BEST MODE FOR CARRYING OUT THE INVENTION Next, a first embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a block diagram of the entire system including the embodiment of the present invention. Figure 2
Referring to the block diagram of the entire system, the exchange 1 that supports the password input to the called party (hereinafter referred to as the called party designation service), the exchanges 2 and 3 that do not perform the called party designation service, and the terminals 61, 62, 63 and line 7
1, 72, 73 and inter-office lines 74, 75. It should be noted that although there are a plurality of terminals, three terminals are used for convenience of explanation. Also, the communication network in this system is the exchanges 1, 2,
3, lines 71, 72, 73 and inter-station lines 74, 75 are included.

The exchange 1 includes a switch device 11 for controlling a communication path between subscribers, an announcement device 12 for giving an announcement to a caller or a callee through the switch device 11, and a caller or callee for the caller through the switch device 11. Receiver device 1 for receiving dialed numbers
3, a storage unit 15, a switch device 11, an announcement device 12, a receiver device 13, and a control device 14 that controls the storage device 15.

The storage unit 15 stores a called party telephone number table required to request the called party to input a password. The called party telephone number table is composed of a called party specific number corresponding to the called party and a password corresponding to the called party for each called party telephone number indicating the called party's telephone number. The storage unit 15 also has an area for temporarily storing the dialed incoming number and the called party identification number. The storage unit 15 is preferably a non-volatile memory or recording medium that retains its contents even when the power is turned off.

Next, the operation of this embodiment will be described with reference to FIGS. In FIG. 2, assume that a call is made from the terminal 63, which is the originator, to the terminal 62, which is the recipient, as an example. Change the telephone number of the terminal 62 to "03-4
44-7888 "and the called party identification number is" 3 ". The password is “1234”. These are registered in the called party telephone number table of the storage unit 15 by the exchange maintenance person at the time of the service contract as shown in FIG. The area code of the exchange 1 at this time is "03". Also,
The telephone number of the message reproducing service is "500", and the telephone number of the password changing service is "501".

The caller off-hooks the terminal 63 and dials the telephone number "0344447888". Then, the signal carrying the telephone number "0344447888" is the line 7
3, exchange 3, interoffice line 75, exchange 2, interoffice line 74
Is transmitted to the exchange 1 via. Upon receiving this signal via the switch device 11, the receiver device 13 of the exchange 1 passes control to the control device 14. The control device 1 reads the called telephone number table of the storage device 15 and then calls the called party telephone number table (hereinafter, when the control device 15 searches the called party telephone number table, the reading operation is omitted for convenience of description. It is checked whether the called party telephone number "0344447888" is registered in the mere called party telephone number table (step S1 in FIG. 1).

When the called party telephone number is registered in the called party telephone number table, the control device 14 operates the announcement device 12 to send the announcement information to the caller's terminal 63 through the switch device 11, and the terminal 63 The caller is notified of the announcement of the request to enter the callee identification number (steps S2 and S3).

The caller sends the callee identification number "3" to the terminal 63.
When dialed (input) to, it is transmitted to the exchange 1. The receiver device 13 of the exchange 1 receives the callee identification number “3” and passes control to the control device 14. The control device 14
When the callee identification number "3" is received, it is checked whether the password corresponding to the callee identification number is registered in the callee telephone number table (steps S4 and S5).

When the password corresponding to the called party identification number is registered in the called party telephone number table, the control unit 14 calls the terminal of the called party telephone number as usual and makes the calling party hear the call back tone. (Steps S6, S
7).

When the called terminal 62 goes off-hook,
The control device 14, which has detected the off-hook via the line 3, the switch device 11, and the receiver device 13, operates the announcement device 12 so as to request the password corresponding to “3”, and sends the announcement information to the terminal 62 through the line 3. By doing so, the callee is notified of the password request announcement (steps S8 and S9).

The called party dials (inputs) the password "1234" corresponding to the called party identification number "3". In this case, the callee who picks up the handset first hands over the handset to the person corresponding to the callee identification number by listening to the password input request announcement for the callee identification number. Then, the person who receives it will dial (input) his password. Receiver device 13 of exchange 1
Receives the dialed (input) password via the switch device 11 and passes control to the control device 14. The control device 14 compares the received password with the password in the callee telephone number table (step S10,
S11).

When the collation matches, the control device 14 regards the caller as the callee requested by the caller, and determines that the switch device 11 is the callee.
Then, the call path is connected so that the terminal 63 and the terminal 62 can talk (steps S12 and S17).

If the collation results are not matched, the control device 1 activates the announcement device 12 to make the terminal 6 of the callee.
After the announcement that the correct password has not been entered in 2, the call is disconnected (steps S12 and S1).
3). Further, the control device 14 activates the announcement device 12, and makes an announcement to the caller's terminal 63 to confirm the presence or absence of the message of the message and to accept the message if necessary (step S14).

When the control device 14 detects that there is a message via the receiver device 13, the control device 14 records (stores) the message in a storage medium (not shown in FIG. 2) in the announcement device 12. In this case, the announcement device 12 recognizes the recorded message,
The recipient's telephone number and the recipient's specific number are also stored, and if the sender's telephone number and the recipient's telephone number are known, the message (announcement) can be immediately retrieved using the telephone numbers as the keys (steps S15, S16).

