Abstract:
(EN) In a satellite communication system (100), a broadcast communication group consisting of a plurality of areas is allocated to each of a plurality of frequency bands. A gateway (300) transmits an uplink signal that has the plurality of frequency bands and that includes transmission data in one of the plurality of frequency bands that is allocated to areas in which the destination of the transmission data exists. A communication satellite (200) receives the uplink signal and, for each of the frequency bands the uplink signal has, transmits a downlink signal corresponding to the frequency band of the uplink signal to the broadcast communication group of the frequency band.
(FR) Selon l'invention, dans un système de communication par satellite (100), un groupe de communication de diffusion constitué d'une pluralité de zones est attribué à chaque bande d'une pluralité de bandes de fréquences. Une passerelle (300) transmet un signal de liaison montante qui comporte la pluralité de bandes de fréquences et qui contient des données de transmission dans une bande de la pluralité de bandes de fréquences qui sont attribuées à des zones dans lesquelles se trouve la destination des données de transmission. Un satellite de communication (200) reçoit le signal de liaison montante et, pour chacune des bandes de fréquences présentes dans le signal de liaison montante, transmet un signal de liaison descendante correspondant à la bande de fréquences du signal de liaison montante au groupe de communication de diffusion de la bande de fréquences.
(JA) 衛星通信システム(100)において、複数の周波数帯域の周波数帯域毎に複数の地域から成る同報通信グループが割り当てられる。ゲートウェイ(300)は、前記複数の周波数帯域を有して前記複数の周波数帯域のうち送信データの宛先が存在する地域に割り当てられた周波数帯域に前記送信データを含むアップリンク信号を送信する。通信衛星(200)は、前記アップリンク信号を受信し、前記アップリンク信号が有する周波数帯域毎に前記アップリンク信号の前記周波数帯域に対応するダウンリンク信号を前記周波数帯域の同報通信グループに送信する。
