  However, in the telephone device described in Patent Document 1, no consideration is given to an increase in the number of other parties, so that an incoming call from the other party whose operator has forgotten to register the caller's telephone number automatically makes a call. There is a risk that the caller will be blocked and there is no way to contact the caller.

  Accordingly, the present invention provides an easy-to-use nuisance call prevention device that can easily register a number for identifying a call partner even if the number of close call partners that an operator becomes a caller and communicates with increases. The purpose is to provide.

  The present invention relates to a nuisance call prevention device connected to a line network, a storage means for storing a destination identification number capable of specifying a party to communicate with via the line network, and a call to the line network. Sometimes, a destination identification number indicating a destination is stored in the storage means as a destination identification number, and when receiving from the line network, the destination identification number stored in the storage means is notified from the line network. And a control means for comparing the caller identification number indicating the caller and permitting a call when they match.

  According to the present invention, the destination identification number of the destination is stored in the storage means as the destination identification number by the control means, and the destination identification number stored in the storage means when receiving from the line network, A caller identification number indicating the caller notified from the network is compared, and if they match, the call is permitted. Therefore, since the destination identification number indicating the destination is registered only by making a call, there is no registration omission.

Preferably, the control means deletes the designated destination identification number from the storage means when a special number dial indicating deletion of the designated destination identification number is input.
The special number dial can be used to indicate deletion of the recipient identification number, so if you make a mistake in the call destination or make a call once and you do not want to receive calls in the future, you can easily reject the call. it can.

When a special number dial indicating permission or disapproval of a call from a public telephone is input, the control means sets the public telephone permission information in the storage means, and receives an incoming call from the public telephone according to the public telephone permission information. It is desirable to determine permission or disapproval.
It is impossible to specify from which public telephone the incoming call comes from the notification of the caller identification number from the line network. Therefore, by allowing incoming calls from public telephones to be set using a special number dial, permission is set when there is a possibility of incoming calls from public telephones, and is not set when there is no possibility of incoming calls from public telephones. By setting the permission, it is possible to make a setting according to the usage environment of each operator, so that it is possible to provide a more convenient annoying call prevention device.

  In the nuisance call prevention device of the present invention, since a destination identification number indicating a destination is registered only by making a call, there is no registration omission, so that an operator can be in contact as a caller. Even if the number of close callers increases, a number for identifying the caller can be easily registered. Therefore, the nuisance call prevention device of the present invention is convenient.

FIG. 2 is a block diagram showing the configuration of the telephone adapter shown in FIG. In FIG. 1, a relay station and a base station that communicate with the mobile phone are omitted.

As shown in FIG. 1, a telephone adapter 1 is connected between a PSTN (Public Switched Telephone Networks), which is an example of a line network, and a telephone 2, and another telephone 3 (a fixed telephone or a portable telephone). This prevents annoying calls from the telephone).
As shown in FIG. 2, the telephone adapter 1 includes a line communication unit 11, a storage unit 12, a display unit 13, and a control unit 14.

The line communication unit 11 is a line interface having a function of notifying the control unit 14 of incoming calls from the PSTN and outgoing calls from the telephone 2.
The storage unit 12 is a non-volatile memory that can be read and written by the control unit 14. The storage means 12 is preferably, for example, an EEPROM (Electrically Erasable and Programmable Read Only Memory) because it is small and inexpensive and does not require a battery, but may be a battery backup memory. The storage means 12 stores various settings including the telephone number (partner identification number) of the other party whose incoming call is permitted and public telephone permission information. In this embodiment, an EEPROM capable of storing 400 telephone numbers is used.
The display unit 13 is a liquid crystal display panel that displays display data from the control unit 14. In the present embodiment, a character type of 20 characters × 2 lines is used.

