DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a malicious call recognition exchange for recognizing a malicious call and taking some countermeasures.

[0002]

2. Description of the Related Art Telephones are widely used as simple communication means. However, malicious calls that exploit this simplicity are partially made, causing pain to telephone users. Here, the malicious call refers to a call from a caller that the called party does not want to talk to. Commonly known malices include prank calls to women from strangers at night,
Even if you answer the call, you can listen to him without speaking
There are harassment telephones. Here, a general call from a caller who does not want to talk to the caller is treated as a malicious call, including aggressive sales calls that ignore the inconvenience of the callee.

[0003] With the spread of telephones, the number of people suffering from such malicious calls is increasing, and countermeasures are needed. In order to allow more users to enjoy the convenience of a telephone, it is important to prevent malicious calls.

In FIG. 15, reference numeral 91 denotes a telephone set used by a malicious caller. Reference numeral 92 denotes a telephone set used by a malicious callee. 93 is a telephone set 91 used by a malicious caller.
And an exchange for connecting the telephone 92 used by the malicious callee. The exchange 93 is generally composed of a plurality of exchanges (connected via a plurality of exchanges), but for simplicity of description, this exchange is represented by one exchange.

Referring to FIG. 15, an outline of a general telephone call will first be described, and then a malicious call will be described.

[0006] A general telephone call starts when a caller who desires a call uses the telephone 91 to make a call. The caller picks up the handset of the telephone 91 and dials a number designating the other party who wants to talk. Then, exchange 93 receives the dial sent from telephone 91, analyzes the received dial, specifies the called party that the caller desires to talk to, and sets the telephone set 9 of the called party.
Send a signal to call 2 When the called party picks up the telephone set of the telephone set 92 after receiving the call of the telephone set 92, the exchange 93 recognizes the call and connects the communication path connecting the telephone set 91 and the telephone set 92, thereby making a state in which a telephone call is possible. More than,
It is an outline of a general telephone call operation by a telephone.

Conventional exchanges do not have the function of recognizing malicious calls, and therefore provide a switching service equally when there is a call request, regardless of whether they have malicious intent. In addition, there is a duty of confidentiality of communication by telephone, and it is obliged to comply with even a telephone operator. Malicious callers can use these to abuse them under the veil of confidentiality of communications and force them to talk to those who do not wish to communicate from them, It causes pain.

As a method for preventing such malicious calls,
The following methods are considered and some of them have already been implemented.

Means for generating an unpleasant and loud repulsion sound from the called party's telephone to the malicious caller.

[0010] Means that are not disclosed to an unspecified majority, such as not placing a telephone number in a telephone directory. A means for requesting a caller to provide a password or a subscriber number in addition to a publicly available telephone number, so that a call can be made only when a correct password or a pre-registered subscriber number is presented.

Means for sending an automatic response and sending or disconnecting a predetermined message when it is determined that the caller does not receive a predetermined response after sending the message, as a malicious call.

Means for identifying a malicious caller by the power of a public organization such as a telephone management company or police and imposing social sanctions.

[0013]

Although such a method can provide a certain effect to prevent malicious calls, it has the following disadvantages.

In the case of the above-mentioned repulsive sound from the called party side, the caller is surprised at the initial stage, and a certain effect is obtained, but the effect cannot be expected for the persistent malicious caller.

When the telephone number is kept secret, the telephone number is hidden even for a person who should not be kept secret, thereby sacrificing the convenience of the telephone. Also, due to the nature of telephone numbers being used by multiple people, it is unavoidable that they will eventually leak.

The above method of requesting the presentation of a password or the like requires a general good telephone user to also present a password or the like. If the password or the like is not known, it is treated in the same line as the malicious caller. , Will reject the call,
Even people who should not be repelled will be repelled, and in this case also, the convenience of the telephone is sacrificed and smooth communication is impeded.

Even in the above automatic answering method, there is a trouble that a caller cannot call another party unless a caller performs a predetermined answering operation irrespective of whether it is a malicious call or not, which hinders the convenience of telephone. Further, if a malicious caller knows this method, the malicious call can no longer be prevented.

