METHOD CAPABLE OF IMPROVING DATA TRANSMISSION RATIO USING ACK PIGGY-BACKING OF TCP IN THE ASYMMETRIC WIRELESS NETWORK ENVIRONMENT AND A TERMINAL AND SYSTEM THEREOF

摘要

A method and a terminal for improving a data transmission ratio of TCP, and a system therefor are provided to remove a congestion of each uplink and to reduce a loss or a delay of an ACK packet by piggy-backing the ACK packet to an IP packet according to a traffic situation. A method for improving a data transmission ratio of TCP includes the steps of: determining an ACK packet to be transmitted to a server for checking receiving of the data downloaded by a mobile terminal(305); determining an uplink traffic situation after pending the ACK packet if the ACK packet exists(310); and if an IP packet to be uploaded exists based on a determination result, transmitting the ACK packet, which is pended to a predetermined field of the IP packet, to the server through a middle node(345).
