Description

Description: TECHNICAL FIELD The present invention relates to a communication device that notifies a user of a communication terminal when the user of the communication terminal receives an incoming call when the user is absent.

[Prior Art] For example, a voice terminal device (telephone terminal) using a line network
When carrying out a conversation with the other party, if the other party is absent, naturally the conversation with the other party cannot be established.

When the conversation with the other party is not established in this way, for example, if the other person can share the telephone terminal used by the other party and the other person can take the telephone terminal, Since the message can be requested to the other party of the conversation, the conversation intended by the caller can be performed. Further, when the other person responds to the caller with the time when the other party of the conversation comes back, a call can be made again after that time so that the conversation with the intended other party can be performed.

However, it is inconvenient because a person other than the person who is the purpose of the caller has to talk to the caller, so that a person who does not need to talk to the caller may be interrupted from work.

In addition, when the other party of the conversation is using the telephone terminal exclusively, it is not convenient for the caller because he / she cannot even request a message from another person.

By the way, in recent years, the functions of the private branch exchange have become extremely rich, and in the case of a call between extension lines, when the other party is absent, it is displayed on the other party's telephone terminal that there is an incoming call. , Some have a function of automatically connecting to the caller's telephone terminal when the other party returns.

With such a function, even if the telephone terminal is a dedicated one, it is very convenient because it automatically connects to the other party who came when he / she was absent.

However, in the case where the other party is automatically connected to the other party when he / she is absent, it is impossible to identify the other party when the telephone terminal is shared by multiple people, so the conversation intended by the caller cannot be performed. It cannot be done, which is not preferable. Further, even if the telephone terminal is a dedicated one, it is not possible to confirm who came from when the user was absent, which is not desirable.

[Purpose] The present invention has been made to solve the above-described inconveniences of the related art, and can reliably perform communication intended by a caller, and can be performed by other people who are not involved in the communication. The object is to provide a communication device that does not bother.

[Configuration] According to the present invention, when a user of a communication terminal is absent, a communication device for notifying the user when there is an incoming call indicates that the user of the communication terminal is absent. Absence information registration means for registering information, and when an incoming call is received when the absence information is registered in the absence information registration means, a caller name and a telephone number are requested to the sender of the call. Data requesting means, caller information storage means for saving the caller name and telephone number notified by the caller by the request of the data requesting means, and the caller information when the user gives a predetermined instruction. The caller means is provided for taking out the caller name from the storing means and notifying the user of the caller, taking out the telephone number from the caller information storing means, and making a call to the telephone number. .

The line circuit 3 also has the same configuration as the line circuit LC ₁ .

Now, the control unit 4 in the private branch exchange PBX manages various information used for the electronic telephone directory function in the formats shown in FIGS. 4 (a) to 4 (e).

Of these information, the personal information ID is the private branch exchange PBX.
The extension management table TI is information indicating the usage status of the multifunction telephone terminals FT _{1 to} FT _{n on} the extension.

The personal information ID is the personal name DN of the person, the DO to which the person belongs, the telephone number (in this case, the extension number) TN, the fax number FN that indicates the extension number of the nearest facsimile machine, the extension number of the temporary destination (or the extension number). Number) for temporary phone number T
It consists of T, the presence / absence data SN that shows whether you are in your seat, the available time AB that shows the time zone when you can receive a call, and the incoming call information CD that shows that there was an incoming call when you were absent.
It is stored in the storage device 6. The control unit 4 appropriately reads the data from the storage device 6.

The personal name DN is a personal name DNd that is a direct expression consisting of a sequence of characters (kanji, kana, numbers, alphabets, symbols, etc.) and the alphabet of the characters that form the name in the following order. It consists of the personal name DNm of the indirect expression obtained when it is converted to a number by the method.

The code information forming this indirect expression is assigned the alphabet in each number of the push dial (for example, the numeric keypad of the multi-functional telephone terminal devices FT _{1 to} FT _n ) in correspondence as shown in FIG. It is a coded number string when the constituent alphabets are selected in that order.

That is, for example, the last name "Furukawa" is "FURUKAWA"
Since it is written in Roman letters, it is converted into a number string "38785292" according to the above-mentioned method of assigning alphabets and numbers, and this is stored as a personal name DNm.

