SOLUTION: A transmitter side system 2 transmits information desired to be transmitted with a telephone number in a numeric code from attached thereto, an exchange 1 receiving the telephone number and the information stores them entirely so as to be communicated via a channel, contents desired to be transmitted are arrived in the exchange 1 connected to a receiver side system 3 before the channel connection is established, and the exchange 1 transmits the information to the receiver side system 3 as soon as the channel connection is established. Thus, a sender can complete the transmission of the information before the channel connection is established so as to remarkably reduce a channel utilizing time being a charging object and to reduce the communication cost.