Further, even with the method by the above-mentioned public institution, the use procedure such as the necessity of objective proof that the other party is a malicious caller is cumbersome, and the response is exaggerated and general use is made. Does not fit.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has as its object to prevent a malicious call without impairing the convenience of a telephone.

For this purpose, first, it is necessary to provide a malicious call recognition system for distinguishing a malicious caller from a normal caller.

That is, in order to prevent a malicious call without impairing the convenience of the telephone, a malicious caller is accurately distinguished from other normal callers, and a malicious caller is identified. It is necessary to perform a malicious eradication action only for In addition, it is necessary to realize this distinction promptly and as little as possible.

Next, in order to abandon the continuation of the malicious call, it is necessary to execute effective malicious call rejection measures for the caller of the malicious call.

It is an object of the present invention to provide a malicious call recognizing means and a malicious call repelling means effective to solve the above-mentioned problems.

[0024]

First, means for recognizing a malicious call will be described with reference to FIG.

In this principle diagram, reference numeral 14 denotes a malicious call information registration unit for registering information on a caller of a malicious call, and reference numeral 12 denotes that when the call is a malicious call, it is determined by the called party that the call is a malicious call. A malicious call registration request operation unit 16 for making a registration request to the call information registration unit 14 compares the caller information of the call to the called party with the caller information registered in the malicious call information registration unit 14. And a malicious call determination unit that determines the call as a malicious call when both are the same.

In the present invention, the above configuration is realized in the telephone 1 or the exchange 3. When implemented by the exchange 3, as shown in the principle diagram of FIG. 2, further provided is a called party information registration unit 34 for registering called party information that does not wish to receive a malicious call, and the malicious call determination unit 16 When the caller has called the called party, the caller information during the call is the same as the caller information registered in the malicious call information registration unit 14, and When the called party information during the call is the same as the called party information registered in the called party information registration unit 34,
The calling from the calling party to the called party is determined to be a malicious call.

Here, the malicious caller information may be any information that can identify the caller, such as the telephone subscriber number of the caller. The same applies to called party information.

The information registered in the malicious call information registration section 14 and the called party information registration section 34 are held for a certain period. The certain period may be any method as long as the period can be specified, such as until a release operation is performed by the called party or until a period predetermined by a timer elapses.

The malicious call registration request operation section 12 refers to a dedicated button, a push button for calling, or a dial provided on the telephone 1, and includes a method of pressing the dedicated button, and a push button or dial for calling. Any method can be used as long as the request can be specified, such as a method of dialing a predetermined number. When the called party performs a deregistration operation of the malicious call information registration unit 14 or the called party information registration unit 34,
The same operation unit as the malicious call registration request operation unit 12 can be used.

In the exchange 3, the malicious call information registration unit 14
The registration with the called party information registration unit 34 is always performed in pairs.
Needless to say, the same memory can be used for the malicious call information registration unit 14 and the called party information registration unit 34.

The means for repelling a malicious call according to the present invention includes an automatic response for returning an automatic response to a call determined to be a malicious call by the malicious call determination unit 16 and automatically disconnecting the call unilaterally. The disconnecting unit 28 is provided, and a charging control unit 44 for controlling a charging operation for the caller is provided. The charging control unit 44 determines whether the malicious call is determined by the malicious call determination unit 16 to be a malicious call. For example, charging a harassment fee can be exemplified, but in addition, in the case of a malicious call, means for transferring the call to a specific telephone number (for example, police) is also conceivable.

FIG. 3 is a diagram for explaining the principle of the malicious call repelling means. In the figure, reference numeral 16 denotes a malicious call determination unit which recognizes whether the incoming call is a malicious call. Reference numeral 28 denotes an automatic response disconnecting unit which automatically responds to a malicious call and sends a message, and then disconnects automatically.

FIG. 4 is a diagram for explaining the principle of the malicious call repelling means. In the figure, reference numeral 16 denotes a malicious call determination unit, which recognizes whether the incoming call is a malicious call. Reference numeral 44 denotes a charging control unit, which charges a malicious caller a nuisance fee when a malicious call is recognized. The repulsion means may be combined.

