DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention Field of industrial application] relates message response connection method to connect distributed an incoming call in the private branch exchange to a predetermined line, in particular, connected to private branch exchange according to another registered on the source communication line class The present invention relates to a message answering connection method capable of connecting an incoming call first.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, this type of message response connection system responds to an incoming call to a private branch exchange 31 and transmits the responded incoming call to a terminal 2 accommodated in the private branch exchange 31. 3 is used to connect to the talker device 4 and the recording device 6 for responding to the message requested by the user.

Here, a conventional message response connection system will be described with reference to FIGS. 4 and 5. FIG. A private branch exchange 31 used in this type of message response connection system has a line circuit 11, a communication line switch 12, an external line trunk 13, a central processing unit 32, and a storage device 33, and the storage device 33 is a distribution service. It has a registration area 34. The line circuit 11 accommodates the terminals 2 and 3, the talker device 4, the recording device 6, and the like via a line, and is connected to the communication path switch 12. The telephone line switch 12 connects a line accommodated in the line circuit 11 and an external line trunk 13 accommodating the external line 8, and a mutual exchange connection inside the telephone line switch 12 is controlled by a central processing unit 32. Have been.
The storage device 33 stores and registers information necessary for controlling the central processing unit 32.

[0004] In a distribution service registration area 34 incorporated in the storage device 33, as shown in FIG. 5, a code for distributing a service to a desired one of a plurality of services is registered for each line accommodation position. Of the codes of this distribution service,
For example, the code 0 makes the distribution service unnecessary, and the other codes 1, 2,... (Other than the code 1 are not shown),
Can provide various distribution services. For example, code 1
At that time, I used the talker device 4 and the recording device 6 and said, "I'm so busy right now, but I'm sorry, but after a while, please call again. Please talk after the sound is finished. "And a recording device 6 for receiving the message of the other party.

[0005] This distribution service is used when the subscriber of the terminal 3 is busy and wants to avoid a call due to an incoming call for a while.
Used for etc. When the subscriber wants to receive the distribution service, the subscriber, for example, adds the designation number “4” for connecting the talker device 4 and the recording device 6 to the incoming call to the special number “16” for the distribution service, and “1”. The dial numbers are sent in the order of "" 6 "" 4 ". By this operation, the central processing unit 32
In response to the dial number “164”, the distribution service registration area 34 stores the location 10 of the line to which the terminal 3 is connected.
The code 1 is registered in the area 01. The confirmation of the end of the registration is not shown, but is notified by, for example, a synthesized voice. It is assumed that the deletion of the registration can be realized by, for example, a dial operation of the number “169” instead of the number “164”.

When an incoming call arrives at the terminal 3 in a state where the terminal 3 has been registered, the central processing unit 32 first searches the distribution service registration area 34 and distributes it from the area of the line accommodation position 1001 of the terminal 3. Extract the code 1 of the service. Since this code 1 means that registration is in progress, the central processing unit 32 controls the speech path switch 12 with this code 1, connects the talker 4 to the transmission path of the incoming call, and sets the reception path of the incoming call. , A recording device 6 can be connected to provide a message response service. As described above, in the above-mentioned distribution service, a desired message having the content according to the registration of the terminal is transmitted to all of the callers, that is, uniformly to the incoming call.

[0007] In the example shown in the figure, the terminal 2 at the accommodation position 1000 does not have the distribution service registered, so that the code 0 is recorded in the distribution service registration area 34 corresponding to the line accommodation position 1000. I have. When there is an incoming call to the terminal 2, the central processing unit 32 performs a normal connection process.

[0008]

According to the above-described conventional message answering and connecting method, when a terminal wants to avoid a call due to an incoming call, for example, the terminal registers a predetermined code by dial operation to send the incoming call to the source of the incoming call. It has a configuration in which a desired message is transmitted and a message is received from a transmission source. With this configuration, even for an incoming call from a specific caller, such as an outside line call from an important customer or a call from a specific key person with an urgent requirement, only the message reply processing of the same message can be performed. There is.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a message answering connection system in which a private branch exchange can provide an emergency or important incoming call from a specific caller while distinguishing it from a normal incoming call.

