CONSTITUTION:When a telephone set 10a makes a call, a caller side talker operates dialing to receive dial information and a personal number of a designated reply party from a designation reply party identification code input means 16 in the telephone set 10a used by itself and sends them to an exchange 20. Thus, the exchange 20 sends a call to the telephone set 10b of a number dialed by the caller and sends the personal number. When the telephone set 10b receives a call, a comparison collation means 18 compares and collates the received personal number with a personal number of a designation reply party stored in an incoming reply party identification code registration storage means 17, and a switch circuit section 14 is closed when they are coincident to attain voice communication.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a telephone set that allows telephone calls only between designated parties.

(Prior Art) With conventional telephones, by operating a pushbutton, rotary dial, etc. provided on the telephone and dialing the number of the other party, it is possible to call the other party having that telephone number. In addition, when receiving a call, you can turn off the hook on the handset, or press a function button such as ``Speaker reception'' or ``Audible call'' on a multi-function telephone.
Anyone can easily answer all incoming calls. However, in the case of a telephone call that corresponds to a "confidential" letter, that is, if you want to talk to a designated person,
If the person you specify is not nearby, you will need to talk to the person who picked up the handset and have them call the desired person.

In addition, there are cases where you do not want others to know about an incoming call from a specific person, and in such cases, the person waiting for the call should make sure that others do not pick up the handset when the call arrives. You wait around the telephone, and when a call arrives, you must be the first to pick up the receiver.

(Problem to be solved by the invention) With conventional telephones, by dialing the number of the other party, it is possible to call the other party of that telephone number, and anyone can easily call the other party by picking up the handset when receiving a call. It is now possible to answer calls. However, on the other hand, there are many cases where you only want to talk to a person you specify, and you do not want anyone other than the person you specify to answer the phone. If you know that there will be a call, wait around the phone so that others do not pick up the handset, and when a call arrives, you will have to be the first to pick up the handset, and you will have to be the first to pick up the handset. In such cases, it may not be possible to prevent others from leaving.

As described above, conventional telephones have the problem that there is no regulation for answering incoming calls, and that it is not possible to specify the party to answer when making a call.

Therefore, the purpose of this invention is to have a specific person call function that allows only a specific person to talk to an incoming call.
To provide a telephone that allows confidential calls to be made with peace of mind.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. In other words, there is a means for transmitting a personal identification code when a call is made, a means for registering the personal identification code of a designated caller, and a means for checking the registered personal identification code when a personal identification code is received at the time of an incoming call, and checking whether the personal identification code matches the registered personal identification code. and a control means for permitting a telephone call only when a call is made.

(Function) In such a configuration, when it is desired to make a confidential telephone call, the personal transfer code transmitting means transmits a personal identification code (ID code) for identifying the other party on the other end at the time of making the call. When the called side receives an incoming call and receives an ID code, the control means reads out the registered ID code from the personal identification code registration means, compares it with the received ID code, and permits the call only when the ID code is accepted. control like this.

When a call is received, if no ID code is received, anyone who picks up the called phone can talk, just like a normal telephone.

In this way, this device registers an ID code, and when you want to make a confidential call, it uses an ID code to identify the other party.
A D code is sent, and when this ID code is sent, it is checked against the ID code registered in the called party's telephone, and a call is made possible only when the ID code matches. Therefore, if you are expecting a call from a specific party and the person who should receive the call is near the phone, you can register your own ID code on the phone and delete the registration when you leave the phone. It becomes possible to prevent a third party from receiving a call from a specific party when the user is absent, and only one person can receive a call from a party who does not want others to know.

Therefore, according to the present invention, it becomes possible to prevent a third party from receiving an incoming call from a specific party, and only one person can receive such a call from a party who does not want others to know. It is possible to provide a telephone that allows calls to be made with peace of mind.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of this device. As shown in the figure, a network connection means (1) such as a modem or an SDN interface, and an analog communication circuit section 13 to which a , a switch circuit section 14 that connects the analog communication circuit section 13 and the network connection means 11;
, and performs call control and uses a personal number (personal identification code;
a communication control means 15 for transmitting, receiving, and detecting a designated responder identification code (ID code); and a designated responder identification code manual means 16 for manually inputting a personal number of a designated responder to be sent to the called party when a call is made;
The incoming call answerer identification code registration storage means 17 registers and stores the personal number of the person answering the incoming call, and the personal number of the designated answerer received from the calling party is registered in the incoming call answerer identification code registration storage means 17. It is constructed using a comparison and verification means 18 that compares and verifies the personal number of the incoming call responder that is stored.

