    摘要： A terminal apparatus is provided for receiving a broadcast service from a broadcasting system. A receiver receives a notification message from the broadcasting system. A message parser parses the notification message received by the receiver according to a certain format. A controller determines whether the received notification message is a notification message to be used by a user or a notification message to be used by the terminal based on content of the notification message parsed by the message parser, and performs an operation according to the determination result.

    摘要： A replay station and a method of operating the relay station in a multi-hop communication system are provided. A method of operating a relay station of a multi-hop communication system includes monitoring a delay of the relay station, determining whether the monitored delay exceeds a predetermined threshold, and controlling the relay station to be handed over to another upper relay station that is different from a connecting upper relay station.

    摘要： An apparatus for and method of estimating a one-way delay time between two hosts and an apparatus and method of clock synchronization using the same. The two hosts are connected to a network and communicate a predetermined packet; k-th, (k+1)-th, and (k+2)-th transmission times are measured at the first host, and k-th, and (k+1)-th transmission times are measured at the second host; a time difference of the m-th transmission time is measured at the first and second host, where m is k or k+1, and by using the measured transmission times, an m-th one-way delay time is calculated. If the time difference is identical to the calculated one-way delay time, a value equal to or less than the calculated one-way delay time is determined as the estimated one-way delay time. Accordingly, the estimation error of a one-way delay time is reduced for both symmetrically and asymmetrically connected hosts.

    摘要： A congestion control method and system in a communication system that transmits and receives a data segment using Transmission Control Protocol (TCP) and performs a Fast Retransmit mode and a Fast Recovery mode upon occurrence of a lost segment. A transmission terminal retransmits the lost segment to a reception terminal and then calculates the expected number of duplicate acknowledgements (ACKs) expected to be received from the reception terminal. The transmission terminal determines whether an ACK recently received from the reception terminal is identical to a new ACK or a duplicate ACK. The transmission terminal accumulates the received duplicate ACK, and compares the number of the accumulated duplicate ACKs with the expected number of the duplicate ACKs. The transmission terminal retransmits the lost segment to the reception terminal if the number of the accumulated duplicate ACKs is larger than the expected number of the duplicate ACKs.