  The control means 14 stores the telephone number of the destination (calling destination identification number) in the storage means 12 when making a call to the PSTN, or the telephone number stored in the storage means 12 and the PSTN from the PSTN when receiving a call from the PSTN. It has a function of comparing the notified caller telephone number (source identification number) and permitting a call when they match. Further, when a special number dial is input from the telephone 2, the control means 13 performs control according to the special number dial. Further, the control unit 14 has a function of reading a telephone number from the storage unit 12 and writing a telephone number in the storage unit 12 in accordance with a download signal or an upload signal from the line communication unit 11. Further, the control means 14 notifies the telephone set 2 from the PSTN depending on whether or not the function of displaying the caller telephone number (number display (registered trademark)) is provided in the telephone set 2 to be connected. A function for controlling information (MODEM signal) indicating a caller telephone number to be transmitted is provided.

  The operation and use state of the telephone adapter according to the embodiment of the present invention configured as described above will be described with reference to the drawings. FIG. 3 is a diagram for explaining connection when writing and reading a telephone number, (A) is a diagram showing a connection when a PSTN is interposed, and (B) is a pseudo switch It is a figure which shows the connection at the time. FIG. 4 is a diagram illustrating an example of a message when setting the presence / absence of a function for displaying a caller telephone number. FIG. 5A to FIG. 5C and FIG. 6 are diagrams showing examples of messages displayed on the display unit 13 when deleting the telephone number registered in the storage unit 12. FIG. 7 is a diagram showing an example of a message displayed on the display means when registering a telephone number permitted for incoming calls. FIG. 8 is a diagram showing an example of a message displayed on the display means 13 when setting whether to accept an incoming call from a public telephone.

  First, before use, a telephone number that permits incoming calls is registered in the storage means 12 of the telephone adapter 1. This registration may be directly written or may be written by downloading from a personal computer.

As shown in FIG. 3A, when writing and reading a telephone number from a personal computer (hereinafter referred to as a PC) 4 via the PSTN, the PC 4 is connected to a modem 5 connected to the PSTN. By performing writing by uploading from the PC 4 to the telephone adapter 1 via the PSTN and reading by downloading, the telephone number can be easily set or confirmed from a remote location.
Further, as shown in FIG. 3B, the telephone number can be written and read from the PC 4 via the pseudo exchange 6 instead of the PSTN, so that it can be written and read in the factory.

  In the PC 4, an application for uploading / downloading is operated. In the case of uploading, the PC 4 outputs the telephone number of the other party to whom the incoming call is permitted along with the upload signal. In the telephone adapter 1, the telephone number received by the control means 14 that has received the upload signal is written in the storage means 12. Thus, the setting of the telephone number can be completed at once.

  In the case of downloading, when the PC 4 outputs a download signal, the control means 14 reads out the telephone number of the other party whose call is permitted from the storage means 12 and transmits it to the PC 4. The PC 4 displays a list of received telephone numbers. Thus, by reading out the telephone number registered in the telephone adapter 1 and displaying it on the PC 4 side, the telephone number can be confirmed at a time.

  When registration is completed, the telephone adapter 1 is installed at the operator's home. When the telephone adapter 1 is installed, the telephone adapter 1 is connected between the PSTN and the telephone 2 as shown in FIG.

When the telephone adapter 1 is installed, first, the presence / absence of a number display function indicating whether or not the telephone 2 is provided with a function for displaying a caller telephone number is set. In this setting, the telephone 2 is off-hooked, and the “*” button indicating the special number of the telephone 2 and “0” and “0” are successively pressed. When the control means 14 recognizes that the special number dial has been pressed, it displays a message as shown in FIG. The operator who sees the display of “FIG. 1 = 1 = N = 2” presses the “1” button if the telephone 2 has the number display function. If the telephone 2 has no number display function, the “2” button is pressed.
The control means 14 disables the number display reception function if the button is “1”, and enables the number display reception function if the button is “2”. This setting is stored in the storage means 12.
When the number display reception function is invalid, the MODEM signal for notifying information and the like is monitored as the operation when the incoming call is received, the caller telephone number is displayed on the display means 13, and the MODEM signal is displayed on the telephone 2. Output to. That is, the telephone 2 side responds to the MODEM signal.
When the number display reception function is valid, a response to the MODEM signal is made as an operation when an incoming call is received, and the caller telephone number is displayed on the display means 13.

