METHOD FOR CONTROLLING FAX OUTGOING CALL OF RADIO DATA COMMUNICATION INTERWORKING APPARATUS IN DIGITAL MOBILE COMMUNICATION NETWORK

摘要

PURPOSE: A method for controlling a fax outgoing call of a radio data communication interworking apparatus in a digital mobile communication network is provided to perform a fax transmission service without a fax command or a loss of data by using a transmission hierarchy protocol. CONSTITUTION: Data are received from a mobile terminal(426). The received data is compared with a page stop command(427). A TCP response method is inactivated if the received data is the page stop command(429). The received data is compared with a page end command(439). A fax state is switched to a state of D if the received data is the page end command or the fax state is switched to a state of B if the received data is not the page end command(433). The received data are transmitted to a modem if the received data is not the page stop command and the fax state is compared with a state of C(440). The data are received from the modem(434) and the received data are compared with XOFF(435). A size of TCP window is determined as O if the received data are XOFF(436). The received data are compared with XON if the received data are not XOFF(437). The size of TCP window is recovered if the received data are XON(438). The received data are transmitted to the mobile terminal if the received data are not XOFF and the received data are not XON(439). The data are received if the fax state is the state of C(426). A fax command is received from the mobile terminal if the fax state is the state of B(441).
