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).
Claims21
A portable terminal for reducing a latency of a Transmission Control Protocol (TCP), comprising:
- 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).
A method of reducing a latency of a TCP in a portable terminal, comprising:
- checking an RTT required for receiving an ACK corresponding to data which is transmitted from the portable terminal to an RAS;
- and
- storing the RTT.
A method of setting a TCP retransmission timer in a portable terminal, comprising:
- obtaining a pre-stored RTT if an event for setting the TCP retransmission timer occurs;
- measuring power of a transmission signal of the portable terminal;
- measuring an RTO using the RTT and the power of the transmission signal;
- and
- setting the TCP retransmission timer using the measured RTO.
A method of setting a TCP retransmission timer in a portable terminal, which performs a handover process, comprising:
- obtaining a pre-stored RTT if an event for setting a TCP retransmission timer occurs;
- measuring power of a transmission signal of the portable terminal and a handover latency time;
- measuring an RTO using the RTT, the power of the transmission signal, and the handover latency time;
- and
- setting the TCP retransmission timer using the RTO.
A method of reducing a latency of a TCP in a portable terminal, comprising:
- means for checking an RTT required for receiving an ACK corresponding to data which is transmitted from the portable terminal to an RAS;
- and
- means for storing the RTT.
A method of setting a TCP retransmission timer in a portable terminal, comprising:
- means for obtaining a pre-stored RTT if an event for setting the TCP retransmission timer occurs;
- means for measuring power of a transmission signal of the portable terminal;
- means for measuring an RTO using the RTT and the power of the transmission signal;
- and means for setting the TCP retransmission timer using the measured RTO.
A computer-readable recording medium having recorded thereon a program reducing a latency of a TCP in a portable terminal, comprising:
- a first segment, for checking an RTT required for receiving an ACK corresponding to data which is transmitted from the portable terminal to an RAS;
- and
- a second segment, for storing the RTT.
A computer-readable recording medium having recorded thereon a program setting a TCP retransmission timer in a portable terminal, comprising:
- a first segment, for obtaining a pre-stored RTT if an event for setting the TCP retransmission timer occurs;
- a second segment, for measuring power of a transmission signal of the portable terminal;
- a third segment, for measuring an RTO using the RTT and the power of the transmission signal;
- and
- a fourth segment, for setting the TCP retransmission timer using the measured RTO.
