the control microcomputer 21. As shown in FIG. 2, there are provided first and second registration areas in which two sets of telephone numbers and transmission information for automatic transmission can be registered.

A method of registering a telephone number and transmission information for automatic transmission in the RAM 22 will be described. In a standby state, when the first registration button of the key matrix 20 and the dial button of "1" are simultaneously pressed, control is performed. The microcomputer 21 enters a telephone number registration mode for the first registration area of the RAM 22. Here, when dialing a contract telephone number for the pager dedicated to calling, for example, 03-5612-42xx, the control microcomputer 21 registers the telephone number for automatic transmission in the upper part of the first registration area. Thereafter, the registration mode is canceled by pressing the first registration button alone again. When you want to register the contract phone number and message number for the display pager in the second registration area,
When the registration button and the dial button of “2” are simultaneously pressed, a telephone number registration mode for the second registration area is set. Here, the contract telephone number, for example, 03-5612-42 @
When the dial is performed, the telephone number is registered as an automatic calling telephone number in the upper part of the second registration area. When the first registration button is pressed alone again to cancel the registration mode and the second registration button and the dial button of “2” are simultaneously pressed, a mode for registering transmission information to the second registration area is set. Here, as a message number, dial 51 which means "come",
When # is dialed as the end symbol, it is registered as transmission information in the lower part of the second registration area. Thereafter, when the second registration button is pressed alone, the registration mode is canceled. The telephone numbers and transmission information registered in the first registration area and the second registration area of the RAM 22 can be arbitrarily rewritten any number of times by the same operation.

Next, the operation of this embodiment will be described with reference to FIGS. FIGS. 4 and 5 are main flow charts showing the call control processing of the control microcomputer 21, and FIGS. 6 and 7 are flow charts showing the automatic call control processing executed by the control microcomputer 21 by interruption when the automatic call button is pressed. Here, for convenience of explanation, it is assumed that the processing of FIGS. 6 and 7 is executed by a hardware interruption in response to the pressing of the automatic transmission button. The RAM 22 and the ROM 2
3, three telephone numbers and transmission information are registered in advance as shown in FIGS. It is also assumed that flags A to F indicating various states of the telephone are all cleared.
The flag A is set to 1 during an incoming call, the flag B is set to 1 when the other party goes off-hook and disconnects the line during the incoming call, and the flag C is raised when the receiver 1 is lifted from the standby state and a dial tone is heard. The flag D is set to 1 when the dial tone is no longer heard after lifting the receiver 1 from the standby state, and the flag D ′ is set to 1 when the dial tone is no longer heard from the standby state.
Is lifted and dialed while the dial tone is being heard but not yet connected to the other party, the flag is set to 1, the flag E is set to 1 during an outgoing call, and the flag F is set to off-hook first during the outgoing call. It is set to 1 when the line is disconnected.

[0031]Automatic calling to pagers dedicated to calling
(During an incoming call) If a call is received while in the standby state, the ringer circuit 6
Rings. In addition, the incoming call detection circuit 11
And an incoming detection signal is sent to the control microcomputer 21.
Output to Control My with incoming call detection signal
The controller 21 determines YES in step 101 of FIG.
Then, since the user picks up the receiver 1, the hook switch
When the switch 19 is closed, the hook switch circuit 8 is controlled.
Go off-hook, close the line and talk
(Steps 102 and 103). At this time, during an incoming call
The first timer 15 and the second timer
Enable the timer 16 and the second timer
16 time counting operations are started (steps 104 to 1).
06). In the first timer 15, the sound detection circuit 14 is in a silent state.
Each time is detected, its duration t1 is counted. 2nd tie
The timer 16 measures the elapsed time t2 from the start of the call.

