Abstract

PROBLEM TO BE SOLVED: To enhance the operability by setting a password to identify a speech party during a speech or after the end of the speech so as to accept an incoming call under the condition of a coincident password without the need for earlier setting or the like. SOLUTION: An interface 13 that detects a predetermined PB signal such as '*' transmits the signal '*' or the like and a succeeding password having already been set to a PB signal interface 14. A PB signal analysis section 16 that receives a series of the PB signals via the PB signal interface eliminates the signal '*' or the like at the head of it and gives only the received password to a reference section 18. The reference section 18 collates a caller number being received and exsisting in a caller number storage section 17 and the password received from the PB signal analysis section 16 with data stored in a memory 19 to discriminate whether or not they are coincident. As a result of the collation, when the received password is coincident with the password stored in the memory 19, the reference section 18 outputs 'speech permission' to the interface 13.

Description of the Related Art Conventionally, there has been known an ISDN communication terminal device having a function of accepting an incoming call on the condition that a registered personal identification number matches when an incoming call is received from the same caller number that has previously arrived.

In such an ISDN communication terminal device, a predetermined password is set in advance to the telephone number of the caller, and the caller dials the password and the telephone number. Only when the password dialed by the caller matches the password of the caller permitted to receive the call, which is also set on the callee, the call can be received and the caller can talk with the callee. .

[0004]

However, in this conventional ISDN communication terminal device, a caller must set a password in advance before dialing.
Operation such as setting by the caller side is required in advance. For this reason, if an incoming call can be accepted on condition that the registered passwords match each other without the necessity of prior setting, etc., the trouble of operation is eliminated and the operability is improved.

An object of the present invention is to improve the operability of an IS that can accept an incoming call on the condition that the registered passwords match each other, without requiring any prior setting or the like.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an IS according to an embodiment of the present invention.
FIG. 3 is a block diagram illustrating a configuration of a DN communication terminal device. FIG.
As shown in FIG. 1, the ISDN communication terminal device 10
1 and the ISDN 12.

[0010] PB (push-but) from the telephone 11
The password of the ton dialing signal is transmitted to the PB signal interface 14 via the interface 13 and notified to the control unit 15. The control unit 15 uses the PB
Signal analysis unit 16, caller number storage unit 17, and reference unit 18
The password of the PB signal is input to the PB signal analysis unit 16.

The PB signal analyzing section 16 analyzes the password of the PB signal. The caller number of the other party during the call is stored in the caller number storage unit 17, and in the reference unit 18,
The personal identification number is associated with the caller number and stored in the memory 19 as storage data.

The caller number storage unit 17 is connected to the ISDN network 12 via the ISDN interface 20. The voice from the telephone 11 passes through the voice path a
The data is transmitted to the ISDN network 12 through the N interface 20.

FIG. 2 is a flowchart showing the operation of the ISDN communication terminal of FIG. As shown in FIG. 2, first, a predetermined PB signal such as “*” is input from the telephone 11 during a call (step S101). After this “*”, a number having a predetermined number of digits as a password is input.

Next, in the interface 13, the PB
A signal is received (step S102). When the interface 13 detects a predetermined “*” or the like,
The input personal identification number having a predetermined number of digits following “*” is transmitted to the PB signal interface 14. A series of Ps received at the PB signal interface 14
The B signal is sent to the PB signal analyzer 16.

Next, the PB signal analysis unit 16
From the B signal, the leading “*” and the like are deleted, and only the password having the determined number of digits is extracted (step S103). The extracted password is sent to the reference unit 18. Reference part 1
When the personal identification number is input to the reference number 8, the caller number during the call stored and stored in the caller number storage unit 17 is notified to the reference unit 18 through the ISDN interface 20.

Next, the personal identification number input by the PB signal in the reference section 18 and the caller number sent from the caller number storage section 17 are associated in the reference section 18 (step S104). Thereafter, the personal identification number and the caller number associated with each other in the reference unit 18 are stored in the memory 19 (step S105). At this time, the caller number for which the password has been set is also stored in the caller number storage unit 17.

FIG. 3 is a flowchart showing a specific operation example when an incoming call is received at the ISDN communication terminal device of FIG. As shown in FIG. 3, first, when there is an incoming call from the ISDN network 12, the caller number is changed to the ISDN interface 2.
0 is notified (step S201).

If the notified caller number is the number stored in the caller number storage section 17, it is determined whether or not a password has been set (step S20).
2). When the password is set (Yes) in the caller ID storage unit 17 by collation of the password, the reference unit 18
Notifies the interface 13 via the authentication path b that an incoming call has come from a line for which a password has been set.

At this time, if the connected telephone set 11 is a caller information notification service (a so-called number display) compatible apparatus, the caller ID is displayed on the telephone set 11 so that the caller ID is not displayed on the telephone set 11. Then, a control command is issued from the control unit 15.

Next, the interface 13 causes the ringer of the telephone connected as before to ring (step S203). At the time of ringing, the telephone cannot be talked even if the telephone is off-hook, and the personal identification number is inputted by the PB signal (step S204). That is, from the telephone 11,
After the preset PB signal such as “*”, the already set password is input.

Next, when a PB signal such as a predetermined “*” is detected in the interface 13 to which the PB signal from the telephone 11 and the personal identification number are input, the interface 13 sends the “*” to the PB signal interface 14. "
And the like, followed by the already set personal identification number (step S205).

PB signal via PB signal interface 14
A series of PB signals sent to the signal analysis unit 16 delete the leading “*” and the like, and refer to only the input personal identification number to the reference unit 1.
Send to 8.

