Abstract

PROBLEM TO BE SOLVED: To eliminate a complicated operation by providing a caller information obtaining means and a caller number report presence judging means and reproducing a previously prepared message unless a caller number is reported by means of the judging means. SOLUTION: When the telephone number of a caller via a line control part 105 is obtained, it is judged whether or not the caller telephone number is included as a parameter kind. When it is judged that the caller number is included, a telephone directory database stored in a storage part 104 is retrieved with the caller number as a key. It is judged whether or not the caller is a reliable opposite party and calling sound is issued so as to permit a user to know an incoming call at the time of the reliable opposite party. In the meantime, unless the telephone number of the opposite party is in the telephone directory database, it is judged that the opposite party is unreliable, a control part 105 is operated so as to form a current loop in a telephone line and to execute call-incoming and a response message storing part 106 is operated so as to reproduce 'an incoming call is rejected' as against the opposite party and to transmit it.

Description

Detailed Description of the Invention

[0001]

The present invention relates to a communication device such as a telephone.

[0002]

2. Description of the Related Art In recent years, caller ID notification services are being provided even in analog telephone networks. In Japan, NTT started a test service in 1996 and plans to start full-scale service in 1997.

FIG. 8 is a sequence diagram showing an example of a procedure for notifying a caller number, and TTC (Telephone and Telephone Technical Committee)
Is in the process of standardization.

In FIG. 8, reference numeral 801 denotes a receiving terminal, and 802.
Is a subscriber line exchange, and 803 to 811 are sequences. In these sequences, sequences 804-8
Up to 08 is a procedure newly added for calling party number notification, and the other sequence is the same as the procedure for receiving a call between a normal analog telephone and a subscriber line exchange.

In FIG. 8, when the caller number is notified to the receiving terminal 801, first, in a sequence 803, the subscriber line exchange 802 reverses the polarity of the telephone line, and the receiving operation of the receiving terminal 801 is started. Notify the start. Next, in a sequence 804, the subscriber line exchange 802 outputs an ID receiving terminal activation signal to notify the receiving terminal 801 that the calling party number and other information will be output.
Here, the ID receiving terminal activation signal is a signal in which a signal having a voltage of 75 volts and a frequency of 16 hertz is transmitted for 0.5 seconds and then the transmission is suspended for 0.5 seconds.

Receiving the ID receiving terminal activation signal, the receiving terminal 801 notifies the subscriber line exchange 802 that the ID receiving terminal activation signal is accepted by forming a current loop in the telephone line in sequence 805. Incoming terminal 8
When 01 receives the ID receiving terminal activation signal, the subscriber line exchange 802 notifies the receiving terminal 801 of the caller number and other information in sequence 806 (the format of the information notified at this time will be described later). To). Receiving the caller number and other information, the receiving terminal 801 displays the caller number and performs other operations.

Next, the receiving terminal 801 sends the sequence 80
In step 7, the current loop formed in the sequence 805 is disconnected, and the subscriber line exchange 802 is notified that the reception is completed. In response to this, the subscriber line exchange 802
Outputs a call signal in sequence 808. Receiving the call signal, the receiving terminal 801 performs an operation such as ringing a ring tone. Here, when the user performs a response operation such as lifting the handset, the current loop is formed again in sequence 809, and the subscriber line exchange 802 is notified that the user of the receiving terminal 801 has responded. In response to this, the subscriber line exchange 802 restores the polarity of the telephone line which was inverted in the sequence 803 in the sequence 810. As a result, in step 811, the receiving terminal 801
A call-in-progress state is formed between the switch and the subscriber line exchange 802, and the call is started.

FIG. 9 is a diagram showing an example of a format of information notified from the subscriber line exchange 802 to the receiving terminal 801 in the sequence 806 of FIG. In the figure, SOH is Start of Header, S
TX is Start of Text, EXT is End
of Text, BCC is Block Check C
Abbreviation for character.

