Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intra-same-call receiving system when, for example, a call is made from a facsimile and an image is received using a line.

[0002]

2. Description of the Related Art Conventionally, when image data is received from a mail box or the like in a communication device via a line using a facsimile or the like, first the facsimile becomes the calling side, and the request dial is made after off-hook. At this point, the transmission right is on the facsimile side in order to make a call.

However, in reality, the facsimile must be the image receiving side. For that purpose, the call is temporarily disconnected after the request dial, and the call is again sent from the communication device to the facsimile. However, this causes calls to occur twice, resulting in line charges for the communication device and the facsimile.

CCITT Recommendation T. According to 30,
It is possible to transfer the transmission right to the called side by the DTC (digital transmission command signal) from the calling side.
In this case, the calling side facsimile often does not have a function of delegating the transmission right as a terminal function, and cannot be applied to a connection between a communication device and a general public facsimile.

[0005]

According to the conventional method, since the image data of the called side cannot be received in the same call from the facsimile which is the calling terminal for the above reasons, the calling side cannot be called. I have to run it twice. Or D
There are problems such as having to rely on a special facsimile capable of transmitting TC signals.

The present invention has been made in order to solve the above-mentioned problems, and the calling side facsimile, which is the charging target of the line fee, can receive an image within the same call.
The object is to allow the called communication device to transmit an image without being charged, and further to provide a communication method suitable for this communication device.

[0007]

The in-same-call receiving system according to the first invention comprises the following calling side and called side devices. (A) Calling side device having the following elements: (a1) Calling means for making a call to the called side device and issuing a request to receive data in the called side device, (a2) Own device is the receiving side device Receiving conversion means for transmitting a reception side signal to be sent to the transmission side device to the call side device, (b) a call side device having the following elements (b1) responding to a call from the call side device, Response means for responding to a data reception request from the calling side device, and (b2) a receiving side when the own device is the transmitting side device based on the receiving side signal transmitted by the reception conversion means of the calling side device. Transmission conversion means for transmitting a transmitting side signal to the device to the calling side device.

The same call receiving system according to the second invention has the following steps. (A) A connecting step in which the calling side makes a call to the called side to connect the call, (b) After the connecting step, the calling side requests the called side to send predetermined data, (c) After the request step, the calling side transmits a called terminal identification signal CED and a digital identification signal DIS to the called side, and the called side responds to the digital command signal DC
A conversion step of returning S, and (d) a data reception step of receiving the data requested by the calling side in the requesting step from the called side in the same call after the conversion step.

[0009]

In the same call receiving system according to the present invention, the call from the calling facsimile (calling side device) is connected by the connecting step and the requesting step, and the communication device (callee side device) performs the request dial. While performing analysis, it returns a response signal and waits for the next operation on the facsimile side (calling means and response means). Next, in the conversion process, the facsimile (calling side device) does not set the transmission image and presses the FAX button, so that CED (callee terminal identification signal) and DIS (digital identification) indicating the standard capability of the receiver side are displayed. Since the signal) is returned (reception conversion means), the communication device (incoming side device) returns a DCS (digital command signal) correspondingly, and the transmission right is inverted at this point (transmission conversion means). ). In this way, the communication device (callee device) can transmit the image, and the calling facsimile (caller device)
Since the image can be received within the same call, the data based on the request dial can be transmitted within the same call from the communication device (the called device) to the facsimile (the calling device) in the data receiving step.