When a call is made, the polarity of the public telephone line changes, and the response detection circuit 13 outputs a response detection signal. The voice of the other party can be heard from the receiving speaker 3 of the receiver 1 via the speech network circuit 9. Also, one's own voice is transmitted to the line via the transmission microphone 2 and the speech network 9. Thereafter, the control microcomputer 21 detects whether the time count t1 of the first timer 15 has exceeded 10 seconds, whether the handset 1 has been placed on the telephone body 4 and the hook switch 19 has been opened, or the voice detection circuit 14 detects a busy tone.
It is repeatedly checked whether the other party disconnected (on-hook) the line first (steps 107 to 109).

If the other party is carrying a pager dedicated to calling and is out of the office, there is a requirement. If you want to call the party with a pager and convey the requirement, call the other party with a pager and contact the other party. After that, the automatic transmission button of the key matrix 20 and the dial button of "1" are sequentially pressed, and the receiver 1 is returned on the telephone main body 4. When the automatic transmission button is pressed, the control microcomputer 21 determines that the operation is an automatic transmission instruction operation, and executes the hardware interrupt processing of FIG. First, it is checked whether the next button pressed on the automatic call button is a dial button of "1" or "2" (step 301 in FIG. 6). Since YES, the telephone number is registered in the first registration area of the RAM 22. It is checked whether it has been performed (step 302). Young, no
In this case, since automatic transmission cannot be performed, the interrupt processing is completed and the process returns to the main flow in FIGS.

However, since YES is obtained in step 302, it is next checked whether any of the flags A, B, D, D ', E, and F is 1 (step 30).
3). Since A is 1, it is determined to be YES and an automatic transmission process is executed. That is, first, the hook switch circuit 8 is on-hook controlled to disconnect the line once (step 304), and then off-hook control is again performed to close the line (step 305). Note that closing a line here means not only that the line is in a connected state, but also that a dial tone is transmitted from the exchange to be in an outgoing state.
Subsequently, in the RAM 21, the telephone number 03-5612-42xx registered in the upper part of the first registration area indicated by the dial button "1" pressed after the automatic call button this time.
Is transmitted (step 306). When the center of the pager responds, the exchange switches the polarity of the public telephone line, and from this polarity switching, the response detection circuit 13 detects the response of the other party and outputs a response detection signal.

The center returns an announcement that the pager is calling the pager. Please hang up the phone and wait, and also emits a pager ringing radio to ring the pager carried by the instep. . As described above, during a call due to an incoming call, the line is disconnected, closed, and the contract telephone number is automatically transmitted simply by performing a simple automatic call instruction operation of sequentially pressing the automatic call button and one dial button. So, if the user
Once placed on the phone body 4 and then taken up again,
It saves the hassle of dialing a contract phone number.

The control microcomputer 21 determines in step 30
After 6, the input from the response detection circuit 13 is monitored for a certain period of time, and when a response detection signal indicating that the other party who has automatically transmitted the call has responded within the predetermined time is input (Y in step 307)
ES), it is checked whether transmission information is registered in the lower part of the first registration area of the RAM 22 (step 308).
If registered, a tone signal of a combination corresponding to the transmission information is generated, and a call is made to the public telephone line via the adder 18 and the speech network circuit 9 (step 309). Since it has not been done, it is determined NO in step 308, the on-hook control is performed on the hook switch circuit 8, and the line is disconnected (step 310). Then, the flags A to F are cleared (step 311). If the receiver 1 is placed on the telephone main body 4 and the hook switch 19 is opened, step 1 in FIG.
01 and enters the standby state (YE in step 312).
S) If the hook switch 19 is not open, the handset 1
Waits until it is placed on the telephone body 4 and enters a standby state.

If no response detection signal is input within a predetermined time in step 307 of FIG. 6, the control microcomputer 21 checks whether automatic transmission has been performed twice (step 313). In order to perform an automatic call, the line is disconnected, the line is closed, a dial signal is generated, and the call is automatically transmitted to the preceding telephone number (steps 304 to 304).
306). Then, it waits for the input of the response detection signal from the response detection circuit 13 for a predetermined time (step 307). If a response detection signal is input within a predetermined time, the process proceeds to step 308. If no response detection signal is input within a predetermined time, automatic transmission is performed twice. Perform on-hook control and disconnect the line.

