The invention proposes a method for transferring information from a mobile network sender through a voice channel. The method includes sending request by means of a sender terminal for connection with a receiver terminal, receiving by the receiver terminal of a message for above mentioned request, check by the receiver of a sender terminal number, set connection between the sender terminal and the receiver terminal, transferring message by means of the sender terminal as DTMF signals, receiving the message on the receiver terminal, which controls session duration of receiving the message, and also message integrity and authentication of received message. In case of receiving integrity and authentication message, a receiver produces a DTMF-signal that confirm receiving the message and the sender terminal controls the received DTMF signal and connection state. If DTMF signal corresponds to positive confirmation of received message and connection is not broken, the sender transfers the next message, if it is available, or breaks the connection. If DTMF signal received by the receiver terminal from the sender terminal corresponds to negative confirmation of received message and connection is not broken, the sender retransfers the message or until receives the positive confirmation, or exhausts repeating attempts, or the receiver terminal side breaks connection. If the session is finished, the receiver terminal breaks connection. |
