Communication device, communication system, and communication method

通信装置、通信システムおよび通信方法

Abstract

【課題】データの種類および目的等に応じて適切にデータ伝送を行なうことが可能な通信装置、通信システムおよび通信方法を提供する。 【解決手段】通信装置は、複数個の論理チャネルを含んだ周波数の異なる複数個の通信信号を通信相手から受信する受信部62と、受信した通信信号の回線状態を測定する測定部53と、論理チャネルの各々に通信信号を割り当てる通信信号割り当て部51と、論理チャネルごとにマージン値を設定し、対応する論理チャネルに設定したマージン値を通信信号のマージン値とするマージン設定部55と、測定した回線状態から通信信号のマージン値だけ劣化した回線状態において複数個の通信信号の誤り率がそれぞれ所定値未満となるように複数個の通信信号の通信速度をそれぞれ決定する通信速度決定部51と、通信信号の割り当て結果および決定した通信速度を通信相手に通知する送信部61とを備える。 【選択図】図2
PROBLEM TO BE SOLVED: To provide a communication device, communication system and communication method, which can suitably transmit data according to data type, purposes and so on. SOLUTION: The communication device includes a receiver 62 for receiving a plurality of communication signals including a plurality of logic channels and having different frequencies from a communication party, a measurer 53 for measuring line states of the received communication signals, a communication signal allocator 51 for allocating the communication signals to the respective logical channels, a margin setter 55 for setting margin values for the respective logic channels to use the margin values set for the corresponding logic channels as the margin values of the communication signals, a communication rate determiner 51 for determining communication rates for the plurality of communication signals respectively in such a manner that error rates for the plurality of communication signals are lower than a predetermined value in line states which are deteriorated by the margin values of the communication signals from the measured line states, and a transmitter 61 for informing the communication party of allocated results of the communication signals and the communication rates.