If the caller does not specifically specify the called party, the called party specified service can be activated by dialing a number (eg, "0" or "#") that is not registered as the called party identification number. Instead, normal call processing is performed (steps S6 and S17).

Thereafter, when the caller corresponding to the callee identification number makes a call to the message reproduction telephone number "500" at the terminal 62, the control is performed when the receiver device 13 of the exchange 1 receives the call. It is passed to the control device 14. The control device 14 activates the announcement device 12 and announces the callee identification number and the password request to the caller's terminal 62 (step S21 in FIG. 4).

When the receiver device 13 of the exchange 1 receives the callee identification number and the password from the terminal 62, the control is passed to the control device 14. The control device 14 checks whether the password corresponding to the called party telephone number table matches the received password (steps S22 and S2).
3). When they match, the control device 14 determines that the announcement device 1
A message recorded using the callee telephone number and the callee identification number as keys is read from the recording medium in 2 and the message is sent to the caller's terminal 62 (step S25).
In this case, if the message is not recorded, the control device 14 (determines that it is not recorded according to the report from the announcement device 12) activates the announcement device 12 and confirms that there is no message recorded in the caller's terminal 62. Announce and disconnect. If the passwords do not match, the control device 14 activates the announcement device 12,
The terminal 62 is announced that the passwords do not match, and the terminal 62 is disconnected (step S26).

As described above, as shown in the callee telephone number table of FIG. 3, a plurality of callee identification numbers can be set for one callee telephone number, and a password can be set for each callee identification number. Therefore, it is possible to secure the privacy of a plurality of individual recipients with only one telephone.
Further, since it is confirmed that the caller is to specify the callee, it is possible to make a normal call, assuming that a call is made to a terminal that receives the callee specification service. Further, even if someone appears on the other party's terminal and the designated person is absent, the recorded message can be left and the designated person can listen to the recorded message later.

Next, the procedure for changing the password will be described. Now the telephone number is "03-444-555"
The description will be made assuming that the sender of the terminal 61 having "5" (the called party identification number is 1 and the current password is 1112: see FIG. 3) changes his password to "1113". In this case, it is assumed that the telephone number for which the password is changed is "501" for the service.

When the telephone number "501" is received from the terminal 61, the receiver 13 of the exchange 1 receives the control and transfers the control to the control device 14. Then, the control device 14 searches whether or not the caller's telephone number "0344445555" is registered in the called party telephone number column of the called party telephone number table of the storage unit 15 (step S31 in FIG. 5).

When the caller's telephone number is registered in the callee's telephone number table, the control device 14 controls the caller's terminal 6
The request for the called party identification number is announced to the terminal 1 (steps S32 and S33).

When the receiver 13 of the exchange 1 receives the called party identification number "1", the control is transferred to the control device 14. The control device 14 activates the announcement device 12,
Announces a password change request for the callee identification number "1" to the caller's terminal 61 (step S34,
S35).

When the receiver device 13 of the exchange 1 receives the change password “1113” from the terminal 61, the control is passed to the control device 14. The control device 14 searches the called party telephone table of the storage unit 15 using the called party telephone number and the called party identification number as keys, and sets the corresponding password to "1113".
Change to. That is, in FIG. 3, the password "1112" of the callee telephone number "03444555" and the callee identification number "1" is changed to "1113". When the change process is completed, the control device 14 causes the announcement device 12 to
And announces the completion of the change to the caller's terminal 61 and ends (steps S36, S37, S3).
8).

As described above, by changing the password from the contracted telephone (service holder),
Since you can change the password without going through the switch maintenance person,
The convenience can be increased, and it does not require the trouble of a switch maintenance person.

Further, in the above description, the case of making a call from a terminal under the control of another exchange that does not support the function of the present invention has been described. However, a call is made from a terminal under the same control that supports the function of the present invention. Even when the call is applied, the operation of the control unit 14 of the exchange 1 is the same as the operation described above. However, the area code is not entered when dialing off-hook from the terminal 61, but the control device 14
When searching the recipient's phone number table, it judges that the call is from a terminal under the same exchange because there is no area code, and automatically recognizes the called number with the area code "03" added. And search.

Therefore, even if the called party designation service of the first embodiment is not introduced to all the exchanges of the network, if the called side exchange supports the called party designation service, the service can be provided. it can. Needless to say, the effect can be further enhanced if the callee designation service is provided to a plurality or all of the exchanges of the communication network.

Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a block diagram of the entire system including the second embodiment of the present invention. Referring to the block diagram of the entire system of FIG. 6, the exchange 4, which performs the callee designation service, the terminals 81 and 82, and the line 9
1, 92. It should be noted that although there are a plurality of terminals, the number is two for convenience of explanation. Further, the communication network in this system includes the exchange 4, lines 91 and 92.

