Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial application field) The present invention relates to a telephone capable of making a call only between designated parties.

(Prior Art) A conventional telephone can call a partner of the telephone number by operating a push button, a rotary dial, or the like provided on the telephone and dialing the other party's number.
When a call is received, the handset (handset) is turned off-hook.
Alternatively, by pressing a function button such as "loud voice call", anyone can easily make a response call for all incoming calls. However, in the case of a phone call that is equivalent to the letter "confidential", that is, if you want to talk to a designated person, and if the designated person is not nearby, talk with the person who picked up the handset, It is necessary to have the other party called. In some cases, a call from a particular person may not want to be known to others, and in such a case, the person waiting for the call should make sure that another person does not pick up the handset for the call. You have to wait around the phone and pick up the handset first when you receive a call.

(Problems to be Solved by the Invention) Conventional telephones can call the other party by dialing the other party's number, and anyone can easily pick up the handset when receiving a call. You can now answer calls. However,
In many cases, you want to talk only to the designated person, and you do not want to be able to answer the call to others other than the designated person.In this case, if there is an incoming call from that specific person in advance If you know, wait around the phone to prevent others from picking up the handset for an incoming call, and when you receive a call, you have to pick up the handset first, or you come in unexpectedly In such cases, it is impossible to prevent others from leaving.

As described above, the conventional telephone has no restriction on responding to an incoming call, and there is a problem in that it is not possible to specify a party to answer when making a call.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a specific person communication function that allows only a specific person to make a call when an incoming call is received, so that a call requiring a secret can be performed with security, It is an object of the present invention to provide a telephone which can reduce the operational burden on the user and makes it possible for the caller to clearly know the reason when a call cannot be made with the called party.

[Configuration of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. That is, when an incoming call arrives from the network, an incoming call notification operation is started, and it is first determined whether or not a personal identification code designating an incoming call respondent from the calling side has arrived. And when the arrival of this personal identification code is detected,
It monitors whether or not the portable storage medium is mounted during an arbitrary period including after the start of the notification of the incoming call, and reads out the individual identification code stored from the portable storage medium when the portable storage medium is mounted, The read personal identification code is collated with the received individual identification code to determine whether both codes match. If it is determined that they match, the caller and the incoming call responder are connected to enable communication, and if they do not match, the communication is set to the communication disabled state and the communication is disabled. A possible reason, that is, a message indicating that the portable storage medium is not mounted or that the individual identification code does not match as a result of the collation, is sent to the calling side.

(Operation) In such a configuration, when a call requiring confidentiality is desired, a personal identification code (ID code) for specifying the other party is transmitted by the personal identification code transmitting means at the time of calling. Upon receiving the call, the receiving side reads the attached ID code when receiving the ID code, compares the read ID code with the received ID code, and controls the call to be permitted only when the ID code matches. At the time of receiving a call, when no ID code is received, anyone who answers the called telephone can talk on the telephone in the same manner as a normal telephone.

In this way, the device registers the ID code, and if you want to make a confidential call, the ID that identifies the other party's caller
A code was sent, and when this ID code was sent, the call was made possible only when the called party matched the ID code stored in advance in the portable storage medium attached to the called party by the answering party and matched. Things. Therefore, when an incoming call is expected from a specific party, when the person to receive the incoming call is near the telephone, the portable storage medium storing the ID code of the user is attached to the telephone, and when the user leaves the telephone, the portable storage medium is stored. By removing the media from the phone, you can prevent third parties from receiving calls from specific parties when you are not present, and you can only receive such calls from parties you do not want others to know Become like

Therefore, according to the present invention, it is possible to prevent a third party from receiving an incoming call from a specific party, to receive only such a call from a party who does not want to be known to others, and to require a secret. It is possible to provide a telephone capable of making a call with security.

In addition, when inputting his / her own identification code into the telephone, the incoming call responder only needs to attach his / her own portable storage medium to the telephone, so it is necessary to input the individual identification code by key operation for each incoming call. In this way, it is possible to reduce the operational burden on the incoming call responding person and prevent an input error from occurring, so that a reliable incoming call can be always answered.