  The number display function cannot be used when two telephones connected to the PSTN are connected. However, in the telephone adapter 1 according to the present embodiment, when there is a function of displaying the caller telephone number on the telephone 2 side, only the MODEM signal is monitored and no response is made to the MODEM signal, thereby making a call to the display means 13. The telephone number can be displayed on the telephone 2 side as well.

  The control means 14 that has detected an incoming call from another telephone 3 searches the telephone number registered in the storage means 12 based on the caller telephone number from the PSTN. If this caller telephone number matches the telephone number stored in the storage means 12, it can be said that the caller is a relative or an acquaintance, and therefore the incoming call may be permitted. Accordingly, the control unit 14 performs an incoming call operation on the telephone 2.

  Further, if the caller telephone number does not match the telephone number stored in the storage means 12, it can be said that the caller is an unknown person, so the incoming call may be rejected. Therefore, the control unit 14 does not perform an incoming call operation on the telephone 2. By not performing the incoming call operation, the telephone 2 has no notification to the operator such as notification of incoming calls, so the operator does not notice the incoming call. Therefore, the operator is not concerned about annoying calls. Further, when the incoming call is rejected when the control means 14 rejects the incoming call, the incoming call operation is not performed, so that the caller side is not charged. Therefore, it may occur because the caller side is charged. The occurrence of troubles can be prevented.

  Next, a case where the operator makes a call will be described. The control unit 14 that has detected the transmission from the telephone 2 searches the storage unit 12 based on the telephone number (destination identification number) of the transmission destination from the telephone 2. As a result of the search, if it is determined that the telephone number is unregistered, duplicate registration is not performed. Therefore, the control unit 14 makes a new call-permitted telephone number (party identification number) along with the outgoing call operation to the PSTN. Is stored in the storage means 12. As described above, the destination telephone number is stored in the storage unit 12 as the telephone number that is the subject of call permission, so that the telephone number indicating the destination can be registered just by making a call.

  Therefore, there is no registration omission of the phone number that you want to allow, so even if the number of close callers that the operator becomes a caller and keeps in touch with you increases, you can easily register a number that identifies the caller can do. Therefore, the telephone adapter 1 can be used conveniently.

  Next, how to deal with an accidental telephone call will be described with reference to FIGS. When a wrong call is made, the telephone number of the other party is registered in the storage means 12 as a telephone number for which incoming calls are permitted. For example, there is a possibility that a telephone number is known because a wrong person is called, and an unwanted call is made from the malicious person. In this case, an operation for deleting the registered telephone number from the storage means 12 is performed. There are two types of this operation.

  First, the “*” button indicating the special number of the telephone 2 and “7” and “7” are successively pressed. When the control means 14 recognizes that the special number dial has been pressed, it displays a message as shown in FIG. The operator who sees the display of “Shortage of Power Save” presses the “#” button indicating that the input of the telephone number to be deleted and the telephone number has been completed.

  The control unit 14 searches the storage unit 12 based on the input telephone number. If the input telephone number is not registered in the storage means 12 as a result of the search, a message shown in FIG. 5B is displayed. If the input telephone number is registered in the storage means 12, the message and telephone number shown in FIG. 5C are displayed. If the displayed telephone number is correct, the operator presses the “1” button. If an incorrect entry is made, the “2” button is pressed.

  When the “1” button is pressed, the control unit 14 deletes the corresponding telephone number from the storage unit 12. In this way, when it is desired to delete a telephone number from which incoming calls are permitted, the registration can be easily deleted using a special number dial. Therefore, if the destination is wrong or if the user makes a call after making a call but does not want to receive a call in the future, the incoming call can be easily rejected.