In this way, if there is no response from the automatically called party, the automatic calling is performed again, so that it is possible to reliably send the call to the desired destination. In addition, after the automatic call, the line is automatically disconnected if there is a response from the other party and the automatic call is completed normally, or if the answer is not obtained from the other party after performing the automatic call twice. Thus, the line is not left in the closed state, and the user does not need to perform the line disconnection operation again.
After that, if the party who receives the call with a pager calls you, you can tell the business.

When the other party hangs up during a call due to an incoming call before the user performs an automatic calling instruction operation, the exchange issues a busy tone (BT tone), so that the voice detection circuit 14 controls the busy tone detection signal. Output to the microcomputer 21. At this time, the control microcomputer 2
1 judges that the other party has disconnected (on-hook) the line (NO in step 109 in FIG. 4), clears A, and sets B (step 110). In this state, before the receiver 1 is returned to the telephone main body 4, when the user sequentially presses the automatic transmission button and "1", the control microcomputer 21
Determines YES in steps 301 to 303 in FIG.
Since the automatic transmission process is performed in exactly the same way as in the case of = 1 (steps 304 to 313), it does not take time to call the pager. Also, when the handset 1 is placed and the hook switch 19 is opened without t1 exceeding 10 seconds and without performing an automatic transmission instruction operation, the control microcomputer 21 disconnects the line, clears A and B, and waits. Return to the state (NO in step 107 in FIG. 4, 108, 1
12, 113).

06). When the pager center responds, the switchboard
Switches the polarity of the public telephone line.
Response detection circuit 13 detects the response of the other party and detects the response.
Output a signal.

In the case of the display type, after the center responds, the center returns an announcement “This is XXXXX. Please press the number you want to convey” through the line. When the message number is transmitted, the message number is sent. A calling radio wave including the message number is emitted, and when no message number is transmitted, a calling radio wave not including the message number is emitted. In this way, during standby, the line is closed and the contract telephone number is automatically transmitted simply by performing a simple automatic call instruction operation, so that the user picks up the handset 1 to call a pager. There is no need to perform the troublesome operation of dialing the contract telephone number.

The control microcomputer 21 determines in step 30
After 6, the input from the response detection circuit 13 is monitored for a certain period of time (step 307). When a response detection signal indicating that the other party who automatically sent the call has answered within a certain period of time, 2 It is checked whether transmission information is registered in the lower part of the registration area (step 308).
Here, since the transmission information 51 # is registered, a tone signal of a combination corresponding to the transmission information 51 # is generated,
A call is made to the public telephone line via the adder 18 and the speech network circuit 9 (step 309). Then, on-hook control is performed on the hook switch circuit 8 to disconnect the line (step 310). Then, the processing returns to the standby state through the processing of steps 311, 312. As described above, when the message number is also registered in advance in association with the telephone number for automatic calling, the message number is automatically transmitted following the contract phone number, so that the user dials the message number. Saves time.

If a response detection signal is not input within a predetermined time in step 307, the control microcomputer 21 performs line disconnection, line closing, and dial signal generation in order to perform automatic transmission again. Then, the call is automatically sent to the previous telephone number (steps 313, 304 to 306). Then, it waits for the input of the response detection signal from the response detection circuit 13 for a predetermined time (step 307). If there is an input of a response detection signal within a predetermined time, the process proceeds to step 308, where transmission information is transmitted (step 309).
Then, the program proceeds to 310 via 13 to perform on-hook control on the hook switch circuit 8 to disconnect the line (step 3).
10). In this way, if there is no response from the automatically called party, the automatic calling is performed again, so that it is possible to reliably call the desired destination. In addition, after the automatic transmission, if there is a response from the other party and the automatic transmission is completed normally, or if the response is not obtained from the other party even after performing the automatic transmission twice, the line is automatically disconnected. So
This eliminates the need for the user to perform the line disconnection operation again.

