DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication control apparatus for recognizing calling number information and calling subaddress information based on a call setup message and receiving a call to a specific type of extension terminal.

[0002]

2. Description of the Related Art Conventionally, when a call is received from an ISDN line, a method of receiving a call only to a specific type of terminal in a telephone device according to the contents of transmission capability information and higher layer compatibility information included in a call setup message is known. Are known.

On the other hand, when the transmitting side is an analog network or the like, the transmission capability information included in the call setup message at the time of the incoming call is 3.1 KHz audio, but the high-layer compatibility information may not exist. . In this case, it is necessary to perform an operation such as transferring the call to a facsimile (hereinafter referred to as a facsimile) when the responding person recognizes that the call is received from a facsimile (hereinafter referred to as a facsimile). Even in such a case, when it is known that there is only a specific communication from a specific caller, the identification number of the specific caller and the specific communication, for example, information such as G3 FAX are registered. This makes it possible to prevent an incoming call from a specific caller from being sent to an unnecessary terminal.

[0004]

However, in the above-mentioned conventional example, an incoming call from a caller in which information such as a specific identification number and a communication type is registered in advance is received by a specific terminal. However, when the content of the information is changed or added, it is necessary to register again, which is very inconvenient in operation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and at least in a communication control device capable of accommodating a voice communication device and a data communication device, at least a communication control device automatically registered according to caller information. An object of the present invention is to make a communication device of a communication type indicating voice communication and data communication receive an incoming call.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a communication control device capable of accommodating at least a voice communication device and a data communication device as extension terminals, and at least a voice communication or a data communication. Storage means for storing the type of communication corresponding to the caller information, a comparison means for comparing the caller information notified at the time of the incoming call with the registered caller information, and a comparison result by the comparison means If the caller information notified at the time of the incoming call is new, the caller information notified at the time of the incoming call and the type of communication are registered in the storage unit in correspondence with each other, and the comparison result by the comparing unit is If the caller information notified at the time of the incoming call has already been registered, the communication means registered in the storage means in association with the caller information notified at the time of the incoming call. It provides a communication control apparatus characterized by a control means for controlling so as to arrive at a type of communication device.

According to the above configuration, at least the type of communication indicating voice communication and data communication can be automatically registered for each caller information, and a communication device of a specific communication type responds to an incoming call from a specific caller. You can receive a call. For example,
Depending on the caller information, the call can be received by the telephone or by facsimile.

[0007]

FIG. 1 is a system configuration diagram of an example of a key telephone exchange according to a first embodiment. In FIG. 1, reference numeral 10 denotes a main unit of the key telephone exchange. In the main device 10, 1
1 is an exchange unit for exchanging communication paths, 12 is an ISDN / T point interface circuit for accommodating an ISDN line, 13
Is a dedicated telephone interface circuit for a dedicated telephone accommodated in the extension of the main unit 10, 14 is a general telephone interface circuit for accommodating a general telephone or a G3 facsimile, and 15 is a main storage unit for storing necessary information. Yes, a control storage unit 15a for storing the control programs of FIGS.
And a calling number table 15b for storing the type of communication and the like corresponding to the calling number. Reference numeral 16 denotes a main control unit that controls the entire main device 10.

Reference numeral 20 denotes an ISDN / T point interface 12
The receiving path from the exchange unit 11 to the exchange unit 11;
A transmission path to the DN / T point interface 12, a transmission path 22 from the exchange unit 11 to the dedicated telephone interface 13,
Reference numeral 23 denotes a reception path from the dedicated telephone interface 13 to the exchange unit 11, reference numeral 24 denotes a transmission path from the exchange unit 11 to the general telephone interface 14, and reference numeral 25 denotes a reception path from the general telephone interface 14 to the exchange unit 11. . Reference numeral 26 denotes a main control unit 16 which controls the interfaces 13 and 14 and the main storage unit 1.
A control bus for communicating control information and the like with the
7 is an ISDN line, 28 is a connection code for a dedicated telephone, 2
9 is G3 facsimile connection code, 30 is ISDN
The network 31 is one of the dedicated telephones connected to the connection cord 28.
Reference numeral 32 denotes one G3 facsimile connected to the connection cord 29.

In the above configuration, when an incoming call is received from the ISDN network 30, a call setup message is sent to the ISDN / T point interface 12 through the ISDN line 27. The ISDN / T point interface 12 that has received the call setting message sends the call setting message to the main controller 16 via the control bus 26. The main control unit 16 having received the call setting message determines whether the call is to be received by the dedicated telephone 31 or the G3 facsimile 32 based on the contents of the information in the call setting message. If it is not possible to decide on either one, the call is received by both or in accordance with the data setting or the like.

