Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device connected to an exchange for notifying the receiving side of information of the calling side when the calling side makes a call.

[0002]

2. Description of the Related Art In recent years, a caller telephone number notification service has been implemented to notify the called party of the caller's telephone number when the caller makes a call. In a telephone device connected to an exchange capable of providing such a caller telephone number notification service, when the caller telephone number notified from the exchange side upon receiving a call is received, it is displayed on the display unit, and no one is notified to the user. I am trying to inform you if it is an incoming call.

When it is found that the call is a nuisance call such as a prank call after answering the incoming call, the caller telephone number notified from the exchange side together with the incoming call is registered in a memory or the like, and the same caller is called next time. When an incoming call based on the call arrives, the incoming call based on the caller's call can be rejected by matching the telephone number with the registered telephone number in the memory.

[0004]

Generally, nuisance calls such as solicitations are often made from a plurality of lines having different subscriber numbers. In such a case, even if one subscriber number, that is, one caller telephone number is registered in the memory as the telephone number of the nuisance call as in the conventional example, the same caller can call from another line. When calling, the caller's telephone number at this time does not match the registered telephone number in the memory, and thus such a nuisance call is tolerated.

Therefore, an object of the present invention is to accurately reject a nuisance call such as a solicitation.

[0006]

In order to solve such a problem, the present invention provides a telephone device connected via a line to an exchange capable of notifying the information of the calling side to the called side when the calling side makes a call. In addition, the receiving means for receiving the information of the calling side notified from the exchange at the time of the incoming call, the information registration section in which the information of the calling side which should reject the incoming call is registered as rejection information, and the information registration section are registered. At least one of the telephone number and the sender name is compared by comparing the telephone number and the sender name included in the sender information with the telephone number and the sender name included in the sender information received by the receiving means. Incoming call rejection means is provided to reject incoming calls when they match.

In this case, there is provided registration means for registering information on the calling side in the information registration section as the rejection information in response to an incoming call which is not rejected by the incoming call rejection means, in response to a predetermined operation during the call or after the end of the call. Be prepared.

Further, a keyword information registration section is provided in which name information forming part of the sender's name is registered in advance as keyword information, and the call rejection means forms part of the sender's name received by the receiving means. If the name information to be registered is registered in the keyword information registration unit, the incoming call is rejected.

Further, the telephone device is composed of a plurality of telephones such as a cordless telephone device or a key telephone device, and an incoming call table in which a telephone in which an incoming call is distributed in association with information on the calling side is registered in advance and an incoming call rejection means are provided. An incoming call allocating means for allocating an unrejected incoming call to a telephone set according to registered information in the incoming call table is provided.

The destination exchange 200 shown in FIG. 5 receives 16H in step S1 prior to receiving an incoming call to the destination telephone device 10B.
The reception terminal activation signal of z is sent to the destination telephone device 10B. Then, the receiving-side telephone device 10B detects this receiving terminal activation signal and closes the DC loop of the line in step S2 (primary response signal). When the destination exchange 200 recognizes the response from the destination telephone device 10B by the primary response signal based on the line DC loop closure, the destination telephone device 10A's telephone number and the sender's name described above are transmitted by a modem signal. The destination telephone device 10B is notified in step S3.

The destination telephone device 10B includes a destination exchange 200.
When the telephone number and the caller's name of the calling side telephone device 10A notified from are received, the DC loop of the closed line is opened in step S4 (reception completion signal). Destination switch 2
When detecting the reception completion signal, 00 sends a 16 Hz ringing signal to the destination telephone device 10B in step S5. This call signal causes the receiving side telephone device 10B to ring,
When the DC loop of the line is closed by, for example, off-hook of the destination telephone device 10B, the line DC loop closure is transmitted to the destination exchange 200 as a secondary response signal in step S6. Recognize the incoming call response of the telephone device 10B. Therefore, the originating telephone device 10A notified from the destination exchange 200 on the destination telephone device 10B side.
By displaying the telephone number and the caller's name on the display unit, it is possible to easily identify the incoming call from the receiving side telephone device 10B before answering the incoming call.

Next, FIG. 6B is a sequence diagram showing the operation in the case of the ISDN line. In the case of an ISDN line, when receiving a call to the destination telephone device 10B, first, the destination exchange 2
00 to "CNG"("Calling party number information element") and "C
RI-INV (Caller RelatedInfomation-INV) "(caller related character information operation) included" FAC "
(“Facility”) information element and “SETU
"P"("callsetting" message) is transmitted to the destination telephone device 10B via the ISDN line in step S11.