A telephone with such a configuration is connected to an exchange 20 via a line as shown in FIG. In the digital switching network, there is a service that notifies the telephone number of the calling party's telephone device.
This is a function in which a call setup message containing the information elements to be transmitted is sent to the network, and the network automatically adds the information element of the calling party's telephone number to the message and sends it to the called party's telephone equipment.
Use this feature.

When making a call from the telephone 10a, the calling party dials and inputs the dialing information and the personal number of the designated responder from the designated responder identification code input means 16 of the telephone 10a that he or she is using, and then calls the exchange. Send to 20. As a result, the exchange 20 allows the call to arrive at the telephone tab of the number dialed by the caller, and transmits the personal number.

When the telephone 10b receives a call, it checks whether or not a personal number has been received, and if a personal number has been received, it has been received as the designated responder's personal number stored in the incoming call responder identification code registration storage means 17. The comparison and verification means 18 compares and verifies the personal number. Then, as a result of comparison and verification, if there is a match, a match output is output from the comparison and verification means 18, which closes the switch circuit section 14 and enables voice communication.

Therefore, with this device, if you want to make a call only between specific parties and you do not want the call to be picked up by someone else, you can share your personal number with each other and place the phone near the phone of the called party. When there is a party involved, if that party registers his or her own personal number in the incoming call answerer identification code registration storage means 17, when the caller sends the personal number at the time of making a call, the call will be received by the other party. , it becomes possible to talk only between parties that have been agreed upon in advance, and it becomes possible to avoid the inconvenience of having someone pick up the phone because you are not around. In addition, if you temporarily leave your seat or are absent, please register your personal number on your telephone by registering the incoming call answerer identification code.
If you cancel your own personal number registration in step 7, even if the other party makes a call specifying the personal number,
Since the call cannot be made to the other party's phone, the inconvenience of having someone pick up your call can be avoided. If no personal number is received, the same control as for normal incoming calls is performed.

A more specific configuration of this device is shown in FIG.

The figure is a block diagram showing the detailed configuration of this telephone, which is connected to the basic interface of I5DN,
For example, an IC card (a card that uses an integrated circuit, has a large-capacity memory function, and can at least exchange data with the outside world), so that individuals can easily carry out secret calls with a specific person. to enter your personal number (I
D code) is registered and stored. In the figure, 30 is a home bus of the digital exchange network, and 31 is a receiving circuit, which receives digital signals from the home bus 30. 32 is a frame synchronization detection circuit (FSY
N), which detects frames from the digital signal received by the receiving circuit 31. 33 is a frame decomposition circuit (FADS) which decomposes and extracts each bit of each information channel (Bl, B2) and D channel from each received frame. 34 is a D channel control circuit, which detects each data, flag, and control signal in the D channel during reception, and forms a D channel frame during transmission. 35 is a frame assembling circuit which assembles a signal format from the input information channels (B1, B2) and D channel. 36 is a transmitting circuit, which transmits the frame-assembled data outputted from the frame assembling circuit 35 to the home bus 30.

Reference numeral 37 denotes a speech circuit section, which converts the signal given through the frame decomposition circuit 33 to D/A and supplies it to the receiver section of the handset 38 as an analog audio signal, and also converts the signal given from the transmitter section of the handset 38 into an audio signal. The signal is A/D converted and provided to the frame assembly circuit 35 as a digital signal. Reference numeral 39 denotes an instruction input section, which includes dial buttons and various function keys. 40 is a processor (CPU) that controls the entire telephone.

Reference numeral 41 denotes a memory section consisting of 170M and RAM, which is used to store control programs to be executed by the processor 40, its working area, and data.

Reference numeral 42 denotes a switch circuit section, which connects and disconnects the digital network interface circuit and the communication circuit section 37. 4
3 is an IC card that can store data such as the personal number of the other party and the name of the other party, and 44 is an IC card that can read/write the attached IC card.
This is a C card control unit, which connects the 10 card control unit 44 and the EIC card 43, operates the instruction input unit 39, and instructs data such as the personal number of the other party and the name and telephone number of the other party in writing mode. By keying in from 39, the processor 40 reads the IC card nal.
A command to write this data can be given to the 8 section 44, and the manual data can be written into the IC card 43.

45 is a sounder that generates a ringing tone when a call arrives, and 46 is a sounder drive circuit that is controlled by the processor 40 and drives the sounder 25 when a call arrives. Reference numeral 47 denotes an LCD (liquid crystal) display that displays characters and the like using a dot matrix, and displays input from the instruction input section 39, received data, etc. under the control of the processor 40.

