Abstract

PURPOSE:To register a telephone number such as a malicious call or the like with a simple operation during a busy state when a busy call is a malicious call or the like by providing a means connecting to an electronic exchange and storing a telephone number of a caller rejecting an incoming call by a called party for each called party. CONSTITUTION:The system is provided with a electronic exchange 1 to which a caller telephone number is informed from the caller and a subscriber information storage means 2 connecting to the electronic exchange 1 and storing the caller telephone number whose call is rejected by a called party for each called party. When a called party 4 in busy with a caller 3 discriminates it that the re-dialing from the caller 3 after the talking is to be restricted, the telephone number of the caller 3 is stored in the subscriber information storage means 2 by the operation of the telephone set of the called party 4 and an incoming call from the caller 3 to the called party 4 after the talking is restricted by referencing the subscriber information storage means 2. Thus, when a call is a malicious call or the like, the telephone number of the malicious call or the like is registered during talking with a simple operation.

Description

[Detailed Description of the Invention] [Summary] Regarding the call restriction connection method in electronic exchanges, especially the malicious call disconnection method, if the call being made during a call is a malicious call, the malicious call can be blocked by a simple operation during the call. For the purpose of making it possible to register the telephone number of a call, etc., the telephone number of the caller is connected to the electronic exchange where the telephone number is notified from the caller, and the electronic exchange. and a subscriber information storage means for storing the telephone number of the caller who refuses to receive the call, and the called party who is on the phone with the caller decides that he/she wants to restrict the caller from receiving a second call after the call. When the called party operates the phone on the called party's side, the calling party's telephone number is stored in the subscriber information storage means, and the subscriber information storage means stores the call from the calling party to the called party after the call. Configure to refer to and regulate.

[Industrial application field]

The present invention relates to a call restriction connection method in an electronic exchange in an I5DN switching network, and particularly to a malicious call disconnection method.

In the recent era of advanced communication, free communication has become possible, but on the other hand, the number of malicious calls has also increased rapidly, and the countermeasure method is L5DN.
It is required as a support for switching services in switched networks.

[Conventional technology]

As a conventional measure against malicious calls, a method is known in which the caller specifies a specific password. According to this method, the called party notifies in advance a specific password to a specific caller to whom the called party is permitted to receive the call, and this specific password is kept secret from a third party.

With this method, only those who know the specific password can make a call.

As another conventional method of countermeasures against malicious calls, there is a method that modifies the transmitted voice from the called party to give a vibrato effect, although this is not a connection rule.

[Problem to be solved by the invention]

However, in the former conventional method, the number of callers is limited and a third party who does not know the password cannot make a call, so there is a problem that it is no longer a form of free communication. Furthermore, before making a call, the called party has to take the trouble of registering in advance the caller who is permitted to receive the call, and there is also the problem that the procedure is complicated.

Furthermore, the latter conventional method simply changes the voice of the called party, and is not a definitive method for regulating incoming calls.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to enable, when a call is a malicious call, to register the telephone number of the malicious call or the like with a simple operation during a call.

[Means for solving problems]

FIG. 1 is a block diagram of the principle of the present invention. In the figure, 1 is an electronic exchange where the caller's telephone number is notified from the caller, 2 is connected to the electronic exchange 1, and each called party makes a call where the called party rejects the incoming call. This is a subscriber information storage means for storing the subscriber's telephone number. When the called party 4 who is on the phone with the calling party 3 decides that he or she wants to restrict calls from the calling party 3 after the call, the calling party
The telephone number of the subscriber information storage means 2 is stored in the subscriber information storage means, and the incoming call from the calling party 3 to the called party 4 after the call is regulated by referring to the subscriber information storage means 2.

[For production]

If a call is determined to be malicious during a call and it is determined that it is desired to restrict re-incoming calls from this malicious call, the caller's telephone number is registered in the subscriber information storage means 2 by operating a button on the telephone. As a result, even if the same malicious call is made to the same called party, the telephone number of the subscriber making the malicious call is registered in the subscriber information storage means, so the call is made to the called party. No connection is made.

