WIRELESS INTERNET SYNCHRONIZATION METHOD IN A MOBILE TERMINAL, ESPECIALLY CONCERNED WITH ACHIEVING A MOBILE TERMINAL'S SMOOTH DATA TRANSMISSION AND RECEPTION BY SYNCHRONIZING A TCP/IP WITH A WAP BROWSER WHEN DATA IS TRANSMITTED AND RECEIVED AND WHEN A CLIENT'S CONNECTION REQUEST IS MADE

摘要

PURPOSE: A wireless Internet synchronization method in a mobile terminal is provided to enable a WAP(Wireless Application Protocol) browser to set up a TCP/IP connection using a socket internally and to execute data transmission and reception so that a user can use a VOD(Video On Demand) service, an MMS(Multimedia Message Service), an FTP(File Transfer Protocol) service, etc., using the WAP browser. CONSTITUTION: If a WAP application calls a send function in order to transmit a specific message, a socket API(Application Protocol Interface) calls a socket_send() function to a TCP/IP. At this moment, if there is no space in a buffer to store a string to be transmitted, the TCP/IP returns 'wouldblock' to the WAP application. Accordingly, the WAP application executes another work without waiting until the buffer gets empty. Afterwards, if a vacant space in the buffer is made, the TCP/IP transmits a notification event to the WAP application. The WAP application calls the send function again in order to attempt data transmission.