[0034]

In FIG. 1, the calling party information of a malicious call is recognized by the exchange 3 based on the accommodation position of the telephone set 2 used by the caller and transmitted from the exchange 3 to the telephone set 1 used by the called party. In other words, in order to register in the malicious call information registration unit 14 in the telephone 1 of the present invention, it is a condition that the exchange 3 has a caller information transmission unit 26 that acquires caller information and sends it to the telephone 1. .

When a malicious call is received, the called party issues a malicious call registration instruction by operating the malicious call registration request operation unit 12 and registers the malicious caller information in the malicious call information registration unit 14. I do.

The malicious call judging section 16 compares the caller information of the call to the called party with the caller information recorded in the malicious call information registering section 14. The call is determined to be a malicious call, and the operation proceeds to a malicious call repulsion operation.

In FIG. 2, a malicious call registration request receiving unit 40 recognizes that a malicious call registration request is sent from the telephone set 1 of the called party. Thereby, the called party information and the calling party information of the calling party who is in a talking state with the called party are recorded in the called party information registering section 34 and the malicious call information registering section 14, respectively. Upon receiving a call request, the malicious call determination unit 16 registers the set of the caller information and the called party information in the caller information and called party information registration unit 34 registered in the malicious call information registration unit 14. The call request is recognized as a malicious call when there is a match, and the operation shifts to malicious call rejection.

In FIG. 3, when a call request arrives from the exchange 3, the malicious call determination unit 16 checks whether the call request is a malicious call, and if it is recognized as a malicious call, notifies the automatic answer disconnection unit 28 of the call. Upon receiving this notification, the automatic response disconnecting unit 28 automatically responds, and then automatically disconnects. In some cases, a voice prepared in advance is sent between the response and the disconnection.

In FIG. 4, when a call request is issued from the telephone set 2 of the caller, the malicious call determination unit 16 checks whether the call request is a malicious call, and if it is determined to be a malicious call, sends a malicious call to the charging control unit 44. Instructs to start operation for repulsion. The charging control unit 44 receives the instruction and charges the malicious caller a troublesome fee for the malicious call. In the case of a public telephone, the charging pulse interval is shortened to increase the charging speed. It is expected that there is little probability that a well-intentioned third party will use a public telephone that has issued a malicious call. Considering such a case, a warning message may be issued in the case of a malicious call from a public telephone .

[0040]

Embodiment <Embodiment 1> FIG. 5 is a diagram showing an embodiment of a telephone 1 according to the present invention. The telephone 1 of this embodiment is a so-called touch-tone telephone , and as shown in FIG .
It has a malicious call registration request operation unit 12, a malicious call information registration unit 14, a malicious call determination unit 16, and a malicious call rejection unit 18.

Here, the caller information receiving unit 10 receives the caller information sent from the exchange 3 every time a call is received. The malicious call registration request operation unit 12 uses a push button for dialing a telephone number. However, it is more convenient to provide a dedicated button. Malicious call information registration unit 1
Reference numeral 4 denotes a storage device for registering the caller information received by the caller information receiving unit 10 as malicious call information in response to an operation of the malicious call registration request operation unit 12. The malicious call determination unit 16 compares the caller information received by the caller information reception unit 10 with the caller information registered in the malicious call information registration unit 14, and if the two match, the incoming call is determined. It is determined to be a malicious call, and a request to start a malicious call repulsion operation is made. That is, a malicious call rejection request signal is sent to the malicious call rejection unit 18. The malicious call rejection unit 18 receives a malicious call rejection request signal transmitted from the malicious call determination unit 16 and starts a malicious call repulsion operation.

The malicious call information registration unit 14 can record a plurality of pieces of caller information as shown in FIG. As a result, the caller of the malicious call can be transmitted to a plurality of telephones 2 such as a public telephone.
Is used, the telephone 2 to be used can be successively registered as the telephone 2 used by the malicious caller.