〔Example〕

FIG. 2 is a block diagram illustrating a call restriction connection system according to an embodiment of the present invention. In the figure, 21 is an exchange network, 22 is a central processing unit (CPR), 23 is a main memory IJ (MM) that stores programs and data that control exchange operations, 24 is a file memory that stores subscriber information, and 25 26 and 27 are trunks connecting to adjacent stations, subscriber control circuits (LC) connecting subscriber terminals.
, 28 is an announcement machine, 29 is subscriber A's telephone, and 30 is subscriber B's telephone.

Figure 3 is the file memo shown in Figure 2! J(FM)24
FIG. 12 is a diagram showing the contents of , in which malicious call information is stored as subscriber information in addition to the subscriber's telephone number (ON). The malicious call information stores the telephone number of the malicious caller, its registration time, and its cancellation type information.

For example, if the telephone number of caller A is stored as malicious call information, by operating the called party's telephone, the telephone number of caller A is stored in the subscriber information storage means, and the call is made. File memo for subsequent calls from caller A to called party B! It is regulated with reference to J(FM)24.

FIG. 4 is a flowchart illustrating the operation of the central processing unit (CPR) 22 shown in FIG. In the same figure,
When a call is received from subscriber A's telephone 34 in step 401, in step 402 it is translated whether the called number is a trunk line, a subscriber line, a special number, etc.

As shown in step 403, the result of the translation is that if the called party 9 is dropped from the local station, the received telephone number is referred to the file memory 24 in step 404, and if it is not registered as malicious call information in the subscriber information, the process is executed in step 404. Proceeding to step 405, calling subscriber B speaks with subscriber A, and in step 406 subscriber B
If the subscriber A does not recognize the call as a malicious call, a normal call is made in step 407. If subscriber B recognizes subscriber A as a malicious call in step 406, the malicious call is registered in the file memory 24 in steps 409 to 413 within step 408. That is, in step 409, a special number + cancellation type number (for example, '#1 Toll') is dialed for newly implementing call restriction.Receiving this signal, the exchange receives a special number under the control of the special number receiving device. New data is registered in the subscriber information of caller B.

In addition, in order to let called party B know that the registration has been completed, the ANM sends a completion message to called party B.

The registered information deletion method refers to the cancellation type information and registration time in the subscriber information table to determine the information to be deleted, and periodically deletes the information.

Specifically, in step 409, a special number is sent by pressing a specific button on subscriber B's telephone 30, and in step 41
At step 0, the special number receiving device (not shown) in the central processing unit 22 confirms that the special number has been pressed, and in step 411, calls the calling subscriber A's telephone number from the calling number storage table (not shown) in the file memory 24. Extract subscriber A's telephone number.

Then, in step 412, the subscriber information table for subscriber B shown in FIG. 3 is modified using the telephone number of calling subscriber A extracted in step 411. This results in
The telephone number of subscriber A is registered as the calling party's telephone number in the subscriber information table of subscriber B, and the registered time is recorded as the registration time. Then, in step 413,
A registration completion sound is transmitted to the receiving subscriber.

In step 404, in the subscriber information table of subscriber B,
If there is malicious call restriction information, it is determined in step 414 whether the telephone number of the called subscriber A is registered.

If not registered, the process advances to step 405 and steps 406 to 413 described above are executed. If the telephone number of subscriber A is recorded in the subscriber information table of subscriber B as a malicious call in step 414, the line is connected to the announcement machine (ANM) 28 in step 415. Then, from step 416, the originating subscriber A is notified of some message.

Regarding the cancellation of registered malicious call information, subscriber B can dial the special number 10 cancellation type number to select the type that will be automatically deleted after a certain period of time or the type that will not be canceled semi-permanently. The format is selectable. For this purpose, the subscriber information table stores registration time and cancellation type information in addition to the calling party telephone number.

Therefore, the call disconnection state is maintained for a certain period of time, and it is possible to effectively deal with continuous harassing calls seen in malicious calls and harassing calls made periodically.

In the above embodiment, a method was explained in which the reception of subsequent malicious calls is restricted by registering a malicious call during a call. However, the present invention is not limited to this, and registering a malicious call during a call is not limited to this. Applicable to any convenient application.

〔Effect of the invention〕

As explained above, according to the present invention, a call from a specific subscriber can be registered as a malicious call etc. by a simple operation by the called party during a call, and subsequent reception of malicious calls can be restricted. This greatly contributes to the regulation of malicious calls, which is one of the negative aspects of the current advanced communication society.