Then, the destination telephone device 10B identifies this "call setup" message and calls "CALPLPROC".
(“Call setting acceptance” message) is transmitted to the destination exchange 200 in step S12, and then step S1.
In 3 and S14, "ALERT"("call" message) and "CONN"("response" message) are transmitted to the destination exchange 200, respectively. Upon receiving these messages, the destination exchange 200 receives "CONNACK".
(“Response confirmation” message) is returned to the destination telephone device 10B. Therefore, on the receiving side telephone device 10B side, the calling number (caller telephone number) in the "calling number information element" and the "CRI" of the "facility" information element included in the "call setting" message from the receiving side exchange 200. If the caller name in "-INV" is displayed on the display unit, the called-side telephone device 1
On the 0B side, it is possible to easily identify who is the incoming call before answering the incoming call.

FIG. 7 is a flowchart showing the operation of the destination telephone device 10B connected to the destination exchange 200.
The main operation of the present invention will be described with reference to this flowchart. Here, as the destination telephone device 10B connected to the destination exchange 200, any of the telephone device 10 of FIG. 1A, the cordless telephone device of FIG. 2A and the button telephone device of FIG. 3 may be used. First, in the first embodiment, the operation when the telephone device 10 of FIG. 1A is used as the destination telephone device 10B will be described.

(First Embodiment) Calling side telephone device 10A
If there is an incoming call from the side and the determination of "incoming call?" In step S1 becomes "Y", the control unit 3 receives the information of the outgoing side notified from the destination exchange 200 in step S2.
Then, in step S3, it is determined whether or not the received sender information includes the sender name. Here, if the received information on the calling side does not include the calling party name, other incoming processing is performed in step S4, and the process ends.

On the other hand, if the received information on the caller side includes the caller's name, then "Yes?" In step S3 is "Y". Is executed in step S4. Then, as a result of the incoming call rejection search processing, if the incoming call is not rejected, the "incoming call rejection?" In step S6 becomes "N", so that the process proceeds to step S7 to determine the incoming call distribution. Since this incoming call distribution is to distribute the incoming call to any of a plurality of telephones and is not applied to a single telephone such as the telephone device 10 of FIG. 1A, "Negative call distribution?" In step S7 is "N". , And the process proceeds to step S9, and the normal incoming call process is performed.

In this normal incoming call processing, the control unit 3 displays the received information on the calling side on the display unit 5 and causes the buzzer 6 to ring the incoming call. Then, when the user notices the incoming call by this ringing tone and goes off-hook to answer the incoming call, the user makes an incoming call response call. When the user recognizes that the call is a nuisance call such as solicitation during a call with the other party, the user operates a predetermined key in the function keys 8.
Then, the control unit 3 registers the received information (caller telephone number, caller name) on the calling side in the search information unit 4A in the memory 4. Then, the call is terminated by the user's on-hook.

When an incoming call arrives again at the telephone device 10 after the call is completed in this way, similarly, the information of the calling side is received in step S2 after "Y" of "incoming call?" In step S1. Then, if the received information on the caller side includes the caller's name, the control unit 3 performs an incoming call rejection search process in step S5.

In this incoming call refusal search process, a search process based on the information registered in the search information section 4A of the memory 4 is performed. That is, the control unit 3 first performs, as a first search process, a process of determining whether the received caller name is registered in the search information unit 4A, and if it is registered, rejects the incoming call. . As a result, the incoming call rejection process is performed in step S10 after "Y" of "incoming call rejection?" In step S6. Therefore, even if the caller recognized by the user as the source of the nuisance call at the time of the last incoming call, the caller name is the same even if the caller is called again from a line different from the previous line, The sender name registered in the search information section 4A last time matches the sender name this time. This makes it possible to accurately reject nuisance calls such as solicitations from the same caller coming from different lines. If the received sender name is not registered in the search information section 4A, the second search process is performed.

In the second search process, it is determined whether or not the received information on the calling side matches either the calling telephone number or the calling name registered in the search information section 4A. Here, if the received information of the calling side matches either of the calling party telephone number and the calling party name registered in the search information section 4A, the incoming call is rejected, whereby step S1
When 0, incoming call rejection processing is performed. If the received information on the calling side does not match the calling party telephone number or the calling party name registered in the search information section 4A, the third searching process is performed.

In the third search processing, it is determined whether the received sender name matches the keyword registered in the search information section 4A in advance. Here, the received caller name is, for example, XX company, and the name information "XX" and "company"
Control unit 3 extracts only "company" from the sender name without the above "○○", and compares it with the keyword registered in the search information unit 4A. . Then, when the keyword of the search information section 4A corresponds to the name information "company" that constitutes a part of the received caller name, the incoming call is rejected. In this way, if the caller name does not completely match the received caller name but partially matches, the incoming call is rejected. As a result, the incoming call rejection process is performed in step S10 after "Y" of "incoming call rejection?" In step S6.