The operation of the apparatus having such a configuration will be explained using the connection relationship shown in FIG. 2 as an example, with reference to the flowchart shown in FIG. 4. Incidentally, this flowchart is a procedure for controlling the telephone when a call is received.

Now, suppose that you make a call to the other party from the telephone 10a.

Here, the name used by the telephone 10a on the calling side is IC card 4.
3 into the IC card slot provided in the telephone 10a. It is assumed that data such as the personal number and name of the other party to be called are stored in advance in the IC card 43 along with the telephone number data. Records of the IC card are stored on the phone.
By inserting the C card 43, operating the instruction input section 39 to enter write mode, and inputting the personal number of the other party, the name, telephone number, etc. of the other party, the IC card is read under the control of the processor 40. The control unit 44 operates to write. Of course, in addition to writing from a telephone, a computer or the like may be used.

Then, when the caller performs a dial operation, the processor 40
sends the telephone number resulting from this dialing operation to the frame assembly circuit 35 via the D channel control circuit 34, and
The IC card control unit 4 issues a command to read the memory contents of the c-card.
Give to 4. As a result, the IC card control unit 44
The recorded contents of the card 43 are read and provided to the processor 40. Then, the processor 40 temporarily stores the read contents of the IC card 43 in the memory unit 41, and then stores the personal number and name data registered in the same telephone number as the telephone number dialed by the caller. Search and extract. Incidentally, instead of searching using the IC card data, the personal number may be directly input by manual operation after pressing the function key designated for secret call.

The processor 40 then provides this extracted data to the D channel control circuit 84. Then, the D channel control circuit 34 forms a D channel frame for this data and supplies it to the frame assembly circuit 35. The frame assembly circuit 35 converts the received data into a data string assembled in a predetermined format into transmission data. This converted data is sent to the home bus 30 via the transmission circuit 3B. The exchange 20 receives this data, learns the dialed destination, causes the call to arrive at the telephone 10b of the telephone number of the dialed destination, adds the telephone number data of the caller to the data string, and provides the data to the telephone 10b.

When the telephone 10b receives an incoming call from the network (sl), the reception circuit 31 receives it, the frame decomposition circuit 33 decomposes the data into frames, and the D channel control circuit 34 extracts data, flags, and The control signal is detected and provided to the processor 40 as received information.

The processor 40 first learns of the incoming call from this information, and then obtains the telephone number, personal number, personal name, etc. of the calling party's telephone 10a, if any (S2), and stores them in the memory section 41.

Then, it is checked whether or not there is a personal number in this information (s3), and if there is a personal number, the sounder drive circuit 4
6 is driven to cause the sounder 45 to make a ringer sound, and at the same time, the name information in the received information stored in the memory section 41 is read out and given to the LCD display 47 to control the drive. As a result, the name of the individual to whom the response should be made is displayed on the LCD display 47.

Next, processor 40 of telephone 10b provides I/O to telephone 10b.
Check whether the C card 43 is inserted (s4>,
If an IC card is inserted in the telephone 10b, the personal number recorded in the IC card 43 is compared with the received personal number (s5). Furthermore, s
In step 4, the IC card may be inserted into the telephone lOb after the ringer rings.

Then, the processor 40 determines whether the personal numbers match based on the comparison results (S6), and when the personal numbers match, the processor 40 detects this when the caller picks up the handset 38 and closes the switch circuits 42a and 42b. control so that you can answer and make calls (S
7). Further, in S3, if the personal number is not received, the ringer is made to ring and a normal call is received (S9). When making the ringer ring, the sounder drive circuit 46 is controlled to change the tone of the ringer depending on whether or not a personal number is received, and the tone of the ringer is changed depending on whether a call is received from a specific person or a call from an unspecified person. By distinguishing between calls, you can immediately tell that the call is from a specific person, which will be more convenient.

Also, although the personal number was received in S3,
If the C card 43 is not inserted, or if the IC card 43 is inserted but the personal numbers do not match, the call will only be received until the other party disconnects the line, and even if the handset 38 is picked up, The telephone call circuit section 37 is not connected and telephone calls are not possible (S8). In addition,
In S8, "Personal number does not match", "
By sending a message (such as "The IC card is not inserted into the other party's phone") to the caller, the caller can know the status, so if the IC card is inserted by mistake, etc., the caller will know this. This makes it easier to use.

Further, in S5, a code for an emergency may be determined, and if this emergency code is sent, the call can be received. Alternatively, a switch may be used to switch between incoming calls from a personal number and normal incoming calls.

Although the above is an example of the configuration of a telephone that uses a digital line, an example of the configuration of a telephone that uses an analog line is shown in FIG.