Further, according to the present invention, when the portable storage medium is not mounted, or when the communication is set to the communication disabled state, such as when the two codes do not match as a result of the collation of the individual identification code, By sending the message indicating the reason to the calling party, the calling party can clearly know the reason why the call cannot be made with the called party.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of this apparatus. As shown in FIG. 1, a network connection means 11 such as a modem or an ISDN interface, an analog communication circuit unit 13 to which a handset 12 is connected, and an analog communication circuit A switch circuit unit 14 for connecting the unit 13 with the network connection unit 11; a communication control unit 15 for controlling a call to send or receive and detect a personal number (personal identification code; ID code); A designated responder identification code input means 16 for inputting a personal number of a designated responder to be sent to the user; a called responder identification code registration storage means 17 for registering and storing a personal number of a person who answers the call; And a comparing and comparing means 18 for comparing and comparing the personal number of the designated responder from the telephone number with the personal number of the called respondent registered and stored in the called respondent identification code registration storage means 17. To.

The telephone having such a configuration is connected to the exchange 20 via a line as shown in FIG. In the digital switching network, there is a service for notifying the telephone number of the calling telephone device, which is used when calling from the calling telephone device.
This function sends a call setup message containing the information element to be transmitted to the network, and the network automatically adds the information element of the calling telephone number to this and sends it to the called telephone device.
Use this function.

When a call is made from the telephone 10a, the calling party performs a dial operation to input the dial information and the personal number of the designated responder from the designated responder identification code input means 16 of the telephone 10a used by the calling party. Send to 20.
As a result, the exchange 20 makes the telephone set 10b of the number dialed by the caller receive a call and transmits the personal number. When receiving a call, the telephone 10b checks whether or not a personal number has been received, and if a personal number has been received, the personal number of the designated responder stored in the incoming responder identification code registration storage unit 17 is received. The personal identification number is compared and collated by the comparison and collation means 18. Then, as a result of the comparison and collation, if they match, there is a coincidence output from the comparison and collation means 18, whereby the switch circuit unit 14 is closed to enable a voice call.

Therefore, in this device, if you want to make a call only between specific parties, and you do not want to be picked up by another person, you must tell your own personal numbers and call the person near the telephone of the called party. If there is a party, if the party registers its own personal number in the incoming call responder identification code registration storage means 17, if the personal number is transmitted by the caller at the time of calling, the call will be received at the other party. In addition, it is possible to make a call only between parties who have signed up in advance, and it is possible to avoid the inconvenience of not being able to call another person because they are not nearby. Also, when the user temporarily leaves or becomes absent, if his / her personal number is canceled from his / her own personal number registration in the incoming call responder identification code registration / storage means 17 in his / her telephone, the other party can enter the personal number. Even if a call is made by specifying a personal number, the call cannot be made to the other party's telephone, so that the inconvenience of calling another person can be avoided. If no personal number has been received, the same control as for a normal incoming call is performed.

FIG. 3 shows a more specific configuration of the present apparatus. The figure is a block diagram showing the detailed configuration of this telephone.This telephone is connected to the basic interface of ISDN, and each individual can have a dedicated one so that a private call can be easily made, for example, an IC.

Connect IC card 43 to section 44,
By operating the instruction input unit 39 and keying in data such as the personal number of the call partner and the name and telephone number of the other party from the instruction input unit 39 as the write mode, the processor 40 sends the data to the IC card control unit 44, By giving a write command, the input data can be written into the IC card 43. Reference numeral 45 denotes a sounder that generates a ringing sound when a call arrives, and reference numeral 46 denotes a sounder driving 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 in a dot matrix.
The input and received data are displayed under the control of the processor 40.

The operation of this device having such a configuration will be described with reference to the flowchart of FIG. 4 taking the connection relationship of FIG. 2 as an example. still,
This flowchart is a control procedure of the telephone when receiving a call.

Now, it is assumed that the telephone 10a makes a call to the other party.
Here, the user of the telephone set 10a on the calling side inserts the IC card 43 into the IC card insertion section provided in the telephone set 10a. It is assumed that data such as the personal number and name of the other party are stored in the IC card 43 in advance together with the data of the telephone number. The recording of the IC card is performed by attaching the IC card 43 to the telephone, operating the instruction input unit 39 to set the writing mode, and then inputting the personal number of the call partner, the name and telephone number of the call partner, etc. Under the control, the IC card control unit 44 operates and writes. of course,
In addition to the method of writing from a telephone, a personal computer or the like may be used.

