METHOD FOR CONNECTING DATA COMMUNICATION IN RADIO ENVIRONMENT

摘要

PURPOSE: A method for connecting data communication in radio environment is provided to perform Internet access without the use of TCP/IP/PPP stack in a terminal device by using TCP/IP/PPP stack in a radio communication terminal. CONSTITUTION: A terminal device receives an Internet access ready instruction (AT+CRM=135) from a terminal(301). The terminal device drives TELNET, TCP, IP, and PPP for accessing Internet(302). The terminal receives a request of Internet access(ATDT001)(303). The terminal device receives the notification of connection(CONNECT), and makes a request of LCP(304). The terminal device makes LCP negotiation with IWF(305). The IWF understands a direct access structure of the terminal device, IP assignment and PPP access is completed(306). A desired IP address is sent to the IWF by using TCP protocol, and data communication is carried out(307).
