Abstract:
Improving a transmission latency of a Transmission Control Protocol (TCP) is provided. The apparatus includes a communicator transmitting a message for measuring power of a transmission signal to a radio access station (RAS) and receiving a response message corresponding to the message from the RAS; a TCP manager instructed by a controller to check and store a round trip time (RTT) required for receiving an acknowledgement (ACK) corresponding to data, which is transmitted from the portable terminal to the RAS; and the controller instructing the TCP manager to measure the RTT for measuring a retransmission timeout (RTO).