On the other hand, the exchange 3 in which the telephone 1 is accommodated
Has a central processing unit 20 and a main storage device 22. The central processing unit 20 obtains the caller information based on the accommodation position of the telephone 2 used by the caller and obtains the main storage device 2
2 and a caller information transmitting section 26 for transmitting the caller information stored in the main storage device 22 to the telephone 1 used by the called party. The caller information is always sent to the telephone 1 of the called party regardless of whether the call is a malicious call.

Next, as shown in FIG. 7, the malicious call rejection unit 18 includes an automatic response disconnection unit 28 and a voice transmission unit 30. The automatic response disconnection unit 28 Upon receiving a malicious call-back operation start request, the system automatically responds to the request, requests the sound transmitting unit 30 to transmit a malicious call-back sound, and automatically disconnects after a predetermined time elapses by a timer (not shown). The voice transmitting unit 30 is composed of, for example, an IC card ROM or a micro cassette tape recorder, and transmits a prepared malicious call rejection voice based on a request from the automatic response cutting unit 28.

The malicious call repulsion according to the present embodiment will now be described with reference to FIG.
This will be described with reference to the flowchart of FIG.

First, as shown in FIG. 8, when there is a call from the caller (step 100), the caller information acquiring unit 24 of the exchange 3 uses the accommodation position of the telephone 2 of the caller as a clue. The caller information of the caller is obtained and stored in the main storage device 22 (step 101), and the caller information sending unit 2 is obtained.
6 sends the caller information stored in the main storage device 22 to the telephone 1 of the called party. At the same time, the caller information receiving unit 1
0 receives the caller information from the exchange 3 and temporarily stores it (step 102). Next, the called party is called by the exchange 3, and the called party picks up the handset and starts talking (step 103).

Here, if the called party recognizes that the call from the calling party is a malicious call based on the contents of the call, the calling party to the malicious call information registering section 14 is operated by operating the malicious call registration request operating section 12. An information registration request is issued (step 104). Then, the caller information held in the caller information receiving unit 10 of the telephone 1 is sent to the malicious call information registering unit 14 as malicious call information (step 105), and a predetermined address of the malicious call information registering unit 14 is stored. Is registered (step 106). Finally, the call between the calling party and the called party is terminated (step 107).

With the above, the malicious call information registration operation flow is completed. Thereafter, when the same caller calls the same called party using the same telephone 2 (step 110).
As shown in FIG. 9, first, the caller information obtaining unit 24 of the exchange 3
Obtains the caller information of the caller based on the accommodation position of the caller's telephone 2 (step 11).
1) The caller information is sent to the telephone 1 of the called party (step 112).

This caller information is stored in the caller information receiving section 10 (step 113). Next, the caller information receiver 10 sends the caller information and the caller information comparison command to the malicious call determiner 16 (step 114). Malicious call determination unit 1
6 reads the malicious call information from the malicious call information registration unit 14,
A comparison is made with caller information (step 115).

Here, it is determined whether or not the caller information is the same as the malicious call information (step 116). If the information is not the same, a normal call operation is started and a ringing tone is sounded (step 11).
7), the call path is selected by raising the handset, and a call state is established (step 118). When the call ends, the call path is cut off by lowering the handset (step 11).
9).

On the other hand, if the caller information is the same as the malicious call information, the fact that a malicious call has been detected is transmitted to the automatic response disconnection unit 28 of the malicious call rejection unit 18 (step 120). The automatic response disconnecting unit 28 automatically responds, and
A talk key transmission command is sent to 0 (step 121). Then, the voice sending unit 30 sends a talkie (step 12).
2) Automatically disconnect after a predetermined time has elapsed after the automatic response of the automatic response disconnecting unit 28 (step 123). <Embodiment 2> This embodiment is an example in which the malicious call rejecting unit 18 is provided in the exchange 3 instead of being provided in the telephone 1 in the embodiment 1. In addition, a talkie trunk is provided in the exchange 3 as the voice transmission unit 30. In this case, the malicious call determination unit 16 sends a malicious call rejection request signal to the malicious call rejection unit 18 of the exchange 3, and a malicious call rejection message is sent from the talkie trunk to the caller. The other parts are the same as those in the first embodiment, and a description thereof will be omitted. <Embodiment 3> Next, an embodiment in which the present invention is embodied in the exchange 3 will be described with reference to the drawings.

