First, the operation of the first embodiment will be briefly described. PB (Push-Butto) from each telephone 1a, 1n.
The personal identification number based on the (n dialing) signal is transmitted to the PB signal interface (I / F) via the interface (I / F) unit 3 as a telephone connection means having a plurality of telephone connection ports.
F) It is sent to the unit 4 and is notified to the PB signal analysis unit 51 of the control unit 5. Here, the control unit 5 constitutes a permitting means. The PB signal analysis unit 51 analyzes the personal identification number in the PB signal and the port number to which the telephone having the personal identification number input is connected. The calling party number of the person who is talking is the calling party number storage unit 5
3 and the reference unit 52 associates with the port number of the interface unit 3 to which the telephone numbers 1a and 1n to which the personal identification number, the caller's number and the personal identification number are input are associated, and the identification information storage unit is associated. Is stored in the memory 7.
Here, the reference unit 52 constitutes a call permission unit and an individual telephone incoming call notification unit. The personal identification number, the sender number, and the port number respectively associated with each other constitute identification information.

The sender number storage unit 53 is connected to the ISDN network via the ISDN interface (I / F) unit 6. The voice from each of the telephones 1a and 1n passes through the voice route 8 and is ISD through the ISDN interface unit 6.
It is sent to the N network. When a call is received from the ISDN network, the caller number of the caller is notified to the caller number storage unit 53 via the ISDN interface unit 6, and the caller number is stored in the caller number storage unit 53. In the case of the line in which the personal identification number is set, the reference unit 52 notifies the interface unit 3 via the authentication route 10.

At this time, if the telephones 1a, 1n connected to the interface unit 3 are compatible with a number display, the caller numbers are displayed on the telephones 1a, 1n.
The control unit 5 controls so that the caller number is not displayed on the telephones 1a and 1n. Set the PIN code to the telephone 1a, 1
When a PB signal is input from n, the PB signal interface unit 4 is notified via the interface unit 3, and the PB signal analysis unit 51 extracts the personal identification number and the port number of the telephone that responded to the incoming call. The personal identification number associated with the sender number and the port number associated with the personal identification number are read from the memory 7, and the reference unit 52 compares the personal identification number with the port number. When the call is permitted (the password and the port number match), the reference unit 52 notifies the interface unit 3 of the call permission notification for permitting the call through the authorized route 10, and the permitted telephone 1
You can talk with a and 1n. Here, the reference part 5
Reference numeral 2 constitutes a call permission means.

FIG. 2 is a flow chart showing the operation of the communication control system according to the embodiment of FIG. 1, which is a port of the interface section 3 to which the caller number of the sender, the personal identification number and each of the telephones 1a and 1n are connected. The processing when the numbers are stored in association with each other is shown. 1 and 2, a process of storing a caller number of a sender, a personal identification number, and a port number of a telephone capable of receiving an incoming call in association with each other will be described.

In FIG. 2, a predetermined PB signal is operated by operating a predetermined operation button (for example, "*") from a telephone (for example, telephone 1a) in a call during a call with a calling party (call partner). Enter. After this "*", the number of the fixed digit number to be used as the personal identification number is given to the telephone 1a.
Input from the operation button of (step S201). The interface unit 3 uses a predetermined PB signal (in the first embodiment, a PB signal generated by operating the operation button “*”).
Signal (step S202 in FIG. 2), the PB
To the signal interface unit 4, "*", the password following the "*" and the port number of the interface unit 3 to which the telephone set 1a in communication is connected are sent together.

The PB signal interface 4 outputs the received series of PB signals “*”, the personal identification number and the port number to the control unit 5. The PB signal analysis unit 51 deletes the leading PB signal corresponding to “*” included in the received signal, extracts the personal identification number and the port number of a predetermined number of digits, and sends the personal identification number and the port number to the reference unit 52. (Step S203). On the other hand, the telephone number (caller number) of the other party is stored in the caller number storage unit 53 through the ISDN interface unit 6.