The affiliation DO also belongs to the direct expression affiliation DOd and the indirect expression affiliation D.
It consists of Om.

As the data of indirect expression, in the case of individual name DNm, the employee number set in the company etc. can be used for the individual, and in the case of belonging DOm, the identification set in the company A number or the like can be used.

The incoming call information CD is a series of data that includes caller information, caller telephone number, and valid / invalid information for each incoming call for all incoming calls.

The extension management table TI is provided for each multifunction telephone terminal FT.
_{For 1 to} FT _n , it stores individual / multiple information that indicates whether it is being used by an individual or by multiple people. If it is being used by an individual, information indicating the name and Affiliation information representing the affiliation is stored as a direct expression. As the terminal identification information, data representing the type of each multifunction telephone terminal FT _{1 to} FT _n is stored.

In addition, of personal information ID, temporary telephone number TT and
Data other than the absent data SN is directly formed (registered) from the administrator terminal device 2 and is not updated or deleted unless a special password set in the system is input. At the time of registration, the temporary telephone number TT field is set to an invalid state (for example, all digits are FF (hexadecimal number)), and the presence / absence data SN is set to the “present” state. In addition, the password may be set for each individual, and in that case, the personal information ID regarding the user can be arbitrarily updated by himself.

Further, like the temporary telephone number TT for the telephone number TN, a temporary fax number for the fax number FN can be set.

Similarly, the extension management table TI is also directly registered by the administrator terminal device 2.

With the above configuration, when calling from the multifunction telephone terminal FT ₁ to a desired destination, for example, the operator first inputs the personal name of the recipient by indirect expression from the numeric keypad of the multifunction telephone terminal FT ₁ , and then the phone book key. Turn on.

As a result, the multifunction telephone terminal FT ₁ is connected to the line circuit LC ₁ and transmits the DTMF tone signal corresponding to the telephone directory key by the dialer 13 and the inputted personal name via the modem 14. After transmitting the personal name, the network control device 11 is switched to the handset 12 side.

In the line circuit LC ₁ , in the initial state, the switch 24 is connected to the switch 25 side and the switch 25 is connected to the modem 23 side, respectively, and the DTMF tones sent from the multifunction telephone terminal FT ₁ are those of the telephone book key. Switch 25
Switch to the switch 24 side, and after that the multifunction telephone terminal
The personal name information output from FT _{1 is} output to the terminal control unit 5, and then the switch 25 is switched to the modem 23 side.

The terminal control unit 5 transfers the personal name information output from the line circuit LC ₁ to the control unit 4.

The control unit 4 stores the personal information ID in which the personal name DNm of the same indirect expression as the transferred personal name of the indirect expression is registered based on the information of the personal name transferred from the terminal control unit 5. Search and read from. Next, it is determined whether or not the presence / absence data SN of the read personal information ID is set to the presence state, and when it is set to the presence state, it is further shown in the callable time AB. Judge whether it is a time zone when the call can be received.

If the destination is ready for incoming calls, personal destination information CD
It determines whether valid data is stored in the temporary telephone number TT of the user, and if the temporary telephone number TT is valid, the temporary telephone number TT is used. If the temporary telephone number TT is invalid, the telephone number TN is used. reading, respectively, with instructions to to notify that it is possible outgoing multifunctional telephone terminal FT ₁ to the terminal control unit 5, the multi-function telephone by speech path 1 terminal FT ₁
Is connected to the extension of the temporary telephone number TT or the telephone number TN read out. Further, the terminal control unit 5 is instructed to connect the extension corresponding to the temporary telephone number TT or the telephone number TN read at that time to the communication path 1.

As a result, the terminal control unit 5 notifies the line circuit LC ₁ to connect the multifunction telephone terminal FT ₁ to the communication path 1, and also the line circuit LC ₂ corresponding to the extension of the destination designated by the control unit 4. ~ Instruct LC _n to connect to speech path 1.

As a result, the line circuit LC ₁ switches the switch 24 to the communication path 1
And the switch 25 is switched and connected to the model 23 side, so that the multifunction telephone terminal FT ₁ is connected to the communication path 1.

