JPS5866456A - Informing system for outgoing number of malicious call - Google Patents

Abstract

PURPOSE:To ensure an automatic information about a malicious call number to a subscriber after the end of a call, by detecting the time and the malicious call number and storing them in a storage device when a malicious call retrieval request signal is received. CONSTITUTION:When a subscriber X transmits a malicious call retrieval request signal in response to the contents of a call, a central processor 4 adds the signal receiving time to the originating number stored in a buffer M and then stores them into a buffer N of a storage device 5. After the end of a call, the subscriber X hooks off a telephone 1 and then dials a prescribed number. Then the processor 4 transfers the contents of the information stored in the buffer N to an audio device 7 via a common bus 6 to inform the malicious call number.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for notifying a malicious call originating number by voice in response to a request from a subscriber who can receive a malicious call search service. In the malicious call detection service, a subscriber who can receive the service is hooked during an incoming call.
By making a specific dial, even if the caller goes on-hook, the call connection train is retained and the calling phone is reverse-detected, or the malicious call originating number is detected and displayed on the input/output device and typed out. I was trying to let him do it.

In either case, in order for the subscriber to know the malicious call origination number, the maintenance person at the exchange must be involved, and the subscriber also has to contact and have a meeting with the maintenance person. Such complications could not be avoided.

SUMMARY OF THE INVENTION An object of the present invention is to provide a malicious call originating number notification system that eliminates the drawbacks of the prior art described above and allows a subscriber to automatically receive notification of a malicious call originating number without bothering a maintenance person. It is in.

A feature of the present invention is that when a malicious search request signal is received from a telephone that can receive malicious call search service, the time and the malicious call origination number are detected, and these are stored in a storage device as malicious call information. and after the end of the notification,
In response to the transmission of a specific dial signal for requesting notification from the telephone, the telephone is connected to a voice device having a predetermined voice synthesis or voice editing function via a communication path network under the control of the central processing unit. , the malicious call originating number notification method is such that the malicious call information is transferred to the audio device, and based on this information, an audio signal with the malicious call originating number and time is generated and sent.

The purpose of including the generation time of the malicious call search request signal in the malicious call information is to generate and send an audio signal with the above generation time together with the malicious call origination number, and to send malicious calls to the subscriber. It is also intended to make it possible to confirm the time when a call is generated.

Hereinafter, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a relay system diagram of an embodiment of the malicious call calling number notification system according to the present invention, and FIG. 2 is a flowchart thereof.

2 is a telephone of subscriber Y that can make a malicious call; 3 is a communication network; 4 is a central processing unit; 5 is a storage device; 6 is a common device; 7 is an audio device.

First, when subscriber Y makes a call from telephone 2 and dials the telephone number of subscriber A call path A is established, and a connection is made between telephones 1 and 2 to enable an incoming call from subscriber Y to subscriber X (
In addition to block 10 in FIG. 7(a), the telephone number of the calling telephone 2 ( (calling number) is stored in the buffer M of the storage device 5 (block 11).

If the telephone 2 belongs to another station, the calling number can be obtained by sending a bank word signal requesting a calling number to that station.

Subscriber X sends a malicious call search request signal (
For example, when the central processing unit 4 monitors the above-mentioned request signal during the call, the central processing unit 4 checks the presence or absence of the above-mentioned request signal (block 12). If not, the call is terminated according to the end of the call, and if there is a signal, the calling number stored in the buffer M - the signal reception time (for example, the picking time) is added and stored in the buffer N of the storage device 5. After that, in block 13), the call termination process is performed in accordance with the end of the call. The accumulated content of this buffer N is
This becomes malicious call information that will be used for malicious call calling number notification and other purposes thereafter.

In addition, the buffer M of the calling number (block 11
) may be performed after receiving the malicious call search request signal.

Furthermore, the storage capacity of the buffer N may be limited to only one call in the latest past, or two or more calls within a predetermined period of time (for example, 24 hours) in the past, depending on the desired scale of the service or the spare capacity of the storage device 5. It may be about a call. In any case, as soon as the capacity of buffer N reaches its capacity limit, the accumulated content of buffer N will be
It will be replaced with the latest content.

Next, after completing the call with subscriber Y, subscriber
When the telephone 1 goes off-hook and dials a predetermined number (so-called special number call) (block 20 in FIG. 2(b)), the central processing unit 4 detects this and calls the telephone 1.
．．゛Setting the communication path network 30 communication path B between the audio devices 7 (
Same block 21).

Next, the storage device 50 checks whether there is accumulated information in the buffer N related to the telephone 1 (block 2
2).

If there is information stored in the buffer N, the contents (malicious call information) are transferred to the audio device 7 via the common bus 6, and the malicious call origination number is notified (block 23).

That is, the audio device 7 first sends a pre-prepared fixed advance notice announcement audio signal (for example, "The calling number of the current call") to the telephone 1 using known voice synthesis or voice editing.

The times are as follows: ''), and then, based on the above malicious call information, a synthesized (7 edited) voice signal of the calling number 1 time (for example, ``2, san, shi,'')
, Go, Roku, Shichi, Hachi (234-5678), Ichi.
2 Sankyuu (12:39)" was sent out. If there are multiple calling numbers, they are sent in the order of occurrence.

If there is no stored information in the buffer N, an instruction to that effect is given (block 24), and the audio device 7 outputs a pre-prepared fixed-form announcement audio signal (for example,
``There is no corresponding calling number.'') is sent.

As mentioned above, the audio device 7 has at least the following as variable audio:
It is only necessary to be able to generate 10 kinds of numeric sounds from "rei" (0) to "kyu" (9), so it is extremely simple and inexpensive and can be put to practical use.

As explained in detail above, according to the present invention, it is possible to notify the malicious call origination number only by the subscriber's operation without any communication with the station, thereby improving the service quality for the subscriber. A remarkable effect can be obtained in improving the performance and reducing the burden on maintenance personnel.