Next, an operation procedure of the main control unit 16 at the time of an incoming call will be described with reference to FIG. In step S21, the main control unit 16 having received the call setting message has an information transfer capability of 3.1 from the transmission capability information in the call setting message.
If it is KHz audio, the flow advances to step S22 to check whether or not the consistency information of the higher layer exists. If not, the flow advances to step S23 to check whether the destination number information or the destination sub address information exists. The process proceeds to step S25. If there is, it is determined in step S24 whether the incoming call is received from the destination number information or the destination subaddress information or the extension terminal can be specified. If not, the process proceeds to step S25.

[0011] At the time when step S25 is reached in the above flow, it has not been conventionally determined whether the call is to be received by the dedicated telephone or the G3 facsimile. I was taking the method that I had to do.

In this embodiment, it is checked whether or not the calling number information exists at the time of step S25, and if there is, the content thereof is temporarily stored in the main storage unit 15 in step S26, and further in step S27. Check whether the calling number is already registered. If it is not registered, no further determination is made, and the incoming call is made in a normal manner according to both the dedicated telephone and the G3 facsimile, or the data setting.

If it has been registered, step S28
The type of the communication is stored in the calling number table 15 of the main storage unit 15.
b, and if it is a telephone, it is sent to a dedicated telephone, and if it is a facsimile, it is received by a G3 facsimile. When the indefinite information is read out, the call is made to arrive at both the dedicated telephone and the G3 facsimile, or according to a data setting or the like by an ordinary method. If the terminal can be specified as a dedicated telephone or a G3 facsimile in steps S21, S22 and S24, the terminal is connected to the terminal specified according to the information as described in the conventional example.

Next, with reference to FIG. 3, a method of registering the type of communication at the end of a call will be described. The dedicated telephone interface 13 or the general telephone interface 14 that has received the disconnection signal of the dedicated telephone or the G3 facsimile sends the information to the main controller 16 via the control bus 26.

In step S31, the main control unit 16 having received the disconnection information checks whether the calling number temporarily stored in step S26 at the time of the incoming call is already registered in the main storage unit 15. Proceeds to step S32 to check whether or not the registered communication type is indefinite information. If the type is undetermined information, it is determined that registration is not necessary, and the process proceeds to the next disconnection recovery processing.

If the registered communication type is not indefinite information, it is checked in step S33 whether or not the type of the terminal that has sent the disconnection information matches the registered communication type. If they match, it is determined that there is no need to register, and the process proceeds to the next disconnection recovery process. If they do not match, the indefinite information is newly written in the main storage unit 15 in step S34, and then the process proceeds to the next disconnection recovery process. Step S31
If no calling number is registered in step S,
After registering the communication type together with the calling number based on the type of the terminal that has sent the disconnection information at 35, the process proceeds to the next disconnection recovery process.

[0017]

FIG. 4 is a flowchart showing a method of registering another communication type according to the present embodiment. In this example, when the information is undefined as in the above-described embodiment, the information that has already been registered is deleted without being registered. That is, it is checked in step S41 whether the calling number has already been registered. If the calling number has already been registered, the flow advances to step S42 to check whether or not the disconnection request terminal matches the registered communication type. Step S43
Cancel registration with. If they match, the process proceeds to the next disconnection recovery processing. On the other hand, if it is not registered in step S41, a new communication type is registered in step S44. According to this example, it is possible to cope with switching of the terminal on the transmission side.

Each piece of information in the call setting message includes not only independent information but also elements indicating the information. Further, in the above-described embodiment, the part called the calling number information is not limited to this, and may be the calling number information and the calling subaddress information. If it can be specified, only the originating sub-address information may be used. Further, in this embodiment, the calling number is registered at the time of disconnection, but it is obvious that the registration may be performed at the time of reception.

Further, in the embodiment of FIG. 1, only the ISDN line is accommodated, and only the dedicated telephone and the G3 facsimile are described as the accommodated extension terminals. However, it is needless to say that the present invention is not limited to this. It goes without saying that a private branch exchange may be used instead of the key telephone exchange.

The present invention may be applied to a system constituted by a plurality of devices or to an apparatus constituted by a single device. It is needless to say that the present invention can be applied to a case where the present invention is achieved by supplying a program to a system or an apparatus.

[0021]

As described above, according to the present invention,
At least the type of communication indicating voice communication and data communication can be automatically registered for each caller information, and an incoming call from a specific caller can be received by a communication device of a specific communication type. For example, a call can be received by a telephone or a facsimile according to the caller information.