On the other hand, the line circuits LC _{2 to} LC _{n of} the destination extension are
Is switched to the side of the communication path 1 so that the multifunction telephone terminals FT _{2 to} FT _{n of the} destination are also connected to the communication path 1 and, as a result, can be connected to the destination telephone terminal to make a call.

If the destination cannot receive the call, the control unit 4 instructs the terminal control unit 5 to connect the multifunction telephone terminal FT ₁ to the communication path 1, and the communication path 1 causes the line circuit LC ₁ to operate. The voice response device 7 is connected.

As a result, the terminal control unit 5 notifies the multifunction telephone terminal FT ₁ to connect to the communication path 1, whereby the line circuit LC ₁ switches and connects the switch 24 to the communication path 1 side.
As a result, the voice response device 7 and the multifunction telephone terminal FT ₁ are connected via the communication path 1. At this time, the modem 23 of the line circuit LC ₁ remains connected to the terminal control unit 5.

In this state, the control unit 4 sends the voice response device 7 to the operator of the multifunction telephone terminal FT ₁ , for example, a voice message “The designated destination is absent.”.

At this time, the contents of the extension management table TI of the multifunction telephone terminal FT ₁ used by the caller are referred to, and if the multifunction telephone terminal FT ₁ is for personal use, the extension management is performed. The name information of table TI is stored in the caller information field of the incoming call information CD of the personal information ID of the destination, and the extension number of the multifunction telephone terminal FT ₁ is also stored in the caller phone number field, and the corresponding valid / valid Set invalid information to valid state.

When the multi-functional telephone terminal FT ₁ is used by a plurality of persons, the voice response device 7 sends a voice message, for example, "Please input your personal name and telephone number."

As a result, DTMF tones are output from the multifunction telephone terminal FT _{1 in} the order of the keys operated by the operator,
The line circuit LC ₁ is discriminated by the control unit 22 and converted into corresponding code information, and this code information is output to the terminal control unit 5 via the modem 23 and further transferred to the control unit 4.

Thereby, the control unit 4 stores the transferred personal name and telephone number in the caller information column and the caller telephone number column of the incoming call information CD of the personal information ID of the destination, and the corresponding valid / invalid information. To enable state.

At this time, the personal information ID having the same personal name DNm as the indirect expression as the notified personal name is searched and read from the storage device 6, and the personal name DNd of the direct expression of the personal information ID is
You may make it memorize | store in the column of the sender information of the incoming call information CD of personal information ID of a destination.

When the setting of the incoming call information CD is completed in this way, the control unit 4 instructs the call path 1 to disconnect the line circuit LC ₁ and the voice response device 7, and the terminal control unit 5 also. Command LC ₁ to disconnect from channel 1.

As a result, the terminal control unit 5 notifies the line circuit LC ₁ to disconnect the multifunction telephone terminal FT ₁ from the communication path 1, whereby the line circuit LC ₁ switches the switch 24 to the switch 25 side and connects it.

In addition, the control unit 4 instructs the terminal control unit 5 to notify the destination at this time that there is an incoming call.

Thereby, the terminal control unit 5 instructs the line circuits LC _{2 to} LC _n corresponding to the extension of the destination specified by the control unit 4 to switch the multifunction telephone terminals FT _{2 to} FT _n to the terminal control unit 5 side. Then, any one of the line circuits LC _{2 to} LC _n switches and connects the switch 25 to the switch 24 side to connect the multifunction telephone terminals FT _{2 to} FT _n to the terminal control unit 5.

In this state, the terminal control unit 5 controls the multifunction telephone terminals FT _{2 to} FT _n.
Notification that there was a missed incoming call with respect to which the multifunctional telephone terminal FT ₂ ~FT _n displays that there was a missed incoming call. For example, a lamp for displaying an incoming call is absent.

In this manner, when the destination is absent, together with that an incoming call is displayed on the multifunction telephone terminal _{FT 2 ~FT n (FT 1 ~FT} n), incoming call information of the personal information ID of the destination Information about the caller is stored in the CD column. Further, when there are incoming calls from a plurality of callers, information about each caller is stored in the column of the incoming call information CD of the personal information ID of the destination.