After the response, the center emits a calling radio wave including the message number when the message number is transmitted, sounds the display pager carried by the user, and displays the message number on the display. The person who sees the message number 51 (meaning "come") can return to the company immediately.

When the receiver 1 is picked up by the user to make an automatic call to the pager (during an outgoing call) , the control microcomputer 21 proceeds to step 114 in FIG.
And proceeds to the flow of FIG.
Perform off-hook control to connect a line (step 201). Thereafter, the system waits for a 400 Hz dial tone from the exchange, and when a dial tone detection signal is input from the dial tone detection circuit 12, sets a flag C indicating that the line is closed and transmission is possible. (Step 202,
203). If the user does not dial the telephone number within a certain period of time, the tone changes to a busy tone (BT tone). In this case, the flag C is dropped and the flag D is set (step 204,
205), when the user dials an arbitrary telephone number within a predetermined time, the control microcomputer 21 transmits a dial signal and drops the flag C, and once the flag D '
Is set to indicate the off-hook state after the transmission, and when the response detection circuit 13 detects the response of the other party, the flag D 'is dropped and the flag E is raised to register that the call is in progress (step 206). To 210).

When it is necessary to call outgoing party A or B with a pager while talking with the other party, before placing the handset 1, the automatic call button and the dial button of "1" or "2" are set. Press in order to control microcomputer 2
1 executes the interrupt processing of FIG.
After determining YES in 02, since E is 1, it also determines YES in 303, and disconnects and closes the line, transmits a contract telephone number, transmits transmission information after detecting a response, and transmits a line in the same manner as during an incoming call. , Clear the flag, return to the standby state, and perform an automatic transmission process for calling the pager of Party A or Party B (steps 304 to 313). Therefore, the user does not need to perform a complicated pager calling operation.

If the other party hangs up first before performing the automatic calling instruction operation, the control microcomputer 21 drops the flag E and sets the flag F when the busy tone detection signal is input from the voice detection circuit 14. (Steps 212 and 213), and since YES is obtained in Step 303, the same automatic transmission processing as in the case of E = 1 is performed. A state in which the receiver 1 is simply lifted from the standby state, or
Even when the receiver 1 is lifted and dialed, but is not yet connected to the other party, the automatic transmission can be performed by sequentially pressing the automatic transmission button and the "1" or "2" dial button. That is, while the dial tone is being heard, the flag C = 1, so that YE is determined in step 314 of FIG.
If it is determined as S, transmission of a contract telephone number, transmission of transmission information after detecting a response, disconnection of a line, clearing of a flag, and return to a standby state are performed. After the dial tone is no longer heard without dialing while the receiver 1 is being lifted, or when the receiver 1 is dialed but not yet connected to the other party, the flag D = 1 or D '= 1, so step 303 Is determined as YES, and the same automatic transmission processing as in the case of E = 1 is performed.

In the meantime, once the receiver 1 is picked up from the standby state and the receiver 1 is put down without making a telephone call, or the receiver 1 is picked up and dialed, but the receiver 1 is put up without answering the telephone. When the receiver 1 is put down as it is after the outgoing call, the control microcomputer 21 disconnects the line, clears the flag and returns to the standby state (step 214 or 215 or 21 in FIG. 5).
6 or 211, 217, 218).

Automatic call to unwanted call refusal service
(During a telephone call) I picked up the receiver 1 because I got a call ,
When it is a prank call and the user wants to prevent a prank call from being made next time, he or she presses the automatic call button and the dial button of "3" in the call state, and returns the handset 1 to the telephone main body 4. The control microcomputer 21
When the automatic transmission button is pressed, the interruption processing of FIG. 6 is executed. This time, since the dial button “1” or “2” is not pressed after the automatic call button, step 30
1 is NO, the process proceeds to the flow of FIG. 7, and it is checked whether the dial button "3" is pressed (step 40).
1). Since the answer is YES, first, it is checked whether an incoming call is in progress at A = 1 (step 402). This is because it is unnatural to make a call to the nuisance call refusal service phone number when a call is made by the user and a call is in progress (E = 1),
This is because the automatic transmission instruction operation is ignored when the user performs an erroneous operation.