  When the deletion of the telephone number is completed, the control means 14 displays the message of FIG. 5A again and waits for the input of the next telephone number. When the telephone number is subsequently deleted, the operator inputs the telephone number. When the deletion of the telephone number is completed, the operator on-hooks the handset. When the control means 14 detects an on-hook, the display is erased and the normal operation returns.

  Another method for deleting the telephone number registered in the storage means 12 will be described. First, the “*” button indicating the special number of the telephone 2 and “7” and “8” are successively pressed. When the control means 14 recognizes that the special number dial has been pressed, it displays a message as shown in FIG. When it is desired to pass the telephone number displayed on the display means 13 and display the next telephone number, the “1” button is pressed. To redisplay the previous telephone number, the “2” button is pressed. To delete the displayed telephone number, the “3” button is pressed.

If the “1” button is pressed, the control means 14 reads the next telephone number from the storage means 12 and displays it on the display means 13. If the “2” button is pressed, the control means 14 reads the previous telephone number from the storage means 12 and displays it on the display means 13. If the “3” button is pressed, the control means 14 deletes the telephone number displayed from the storage means 12 and reads and displays the next telephone number.
The operator goes on-hook when the deletion is complete. When detecting the on-hook, the control means 14 erases the display and returns to the normal operation. In this method, since the telephone number is displayed first, it can be used even when the telephone number registered in the storage means 12 is to be confirmed.

Next, a method for registering a telephone number will be described with reference to FIG. This is registered in advance when a call is not made to the telephone number but an incoming call from the telephone number is desired.
First, the “*” button indicating the special number of the telephone 2 and “9” and “9” are successively pressed. When the control means 14 recognizes that the special number dial has been pressed, it displays a message as shown in FIG. The operator who sees the display of “Kyokasludenwabango-yoku-ku-taku-taku-sai” presses the “#” button indicating that the entry of the telephone number to be registered and the telephone number has been completed.

  The control means 14 stores the inputted telephone number in the storage means 12 and displays a message shown in FIG. Since the registration can be easily performed in this way, the telephone number to be permitted to receive can be registered by an operation without making a call for registration.

Next, setting for incoming calls from public telephones will be described with reference to FIG.
First, the “*” button indicating the special number of the telephone 2 and “0” and “1” are successively pressed. When the control means 14 recognizes that the special number dial has been pressed, it displays a message as shown in FIG. The operator who sees the display of “Koji Shudenwa Kyoka = 1 Fuka = 2” presses the “1” button when he / she wants to allow the incoming call from the public telephone. If you want to refuse, press the "2" button.

  When the control unit 14 detects that the “1” button has been pressed, the control unit 14 sets the setting for permitting the incoming call from the public telephone, and if it detects the pressing of the “2” button, sets the setting for disapproving the incoming call from the public telephone. It is registered in the storage means 12 as telephone permission information. This is because it is impossible to specify from which public telephone the incoming call is based on the notification of the caller telephone number from the PSTN. Therefore, by setting whether to accept incoming calls from the public telephone, it is possible to perform settings according to the usage environment of each operator, and thus the telephone adapter 1 can be further improved in usability.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment. In the present embodiment, PSTN has been described as an example of the line network. Therefore, the destination identification number, the destination identification number, and the source identification number that can specify the other party to call are telephone numbers. For example, if the line network is a network such as the Internet used by an IP telephone or the like, these identification numbers can be an IP address or a MAC (Media Access Control) in addition to the telephone number.

In the present embodiment, the nuisance call prevention device is a telephone adapter connected between the PSTN and the telephone 2, but may be mounted in the telephone 2. However, since it can be installed in an additional form on the telephone 2 that has already been purchased and installed, the nuisance call prevention device of the present invention is a telephone adapter 1 that can easily take measures against nuisance calls. Is desirable.
Furthermore, since the special number dial used in this embodiment is an example, there is no problem even if another number is used as long as the function can be specified.

  The nuisance call prevention device of the present invention is suitable for preventing nuisance calls such as sales calls and obscene calls in addition to wire fraud.
