Abstract(in English) The third generation wireless communication system known as IMT-2000 with wide bandwidth of a maximum of 384kbps, in turn, provides high-speed data transmission and access to the Internet. As a channel utilization characteristic of IMT-2000, propagation delay for a message and the corresponding reply is considered to be much larger compared to the bandwidth. The higher the delay, the greater the stress placed on the transport protocol to operate efficiently. There is a huge impact on TCP performance seen for conventional TCP with greater amounts of data held "in transit" in the network, hence, inefficiency. TCP profile of W-CDMA has been proposed to enable such TCP to more effectively utilize the available capacity of the network path. In this paper, we propose a transparent proxy method to convert TCP profile of W-CDMA to and from legacy TCP, and implement this method to gateway system. We performed simulation under the third generation mobile network and evaluated its efficiency.