However, in this case, since a call is in progress due to an incoming call, it is checked whether the time t2 of the second timer 16 is equal to or shorter than a predetermined reference time T2 (step 40).
3). T2 is a minimum talk time required for a normal telephone that is not a prank, and is set to, for example, about 30 seconds. If t2 is equal to or longer than T2, it is considered that the user erroneously performed an automatic call instruction operation during a normal non-mischievous call. This is for ignoring the automatic transmission instruction operation.

When the user performs an automatic transmission instruction operation at time t2 = 10 seconds from the start of the call, t2 is equal to or less than T2, and the control microcomputer 21 determines in step 403 that YE
Judge as S. In this case, since it was considered a mischievous phone call, it is considered that an automatic call instruction operation was performed to receive the nuisance call refusal service.
First, first, the speech synthesis output circuit 17 is controlled to synthesize speech such as "Please stop mischief" and "Let's make a mistake" and output it to the public telephone line via the adder 18 and the speech network circuit 9. To repel the mischief (step 404). Subsequently, an automatic calling process for receiving a nuisance call refusal service is executed.

That is, first, the hook switch circuit 8 is controlled on-hook to disconnect the line once (step 405), and then off-hook control is again performed to close the line (step 406). Then, ROM23
A dial signal of a combination corresponding to the telephone number 144 registered in the upper part of the registration area is transmitted (step 407). When the exchange of the office answers, the exchange switches the polarity of the public telephone line, and the response detection circuit 13 detects the response of the other party (the exchange in the case of the nuisance call refusal service) from the polarity switching, and outputs a response detection signal. I do. The exchange returns a beep sound through the line.
In this way, during a call due to an incoming call, simply performing a simple automatic outgoing instruction operation will send out mischievous repulsion sound, disconnect the line,
Since the call to the telephone number 144 for receiving the closing and the nuisance call refusal service is automatically made, the user can use words such as "Please stop mischief" or "Please do not care" to repel the mischief call. It does not need to be emitted (if the user speaks with his / her own voice, it may promote mischief instead), and the receiver 1 is temporarily moved to the telephone body 4.
After that, the trouble of having to pick up and dial 144 again can be saved.

The control microcomputer 21 proceeds to step 40
After 7, the input from the response detection circuit 13 is monitored for a certain period of time (step 408). The tone signal corresponding to the transmission information 2 indicating the refusal service ON registered in the lower part of the area is generated, and the adder 18 and the speech network circuit 9 are generated.
Outgoing call to the public telephone line via
9). Then, on-hook control is performed on the hook switch circuit 8 to disconnect the line (step 410). Then, various flags A to F are cleared (step 41).
1) If the receiver 1 is placed on the telephone body 4 and the hook switch 19 is open, the process returns to step 101 in FIG. 4 to be in a standby state (YES in step 412). If the hook switch 19 is closed, the receiver 1 is turned off. Waiting to be placed on the telephone main body 4, it enters a standby state.

If no response detection signal is input within a predetermined time in step 408, the control microcomputer 21 disconnects the line, closes the line, and generates a dial signal in order to perform automatic transmission again. Go ahead and phone number 1
44 (steps 413, 405 to 40)
7). Then, the process waits for a response detection signal input from the response detection circuit 13 for a predetermined time (step 408). If the response detection signal is input within a predetermined time, the process proceeds to step 409 to transmit the transmission information 2, and then performs on-hook control on the hook switch circuit 8 to disconnect the line (step 4).
10) If there is no response detection signal input within a certain time,
After step 413, the process proceeds to step 410 to disconnect the line. As described above, when there is no response from the automatically called party (here, the exchange of the office), automatic calling is performed again, so that it is possible to reliably send a call to the desired destination. In addition, if there is a response from the other party after the automatic transmission and the transmission information 2 is transmitted and the automatic transmission is completed normally, or if no response is obtained from the other party after performing the automatic transmission twice, Since the line is automatically disconnected, the line is not left in a closed state, and the user does not need to perform a line disconnection operation again.

