DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a communication control system and a communication control device according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of a communication control system according to the first embodiment of the present invention, and shows an example of an ISDN communication control system used in ISDN.
In FIG. 1, the communication control system includes a plurality of telephones 1 a and 1 n and an ISDN communication control device 2.
The communication control device 2 is connected between the plurality of telephones 1a and 1n and the ISDN network.
[0013]
First, an outline of the operation of the first embodiment will be described. A personal identification number by a PB (Push-Button dialing) signal from each telephone 1a, 1n is an interface as a telephone connection means having a plurality of telephone connection ports ( The data is sent to the PB signal interface (I / F) unit 4 via the (I / F) unit 3 and notified to the PB signal analysis unit 51 of the control unit 5. Here, the control part 5 comprises the permission means.
The PB signal analysis unit 51 analyzes the PIN number in the PB signal and the port number to which the telephone set with the PIN number is connected. The caller number of the other party during the call is stored in the caller number storage unit 53, and in the reference unit 52, the interface unit to which the telephone number 1a, 1n to which the code number, the caller number and the code number are input is connected. 3 port numbers are associated with each other and stored in the memory 7 as identification information storage means. Here, the reference unit 52 constitutes a call permission unit and an individual telephone incoming call notification unit. Each of the associated password, caller number and port number constitutes identification information.
[0014]
The caller number storage unit 53 is connected to the ISDN network via the ISDN interface (I / F) unit 6. Voices from the telephones 1 a and 1 n are sent to the ISDN network through the voice path 8 and the ISDN interface unit 6.
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 a line for which a personal identification number is set, the reference unit 52 notifies the interface unit 3 via the authentication path 10.
[0015]
At this time, if the telephones 1a and 1n connected to the interface unit 3 are number display compatible machines, the caller number is displayed on the telephones 1a and 1n, so the control unit 5 displays the caller number on the telephones 1a and 1n. Control not to. When the set password is input as a PB signal from the telephones 1a and 1n, the PB signal interface unit 4 is notified via the interface unit 3, and the PB signal analysis unit 51 receives the code number and the port of the telephone that responds to the incoming call. The number is extracted, and the code number associated with the caller number of the incoming call and the port number associated with the code number are read from the memory 7, and the code number and the port number are collated by the reference unit 52. When the call is permitted (when the password and the port number match), the reference unit 52 notifies the interface unit 3 of a call permission notification for permitting the call via the authorized path 10, and the permitted telephone 1a, You can talk on 1n. Here, the reference unit 52 constitutes a call permission unit.
[0016]
FIG. 2 is a flowchart showing the operation of the communication control system according to the embodiment of FIG. 1, and corresponds to the caller number of the caller, the personal identification number, and the port number of the interface unit 3 to which the telephones 1a and 1n are connected. The process in the case of adding and storing is shown.
Hereinafter, the processing in the case of storing the caller number of the caller, the personal identification number, and the port number of the telephone capable of answering incoming calls in association with each other will be described with reference to FIGS.
[0017]
In FIG. 2, a predetermined PB signal is input by operating a predetermined operation button (for example, “*”) from a telephone (for example, the telephone 1a) during a call during a call with a caller (calling party). . After this “*”, a number having a predetermined number of digits as the password is input from the operation button of the telephone 1a (step S201).
When the interface unit 3 receives a predetermined PB signal (PB signal generated by operating the operation button “*” in the first embodiment) (step S202 in FIG. 2), the PB signal interface unit 4 The personal identification number following “*” and “*” and the port number of the interface unit 3 to which the telephone 1a in communication is connected are sent together.
[0018]
The PB signal interface 4 outputs the received series of the PB signal “*”, the password 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 code number and port number having a predetermined number of digits, and sends them 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.
[0019]
When the personal identification number and the port number are input to the reference unit 52, the caller number of the other party who is in a call stored in the caller number storage unit 53 is notified to the reference unit 52. The reference unit 52 associates the code number and port number input to the reference unit 52 with the caller number sent from the caller number storage unit 53 (step S204) and stores it in the memory 7 (step S205). ). At this time, the caller number in which the code number and the port number are set is also stored in the caller number storage unit 53.
[0020]
FIG. 3 is a flowchart showing the operation of the communication control system according to the embodiment of FIG. 1, and shows 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.