In FIG. 9, 900 indicates the format of the entire information. From the subscriber line exchange 802 to the communication terminal 801
The information notified to is the first header start character 90.
1, a header 902 following this, a text start character 903 indicating the start of the text portion, and a text portion 90.
4, a text end character 905 indicating the end of the text portion, and a block check character 906 for determining whether or not the entire information has been reliably transmitted.

Further, reference numeral 910 in FIG. 9 shows the format of the text portion 904 in the format 900 of the entire information. The text portion 904 includes a message type 911 indicating the type of information to be notified, a message length 912 indicating the length of the information to be notified, and a plurality of parameters 913, 914, and 915 following the message length 912. . The parameters 913 to 915 are the parameters 913.
It is repeated until the total length of ˜915 becomes the length specified by the message length 912.

Further, reference numeral 920 in FIG. 9 denotes a parameter 913 in the format 910 of the text portion 904.
~ 915 format is shown. Parameter 913 is
It is composed of a parameter type 921 indicating a parameter type, a parameter length 922 indicating a parameter length, and a parameter value 923 such as a sender number. Here, as the parameter type 921, the caller telephone number and the reason for not giving the ID are defined. In addition, there are three types of ID non-notification reasons: P notification, O notification, and C notification. P notification is "the sender rejects the number notification" and O notification is "the number is changed by the service of the calling side. I can't notify you "and C
The notification indicates “not allow notification by calling from public telephone”, respectively. That is, when the number notification is not made, the receiving side can know the reason.

By the way, the caller ID notification service is
If the caller makes a normal call without performing any action, the caller ID is notified by default. If the caller does not want to notify the caller of the caller ID,
Reject caller ID notification by dialing a special area code (for example, "184" in the test service started in 1996) before the other party's phone number and then dialing the other party's phone number be able to.

In this case, the receiving terminal is notified of the P notification, that is, "the sender rejected the number notification" instead of the sender number.

At the receiving terminal, the reason why the caller's number is not notified is that the caller refuses to notify the caller's number, or even if the caller's number is notified, it cannot be remembered at all. If the number is a number, there is a high possibility that the caller has a malicious call such as a mischievous call, and accordingly, a measure such as not responding will be taken.

Conventionally, in a telephone device accommodating at least one outside line, a caller number information signal receiving means for receiving a caller number information signal, a reception error detecting means for detecting a reception error, and the reception error. When the reception means detects a reception error, the control means is arranged so as to shift to a normal incoming call state or not to ring the incoming call.

[0016]

However, in the above-described conventional communication device, the caller makes a call whether or not the caller number is notified each time there is an incoming call and, if not, the reason why the caller number is not notified. The problem is that the operation is complicated because it is due to refusing the notification of the person's number, or even if it is notified, it must be judged whether or not it is the number of a reliable party. was there.

From the viewpoint of protecting the privacy of the side receiving the incoming call, it does not respond to the incoming call whose caller number is not notified,
In addition, even if the caller ID is notified,
It is advisable not to answer unless you are certain that it is a call from a trusted party.

Further, in the above-mentioned conventional telephone device, when the caller number information signal is not normally received, a normal incoming call is made, that is, when the caller number cannot be confirmed, the call is transferred to the incoming call format. Resulting in. In addition, since it does not ring for incoming calls, it has the following drawbacks.

(1) It is not possible to avoid the original purpose of answering an incoming call to a nuisance call.

(2) There is a possibility that no ringing will occur for a necessary incoming call, and important requirements and business opportunities will be lost.

As described above, there is a problem in that the function does not work properly and a highly reliable telephone device cannot be provided.

The present invention has been made in view of the above-mentioned problems of the above-mentioned prior art. The first object of the present invention is to make a call from a credible party. It is intended to provide a communication device which can perform a normal response operation only and can perform an automatic response in other cases.

A second object of the present invention is that even if an error occurs in receiving the caller number information signal,
An object of the present invention is to provide a communication device capable of accurately responding to a caller and appropriately responding to a malicious call.