Then, when the caller operates the dial, the processor 40
Sends the telephone number by this dialing operation to the frame assembling circuit 35 via the D-channel control circuit 34, and gives a command to read the stored contents of the IC card to the IC card control unit 44. As a result, the IC card control unit 44 reads the recorded contents of the IC card 43 and supplies the read contents 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. Instead of searching with IC card data, a personal key may be directly input by manual operation after pressing a function key for designating a secret call.

Then, the processor 40 supplies the extracted data to the D channel control circuit 34. Then, the D channel control circuit
34 forms a D-channel frame for this data and supplies it to the frame assembling circuit 35. Frame assembly circuit 35
Converts the received data into a data string assembled in a predetermined format in the transmission data. The converted data is sent to the home bus 30 via the transmission circuit 36. The exchange 20 receives the data, knows the dial destination, causes the telephone 10b of the telephone number of the dial destination to receive a call, and adds the telephone number data of the caller to the above-mentioned data string, and
Give to 10b.

When the telephone 10b receives an incoming call from the network (s1), the receiving circuit 31 receives the incoming call, and the frame decomposing circuit 33 decomposes the data into frames. The D-channel control circuit 34 outputs the data, flags, The control signal is detected and given to the processor 40 as reception information. Processor
40 first knows the incoming call from this information, then the caller's telephone
If there is a telephone number, personal number, personal name, etc. of 10a, these information are obtained (s2) and stored in the memory unit 41. Then, it is checked whether or not there is a personal number in this information (S3). If there is a personal number, the sounder drive circuit 46 is driven, the ringer sounds from the sounder 45, and the above-mentioned reception stored in the memory unit 41 is stored. The name information in the information is read out and given to the LCD display 47 for drive control. As a result, the individual name to be responded is displayed on the LCD display 47. Next, the processor 40 of the telephone 10b has an IC
Check whether the card 43 is inserted (s4), and
In 10b, if the IC card is inserted, the personal number recorded in the IC card 43 is compared with the received personal number (s5). In s4, an IC card may be inserted into the telephone 10b after the ringer rings.

Then, as a result of the comparison and collation, the processor 40 determines whether or not they match (s6). If the personal numbers match, the caller picks up the handset 38 and detects this, and the processor 40 switches the switch circuits 42a and 42b. Is closed so that answering and talking can be performed (s7). If the personal number is not received in s3, the ringer is sounded and a normal incoming call is made (s9). When sounding the ringer, the sounder drive circuit 46 changes the tone of the ringer depending on whether or not a personal number has been received.
Is controlled, and the ringer tone is distinguished between an incoming call from a specific person and an incoming call from an unspecified person.

Also, the personal number was received in s3, but IC
If the card 43 has not been inserted, or if the IC card 43
Is inserted but the personal numbers do not match, only the incoming call operation is performed until the other party disconnects the line,
Even if the handset 38 is picked up, the communication circuit unit 37 is not connected, so that a call cannot be made (s8). In s8,
"Personal numbers do not match", "IC is
If you send a message such as `` No card inserted '' to the other party, the caller can know the status, so IC
This makes it easier to use because you can know this when you insert the card by mistake. Further, in s5, a code or the like in case of emergency may be determined, and if the emergency code is sent, incoming calls may be made. In addition, an incoming call using a personal number and a normal incoming call may be switched by a switch.

The above is a configuration example of a telephone using a digital line. FIG. 5 shows a configuration example of a telephone using an analog line.

In the figure, 50 is a telephone body, 51 is a modem with a built-in NCU (network control device), which controls outgoing / incoming calls, converts data into frequency signals and sends them out, and also receives received frequency signals. It is to be converted to data. Reference numeral 52 denotes a communication circuit unit having a built-in speech network circuit capable of ringing a ringer at the time of an incoming call and transmitting and receiving a voice signal between a line 53 and a handset 54 via a modem 51. An instruction input unit 55 has various function keys in addition to dial buttons. 56 is a processor (CPU) that controls the entire telephone. Reference numeral 57 denotes a memory unit composed of a ROM and a RAM, which is used for storing a control program to be executed by the processor 56, a working area thereof, data, and the like.

58 is an IC card capable of storing data such as the personal number of the call partner and the name of the other party, and 59 is an IC card control unit capable of reading / writing the mounted IC card. The IC card 58 is connected to the unit 59, the instruction input unit 55 is operated, and data such as the personal number of the call partner and the name and telephone number of the other party are keyed in from the instruction input unit 55 as the write mode. Is a command that gives a command to write this data to the IC card control section 59, and allows the IC card 58 to write the input data. Reference numeral 60 denotes a sounder that generates a ringing tone when a call is received. Reference numeral 61 denotes an LCD display for displaying characters and the like in a dot matrix.
Is displayed under the control of. Reference numeral 62 denotes a serial input / output unit (SIO) for performing serial communication between the modem 51 and the processor 56.