Then, when the destination person was absent came back, when it is displayed that there was a missed incoming calls to the multi-function telephone terminal FT ₂ ~FT _n that the person is using, first, the multi-function telephone terminal FT ₂
~ Pick up the handset 12 of FT _n , turn on the phonebook key, and enter your personal name.

As a result, the control unit 4 is notified of the personal name in the same manner as described above. Then, the control unit 4, first, a command and to connect the multi-function telephone terminal FT ₂ ~FT _n and voice response unit 7 to the communication path 1, the multi-function telephone terminal by the terminal control unit 5 in a similar manner as described above Connect FT _{2 to} FT _n to communication path 1.

Next, the control unit 4 sets the personal information corresponding to the received personal name.
The ID is retrieved from the storage device 6 and read out, and the personal information ID
The valid caller information is output from the column of the incoming call information CD to the voice response device 7, and the personal name of the caller is notified to the recipient by voice. At this time, the personal information ID is set to the presence / absence information SN.

Then, when this notification is completed, the call path 1 is switched from the voice response device 7 to the extension corresponding to the caller telephone number corresponding to the caller information, and the call connection state is established. Is called automatically.

In addition, at this time, after notifying the caller's personal name by voice, for example, a voice message "Do you want to connect to the caller? When connecting, enter dial 1 and when not connecting, enter dial 2." It is also possible to send the caller to the addressee and automatically call the caller from the addressee only when the dial 1 is operated.

In this way, when the addressee and the caller are automatically called, the valid / invalid information regarding the caller connected at that time is set as invalid information.

Then, when the call from the addressee to one caller ends, if valid caller information is stored in the field of the incoming call information CD for that addressee, the same process as above is executed for that caller information. In this way, all the callers who are out of the office are automatically called by the recipient.

Next, a case where the operator updates the personal information ID about himself will be described.

For example, considering updating from the multi-function telephone terminal FT ₁ , the operator first turns on the telephone book operation key and then the telephone book key.

As a result, the multifunction telephone terminal FT ₁ is connected to the control unit 4 via the line circuit LC ₁ and the terminal control unit 8 in the same manner as described above. Next, the multifunction telephone terminal FT ₁ is connected to the network control device 11
Is switched to the modem 14 side, a terminal command is transmitted to the control unit 4 via the modem 14, and thereafter the control unit 4
The data input from the operation keys is transferred to the control unit 4, and the response data or the echo back data from the control unit 4 is displayed on the display. When operating as a terminal device of the control unit 4 as described above, data is exchanged between the multifunction telephone terminal FT ₁ and the control unit 4 via the modem 14.

When the terminal command is transferred from the multifunction telephone terminal FT ₁ , the control unit 4 first requests to input the personal name of the operator by indirect expression, and when it is input, the input indirect expression is input. Indirect expression personal name DNm
Is searched from the storage device 6 for the personal information ID in which is registered,
The personal information ID is read into the memory 2.

At this time, it is also possible to request that the affiliation be further input by indirect expression. Further, when a password is set for an individual, it is possible to request the input of the password immediately after the input of the personal name by the indirect expression, and display the operation menu only when the correct password is input. If the correct password is entered at that time, the line may be disconnected at that time.

Then, for example, "1. presence / absence change 2. temporary number input 3. Other, 4. Exit" to display the operation of the menu to the multi-function telephone terminal FT _1, to select the desired operation to the operator.

Here, if the operator selects "1. presence / absence change", first, the control unit 4 displays the present / present presence / absence data SN and asks the operator whether to change. On the other hand, when the operator inputs a change (for example, turning on the numeric keypad "1"), the content of the presence / absence data SN is changed, the result is displayed, and the operator is asked to confirm it. Then, the first operation menu is displayed. At this time, if the presence / absence data SN is changed from the “absence” state to the “present” state,
The control unit 4 changes the valid temporary telephone number TT to the invalid state.

When the operator selects "2. Temporary telephone number input", the temporary telephone number input mode is set, and the key data entered by the operator from the operation keys is temporarily stored as a temporary telephone number and the input data is echoed. Back. Then, when the operator notifies the end of the temporary telephone number input, the data input so far is stored as the temporary telephone number TT in the personal information ID, and the first operation menu is displayed.