Next, the reference section 18 compares the incoming caller number stored in the caller number storage section 17 and the password transmitted from the PB signal analysis section 16 with the data stored in the memory 19. It is determined whether they match (step S206).

As a result of the collation, if the input personal identification number matches the personal identification number stored in the memory 19 (Yes), "call permitted" is output to the interface 13 through the authentication path b (step S207). "Call permission"
With this input, the interface 13 recognizes that the telephone 11 is off-hook and can make a call (step S208).

On the other hand, the passwords did not match (No)
In this case, the user is prompted again to input a password, and it is determined whether or not the password can be input (step S209). Here, if the correct password can be input within the determined number of times (Y
es), the process returns to step S204, and if an accurate password is not input within the predetermined number of times (No), the incoming call is disconnected (step S210).

In step S202, the personal identification number is
It is not the number stored in the caller number storage unit 17, that is,
If not set (No), the packet is sent to the interface 13 via the voice path a via the ISDN interface 20 (step S209). Therefore, when a call is received on a line for which a password has not been set, the ringer of the connected telephone is sounded and a normal call can be made by going off-hook as in a normal call (step S).
208).

When there are a plurality of lines in which a personal identification number is registered, the telephone number can be recorded like a telephone directory. When this telephone directory is used, for example, if different personal identification numbers are given to the respective telephone numbers, it is not known which number has arrived at the time of the incoming call.

Therefore, instead of displaying the telephone number on the telephone 11, the numbers corresponding to the telephone directory are displayed on the telephone 11, for example, 1, 2, 3,... Note that the telephone directory also needs to be locked with a password or the like so that confidentiality is maintained.

In the above embodiment, the password is set during the call, but the password can be set after the call is over.

Since the caller number is stored in the caller number storage unit 17, the user selects a telephone number for which a password is to be set, and inputs the password from the telephone 11. The input procedure is the same as that described in the above-described embodiment. After a predetermined “*” or the like, a password having a predetermined number of digits is input.

If the caller number for which a personal identification number is to be set is known in advance, the personal identification number can be set first without waiting for an incoming call. When a PB signal is input from the telephone 11, the caller number is stored in the caller number storage unit 17, the password associated with the caller number is stored in the memory 19,
By storing them, when the corresponding caller number is received, as described in the above-described embodiment, a call cannot be made unless a password is input.

FIG. 4 is a block diagram showing the configuration of the ISDN communication terminal device when the input from the ISDN communication terminal device can be set. In the above-described embodiment, the password is input from the telephone. However, a case where the input from the ISDN communication terminal device 10 can be set will be described below.

As shown in FIG. 4, the ISDN communication terminal device 30 is provided with a serial data interface 32 so that an information communication terminal device 31 such as a computer can be connected. Can be set.

That is, the ISDN communication terminal device 30 has a control unit 34 having a serial data analysis unit 33 in addition to the serial data interface 32.
This is the same as the DN terminal device 10.

The ISDN communication terminal device 30 incorporates software for setting / verifying a personal identification number in a line during a call. During a call using the ISDN network 12, a password set on software is input by the information communication terminal device 31. The input personal identification number is transmitted to the serial data analysis unit 33 of the control unit 34 via the serial data interface 32.

The personal identification number received by the serial data analysis unit 33 is sent to the reference unit 18. Caller's number is
It is stored in the caller number storage unit 17 through the ISDN interface 20. When the password is input to the reference unit 18, the caller number during the call stored in the caller number storage unit 17 is notified to the reference unit 18.

The information communication terminal device 31 in the reference unit 18
The personal identification number input by the user and the caller number sent from the caller number storage unit 17 are associated in the reference unit 18,
It is stored in the memory 19. At this time, the caller number for which the password has been set is also stored in the caller number storage unit 17.

Similarly, when there is an incoming call, if the incoming call is from a line for which a personal identification number is set, the ringer of the connected telephone set 11 rings, but no telephone call can be made even if the user goes off-hook. As in the case of the above-described embodiment, when the telephone 11 is a device compatible with a number display, the caller number is displayed, so the control unit 34 does not display the caller number.

The password input by the software on the information communication terminal device 31 is sent to the serial data analysis unit 33 via the serial data interface 32, and the reference unit 18 checks the password.

As a result of the collation, if the passwords match, a call permission is sent to the interface 13 through the authentication path b, and a call can be made. On the other hand, if the PIN does not match, the user is prompted to enter the PIN again,
If the correct password cannot be entered within the specified number of times, the incoming call is disconnected.

As described above, according to the present invention, the personal identification number based on the PB signal is input from the telephone 11 to the line during the call, and the personal identification number and the number stored in the caller number storage unit 17 are referred to. By associating at 18 and storing in the memory 19, if there is an incoming call from the same caller number thereafter, the incoming call can be received by inputting the stored password.

In other words, incoming calls after setting of the line in which the password is set cannot be connected without inputting the password, but the identification of the caller based on the password can be performed during or after the call. This is possible with a simpler setting operation, and since there is no need to perform an operation such as setting a password in advance by the caller before dialing, operability is improved.

[0043]

As described above, according to the present invention, a caller is specified during or after a call in an ISDN communication terminal device having a function of receiving an incoming call on condition that a password matches. Since the setting of the personal identification number is performed, the incoming call can be accepted on condition that the registered personal identification numbers coincide with each other, without the necessity of a prior setting or the like, and the operability can be further improved.
