Abstract

PURPOSE:To change a station which is charged by transmitting an outgoing and incoming call conversion request, the telephone number of an origination side, and a password predetermined between the origination side and a termination side from the origination side, and calling the origination side automatically from the termination side after the termination side confirms the password and disconnects the circuit. CONSTITUTION:The origination side sends out an identification signal for setting a nonstandard device, reports the request for outgoing/incoming call conversion and the password for said conversion, and also sends its dial number in specific pattern. The reception side, on the other hand, decides the password for outgoing/incoming call conversion, and then returns a signal for reception preparation confirmation and stores the dial number of the originating station when the password coincides with a previously specified password. In this case, the origination side sends out a circuit disconnection command and disconnects the circuit. The termination side performs the outgoing/incoming call conversion after the circuit is disconnected and dials the dial number stored during nonstandard device setting reception automatically, and follow a normal facsimile procedure thereafter.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention is applied to a facsimile communication system connected via a public telecommunications network.

〔overview〕

In a system where information is sent and received via a telephone network using a facsimile machine that automatically makes and receives calls, if the calling party notifies the other party of his or her telephone number and requests call conversion, the called party cannot make the call. By confirming a predetermined password sent by the calling party and then converting the call, the burden of call charges can be shifted.

[Conventional technology]

Conventionally, in a facsimile communication system that uses automatic call control over a telephone network, manual intervention is required to convert calls.

[Problems to be solved by Invention C] However, in this type of system, the calling party is always charged for the use of the telephone network, regardless of the flow of image information sent and received, so the customer does not have to pay for the use of the telephone network. There may be cases where you do not want to be burdened with this.

An object of the present invention is to solve this drawback and provide a facsimile communication connection system that can shift the burden of call charges.

[Means for solving problems]

The present invention provides a connection system for a facsimile machine with an automatic call origination/reception function via a telephone network, in which a calling side device notifies a called side device of a calling station dial number, means for notifying a calling/receiving call exchange request, and The called device has a means for notifying the password for outgoing/incoming call conversion, and the called device has a means for comparing the password for outgoing/incoming call conversion with a prespecified password according to the outgoing/incoming call conversion request notified from the calling device. The present invention is characterized in that it has means for making a call to the calling station dial number after the line is disconnected.

That is, the present invention provides a system in which a first facsimile communication device and a second facsimile communication device are connected via a public telecommunications line, and in which a call is made from the first facsimile communication device and a second facsimile communication is made. After the devices are connected, the first facsimile communication device sends an outgoing/incoming call conversion request signal, its own telephone number, and a password to the second facsimile communication device, and the second facsimile communication device has this password set in advance. The first facsimile communication device is characterized in that, after confirming that the facsimile communication device matches the received information, the line is once disconnected, and then a call is made to the first facsimile communication device to transmit the information.

[For production]

When performing facsimile communication via a public telecommunications line, if you want the called party to be responsible for the call charges, the calling party, after connecting to the called party's device, sends a call conversion request, its own telephone number, and both parties in advance. If you send the password specified in , the called party will confirm this password, disconnect the line, and then automatically call the calling party and change the station where charges will be applied. I can do it.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of the above embodiment.

In FIG. 1, two similar sets of facsimile machines with automatic call/receive functions are connected via a telephone network 5. In FIG.

Each facsimile machine has communication network control units IA and IB, respectively.
, modem devices 2A, 2B, transmission control units 3A, 3B, and terminal control units 4A, 4B.

The calling procedure will be explained. The dial number of the other station is notified from the terminal control section 4A to the transmission control section 3A, and automatic dialing to the other station is performed through the communication network control section IA.

The incoming call procedure will be explained. The communication network control unit IB detects the ringing signal and notifies the transmission control unit 3B of the incoming call,
The transmission control unit 3B notifies the terminal control unit 4B.

Transmission of procedure signals will be explained. The transmission control unit 3A notifies the modulation/demodulation device 2A of a procedure signal, and the modulation/demodulation device 2
A is sent to the telephone y45 through the communication network control unit IA.

Receiving a procedure signal will be explained. The procedure signal received from the telephone network 5 through the communication network control unit IB is sent to the modulation/demodulation device 2.
The transmission control unit 3B is notified through B.

FIG. 2 is a diagram for explaining the procedure of call conversion. Here, the procedure signal is in accordance with International Telegraph and Telephone Advisory Committee Recommendation T30.

FIG. 2 (al) shows the normal procedure for call conversion.

When the calling party dials the called party, the called party receives the ringing signal and automatically responds. Following the called station identification, the non-standard equipment identification signal and digital identification signal, which are initial identification signals, are returned to the sending party. . Here, the non-standard device is an optional signal to identify a specific user request,
Identification of whether or not the called side is a device capable of converting originating and receiving calls is indicated by a specific bit of a non-standard device frame.

Therefore, on the calling side, if the non-standard device is identified and the called side is a device that can convert the originating/incoming call, it sends an identification signal of the non-standard equipment setting, requests the originating/incoming call conversion, and sends an identification signal for the originating/incoming call conversion. Notify the password. Non-standard equipment settings are optional signals that identify a specific user's request, indicating a call conversion request with a specific bit, a password for calling/incoming call conversion with a specific pattern, and the dialed number of the local station. be shown in a specific pattern. In response to the non-standard device settings, the receiving side determines the password for converting incoming and outgoing calls, and if it matches the password specified in advance, returns a reception preparation confirmation signal and stores the dial number of the calling station. If the passwords match and a reception preparation confirmation is sent, the calling side sends a line disconnection command and disconnects the line.

On the called side, after the line is disconnected, call conversion is performed and automatic dialing is performed to the dial number stored at the time of receiving the non-standard device settings, and from then on, normal facsimile procedures are followed.

The feature of the present invention is that, after the called device identifies the non-standard device settings, the calling device requests the called party to perform call conversion and If the password matches the pre-registered password, the called device confirms reception readiness, stores the calling party's telephone number included in the non-standard device settings, and After the line is disconnected, this phone number will be automatically dialed, and from now on, the called party will be converted to the calling party.

When determining the password on the called side, if there is a mismatch, a line disconnection command is sent and the line is disconnected. This procedure is shown in FIG. 2(b).

In addition, if a call is made for the purpose of converting a call at the calling station, but the called device does not have the ability to convert the call, a line disconnection command is sent to the non-standard device and digital identification signal, and the line is disconnected. shall be. This procedure is shown in FIG. 2(C).

〔Effect of the invention〕

As explained above, according to the present invention, the burden of call charges can be transferred to the other party upon mutual agreement. This has the advantage that customers are not forced to engage in forms of commercial transactions, such as having to pay for telephone calls.