In the incoming call rejection process of step 10, any one of the following first to third processes is performed. In the first process, a process of not ringing a ring tone, that is, a process of continuing silence during a call is performed. Therefore, the silent state continues unless the other party hangs up. In the second process, the line is automatically disconnected immediately after automatically answering the incoming call. In the third processing, after automatically answering the incoming call, a voice synthesis circuit (not shown) is driven to send a predetermined message to the calling side, and then the line is automatically disconnected.

After performing such a call rejection process, the control unit 3 registers the received caller information (caller telephone number, caller name) in the call rejection list unit 4B of the memory 4 in step S11. . In this way, the information registered in the incoming call refusal list unit 4B is used when comparing with the information on the calling side received at the next incoming call. That is, when the next incoming call is judged to be "Y" in "Yes with name?" In step S3, first, the match with the registration information in the incoming call rejection list section 4B is compared, and when the comparison result shows a mismatch. The incoming call rejection search process of step S5 described above is performed. Note that the process of comparing the information on the calling side received at the time of an incoming call with the registered information in the incoming call rejection list unit 4B may be unnecessary. In this case, the process of step S11 becomes unnecessary.

(Second Embodiment) In the second embodiment, the operation when the cordless telephone device of FIG. 2A is used as the destination telephone device 10B will be described.
When there is an incoming call from the calling side telephone device 10A side and the judgment of “incoming call?” In step S1 of FIG. 7 is “Y”, the control unit 24 of the parent device 20 causes the calling side exchange 200 to notify the calling side. Information is received in step S2. Then, in step S3, it is determined whether or not the received sender information includes the sender name. Here, if the received information on the calling side does not include the calling party name, other incoming processing is performed in step S4, and the process ends.

On the other hand, if the sender's name is included in the received information on the calling party side, "Yes?" In step S3 becomes "Y", so that the incoming call rejection search processing is performed in step S3.
Run with 4. Then, as a result of the call rejection search processing,
In the case of an incoming call that is not rejected, the "incoming call rejection?" In step S6 becomes "N", so that the process proceeds to step S7 to determine the incoming call distribution. Here, if the incoming call table 25C is provided in the memory 25, "incoming call distribution?" In step S7 becomes "Y", and the process proceeds to step S8 to execute the incoming call distribution process according to the registered data in the incoming call table 25C. To do.

In this incoming call distribution processing, the control unit 24
Compares the received caller telephone number (or caller name may be used) with the caller phone number (or caller name may be used) registered in the incoming table 25C, and when the two match. The buzzer of the corresponding ringing telephone set (i.e., the master unit 20 or the slave unit 30) of the incoming call table 25C is ringed, and the received information of the calling side is displayed on the display unit of the ringing ring unit. When the user notices the incoming call by the ringing tone and goes off-hook to answer the incoming call, the user makes an incoming call response call. When the user recognizes that the call is a nuisance call such as solicitation during a call with the other party, the user operates a predetermined key in the function keys. Then, the control unit 24 registers the received information on the calling side in the search information unit 25A in the memory 25. Then, the call is terminated by the user's on-hook.

When an incoming call arrives at the cordless telephone device again after the call is finished in this manner, the same step S1 is performed.
After "Y" of "Are there any incoming calls?", The information of the calling side is received in step S2. Then, if the received information on the caller side includes the caller name, the control unit 24 performs a call rejection search process in step S5.

That is, the control unit 24 first performs a process of determining whether or not the received caller name is registered in the search information unit 25A as the first search process, and if it is registered, the incoming call is received. Refuse to As a result, step S6
After "Y" of "Call rejection?", The call rejection processing is performed in step S10. Therefore, even if the caller recognized by the user as the source of the nuisance call at the time of the last incoming call, the caller name is the same even if the caller is called again from a line different from the previous line, The sender name previously registered in the search information section 25A matches the sender name this time. This makes it possible to accurately reject nuisance calls such as solicitations from the same caller coming from different lines. The received sender name is the search information section 25.
If not registered in A, the second search processing is performed.

In the second search process, it is determined whether or not the received information on the calling side matches either the calling party telephone number or the calling party name registered in the search information section 25A. Here, if the received information of the calling side matches any of the registered caller telephone number and caller name, the incoming call is rejected, whereby the incoming call rejection processing is performed in step S10. If the received information on the calling side does not match the calling party telephone number or the calling party name registered in the search information section 25A, the third searching process is performed.

In the third search processing, it is determined whether the received caller name matches the keyword registered in the search information section 25A in advance. Here, if the received caller name matches the keyword of the search information section 25A, the control section 24 determines that
Reject the call. As a result, the incoming call rejection process is performed in step S10 after "Y" of "incoming call rejection?" In step S6.