This device has a switch circuit inside the modem 51 that connects the line 53 and the handset 54 to enable communication, and that communication between the processor 56 and the network is performed via the SIO 62 and the modem 51. This is basically the same as that of FIG. 3 except that the telephone number of the caller is not transmitted by the network and cannot be received unless the caller transmits it later.

That is, when trying to call a specific party, the user of the calling telephone set the IC card 58 on the telephone.
Insert it into the IC card slot. In the IC card 58, data such as the personal number and name of the other party is stored in advance together with the data of the telephone number. Then, when the caller performs a dialing operation, the processor 56 sends the telephone number by the dialing operation to the modem 51 via the SIO 62, and the modem 51 receives this and sends out a dial signal to the line. Then, when a call is received to the other party's telephone via the exchange, the called telephone is connected to the line by the NCU of its own modem 51, so the transmitting telephone issues a command to read the stored contents of the IC card next. This is given to the IC card control unit 59. As a result, the IC card control section 59 reads the recorded contents of the IC card 58 and gives it to the processor 56. Then, the processor 56 temporarily stores the read content of the IC card 58 in the memory unit 57,
Next, data of the personal number and name registered in the same telephone number as the telephone number dialed by the caller is searched and extracted. Of course, instead of searching with IC card data, a personal key may be directly input by manual operation after pressing a function key for designating secret communication or the like.

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

When the receiving telephone receives an incoming call from the network, it is received by the modem 51, converted into digital data, and supplied to the processor 56. If there is a personal number, a personal name, and the like from the calling party based on this data, the processor 56 obtains such information and stores it in the memory unit 57. Then, it was checked whether or not there was a personal number in this information, and if there was a personal number, the ringing of the ringer was instructed to the calling circuit unit 52, and the ringer was sounded by the sounder 60, and stored in the memory unit 57. The name information in the received information is read and the LCD display 6
Drive control by giving to 1. As a result, the personal name to be responded is displayed on the LCD display 61. Next, the processor 56 of the called telephone checks whether or not the IC card 58 is inserted in its own telephone.
The personal number recorded in the IC card 58 is compared with the received personal number. Of course, the IC card may be inserted within a predetermined time after the ringer rings.

Then, the processor 56 checks whether or not they match as a result of the comparison and collation. If the personal numbers match, the processor 56 detects that the caller picks up the handset 54, and
56 instructs the modem 51 to connect the handset 54 to the line 53, whereby the NCU of the modem 51 connects the two to enable voice communication. If the personal number has not been received, the processor 56 sounds the ringer and gives a command to the NCU of the modem 51 to perform a normal incoming call.
When the ringer is caused to ring, the tone of the ringer may be changed depending on whether or not a personal number has been received, so that an incoming call from a specific person and an incoming call from an unspecified person can be distinguished.

If the personal number is received but 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 arrives until the other party disconnects the line. Only the call operation is performed, and even if the handset 54 is picked up, the communication circuit unit 52 is not connected to the line 53, so that a call cannot be made.

As described above in detail, the present apparatus registers a personal number and, when a call requiring confidentiality is desired, sends a personal number (ID code) for identifying the other party's caller, and this personal number is sent. When a call comes in, a call is made possible only when the personal number registered in the called telephone is matched with the personal number. Therefore, if you are expected to receive a call from a specific party, register your personal number when you are near the phone, and delete the registration when you leave the phone. It is possible to prevent a third party from receiving an incoming call from a specific party when is not present, and to receive only such a call from a party who does not want to be known to others.

The present invention is not limited to the embodiment described above and shown in the drawings, but can be implemented by appropriately modifying it without departing from the scope of the invention. For example, in FIG. It may be built in.

〔The invention's effect〕

As described in detail above, according to the present invention, it is possible to prevent a third party from receiving an incoming call from a specific party, so that only oneself can receive such a call from a party who does not want to be known to others. In addition, it is possible to provide a telephone which can reduce the operational burden on the called party and allow the calling party to clearly understand the reason when a call cannot be made with the called party.
