Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nuisance call prevention system, and an incoming call provided by an exchange operation company in order to protect a subscriber on the receiving side who is in a difficult position due to an incoming malicious call from a switched network from a damaged environment. The present invention relates to an additional subscriber service system supporting subscribers.

[0002]

2. Description of the Related Art Conventionally, when a called party receives a malicious call, the called party judges whether the call is malicious or not and then disconnects the call. 16
It is judged whether or not the called subscriber connects the incoming call with a telephone having a recording function such as an answering machine and reproduces the recorded contents later so that the called subscriber has malicious intent, like the switching device described in Japanese Patent No. 6954. For calls that were not malicious, the called party had to call back the caller. In addition, public skill number 92-
15028 When a malicious call arrives as described in "Unwanted call protection", the caller identification information of the malicious call is searched, and the corresponding person is registered as the malicious call sender. Calls coming from the caller do not connect to the callee, but the effect is not effective if the caller makes a call by changing the calling phone, which is the calling place, or when using a public or shared phone. I couldn't do it. It has been difficult for the called party to take effective measures for self-defense against malicious calls by placing the called party in an inconvenient environment that requires labor and time.

[0003]

The conventional means for defending the called subscriber against malicious calls is to receive the incoming call indirectly through a telephone with a recording function or to judge the presence or absence of the malicious call. All incoming calls, such as those that do not answer the call at all, are regarded as malicious calls and the called subscriber is protected from malicious calls. Also, even if the caller identification information is found at the exchange operator, the caller's position is given priority and cannot be transmitted to the called party, or the caller identification information is a subscriber terminal represented by a telephone that subscribes to the telephone service. It is difficult to identify the sender who is making the malicious call because the subscriber information depends on the.

[0004]

The nuisance call prevention system of the present invention includes a means for registering information on a subscriber who receives a service and a service target period, a means for searching the calling subscriber information of an incoming call, and an incoming call. Means for accumulating voice from malicious calls of
A subscriber who records the occurrence information of an incoming call, a means that informs the incoming call that a nuisance call prevention service is being implemented, a means that terminates the service that has been implemented, and a subscriber who grasps and manages the status of the service. Means for providing information to.

The present invention will be described below with reference to the drawings. FIG. 1 is a connection diagram showing an embodiment of the present invention.
FIG. 3 is a functional block diagram showing an embodiment of the present invention. Figure 1
At, the caller makes a call using the calling telephone 1. The originating exchange 2 makes a connection request for the originating call to the destination telephone 8 under the destination exchange 4 via the public network 3. The called exchange 4 rings the bell of the called telephone 8,
The called party answers. The callee judges that the received call is malicious and requests the telephone operation company to provide the nuisance call service. The operation of the telephone operation company inputs the subscriber information including the subscriber number of the nuisance call service requester, the service application period, the output means, and the malicious call countermeasure from the operation terminal 18.
The entered subscriber information is received by the service registration unit 28 of the nuisance call processing unit 21 of FIG.
Be registered with. The service is started after registering the subscriber information.

If the callee is judged to be a malicious call among the calls received by the callee telephone set 8 thereafter, the callee requests a caller search. The terminating exchange 4 receives the call connection request from the subscriber in the local station, and then the application service unit 2
4 confirms from the magnetic disk 16 whether the called party is a nuisance call prevention service registrant. If the user is a registrant, the nuisance call processing unit 21 is activated. Junk call processing unit 2
1 is a service control unit 27, a service registration unit 28, a caller search unit 29, a malicious call registration unit 30, a malicious call management unit 31,
The service canceling unit 32 is included. When the called party of the receiving side telephone 8 ringing the bell answers, the call connecting section 23 connects the calling party using the calling side telephone 1 and the called party using the receiving side telephone 8 and the three-way trunk 11 at the switch section 7 with a line. At the same time as the connection, the PB receiver 9 is connected.

[0007] The called party receives a call from the receiving-side telephone 8 while receiving a malicious call.
To generate a PB signal notifying a malicious call. The PB receiver 9 receives the PB signal, recognizes the signal of the malicious call confirmation from the callee, and informs the service control unit 27 of the signal. The service control unit 27 includes a sender search unit 29 that executes a sender search.
Then, the malicious call registration unit 30 for recording the voice situation of the malicious call is activated. The caller search unit 29 obtains the subscriber information of the caller telephone 1 which is an incoming call to the callee telephone 8 from the central control device 6 via the interoffice signaling network 5 in order to obtain the subscriber information.
The central control unit 33 of the above. When the called telephone 8 is an internal call, the central controller 6 obtains subscriber information within the local station. The caller search unit 29, which has obtained the subscriber number and station data of the caller telephone set 1 from the caller side exchange 2 as subscriber information, delivers the information to the malicious call management unit 31. on the other hand,
The malicious call registration unit 30 records the conversation of the connected call as voice data in the call storage device 14. When a caller is searched for a malicious call and a voice is recorded, the announcement device 12 can output a voice announcement of the malicious call prevention service to the incoming call side telephone 8 and the incoming call side telephone 1.

When the callee notifies the malicious call by PB signal and then disconnects the callee telephone 8 on-hook and disconnects, the service control unit 27 causes the callee telephone unit 8, the callee telephone set 1 and the three-way trunks via the call connection unit 23. The call path set between 11 is reset to the three-way trunk 11 and the receiving side telephone 1, the caller is searched and the voice is recorded. When the calling telephone 1 is on-hook, the call connection unit 23 disconnects the call path, and the malicious call management unit 31 causes the malicious call registration unit 30 to transfer the caller information passed from the caller search unit 29 to the call storage device 14. The date information and time information from the occurrence of the malicious call to the end are added to the index information of the recorded voice data and recorded on the magnetic disk 16.

During and after the termination of the malicious call prevention service, when the service registrant makes a request or at a predetermined registration date and time, the recorded voice data and the sender and date and time information indicating the occurrence of the malicious call are output. When the operator of the exchange inputs the data about the output method and the output time from the operation terminal 18 in response to the request from the service registrant, the sender and the date and time information recorded on the magnetic disk 16 indicating the occurrence of the malicious call are printed by the printer. From 17, the voice data retrieved from the call storage device 14 by the index information of the magnetic disk 16 is provided to the callee output to the cassette tape 15.

When the service registrant requests the service personnel of the telephone operating company to terminate the malicious call prevention service, the service personnel inputs the subscriber data of the service registrant from the operation terminal 18 to terminate the service. Was entered. The subscriber data is received by the service canceling unit 32 of FIG. 2 and is unregistered from the magnetic disk 16 and the call storage device 14.