When the number 2 is transmitted after 144 is dialed from a certain telephone, the exchange of the office accepts the nuisance call refusal service ON and stores the telephone number of the person who made the prank call in the incoming call rejection memory. Then, even if the same caller calls the same number, the call will not be connected,
Announce to the caller that "Cannot connect due to circumstances".

When the other party hangs up during a call due to an incoming call before the user performs an automatic call instruction operation, the exchange issues a busy tone (BT tone), so that the voice detection circuit 14 controls the busy tone detection signal. Output to the microcomputer 21. At this time, the control microcomputer 2
1 judges that the other party has disconnected (on-hook) the line (NO in step 109 in FIG. 4), clears A, and raises B (step 110). In this state, when the user sequentially presses the automatic transmission button and "3" before returning the handset 1 to the telephone body 4, the control microcomputer 21 determines YES in step 414 of FIG. At this time,
The control microcomputer 21 omits the output of the synthesized sound, proceeds to step 405, disconnects and closes the line, transmits 144, transmits 2 after detecting the response, disconnects the line, and flags A to F
Clearing and returning to the standby state are automatically performed (steps 406 to 413), so that troublesome use of the nuisance call refusal service is not required.

Automatic call to unwanted call refusal service (No
When a silent call is received, the control microcomputer 21 automatically sends a nuisance call refusal service even if the user does not perform an automatic call instruction operation. That is, during a call due to an incoming call, when the silence state of the other party lasts for 10 seconds and the time t1 of the first timer 15 reaches 10 seconds, the control microcomputer 21 proceeds to step 1 in FIG.
07 is determined as YES. At this time, the control microcomputer 21 determines the elapsed time t2 measured by the second timer 16
Check if is within T2. When it exceeds T2,
Since the talk time is long and the caller, not the prank call, is required to temporarily leave his / her seat, the silent state is considered to have continued, so the occurrence of the silent state this time is ignored (NO in step 111). Only when t2 is within T2, it is determined to be YES in step 111, and it is treated that a silent call has been received, and in the same manner as described above, output of voice synthesis sound, line disconnection, line disconnection, 144 , Transmission of 2 when there is a response from the exchange, disconnection of the line, clearing of the flag, and return to the standby state are sequentially performed (steps 404 to 412 in FIG. 7). Thereby, when a silent prank call is received, a nuisance call refusal service can be received without the user performing an automatic call instruction operation, which is convenient.

Automatic call to the nuisance call refusal service (wait
When a mischievous phone call is received, the handset 1 is
Even after the mobile phone is in standby mode, it is possible to receive an unwanted call refusal service by performing an automatic call instruction operation before another call is received. When the automatic transmission button and the dial button of "3" are sequentially pressed, the control microcomputer 21 executes the interrupt processing of FIGS. 6 and 7, and determines NO in step 301 and YES in step 401 of FIG. Then, since all of the flags A to F are cleared, the process proceeds to step 406, and after closing the line, 144 is transmitted (step 407). Then, it waits for a response detection signal from the response detection circuit 13 for a predetermined time (step 408). If a response detection signal is input within a predetermined time, the flow advances to step 409 to transmit 2, clear the flags AF after disconnecting the line, and return to the standby state (steps 410 to 412). Thus, the user can receive the nuisance call refusal service by simply performing an automatic call instruction operation in the standby state, picking up the receiver 1, dialing 144, transmitting 2, and then receiving the call. It is not necessary to perform the troublesome operation of returning 1 to its original state.

