Abstract: A variation compensating unit that compensates an amplitude variation and phase variation efficiently and that improves system reliability and communication quality. A first combining section generates a first combined signal by combining signal on different transmission paths in which a variation has not occurred. A second combining section generates a second combined signal by combining signal on the different transmission paths in which a variation has occurred. A compensation value calculating section calculates compensation values for compensating variation according to the transmission paths on the basis of the first combined signal, the second combined signal, and signal on each transmission path in which a variation has not occurred or in which a variation has occurred. A compensating section compensates variation dynamically on the basis of the compensation values.

Abstract: Data can be transmitted efficiently by sending control information as demanded by the status of a network. To accomplish this, a transmitting terminal transmits data using the Real-Time Transport Protocol (RTP), and control information, which is for ascertaining the status of the network, is transmitted by both the transmitting terminal and a receiving terminal using the Real-Time Transport Control Protocol (RTCP). The transmitting terminal transmits the control information as an RTCP packet at predetermined time intervals. If the transmission rate does not attain a target rate, however, the transmitting terminal raises the transmission rate by a predetermined percentage regardless of the predetermined time intervals. If it is judged that transmission loss has occurred based upon the control information sent from the receiving terminal, the transmitting terminal lowers the transmission rate by a predetermined percentage regardless of the predetermined time intervals.

Abstract: A wireless telecommunication system receives information from a wireless mobile unit and determines that the wireless mobile unit is within a designated region. Information specific to the designated region is received at a centrally located location-based message server. As the traveler enters the designated region, the wireless mobile unit then receives information specific to the designated region such as information relating to traffic problems or desired locations within the region. Alternatively, a problem is identified and designated as relating to a particular region, and wireless mobile units within the designated region are then identified so that information relating to the problem can be output thereto. As such, information specific to a region occupied to a traveler is received.