In the figure, 50 is the phone body, 51 is the NCU

The processor 56 controls the IC card by connecting the card 58, operating the instruction input section 55, and inputting data such as the personal number of the other party, the name and telephone number of the other party from the instruction input section 55 in write mode. A command to write this data can be given to the unit 59, and the input data can be written into the IC card 58. 60 is a sounder that generates an incoming ringing tone when an incoming call is received. Reference numeral 61 denotes an LCD display that displays characters and the like using a dot matrix, and displays input from the instruction input section 55, received data, etc. under the control of the processor 56. 62 is a serial output unit (SI) that performs serial communication between the modem 51 and the processor 5B.
O).

This device has a switch circuit inside the modem 51 that connects the four-wire wire 53 and the handset 54 to make a call possible.
Communication between the processor 56 and the network is performed by the SIo 02 and the modem 5.
1, and since the network does not send the calling party's phone number, it cannot be received unless the calling party specifically sends it later. It is the same as the one in Figure 3.

That is, when attempting to call a specific party, the user of the telephone on the calling side inserts the IC card 58 into an IC card insertion portion provided in the telephone. Data such as the personal number and name of the person to be called are stored in advance in the IC card 58 together with the telephone number data. Then, when the caller performs a dial operation, the processor 5G sends the telephone number resulting from this dial operation to the modem 51 via the SIO 62, and the modem 51 receives this and sends a dial signal to the line. Then, when a call is received to the other party's telephone via the exchange, the called party's telephone is connected to the line by the NCU of its own modem 51, so the calling party's telephone
The IC card control unit 59 issues a command to read the memory contents of the card.
give to As a result, the IC card m control unit 59
The recorded contents of the card 58 are read and provided to the processor 56.

Then, the processor 5B reads this read IC card 5.
8 is temporarily stored in the memory section 57, and then the personal number and name data registered in the same telephone number as the telephone number dialed by the caller is searched and extracted. Of course, instead of searching using the IC card data, the personal number may be input directly by pressing a function key for secret call designation and then manually inputting the personal number.

Then, the processor 56 sends this extracted data to the modem 51, so the modem 51 converts this data into a frequency signal and sends it to the line 53.

When the receiving telephone receives an incoming call from the network, the modem 51 receives the call, converts it into digital data, and sends it to the processor 56.
give to From this data, the processor 56 obtains information such as a personal number and personal name from the calling party, if any, and stores these information in the memory section 57. Then, it is checked whether or not there is a personal number in this information, and if there is a personal number, the ringer's I! Command the Fi movement,
The ringer is made to ring from the sounder 6Q, and the name information in the received information stored in the memory section 57 is read out and given to the LCD display 61 for driving control. As a result, the LCD display 61 displays the name of the individual to whom the response should be made. Next, the processor 5B of the receiving phone checks whether an IC card 58 is inserted into its own phone, and if an IC card is inserted, it uses the personal number recorded in the IC card 58 and the received personal information. Match the number. Of course, the IC card may be inserted within a predetermined period of time after the ringer reaches μm1.

Then, the processor 5B checks whether the personal numbers match as a result of the comparison, and when the personal numbers match, it is detected when the caller picks up the handset 54, and the processor 56 connects the handset 54 and the line 53 to the modem 51. In response, the NCU of the modem 51 connects the two to enable voice communication. Further, if the personal number is not received, the processor 56 makes the ringer ring and sends the NCU of the modem 51 to receive a normal call.
give instructions to. In addition, when ringing the ringer, the sound of the ringer changes depending on whether or not a personal number is received. xJL may be configured to distinguish between incoming calls from specified persons and incoming calls from unspecified persons.

Also, although the personal number was received, the IC card 58
is not inserted, or if the IC card 58 is inserted but the personal numbers do not match,
The processor 56 performs only the incoming call operation until the other party disconnects the line, and even if the handset 54 is removed, the call circuit section 52
is not connected to the line 53 so that calls cannot be made.

As detailed above, this device registers a personal number, and when you want to make a confidential call, it sends a personal number (ID code) that identifies the other party, and this personal number is sent. When a call comes in, the personal number is checked against the personal number registered on the called party's telephone, and only when a match is found can a call be made. Therefore, if you are expecting a call from a specific party and the person who should receive the call is near the phone, you can register your own personal number on the phone and delete the registration when you leave the phone. It becomes possible to prevent a third party from receiving incoming calls from a specific party when the person is absent, and it becomes possible for only one person to receive calls from a party who does not want others to know.

The present invention is not limited to the embodiments described above and shown in the drawings, but can be modified and applied as appropriate without changing the gist of the invention. For example, in FIG. 5, the modem is attached to the main body of the telephone. It may also be built-in.