If no response detection signal is input within a predetermined time in step 408, the control microcomputer 21
Disconnects the line once, closes the line again, transmits a signal 144, and waits for the input of a response detection signal (step 41).
3, 405-408). If there is a response detection signal input,
After the transmission of No. 2, the line is disconnected, the flag is cleared, and the process returns to the standby state (steps 409 to 412). If no response detection signal is input within a predetermined time, the line is disconnected.
Clear the flag and return to the standby state (step 413,
410-412). The central office switches to 144 from a certain telephone
When 2 is sent after is dialed, the unwanted call refusing service is accepted, the phone number of the person who made the mischief call immediately before is memorized, and then the same caller calls the same number. When the call arrives, the call is not connected, and an announcement is sent to the caller stating that the connection cannot be made due to circumstances.

Automatic call to unwanted call refusing service ( E
(Hook state) After the receiver 1 is picked up from the standby state, when the user sequentially presses the automatic call button and the dial button of "3" while the dial tone is being heard, the control microcomputer 21
Executes the interrupt processing of FIGS. here,
Since the flag C = 1, YES is determined in step 415,
Immediately, 144 is transmitted, and after detecting a response, 2 is transmitted. After disconnecting the line, the flag is cleared and the process returns to the standby state (steps 407 to 413). On the other hand, handset 1
Then, when the dial tone of "3" is pressed in order after the dial tone is no longer heard, the control microcomputer 21 determines YES in step 414 of FIG. At that time, after disconnecting the line, re-closing, send 144, and after detecting the response,
2 is transmitted, the line is disconnected, the flag is cleared, and the process returns to the standby state (steps 405 to 413).

Further, after picking up the receiver 1 from the standby state to consult a friend or the like about a prank call made immediately before, a certain number is dialed, but since the other party does not readily answer the call, an automatic call button and " When the dial buttons of "3" are sequentially pressed, since D '= 1, the control microcomputer 21 determines YES in step 414 of FIG.
Is transmitted, and after detecting a response, 2 is transmitted. After disconnecting the line, the flag is cleared and the process returns to the standby state (step 405).
413). In this manner, when the receiver 1 is lifted from the standby state and is in the off-hook state, it is possible to automatically make a call to the nuisance call refusal service only by performing a simple operation of instructing an automatic call, so that the user's labor is greatly reduced. You.

During an outgoing call or during an outgoing call, when the other party is in an off-hook state after first hanging up (E
Or F = 1), since it is unnatural to receive the nuisance call refusal service, the control microcomputer 21 ignores the automatic transmission instruction even if the user sequentially presses the automatic transmission button and “3” (FIG. (YES in step 416 of FIG. 7).

In the above-described embodiment, when transmission information such as a message number is added to the telephone number for automatic transmission, the transmission information is checked after confirming the response of the destination from the output of the response detection circuit at the time of automatic transmission. However, after sending a phone number for automatic calling, the sending information is automatically sent after a certain period of time, regardless of whether the other party responds, and then the line is disconnected. In this case, the response detection circuit becomes unnecessary. Also, during an incoming call, when an automatic calling instruction operation for receiving the nuisance call refusal service is performed, the automatic calling process may be performed without checking the step 403 in FIG. If the mute state continues for a certain period of time and the result of step 107 in FIG.
The automatic transmission processing may be performed as it is without checking. In step 107, it is checked whether the time has exceeded 10 seconds. However, another time such as 15 seconds or 20 seconds may be used, or the user may arbitrarily set the time.

Further, the telephone number and transmission information for receiving the nuisance call refusal service are registered in the registration area of the ROM 23 in advance. However, a third registration area is provided in the RAM 22, and the registration is performed according to the user's registration operation. You may be able to. Further, the telephone number 144 for canceling the nuisance call refusal service is associated with the transmission information 9 in the ROM.
23, for example, an automatic call button and "0"
When the dial buttons are sequentially pressed, after disconnecting or closing the line in the same manner as described above, first, an automatic transmission of 144 is performed, and then, 9 is transmitted after automatic or response detection,
Then, if the line is disconnected, the unwanted call refusing service can be canceled by a simple operation.