[0010]

A message response connection system according to the present invention is directed to a message response connection system in which a private branch exchange distributes an incoming call to a predetermined line. In the message response connection system, the private branch exchange distributes the incoming call. determine the calling line classes for sorting for each destination that connects Te, and calling line class registration area registering in advance assigned the outgoing line classes for each communication line and distributed an incoming call by the calling line classes registered A distribution service registration area for registering the validity / invalidity of the distribution service to be connected for each communication line, and when an incoming call is received on a communication line registered in the distribution service registration area, transmission of the incoming call The source line class registered in the source communication line area based on the source communication line is taken out from the source line class registration area, and is applied to the connection destination line specified in the taken out source line class. Connecting the incoming call. Also, for an outside line connected to another exchange, a predetermined outgoing line class is assigned to the outside line as a source communication line and registered in the outgoing line class registration area.

Further, as another means, an external line connecting the exchanges has a destination address, and a call setting signal for requesting the call setting includes the calling line class. When receiving an incoming call from, read the calling line class from the call setting signal included in the incoming call,
The incoming call is connected to the connection destination line specified in the read outgoing line class.

[0012]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the message response connection system shown in FIG. 1, the storage device 15 of the private branch exchange 1 is provided with an outgoing line class registration area 17 in addition to the distribution service registration area 16.
It differs from the message response connection system shown in FIG. 4 in that a control operation of the central processing unit 14 for the transmission line class registration area 17 is added.

As in the case of FIG. 4, the private branch exchange 1 includes a line circuit 11, a speech path switch 12, and an outside trunk 1.
3 and a central processing unit 14, and the storage device 1
5 is provided with the distribution service registration area 16 and the transmission line class registration area 17 as described above.

The line circuit 11 accommodates the terminals 2 and 3, the talkers 4 and 5, and the recording devices 6 and 7 via lines, and is connected to the communication path switch 12. The communication path switch 12 accommodates a line accommodated in the line circuit 11 and an external trunk 13 accommodating the external line 8, and the exchange connection inside the communication path switch 12 is performed by the central processing unit 1.
The storage device 15 also stores and registers information necessary for controlling the central processing unit 14.

As shown in FIG. 2, the distribution service registration area 16 and the outgoing line class registration area 17 provided in the storage device 15 correspond to the urgency and importance of communication for each line accommodation position. A distribution service for distributing incoming calls and a transmission line class are registered.

In FIG. 2, the line accommodation positions 1000, 100
The codes 0, 1, 0, 1 are registered in the distribution service registration area 16 corresponding to each of 1, 1002, 1003, and the codes 1, 1,.
2, 2 are registered. Distribution service registration area 16
The sign 0 means that the service registration is invalid, and the sign 1 means that the service registration is valid. Further, reference numeral 1 in the transmission line class registration area 17 indicates that the first distribution service is performed, and reference numeral 2 indicates that the second distribution service is performed. The first and second distribution services will be described later.

In this example, at the time of registration in the distribution service registration area 16, reference numeral 0 is a code indicating that service registration is invalid. The registration of the code 1 is performed by the terminal (for example) 3 requesting the registration, for example, the special number “160” for the distribution service.
Is performed by dialing. By this number operation, the central processing unit 14 sets the line accommodation position 10 of the line to which the terminal 3 is connected in the distribution service registration area 16.
The code 1 is stored and registered in the area 03. In this registration, for example, the special number “169” is used instead of the special number “160”.
It can be deleted by the dial operation of. Confirmation of these registrations and deletions is possible with conventional equipment and procedures.

Registration in the transmission line class registration area 17 and deletion of the registration are performed in advance by a predetermined operation from a maintenance console of the private branch exchange 1 or a master terminal connected to the master line.

The first distribution service by reference numeral 1 in the outgoing line class registration area 17 is an outside line telephone from an important customer,
Registered for incoming calls from specific callers, such as urgent requirements calls from specific key persons. Line capacity 1000
In the case where an outside line is connected to the terminal and a terminal of the president is connected to the line accommodation position 1001, as shown in FIG. 2, reference numeral 1 is registered in the area of the transmission line class. In this state, the line accommodation position 10 having the transmission line class of code 1
Outgoing calls from the lines 00 and 1001 can be received at any receiving terminal regardless of the validity / invalidity of service registration at the receiving terminal.