When the personal identification number and the port number are input to the reference unit 52, the reference unit 52 is notified of the caller number of the other party in the call stored in the caller number storage unit 53. The reference unit 52 associates the personal identification number and the port number input to the reference unit 52 with the caller number sent from the caller number storage unit 53 (step S204) and stores them in the memory 7 (step S205). ). At this time, the sender number in which the personal identification number and the port number are set is also stored and stored in the sender number storage unit 53.

FIG. 3 is a flowchart showing the operation of the communication control system according to the embodiment of FIG. 1, and shows the processing when the communication control device 2 receives an incoming call. The processing when there is an incoming call from the other party will be described in detail with reference to FIGS. 1 and 3. If there is an incoming call from the ISDN network (step S301), the caller number of the sender is ISDN.
The ISDN interface unit 6 is notified from the network. The caller number storage unit 53 stores the caller number of the caller notified to the interface unit 6.

The reference unit 52 refers to the identification information stored in the memory 7, and determines that the caller number stored in the caller number storage unit 53, that is, the caller number received by the ISDN interface unit 6 is the personal identification number. And the port number are associated with each other to determine whether the caller number has already been set (step S302). The reference unit 52 determines that the caller number is already set when the caller number is stored in the memory 7, and the reference unit 52 does not determine when the caller number is not stored in the memory 7. Judge as the caller ID of the setting. On the other hand, an incoming call to the ISDN interface unit 6 is sent to the interface unit 3 via the voice path 8.

In the case of an incoming call on a line for which no personal identification number is set, the interface section 3 processes it like an ordinary incoming call and calls all the telephones 1a, 1n connected to the interface section 3 (step S307). As a result, the ringers of all the telephones 1a and 1n connected to the interface unit 3 ring, and when one of the telephones 1a and 1n goes off-hook, it becomes possible to make a normal call using the telephones ( Step S308). In this way, in the case of an incoming call from a line for which a caller number is not set, no matter which of the telephones 1a and 1n is used, any user can talk.

In step S302, when the reference unit 52 refers to the memory 7 and determines that the received caller number is the set caller number, the reference unit 52 is referred to.
By notifying the interface unit 3 of the incoming call notification of the existing number, the incoming call from the line for which the personal identification number is set is notified through the authentication route 10. The existing number incoming notification includes a port number associated with the caller number of the sender. The interface unit 3 receives the incoming call notification of the existing number and calls it by ringing the ringer of the telephone of the port number (telephone of the incoming call) included in the incoming call notice of the existing number (step S303).

At this time, if the telephones 1a and 1n connected to the interface unit 3 are compatible with number displays, the caller number will be displayed on the telephone to be called, for example, the telephone 1a. The caller ID is not displayed on the telephone 1a. In step S303, the interface unit 3 causes the ringer of the telephone set 1a to be connected to ring, but the telephone call cannot be made even if the telephone set 1a is off-hook. At that time, the personal identification number is input by the PB signal from the telephone set 1a. That is, the PB signal "*" generated by operating the operation button "*" from the telephone 1a
For example, the previously set personal identification number is input from the telephone 1a by the PB signal following the predetermined PB signal (step S30).
4).

When the interface section 3 detects a predetermined PB signal such as "*", the interface section 3 informs the PB signal interface section 4 of the PB signal input from the telephone set 1a to be connected and the secret code following the PB signal. The number and the port number of the telephone 1a that responded to the incoming call are transmitted. The P
The B signal, the personal identification number based on the PB signal, and the port number are sent to the PB signal analysis unit 51 via the PB signal interface unit 4. The PB signal analysis unit 51 selects the first PB signal “*” from the signal received from the interface unit 4.
Is deleted to extract the personal identification number and port number, and only the input personal identification number is sent to the reference unit 52.

The reference unit 52 reads the personal identification number and the port number corresponding to the originator number of the originator from the memory 7, and the personal identification number and the port number and the PB signal analysis unit 5 are read.
The personal identification number and the port number input from 1 are collated (step S305). The reference unit 52 determines whether the personal identification number input from the connection target telephone 1a and the port number of the telephone 1a match the personal identification number and port number stored in the memory 7 (step S30).
6) If they match, “call permission” is output to the interface unit 3 through the authentication path 10. Step S06 constitutes a call permission means. The interface unit 3 receives the call permission (step S30).
7) Then, the off-hook of the telephone 1a is recognized, and the telephone call of the telephone is enabled (step S308).

