PROBLEM TO BE SOLVED: To provide a control method of a real-time Internet facsimile communication system which can reduce increase of communication charge. SOLUTION: A communication system is constituted of a plurality of real-time Internet gateway units and a plurality of group 3 facsimile apparatus. In a transmitter gateway unit, when a transmitting request is received from a transmitter facsimile apparatus, while a telephone number of an informed recipient facsimile apparatus is informed, connection request is performed to a recipient gateway unit. If busy state or connection failure of the recipient facsimile apparatus is detected based on received information, real-time Internet facsimile communication operation is interrupted. After that, group 3 facsimile communication is continued with the transmitter facsimile apparatus, and image information is received from the transmitter facsimile apparatus and accumulated. When reception in the recipient facsimile apparatus is enabled, the accumulated image information is transmitted to the recipient facsimile apparatus. COPYRIGHT: (C)2006,JPO&NCIPI