The second distribution service using the code 2 in the outgoing line class registration area 17 corresponds to, for example, the talkie apparatus 5 for transmitting the same message as a normal answering machine, and the terminals 2, 3,. Recording devices 6, 7,... For receiving the message of the other party are provided.

A call originating from a terminal (for example) 2 of the line of the code 2 in the line accommodation position 1002 shown in FIG. 2 arrives at the terminal 3 of the effective line accommodation position 1003 registered with the service. In this case, the terminal 2 of the caller is connected to the talker device 5 corresponding to the second distribution service and the recording device 7 corresponding to the terminal 3 of the incoming call, instead of the terminal 3 of the incoming call destination by the dial number. This operation procedure will be described later.

In this example, description has been given of the second distribution service by reference numeral 2. However, the third and subsequent distribution services are also provided. Response message can be provided. Furthermore, for a transmission line class having a low degree of urgency and importance, a distribution service for eliminating connection to a recording device only by guidance by a talker device can be provided.

Next, the main operation of the central processing unit 14 will be described with reference to FIG. 3 and FIG. 1 and FIG. First, when the central processing unit 14 of the private branch exchange 1 receives an incoming call (procedure 21), it identifies the line accommodation positions of the outgoing line and the incoming line (procedure 22). Next, the central processing unit 14 searches the distribution service registration area 16 of the storage device 15 and checks whether or not the distribution service is registered (step 23).

If the result of step 23 is YES and the code is 1 in the distribution service registration area 16, the calling line class is read from the line accommodation position of the calling line identified in step 22 (step 24).
You. For example, if an incoming call is received from an outside line and this outside line is connected to the line accommodation position 1000, the read outgoing line class is code 1 (YES in step 25), and the central processing unit 14 performs a normal incoming connection operation ( Performing step 26),
Connect the outgoing line to the destination terminal requested by the source.
On the other hand, when the procedure 23 is NO and the code is 0 in the distribution service registration area 16, the normal incoming connection of the procedure 26 is performed.

As described above, for example, when a call is originated from the terminal 2 connected to the line accommodating position 1002, the read out transmission line class is code 2 (N in step 25).
O). When this incoming call arrives at the terminal 3 connected to the line accommodation position 1003, the central processing unit 14
Controls the speech path switch 12 to provide the message answering service of code 2. As a result, the terminal 2
Is connected to a talker device 5 corresponding to the class code 2 of the transmission line, and a recording device 7 corresponding to the destination terminal 3 is connected to the reception line. provide. As a result, the terminal 3 can listen to the recording of the message by the distribution service from the recording device 7 by using a facility using a known technique and performing a predetermined dial operation.

The talker and the recorder described with reference to FIG. 1 are housed and connected to the line circuit of the private branch exchange,
It is connected to the central processing unit via a line circuit,
Like the trunk, it may be directly connected to the central processing unit and directly connected to the central processing unit. Also, although the talk apparatus is illustrated and described with blocks divided for each message, and the recording apparatus is illustrated and described with blocks divided for each terminal, the apparatuses can be collectively installed by performing address control on a disk.

In the connection between exchanges using an external line, this kind of outgoing line class is encoded by a common line signaling method into a message format applied to the call setting of the basic call control sequence specified by ISDN. By including them, the same function as described above can be exerted. In this case, for an outgoing call to an external line, the central processing unit sends out a call setting message including the outgoing line class of the outgoing line in a predetermined portion of the message format. On the other hand, for an incoming call from an outside line, the central processing unit takes out the calling line class from a predetermined portion of the call setting message instead of the calling line class registration area of the storage device and uses it for connection control.

[0029]

According to the present invention as described above,
The private branch exchange determines the outgoing line class for distribution for each connection destination to which incoming calls are to be connected, and assigns this outgoing line class to each communication line and pre-registers it.
