DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile
And service setting method in facsimile communication,
In particular, the service provider side of facsimile communication (immediate
In other words, the user side (ie, the terminal device)
Side) to temporarily provide services that can be received
The present invention relates to a facsimile apparatus capable of stopping at a time.

[0002]

2. Description of the Related Art Conventionally, services are provided based on a service contract or the like between a user and an exchange. In this case, as a typical service function, for example, when there is an incoming call from a third party on a line during a call, such as an interrupt call or call waiting, a notification to that effect is given with a specific tone,
In some cases, the original line is temporarily held to connect the line to a third party. In this case, such a service function cannot be controlled so as to be temporarily provided and stopped according to the convenience of the terminal device on the user side.

[0003]

For example, in a system in which the same telephone number is used for a telephone which is a general terminal device and a facsimile device, when a user uses a telephone,
In a case where a service for notifying a user of a call request from a third party is contracted, a communication error occurs if the service is provided while the facsimile apparatus is communicating. This is because the services that can be enjoyed differ depending on the type of the terminal device. On the other hand, when the composite terminal device is used, a service that interferes with the predetermined operation mode cannot be contracted. Further, such a service function cannot be controlled so as to be temporarily provided and stopped according to the convenience of the terminal device on the user side.

SUMMARY OF THE INVENTION An object of the present invention is to provide a service user with which the provision and suspension of the service can be controlled from a terminal device on the user side, thereby expanding the available services. In the case where is performing an alternate reception service of facsimile communication, it is also possible to request an alternate reception when there is no recording paper at the time of reception.

[0005]

The present invention achieves the above object.
Cannot be enjoyed in the case of facsimile communication
Storage means for registering services and facsimile communication
Before stopping the service registered in the storage means.
Control means for sending a control signal to the exchange
It is. In addition, the facsimile machine
Register a request signal requesting service supply / stop, and
When the service is stopped, the facsimile machine transmits or
Sends the request signal prior to the receiving operation, and
Services when the request signal is registered.
Stop, then perform normal facsimile communication operation,
Service will be resumed at the end of the specified communication.
It is something that has been done.

[0006]

The terminal device on the user side notifies the service providing side in advance of the receivable service, and the service providing side selectively provides the service according to the receivable service.

[0007]

FIG. 1 is a diagram showing the basic configuration of the present invention. A terminal device as a user side device includes an operation unit 1 including a display and a keyboard, a document detection unit 2 for detecting whether a document is placed on a document table, and detecting whether a telephone is on-hook or off-hook. A telephone hook detection unit 3, a main control unit 4 for controlling each component, a storage unit 5 for storing a service request / stop signal to be sent to the exchange, connection / disconnection of a line, outgoing call, incoming call And the like.

The exchange on the service providing side performs line monitoring (FIG. 7) for detecting connection / disconnection of a line, detection of a dial number, and the like, a line switching unit 8 for switching a line, and generation of services such as an interrupt service. It comprises a service providing unit 9 for transmitting accompanying signals, a main control unit 10 for controlling each component, and a service management unit 11 for managing service provision / stop based on a service contract, request / stop, and the like. .

FIG. 2 is a processing flowchart in the terminal device. When a user inputs a telephone number at the operation unit 1 of the terminal device, the main control unit 4 connects a line through the line control unit 6 and transmits a dial signal (step 1). At this time, the document detection unit 2 detects whether a document is placed, and the telephone hook detection unit 3 detects whether the telephone is in an on-hook state. In this case, the main control unit 4
If there is no original or the telephone is off-hook, it is determined that the communication is a telephone call, and if the telephone is on-hook and there is an original, it is determined that facsimile communication is performed (step 2). Next, if a service that cannot be enjoyed in the case of facsimile communication is registered in advance in the service request / stop signal storage unit 5, the main control unit 4 determines whether the service request / stop signal is registered in the storage unit 5. Is determined by the flag bit (step 3), and a service request / stop signal is sent to the exchange via the line control unit 6 (step 4).
A normal communication operation is performed (step 5).

FIG. 3 is a processing flowchart in the exchange. The line monitoring unit 7 of the exchange determines whether or not the calling terminal device is connected to the line, that is, whether or not a DC loop is formed (step 1), and subsequently detects a dial signal (step 2). . Next, when a dial signal having a specified number of digits is detected, the terminal device on the called side is specified, and a calling signal (ringer signal) is transmitted (step 3). Next, it is determined whether or not the called terminal device is connected to the line (step 4). When the calling terminal device is connected to the line, the line monitoring unit 7 detects this and stops the ringer signal (step 4). Step 5). Further, whether the terminal device has released the line, that is,
It is determined whether or not the DC loop has been released (step 6). The line in the talking state is monitored by the line monitoring unit 7, and when a service request / stop signal is detected (step 7), the main control unit 10 performs service management. The unit 11 is instructed to start / stop the service (step 8). Thereafter, when a permitted service occurs, the service providing unit 9 provides a service such as transmission of a service signal. When the terminal releases the line and the communication (or call) ends, the service started / stopped by the communication is initialized to the original state (step 9). The detection of the service request / stop signal in step 7 can be performed after the dial detection in step 2.

When tone signals are used as examples of request signals used to request service supply / stop, for example, "* 90" indicates a service supply request, "* 91" indicates a service stop request, and "* 91" indicates a service stop request. # "Is used for a delimiter signal. Therefore, for example, at the time of a service request, “* 90 # 02 # 0
The service number to be supplied is represented by "5", and the service number to be supplied is represented by "* 91 # 00 # 02" at the time of a service stop request.

[0012]

As described above, according to the present invention,
Since the service user can control the provision and suspension of the service from the terminal device on the user side, the available services can be expanded. Further, when the exchange performs an alternate reception service for facsimile communication, it is also possible to request an alternate reception when there is no recording paper at the time of reception.