Next, the operation of the communication apparatus according to this embodiment having the above configuration will be described with reference to FIGS. 4 to 6 and FIG. FIG. 7 is a flowchart showing the operation of the communication device according to this embodiment.

First, when an incoming call is received from the outside lines 407-1 to 407-n, the outside line interface 401 notifies the central control unit 403 via the control bus 409 that the incoming call is detected. The central control unit 403 determines in step S701 whether there is an incoming call from the outside lines 407-1 to 407-n until there is an incoming call. And the outside line interface 4
If it is determined from the notification received from 01 that there is an incoming call, the switching unit 402 is instructed to connect the communication path 408 and the communication path 413 via the control bus 409. When the connection between the call path 408 and the call path 413 is completed, the caller number information signal coming from the outside lines 407-1 to 407-n is transmitted via the outside line interface 401, the call path 408, the exchange section 402, and the call path 413. It is received by the ID detection unit 405. The received caller ID information signal is codec 5
00 to convert to digital / analog signal and modem 50
2 is input.

As the caller number information signal sent in the case of the caller number notification service provided by NTT, a modem signal conforming to the V22 standard is sent, but in the case of other methods, it is received. The same operation can be performed by changing the receiving system of the modem or the like.

When the modem 502 receives the modem signal, the modem signal is converted into a digital signal, and the sub controller 5 is connected via the signal line 503.
Send to 04. Next, the central control unit 403 determines whether or not the ID is detected in step S702. When the modem signal is normally received, the sub control unit 504 sends the ID to the control bus 4
When notifying the central control unit 403 via 09, the central control unit 403 determines that the ID has been detected. Then, the central control unit 403 starts the processing of the normal incoming call in step S703, and then ends this processing operation.

On the other hand, the modem signal is abnormal, for example, the outside line 4
When the reception signals of 07-1 to 407-n are below the minimum reception level, or when the modem signal cannot be normally received due to a failure such as disconnection of the line, the sub control unit 504 determines that the ID Is not detected, that is, it is determined that an error has occurred. Then, the sub control unit 504 causes the control bus 40
The central control unit 403 is notified of the occurrence of an error via 9.
Then, in step S702, the sub-control unit 504
When an error is detected by the notification from the central control unit 403
Controls the exchange unit 402 via the control bus 409 in step S704 to connect and exchange the communication path 408 and the communication path 414 and connect the recording / reproducing unit 406.

Next, the central controller 403 controls the control bus 409.
The sub-control unit 610 is instructed to send a response message via. When receiving the command, the sub control unit 61
0 controls the switch 602 in step S705,
The signal line 601 and the signal line 605 are connected, the response message sending unit 606 is connected to the codec 600, and the response message sending unit 606 is activated. As a result, a predetermined voice message is sent to the outside line partner via the codec 600 to notify that the requirement will be recorded. Then, in step S706, sub control unit 610 determines whether or not the outside party is disconnected. If the other party of the outside line does not disconnect the line, the sub-control unit 610 connects the recording unit 604 to the codec 600 and activates the recording unit 604 in step S707.

Next, in step S708, the sub control unit 610 is executed.
Judges whether or not the recording of the voice is ended by the disconnection of the line or the time-out, and when it is ended, the step S70 is executed.
At 9 the central control unit 403 performs line release processing,
This processing operation ends.

On the other hand, when it is determined in step S706 that the partner of the outside line is disconnected, the steps S707 and S708 are skipped and the process proceeds to step S709.

[0056]

As described above in detail, according to the communication device of the present invention, the normal response operation is performed only when it is convinced that the call is from the reliable communication partner, and in the other cases, the automatic response is performed. Therefore, it is possible to enhance the privacy of the called party without performing complicated operations.

Further, according to the communication end device of the present invention, even if an error occurs in the reception of the caller number information signal, it is possible to accurately respond to the caller, and also to a malicious call. Since appropriate measures can be taken, the device functions can be improved and the reliability is high.