On the other hand, if the personal identification numbers do not match in step S306, the telephone 1a is prompted to enter the personal identification number again (step S309), and the regular personal identification number is input within a predetermined number of times. If not, the incoming call is disconnected (step S310). At this time, since the personal identification number is entered by hooking the telephone set 1a off-hook, when the personal identification number does not match, the operator of the telephone set 1a recognizes from the control unit 5 that the personal identification number entered is an incorrect personal identification number. Since the re-input instruction can be discriminated by the PB signal, it is possible to re-input immediately.

When there are a plurality of lines registered with the personal identification number,
The phone number can be recorded like a phone book.
When using a telephone directory, for example, when a different personal identification number is attached to each telephone number, it is not possible to know which number has arrived when receiving a call. Therefore, instead of displaying the telephone numbers on the respective telephones 1a, 1n, the numbers corresponding to the telephone directory are displayed on the respective telephones 1a, 1n.
Display on 1n. For example, the display section of each of the telephones 1a and 1n may display 1, 2, 3, ... In the order of registration in the telephone directory. The phone book also needs to be locked with a PIN so that it is kept confidential.

As described above, when a plurality of telephones are connected to the receiving side and used, only the user who uses the telephone connected to the specific port and who knows the personal identification number can receive the call. You can answer and make a call. Further, by setting the personal identification number during a call, an incoming call from the line next to which the personal identification number is set is not connected unless the personal identification number is input, so that the called party can be specified. Also, the number of lines is not limited to one line, and multiple lines can be set. Therefore, it is possible to protect confidentiality when a call or the like is made from a person who does not want others to know. Further, it becomes possible to set so that only a specific person can talk with a simple operation. In the first embodiment, when the incoming call is received, the personal identification number and the port number associated with the sender's caller number are collated. It may be configured not to output, and only the personal identification number may be collated in step S305. Even in this case, it is configured to call only the telephone set with the personal identification number,
Since only the called telephone can be used, the telephone to be used can be specified.

Next, a second embodiment of the present invention will be described. FIG. 4 is a block diagram of a communication terminal apparatus according to the second embodiment of the present invention, showing an example of a communication control system used in ISDN. In addition, in FIG.
The same reference numerals are given to the same portions as. In the second embodiment, the information communication terminal 11 is provided, and each telephone 1
The personal identification number can be set not only from a and 1n but also from the information communication terminal device 11. Also, the first
In the second embodiment, the personal identification number is set during the call, but in the second embodiment, the personal identification number can be set even after the end of the call. Further, in the first embodiment, a port number associated with a personal identification number or the like is used to permit a call to the telephone when a predetermined personal identification number is input from the telephone connected to the port number. However, in the second embodiment, the port number is not used. That is, if the personal identification numbers match, any telephone can make a call.

The sender number of the sender is the sender number storage unit 5
Since the number is stored in No. 3, the caller number for which the personal identification number is to be set is selected by operating each telephone 1a, 1n, and the personal identification number is input from the telephones 1a, 1n. The procedure for inputting the personal identification number from the telephones 1a and 1b is the same as that in the first embodiment, and a PB signal generated by operating a predetermined operation unit (for example, operation button "*") of the telephones 1a and 1b. After, enter the PIN with a predetermined number of digits. The sender number and the personal identification number associated with the sender number are stored in the memory 7.

Further, when the sender number for which the personal identification number is desired to be set is known in advance, the personal identification number can be set in advance without waiting for the incoming call. For example, each telephone 1
By operating the operation units a and 1b to input a plurality of PB signals, the caller number for which the password is desired to be set and the password to be associated with the caller number are input. Phone 1
The caller number input from a and 1b is stored in the caller number storage unit 53, and the caller number and the personal identification number associated with the caller number are stored in the memory 7.

In the second embodiment, when there is an incoming call, all the telephones 1a and 1b are called. in this case,
When an incoming call is received from a caller number for which a personal identification number has been set, a telephone call can be made by inputting the personal identification number from any of the telephones 1a and 1b.