The exchange 4 has a switch device 41 for controlling a communication path between subscribers, an announcer device 42 for giving an announcement to the caller or the callee through the switch device 41, and a caller or callee for the caller through the switch device 41. Receiver device 4 for receiving dialed numbers
And a password corresponding to the telephone number and the called party identification number, and temporarily stores the called party telephone number and the called party identification number dialed by the caller.
And a control device 44 for controlling the switch device 41, the announcement device 42, the receiver device 43, and the storage device 45.

The storage unit 45 stores a called party telephone number table for requesting the called party to input a password. The called party telephone number table is composed of a called party telephone number indicating a called party's telephone number, a called party specific number corresponding to the called party, and a password corresponding to the called party. The storage unit 45 also has an area for temporarily storing the dialed incoming number and the called party identification number. The storage unit 45 is preferably a non-volatile memory or recording medium that retains its contents even when the power is turned off.

Next, the operation of the second embodiment of the present invention will be described with reference to FIGS. 3 and 6 to 7. In FIG. 6, as an example, it is assumed that the terminal 81, which is the caller, makes a call to the terminal 82, which is the callee. The telephone number of the terminal 82 is "03-444-7777" and the called party identification number is "1". The password is “9999”. These are shown in Figure 3 by the switch maintenance person when the service contract is made.
Is registered in the called party telephone number table of the storage unit 45.

The caller off-hooks the terminal 81, dials the telephone number "4447777" (for local calls, "03" is omitted), and subsequently dials the called party identification number "1". Upon receiving these via the switch device 41, the receiver device 43 of the exchange 4 passes control to the control device 44. Then, the control device 44 reads the called number telephone table of the storage device 45 and checks whether the called party telephone number and the called party specific number are registered in the called party telephone number table (step S61 in FIG. 7).

When the callee telephone number and the callee identification number are registered in the callee telephone number table, the control device 44 is operated.
Temporarily stores the callee telephone number and the callee identification number in the storage device 45, calls the terminal of the callee number as usual, and causes the caller to hear the call back tone (step S6).
2, S63).

When the called terminal 82 is off-hook,
The control device 44, which has detected the off-hook via the line 92 and the switch device 41, operates the announcement device 42, sends the announcement information to the terminal 82 through the switch device 41 and the line 92, and causes the callee to hear the password request announcement. In this case, the control device 44 retrieves the called party telephone number “4447777” from the called party telephone number table stored in the storage device 15, and determines the called party identification number “1”.
Is read and an announcement requesting a password corresponding to "1" is made to flow (step S65).

The called party on the terminal 62 side dials (inputs) the requested password. Receiver device 4 of exchange 4
3 receives this input password via the switch device 41 and passes control to the control device 44. Then, the control device 44 causes the password "777" corresponding to the callee telephone number "0344447777" and the callee identification number "1".
“8” is read from the incoming telephone number table stored in the storage device 45 and collated with the password dialed by the called party of the terminal 82 (steps S66 and S67).

When the collation results match, the control device 44 regards the caller as the callee requested by the caller, connects the call path with the switch device 41, and connects the terminals 61 and 6 to each other.
2 to be able to talk with each other (step S73).

If the collation results are not matched, the control device 44 informs the caller and the callee that the correct password has not been input, and then disconnects (steps S69 and S70). Further, the controller 44 is
The announcement device 42 is activated, and the caller's terminal confirms the presence or absence of a message for the message and, if necessary, announces that the message will be accepted (step S
70).

When the control device 44 detects that there is a message via the receiver device 43, the control device 44 records (stores) the message in a storage medium (not shown in FIG. 6) in the announcement device 42. In this case, the announcement device 42 identifies the recorded message so that it can be identified.
The recipient's telephone number and the recipient's specific number are also stored, and if the recipient's telephone number and the recipient's specific number are known, the message (announcement) can be immediately retrieved with the keys as keys (steps S71 and S72).

If the caller does not specify the called party, the called party specifying service can be operated by dialing a number (eg, "0" or "#") that is not registered as the called party identification number. Instead, normal call processing is performed (steps S62 and S73).

As described above, also in the second embodiment, as shown in the callee telephone number table of FIG. 3, a plurality of callee identification numbers are set for each callee telephone number.
Since a password can be set for each called party specific number, the privacy of a plurality of called parties can be secured with only one telephone. Further, since it is confirmed that the caller is to specify the callee, it is possible to make a normal call, assuming that a call is made to a terminal that receives the callee specification service. Further, even if someone appears on the other party's terminal and the designated party is absent, the recorded message can be left and the designated party can hear the recorded message later.

Further, the processing in the case of receiving the message reproduction number performs the same operation as the flowchart of FIG. 4 shown in the first embodiment of the present invention (the same operation will be obtained if the operation in FIG. 6 is replaced). Therefore, the description is omitted. Therefore, similar to the first embodiment, the effect that the information can be reliably transmitted is obtained.

Further, the password changing process performs the same operation as the flowchart of FIG. 5 shown in the first embodiment of the present invention (the same operation will be obtained if the operation in FIG. 6 is replaced), and therefore its explanation is omitted. . Therefore, similar to the second embodiment, it is possible to obtain the effect of being useful for improving convenience and maintenance. Needless to say, if the callee designation service shown in the second embodiment is adopted in a plurality or all of the exchanges of the communication network, further effects can be exhibited.
