Abstract

PROBLEM TO BE SOLVED: To make maximum use of the receiving capacity of the facsimile equipment of an opposite party in the facsimile equipment based on ITU recommendation T.37 capable of transmitting data regardless of the state of the facsimile equipment of the opposite party. SOLUTION: The receiving capacity of a receiving side facsimile equipment is stored (S8), and when the facsimile equipment of the opposite party is designated from a user (S1, S2), whether the receiving capacity of the facsimile equipment of the opposite party is stored or not is discriminated (S3). When the receiving capacity of the facsimile equipment of the opposite party is stored as the result of the discrimination, transmission by an electronic mail communication system based on the ITU recommendation T.37 is requested to a gateway (S4) and transmission corresponding to the stored receiving capacity of the facsimile equipment of the opposite party is performed. When it is discriminated that the equipment is not stored, transmission by a real time facsimile communication system based on the ITU recommendation T.37 is requested to the gateway (S6).

2. Description of the Related Art In recent years, the spread of data communication using the Internet has been remarkable.

An ITU for real-time communication of video data and voice data using the Internet
Recommendation H. H.323 and ITU Recommendation T.323 for performing facsimile communication in real time. 38 have been proposed. In addition, ITU Recommendation T.40, which converts facsimile data into a TIFF file and transmits it by E-MAIL. 37 have also been proposed. A device using these can realize communication at low cost via the Internet. ITU Recommendation T. In 38, since the transmitting terminal directly exchanges data with the terminal that finally receives the data, it is convenient that the delivery confirmation of the data can be performed in real time.

FIG. 6 shows an ITU recommendation T.1 which performs facsimile communication in real time using the Internet. FIG. 1 is a diagram showing an example of a configuration of a conventional communication system based on No.38.

In the figure, 101 is the Internet, 102 is a transmission facsimile machine, 103 is a reception facsimile machine,
Reference numeral 104 denotes a transmission gateway (GW), and reference numeral 105 denotes a reception gateway (GW). Transmission GW104, reception GW1
05 is connected to the Internet 101 and performs data communication via the Internet 101. The transmission facsimile apparatus 102 and the reception facsimile apparatus 103 are generally used G3 facsimile apparatuses, and are normally connected to analog public networks (PSTN) 106 and 107, respectively, to transmit or receive G3 facsimile such as image information. Is what you do. Here, the transmission facsimile device 1
02 is the transmission GW 104 and the reception facsimile device 103
Is connected to the receiving GW 105 via the PSTNs 106 and 107, respectively.
GW 104, Internet 101, GW
Real-time Internet facsimile communication of image information and the like can be performed to the reception facsimile apparatus 103 via the communication terminal 105.

FIG. 7 shows a transmission facsimile apparatus 102 for transmitting image information and the like in the conventional communication system shown in FIG.
FIG. 6 is a diagram showing a communication sequence when transmitting from the FAX to the reception facsimile apparatus 103.

First, the transmission facsimile apparatus 102 connected to the PSTN 106 performs off-hook and dial operations to call the transmission GW 104. The transmission GW 104 detects the call, responds to the call, and goes off-hook. When the transmission GW 104 goes off-hook, the transmission GW 104 and the transmission facsimile
2 is connected via the PSTN 106 (110).

[0008] The transmission GW 104 uses the information of the facsimile transmission destination transmitted from the transmission facsimile apparatus 102 to
The receiving GW 105 connected to the end of the Internet 101 is specified, and a data packet including a call setting signal is transmitted to the specified receiving GW 105 via the Internet 101 (111). Here, it is assumed that the call setting signal includes information for specifying the receiving facsimile apparatus 103 as the facsimile transmission destination. When receiving the call setting signal packet, the reception GW 105 specifies the reception facsimile apparatus 103 and connects to the reception facsimile apparatus 103 (11).
2). The receiving GW 105 detects this connection, and sends the GW 1
Then, a data packet composed of a call connection signal is transmitted to Internet 04 via the Internet 101 (113). According to these sequences, the transmission GW 104 and the reception GW 105 connect a FAX channel via the Internet 101 (114), and the transmission facsimile apparatus 102 and the transmission GW 1
04, the reception GW 105, and the reception facsimile apparatus 103, T.38 specified in Operation of 38 sessions becomes possible (115), and image information and the like can be transmitted from the transmission facsimile apparatus 102 to the reception facsimile apparatus 103.

When the transmission facsimile apparatus 102 completes the facsimile transmission operation, it performs an on-hook operation.
02 is disconnected (116), and a data packet including a release completion signal is transmitted to the receiving GW 105 via the Internet 101 (117). Receive GW1
05 receives the release completion signal packet, sends the busy tone of the receiving facsimile apparatus 103 (118), and the receiving facsimile apparatus 103 performs an on-hook operation in response to this (119).

Thus, the sequence of the real-time Internet facsimile communication is completed.

[0011]