In the incoming call rejection processing of step 10,
Any of the third processing is performed. In the first process, a process of not ringing a ring tone, that is, a process of continuing silence during a call is performed. Therefore, the silent state continues unless the other party hangs up. In the second process, the line is automatically disconnected immediately after automatically answering the incoming call. In the third process,
After automatically answering the incoming call, a voice synthesizing circuit (not shown) is driven to send a predetermined message to the calling side, and then the line is automatically disconnected. After the termination of the incoming call rejection processing, the control unit 24 sends the information of the calling side to the step S11 if necessary.
Then, it is registered in the incoming call rejection list section 25B of the memory 25.

(Third Embodiment) Next, in the third embodiment, the operation when the key telephone device of FIG. 3 is used as the destination telephone device 10B will be described. When there is an incoming call from the originating telephone device 10A side and the determination of “incoming call?” In step S1 of FIG. 7 is “Y”, the control unit 54 of the main device 50 causes the calling side exchange 200 to notify the originating side. Information is received in step S2. Then, in step S, it is determined whether or not the sender information is included in the received sender information.
Judge with 3. Here, if the received information on the calling side does not include the calling party name, other incoming processing is performed in step S4, and the process ends.

On the other hand, if the received information on the caller side includes the caller's name, since "Yes?" In step S3 becomes "Y", the incoming call rejection search process is executed in step S3.
Run with 4. Then, as a result of the call rejection search processing,
In the case of an incoming call that is not rejected, the "incoming call rejection?" In step S6 becomes "N", so that the process proceeds to step S7 to determine the incoming call distribution. Here, if the incoming call table 55C is provided in the memory 55, "incoming call distribution?" In step S7 becomes "Y", and the process proceeds to step S8 to execute the incoming call distribution process according to the registered data of the incoming call table 55C. To do.

In this call distribution process, the control unit 54
Compares the received caller telephone number (or caller name may be used) with the caller telephone number (or caller name may be used) registered in the incoming table 55C, and when the two match. Buzzer 66 of the corresponding ringing telephone (that is, ringing slave) of the incoming call table 55C of
Is ringed and the received information of the calling side is displayed on the display unit 65 of the ringing slave. When the user notices the incoming call by the ringing tone and goes off-hook to answer the incoming call, the user makes an incoming call response call. When the user recognizes that the call is a nuisance call such as solicitation during a call with the other party, the user operates a predetermined key in the function keys 68. Then, the control unit 54 registers the received information on the calling side in the search information unit 55A in the memory 55. Then, the call is terminated by the user's on-hook.

When the incoming call arrives at the key telephone device again after the call is completed in this way, the information on the calling side is received in step S2 after "Y" of "incoming call?" In step S1. Then, if the received information on the caller side includes the caller name, the control unit 54 performs a call rejection search process in step S5.

That is, the control unit 54 first performs a process of determining whether or not the received caller name is registered in the search information unit 55A as the first search process, and if it is registered, the incoming call is received. Refuse to As a result, step S6
After "Y" of "Call rejection?", The call rejection processing is performed in step S10. Therefore, even if the caller recognized by the user as the source of the nuisance call at the time of the last incoming call, the caller name is the same even if the caller is called again from a line different from the previous line, The sender name registered in the search information section 55A last time matches the sender name this time. This makes it possible to accurately reject nuisance calls such as solicitations from the same caller coming from different lines. The received sender name is the search information section 55.
If not registered in A, the second search processing is performed.

In the second search process, it is determined whether or not the received information on the calling side matches either the calling telephone number or the calling name registered in the search information section 55A. Here, if the received information of the calling side matches any of the registered caller telephone number and caller name, the incoming call is rejected, whereby the incoming call rejection processing is performed in step S10. If the received information on the calling side does not match the calling party telephone number or the calling party name registered in the search information section 55A, the third searching process is performed.

In the third search processing, it is determined whether the received sender name matches the keyword registered in the search information section 55A in advance. Here, if the received sender name matches the keyword of the search information section 25A, the control section 54
Reject the call. As a result, the incoming call rejection process is performed in step S10 after "Y" of "incoming call rejection?" In step S6.

In the incoming call rejection processing in step 10,
Any of the third processing is performed. In the first process, a process of not ringing a ring tone, that is, a process of continuing silence during a call is performed. Therefore, the silent state continues unless the other party hangs up. In the second process, the line is automatically disconnected immediately after automatically answering the incoming call. In the third process,
After automatically answering the incoming call, a voice synthesizing circuit (not shown) is driven to send a predetermined message to the calling side, and then the line is automatically disconnected. After the completion of the incoming call rejection process, the control unit 54 outputs the information of the calling side in step S11 if necessary.
Then, it is registered in the incoming call rejection list section 55B of the memory 55.