The exchange 3 has a central processing unit 20, a main storage device 22, and an external storage device 32. A malicious call information registration unit 14 for registering malicious caller information in the external storage device 32, a callee information registration unit 34 for registering callee information not wishing to receive a malicious call, A charging meter 36 for recording the telephone usage fee for each user is provided.

Also, the central processing unit 20 obtains the caller information based on the accommodation position of the telephone 2 used by the caller, and temporarily stores the caller information in the main storage device 22. 24, a called party information acquiring unit 38 for acquiring the called party information based on a dial sent from the calling party and temporarily storing the information in the main storage device 22, and a malicious call registration request from the called party. A malicious call registration request receiving unit 40 for receiving a call, a malicious call determining unit 16 for determining whether or not the call to the called party is a malicious call, and a call connection control based on the determination result of the malicious call determining unit 16. And a charging control unit 44 for controlling charging of a charging meter corresponding to the caller.

The malicious call judging section 16 is a caller information acquiring section 2
4 and the set of called party information acquired by the called party information acquiring unit 38 are compared with the set of malicious call information registered in the malicious call information registering unit 14. It is determined that the call is a malicious call, and the callee information obtaining unit 38 is notified of that fact.

The malicious call information registering section 14 and the called party information registering section 34 are composed of substantially the same memory, and the calling party information of the malicious call and the called party information are paired as shown in FIG. sign up.

The subscriber connection control unit 42 controls the connection between the calling party and the called party, simultaneously monitors the occurrence of various requests from the calling party and the called party, and sends a malicious call registration request from the called party. If there is, the malicious call registration request receiving unit 40 is notified to that effect. Upon receiving the notification, the malicious call registration request receiving unit 40 instructs the malicious call information registration unit 14 to register malicious call information.

The subscriber connection control unit 42 sends malicious call recognition information to the charging control unit 44 to instruct the start and end of charging. The billing control unit 44 adds and collects a predetermined inconvenience fee in addition to the normal call charge to the billing meter 36 of the malicious caller, and collects the billing meter 36 of the malicious callee.
In addition, a fee is charged in the form of paying a nuisance fee. If the caller uses a telephone 2 such as a public telephone that does not have the charging meter 36, the caller is added to the charging meter 36 by, for example, shortening the time interval of the charging pulse sent to the telephone 2. Is controlled to achieve the same effect as.

Next, the telephone 1 accommodated in the exchange 3
Has a malicious call registration request operation unit 12 for issuing a malicious call registration request to the exchange 3 when the incoming call is a malicious call. This malicious call registration request operation unit 12 is similar to the first embodiment.
By a push button or a dedicated button for dialing a telephone number.

The malicious call repulsion according to the present embodiment will now be described with reference to FIG.
3, and will be described with reference to the flowchart of FIG.

First, as shown in FIG. 13, when there is a call from the caller (step 130), the caller information acquiring unit 24 of the exchange 3 uses the accommodation position of the telephone 2 of the caller as a clue. The caller information of the caller is obtained and temporarily stored in the main storage device 22 (step 131). On the other hand, the called party information acquisition unit 38 acquires the called party information of the called party based on the dial sent from the calling party, and temporarily stores the called party information in the main storage device 22 (step 132). . Then
The called party is called by the subscriber connection control unit 42, the called party picks up the handset, and the call starts (step 13).
3).

Here, when the called party recognizes that the call from the calling party is a malicious call based on the contents of the call (step 13).
4) A request for registering caller information to the malicious call information registration unit 14 is issued by operating the malicious call registration request operation unit 12. Then, the subscriber connection control unit 42 sends a malicious call information registration request to the malicious call registration request receiving unit 40 (step 135). And
The main storage device 2 is controlled by the malicious call registration request receiving unit 40.
2 is stored in the malicious call information registration unit 14
The called party information is registered in the called party
4 are registered so as to form a pair with each other (step 136). Finally, the call between the calling party and the called party is terminated (step 137).