Also, the state of the telephone is managed by a flag, and the manner of automatic transmission is changed according to the state of the telephone. When the silent state of
Regardless of whether the line is disconnected, closed, transmitted a telephone number, transmitted transmission information after detecting a response, disconnected, or returned to the standby state, any In this case, it is possible to make an automatic call, and when the automatic call instruction operation is performed, the line is closed, the telephone number is transmitted, the transmission information is transmitted after the response is detected, the line is disconnected, and the line returns to the standby state. , The call can be automatically transmitted from the standby state.

Further, in the above-described embodiment, the telephone number for using the pager service and the nuisance call refusal service can be automatically transmitted. However, the present invention is not limited to this, and the present invention is not limited to this. Automatic calling to use the telephone service of the present invention (in the case of the dual number service, 141 is a telephone number and 1 is transmission information), or a personal telephone can be automatically dialed to a specific telephone number. good.

According to the present invention, a predetermined telephone number is registered in the registration means, and when the voice of the other party is not detected for a certain period of time by the detection means during a call, the line is temporarily disconnected. After that, the phone is closed again, and the call is made automatically by sending the predetermined telephone number registered in the registration means. Therefore, when a silent call is made, the line is not required for the user to perform any special operation. A series of automatic calling operations such as disconnection, closing, and transmission of a predetermined telephone number can be performed, and dialing to a nuisance call refusal service can be performed completely automatically.

According to still another aspect of the present invention, when automatic transmission is instructed, a predetermined voice synthesis sound is output from the voice synthesis output means to the line before the automatic transmission means performs the automatic transmission operation. So, when you got a prank call,
For example, it is possible to respond with voice synthesis sounds such as "Please stop mischief" and "Let's make a mistake", and it is not necessary for the user to respond with a real voice, and the mechanically synthesized sound has a prank repulsion effect Can also.

According to another aspect of the present invention, automatic transmission is not performed when it is not determined that a call is in progress due to an incoming call. It is possible to prevent an erroneous automatic call to a predetermined telephone number when, for example, a call instruction operation is performed erroneously, or when the other party answers the telephone and temporarily leaves the telephone as required.

According to another aspect of the present invention, even if it is determined that a call is in progress due to an incoming call, if the elapsed time from the start of the call is longer than a predetermined time, automatic calling is prevented from being performed. Even if you are on a call, if you are a regular phone instead of a mischievous phone, you will talk for a certain period of time or more. In such a case, it is possible to prevent an automatic call to a predetermined telephone number by mistake.

According to another aspect of the invention, the registration means also registers predetermined transmission information together with a predetermined telephone number,
When sending an automatic call, after sending a predetermined telephone number registered in the registration means, predetermined transmission information is also transmitted, so, for example, a message number in the case of a display type pager service, a nuisance call rejection service In this case, a number indicating that the service is turned on can also be automatically transmitted.

According to another aspect of the invention, the registration means also registers predetermined transmission information together with a predetermined telephone number.
When the response detection means detects a response from the destination of the automatic call, the predetermined transmission information registered in the registration means is transmitted, so that, for example, a message number in the case of a display type pager service, annoying In the case of the call refusal service, a number indicating that the refusal service is on can be automatically transmitted.

According to another aspect of the present invention, the line is disconnected after the automatic transmission is completed or when no response is detected from the destination of the automatic transmission by the response detection means. Even if the user does not perform the line disconnection operation, it is possible to prevent the line from being left closed.

According to another aspect of the present invention, when the response detecting means does not detect a response from the automatic transmission destination,
Since automatic transmission is performed again, automatic transmission to a predetermined telephone number can be reliably performed.