When there is an incoming call from the ISDN network (step S301), the originator caller number is notified from the ISDN network to the ISDN interface unit 6. The caller number storage unit 53 stores the caller number of the caller notified to the interface unit 6.
[0021]
The reference unit 52 refers to the identification information stored in the memory 7, and the caller number stored in the caller number storage unit 53, that is, the caller number received by the ISDN interface unit 6, is a password number and a port number. To determine whether the caller number has already been set (step S302). When the caller number is stored in the memory 7, the reference unit 52 determines that the caller number is already set, and when the caller number is not stored in the memory 7, the reference unit 52 Judged as the set caller ID.
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.
[0022]
In the case of an incoming call on a line for which a personal identification number is not set, the interface unit 3 processes like a normal incoming call and calls all the telephones 1a and 1n connected to the interface unit 3 (step S307). As a result, when the ringers of all the telephones 1a and 1n connected to the interface unit 3 ring and one of the telephones 1a and 1n is off-hooked, it becomes possible to perform a normal call using the telephone ( Step S308). In this way, in the case of an incoming call from a line for which no caller number is set, any user can make a call regardless of which telephone 1a, 1n is used.
[0023]
In step S <b> 302, when the reference unit 52 refers to the memory 7 and determines that the received caller number is an already set caller number, the reference unit 52 calls the existing number to the interface unit 3. By notifying the notification, it is notified through the authentication path 10 that an incoming call has arrived from the line for which the personal identification number is set. The existing number incoming call notification includes a port number associated with the caller number of the caller.
The interface unit 3 receives the existing number incoming call notification and calls it by ringing the ringer of the telephone of the port number (the incoming call target telephone) included in the existing number incoming call notification (step S303).
[0024]
At this time, if the telephones 1a and 1n connected to the interface unit 3 are number display compatible machines, the caller number is displayed on the telephone to be received, for example, the telephone 1a. Do not display caller ID on.
In step S303, the interface unit 3 rings the ringer of the telephone 1a to be connected, but no telephone call can be made even if the telephone 1a is off-hooked, and at that time, the personal identification number is input from the telephone 1a as a PB signal. That is, a password that has already been set subsequent to a predetermined PB signal, such as a PB signal “*” generated by operating the operation button “*” from the telephone 1a, is input from the telephone 1a using the PB signal (step S304).
[0025]
When the interface unit 3 detects a predetermined PB signal such as “*”, the PB signal input from the telephone 1 a to be connected to the PB signal interface unit 4, the subsequent PIN and incoming call The port number of the telephone 1a responding to is sent out.
The PB signal, the password number by 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 analyzing unit 51 deletes the head PB signal “*” from the signal received from the interface unit 4 to extract the code number and the port number, and sends only the input code number to the reference unit 52.
[0026]
The reference unit 52 reads the password number and port number corresponding to the caller number of the caller from the memory 7, and the password number and port number input from the PB signal analysis unit 51. Are collated (step S305).
The reference unit 52 determines whether or not the personal identification number and the port number of the telephone 1a input from the telephone 1a to be connected match the personal identification number and the port number stored in the memory 7 (step S306). If they match, “permit call” is output to the interface unit 3 through the authentication path 10. Step S06 constitutes a call permission means.
Upon receiving the call permission (step S307), the interface unit 3 recognizes the off-hook of the telephone 1a and enables the telephone call (step S308).
[0027]
On the other hand, if the passwords do not match in step S306, the telephone 1a is prompted to input the password again (step S309), and the regular password is not input within a predetermined number of times. The incoming call is disconnected (step S310). At this time, since the personal identification number is input by off-hooking the telephone 1a, the operator of the telephone 1a confirms that the input personal identification number is an incorrect personal identification number when the personal identification number does not match. Since the re-input instruction can be discriminated by the PB signal, re-input can be performed immediately.
[0028]
When there are a plurality of lines registered with a personal identification number, the telephone number can be recorded like a telephone directory. When using a telephone directory, for example, when a different personal identification number is assigned to each telephone number, it is not known which number has arrived when the incoming call is received. Therefore, instead of displaying telephone numbers on the telephones 1a and 1n, numbers corresponding to the telephone directory are displayed on the telephones 1a and 1n. For example, you may make it display on the display part which each telephone 1a, 1n has as 1, 2, 3, ... in the registration order of a telephone directory. The phone book also needs to be locked with a PIN so that it can be kept confidential.