Normally, when the presence / absence data SN is changed from “present” to “absent”, this temporary telephone number is also entered. In addition,
As the temporary telephone number, the telephone number of the speed dial set in the multifunction telephone terminal FT ₁ can be entered, and either an extension number or an outside line number can be input.

If you select "3. Other" in the operation menu, the mode for changing the contents of other personal information IDs will be selected.
The control unit 4 first requests the input of the password set in the system (or the password set for an individual).

If a correct password is entered here, the control unit 4
Displays a submenu for selecting the item to change. Then, when one item is selected from that submenu, the contents currently set for that item are displayed, and a question is asked as to whether or not to change, and if so, move to the work for changing and change. When is completed and is not changed, the submenu is displayed.

This submenu includes an item for ending the work of “3. Others”, and when it is completed, the first operation menu is displayed. Also, when the correct password is not input before displaying the sub menu, the display returns to the first operation menu display state.

Then, bother "4. End" is selected from the operation menu, the control unit 4 terminates the operation mode, and at the same time to return the multi-function telephone terminal FT ₁ to the original state, multi by end control section 5 Function Disconnects from the telephone terminal FT ₁ .

As for the contents of the operation menu other than this, for example, if the personal information ID includes a temporary fax number, you can add an item to enter this temporary fax number, and in that case, the presence / absence data SN is "absent" to "present"
When the status is changed, the temporary fax number may be automatically set to the invalid status. Also, of course, personal information
The operation procedure for updating the ID is not limited to the above.

Although the individual information ID can be deleted by each individual, the individual information ID may be deleted only by the administrator terminal device 2 as at the time of registration.

By the way, in the embodiment described above, the private branch exchange device
Although the function of the electronic telephone directory is realized as one of the functions of the PBX, the function of this electronic telephone directory can be realized by a separate device.

 Next, another embodiment of the present invention will be described.

FIG. 6 is a schematic diagram of a private branch exchange device to which an electronic telephone directory device according to another embodiment of the present invention is applied.
In the figure, the same parts as those in FIG. 1 and corresponding parts are designated by the same reference numerals, and the description thereof will be omitted.

In the figure, the private branch exchange PBXa has its outside line side connected to a public network (subscriber network) via a line PL.

A plurality of multifunction telephone terminals FT _{1 to} FT _n and an electronic telephone directory device BK are connected to the extension.

Therefore, the private branch exchange PBX connects each terminal device connected to the extension line to each other, and also connects each terminal device connected to the extension line to the line PL which is an outside line.

The electronic telephone directory device BK is connected to the private branch exchange device PBXa via a plurality of extensions, and the administrator terminal device 2 and the relay stand 9 are also connected to this electronic telephone directory device BK. Shown in Figure 2.

In the figure, a CPU (central processing unit) 31 is for controlling the electronic telephone directory device BK, and stores a memory 32 constituting a system memory or a work memory, and control data and various file data. The magnetic storage device 33 for storing the CPU 31, the memory 32, and the magnetic storage device 33 are connected via a system bus SB.

Further, the administrator terminal device 2 and the relay stand 9 are connected to the interface circuits 34 and 35 system buses SB.

In addition, the extension of the private branch exchange PBXa is equipped with a multifunction telephone terminal.
FT _{1 to} FT _n are connected via communication control units CF _{1 to} CF _n , and these communication control units CF _{1 to} CF _n are connected to the system bus via interface circuits IF _{1 to} IF _n. Connected to SB.

FIG. 8 shows an example of the communication control units CF _{1 to} CF _n .

In the figure, a communication control unit CF ₁ (to CF _n ) is a push output from a network control device 41 and a multifunction telephone terminal FT _{1 to} FT _n having an automatic call-in / out function for connecting to a private branch exchange PBXa. DTFM detector 42 for detecting a dial tone multi-function telephone terminal FT ₁ ~FT _n and modem 43 for exchanging data, a message from the CPU31 respect multifunction telephone terminal FT ₁ ~FT _n voice A voice synthesizing unit 44 for outputting, a network control device 41, a DTMF detecting unit 42, a control unit 45 for controlling the modem 43 and the voice synthesizing unit 44, and for exchanging data between the control unit 44 and the CPU 31. Interface circuit
It consists of 46.