Thus, the malicious call information registration operation flow is completed. Thereafter, as shown in FIG. 14, when the same caller uses the same telephone 2 to call the same called party ( Step 140) First, the caller information obtaining unit 2 of the exchange 3
4 acquires the caller information of the caller based on the accommodation position of the caller's telephone 2 and temporarily stores the caller information in the main storage device 22 (step 141). Next, the called party information acquisition unit 38 temporarily stores the called party information of the called party in the main storage device 22 to obtain the called party information based on the dial sent from the calling party (step 142), and The called party information acquisition unit 38 sends a malicious call comparison command to the malicious call determination unit 16 (step 144).

The malicious call judging unit 16 comprises the malicious call information registering unit 1
4, while reading out the called party information paired with the malicious calling information from the called party information registering section 34, the calling party information temporarily stored in the main storage device 22 and the called party information are read. The called party information is compared with "malicious call information" and "called party information rejecting a malicious call", and the result is referred to as called party information acquiring section 3.
8 (step 145).

As a result of this comparison, if the calling party information and the called party information do not match the malicious call information and the called party information that rejects the malicious call (step 146), a normal switching operation is performed. That is, the called party information acquisition unit 38 requests the subscriber connection control unit 42 to connect the calling party and the called party (step 147). Upon receiving this, the subscriber control unit connects the calling party and the called party, and requests the charging control unit 44 to start charging as a normal call (step 148). The charging control unit 44 charges the caller's charging meter 36 as a normal call (step 149).

On the other hand, if it is determined in step 146 that the caller information from the caller and the called party information are the same as the "malicious call information" and the "malicious call rejected callee information", The called party information acquisition unit 38 notifies the subscriber connection control unit 42 of the connection request of the calling party and that the call is a malicious call (step 15).
0). Then, the subscriber connection control unit 42 connects the calling party and the called party, and requests the charging control unit 44 to start charging as a malicious call (step 151). The charging control unit 44 charges the calling party's charging meter 36 for the malicious call, and charges the calling party's charging meter 36 by the amount obtained by subtracting the normal charging from the malicious call charging (step 152). .

After the above, when there is a disconnection request from the calling or called party, the subscriber connection control unit 42 detects the disconnection request, disconnects the communication path, and requests the charging control unit 44 to terminate charging. (Step 153). In response, the charging control unit 44 stops charging (step 154).

In the above case, although the probability is very small, a general user who uses a public telephone or the like may be treated as a malicious caller. To cope with this, also in the present embodiment, the voice transmission unit 30 is provided as in the first embodiment, a warning message is issued to the caller of the malicious call before the start of charging, and charging is started after a predetermined time elapses. Such a method can prevent a general telephone user from being charged for sending a malicious call.

[0068]

In order to prevent a malicious call, it is necessary to accurately and promptly recognize the malicious call, and to execute the repulsion method when the malicious call is recognized.

According to the present invention, when a malicious call is found, it is promptly and easily performed according to the intention of the victim, the victim of the malicious call. By pressing a malicious call registration request operation button provided on the telephone, for example), data for specifying the caller of the malicious call can be registered.

Therefore, after the second time, it is possible to automatically recognize a malicious call without bothering the called party.

Also, for example, even when a malicious caller uses a plurality of public telephones, by registering a plurality of malicious call information, it is possible to recognize a malicious call from those telephones and repel it. Can be.

On the other hand, even if such a malicious caller is present,
Not all calls from registered telephones are subject to regulation as malicious calls. In particular, in the exchange 3 of the present invention, a malicious call is recognized only when both the calling party information and the called party information match, so that the influence on a general telephone user can be suppressed to a negligible level.

Further, the malicious call recognition system according to the present invention does not cause any problem in respect of the observance of the confidentiality of communication. That is, whether the call is treated as a malicious call depends on the intention of the called party and does not require the intervention of a third party other than the party making the call, so that the confidentiality of the communication is observed.

[0074]

The charge repelling means according to the present invention is a malicious call repulsion method by economically giving a blow to a malicious caller. That is, this is a method of collecting a nuisance fee from a malicious caller. This makes it possible to economically impact the malicious caller and inform the user that the act of calling the malicious call is not economically viable.