[0029]
As described above, when multiple telephones are connected to the receiving side, only the user who uses the telephone connected to a specific port and knows the security code answers the incoming call. You can make a call.
In addition, by setting a personal identification number during a call, incoming calls from the next line on which the personal identification number is set are not connected unless the personal identification number is entered, so that the caller on the receiving side can be specified. Further, the number of lines is not limited to one line, and a plurality of lines can be set.
Therefore, it is possible to protect confidentiality in the case of a call from a partner who does not want to be known to others. In addition, it is possible to set so that only a specific person can make a call with a simple operation.
In the first embodiment, when there is an incoming call, the PIN number and the port number associated with the caller ID of the caller are collated. It may be configured not to output, and may be configured to collate only the password in step S305. In this case as well, only the telephone set with the code number is called, and only the called telephone can be used, so that the telephone to be used can be specified.
[0030]
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, and shows an example of a communication control system used in ISDN. In FIG. 4, the same parts as those in FIG.
In the second embodiment, an information communication terminal 11 is provided, and the personal identification number can be set not only from the telephones 1a and 1n but also from the information communication terminal apparatus 11. In the first embodiment, the personal identification number is set during a call. In the second embodiment, the personal identification number can be set even after the call ends. In the first embodiment, a port number associated with a personal identification number or the like is used, and when a predetermined personal identification number is input from a telephone connected to the port number, a telephone call is permitted to the telephone. However, in the second embodiment, the port number is not used. In other words, any telephone can be used to make a call if the passwords match.
[0031]
Since the caller number of the caller is stored in the caller number storage unit 53, the caller number for which the password is desired to be set is selected by operating each of the telephones 1a and 1n, and the password is set from the telephones 1a and 1n. input. The procedure for inputting the personal identification number from the telephones 1a and 1b is the same as in the first embodiment, and a PB signal generated by operating a predetermined operation unit (for example, the operation button “*”) of the telephones 1a and 1b. After that, a password with a predetermined number of digits is entered. The caller number and the personal identification number associated with the caller number are stored in the memory 7.
[0032]
In addition, when the caller ID for which a password is desired to be set is known in advance, the password can be set first without waiting for an incoming call. For example, by operating the operation units of the telephones 1a and 1b and inputting a plurality of PB signals, a caller number for which a password is to be set and a password associated with the caller number are input. The caller number input from the telephones 1 a and 1 b is stored in the caller number storage unit 53, and the caller number and the password associated with the caller number are stored in the memory 7.
[0033]
In the second embodiment, when there is an incoming call, all the telephones 1a and 1b are called. In this case, when a caller ID for which a password has been set is received, a call can be made by inputting the password from one of the telephones 1a and 1b.
Hereinafter, the operation of the second embodiment will be described in detail with reference to FIGS. 1 and 4.
A serial data interface unit 12 is provided in the communication control device 2 so that an information communication terminal 11 such as a computer can be connected.

The password is sent from the information communication terminal 11 to the serial data analysis unit 13 of the control unit 5 via the serial data interface (I / F) unit 12. The serial data analysis unit 13 receives the password and sends it to the reference unit 52.
The caller number of the other party (caller) is stored in the caller number storage unit 53 via the ISDN interface unit 6.
[0035]
When the personal identification number is input to the reference unit 52, the caller number during a call stored in the caller number storage unit 53 is notified to the reference unit 52.
The reference unit 52 stores the password entered from the information communication terminal 11 and the caller number sent from the caller number storage unit 53 in the memory 7 in association with each other. At this time, the caller number set with the password is also stored in the caller number storage unit 53.
Through the series of processes, the personal identification number is set in association with the caller number during the call.
[0036]
Next, an operation for setting a personal identification number in association with a caller number during a non-call will be described.
Since the caller number (phone number) received so far is stored in the caller number storage unit 53, the telephone number can be set from either the telephone 1a or the telephone 1n (either the telephone 1a or the telephone 1n). For the sake of convenience, the following description will be made assuming that the hand password is set by using the telephone 1a.) By selecting the caller number (phone number) for which the password is to be set, the password is entered from the telephone 1a. To do.