Therefore, the communication control units CF _{1 to} CF _n are selected by the private branch exchange PBXa when originating from the multifunction telephone terminals FT _{1 to} FT _n and connected to the electronic telephone directory BK from the private branch exchange PBXa.

This is an application of the group transfer function of the private branch exchange PBXa, that is, the private branch exchange PBXa is previously configured so that a plurality of extensions connected to the communication control units CF _{1 to} CF _n form one group. be registered, from the multi-function telephone terminal FT ₁ ~FT _n, simply by specifying the extension number associated to a group of the communication control unit CF ₁ ~CF _n the private branch exchange device PBXa, the communication control unit CF ₁ The empty one of CF _n is automatically selected and connected by the private branch exchange PBXa.

In the above configuration, for example, from one of the multi-function telephone terminal FT ₁ ~FT _n (in this case be from multifunctional telephone terminal FT ₁₎ when sending to a desired destination, the operator may first multifunctional telephone terminal FT ₁ Enter the personal name of the recipient by indirect expression using the numeric keypad of and then turn on the phonebook key.

As a result, the multifunction telephone terminal FT ₁ is
And sends the extension numbers corresponding to the groups of the communication control units CF _{1 to} CF _n . Accordingly, the private branch exchange device PBXa looks for one of the vacant communication control unit CF _{1 ~CF n,} to connect the multi-function telephone terminal FT ₁ on its _{1 ~CF n.}

When the connection with the communication control units CF _{1 to} CF _n is completed, the multi-function telephone terminal FT ₁ switches the network control device 11 to the modem 14 side, and the indirect expression personal name input by the operator is given a connection request command (predetermined). (Consisting of the code information of 1), and is sent to the electronic telephone directory device BK via the modem 14.

As a result, the electronic telephone directory device BK first identifies the connection request instruction code included in the received data, and determines that the data that follows is a personal name for indirect expression.

Then, the personal information ID in which the personal name DNm of the indirect expression same as the transferred personal name of the indirect expression is registered is searched from the magnetic storage device 33, and the personal information ID is read out to the memory 32. Next, it is determined whether or not the presence / absence data SN of the read personal information ID is set to the presence state, and when it is set to the presence state, it is further shown in the callable time AB. Judge whether it is a time zone when the call can be received.

If the destination is ready to receive a call, it is determined whether or not valid data is stored in the temporary telephone number TT of the personal information ID, and if the temporary telephone number TT is valid, the temporary telephone number TT, or When the temporary telephone number TT is invalid, the telephone number TN is read out, and the private branch exchange PBXa is instructed to connect the multifunction telephone terminal FT ₁ to the read temporary telephone number TT or telephone number TN. At the same time,

As a result, the private branch exchange PBXa becomes a multifunction telephone terminal FT ₁
And the electronic telephone directory device BK are disconnected, the multifunction telephone terminal FT ₁ is put on hold at the same time and the multifunction telephone terminal F
T _{1 is connected} to the temporary telephone number TT or the multifunction telephone terminals FT _{2 to} FT _n corresponding to the telephone number TN. In addition, the multifunction telephone terminal FT ₁ switches the network control device 11 to the handset 12 side in accordance with a command from the electronic telephone directory device BK, so that the designated individual can talk.

If the destination cannot receive the call, CPU31
While instructing the multifunction telephone terminal FT ₁ to switch to the handset 12 side, the voice synthesis unit 44 of the communication control units CF _{1 to} CF _n instructs the operator of the multifunction telephone terminal FT ₁ to, for example, “designate. The recipient is absent. "

Then, similarly to the above-described embodiment, the personal name and telephone number of the caller are stored in the caller information column and the caller telephone number column of the incoming call information CD of the personal information ID of the destination, and the corresponding valid / Set invalid information to valid state.

However, in this case, when the multi-functional telephone terminal FT ₁ is used by a plurality of people, in response to a voice message such as “Please input your personal name and telephone number” output from the voice synthesis unit 44, The DTMF tones output from the multifunction telephone terminal FT ₁ corresponding to the order of the keys operated by the operator are detected by the DTMF detection units 42 of the communication control units CF _{1 to} CF _{n and} are determined by the control unit 45, and the CPU 31 is determined. Be notified.

After setting the incoming call information CD in this way, CPU3
