Summary:To realize control that appropriately compensates Quality of Service (QoS) depending on the change of the QoS in satellite communication using a multi-beam satellite.SOLUTION: A resource determination apparatus 60 determines resources for a satellite 10 that is a multi-beam satellite capable of transmitting a plurality of beams. The resource determination apparatus 60 calculates a frequency utilization efficiency for each of a plurality of target user link cells 70, 71, where each of the user link cells 70, 71 generated by a plurality of beams is defined as a calculation target cell. The resource determination apparatus 60 determines a frequency band to be allocated to each of the plurality of beams on the basis of the frequency utilization efficiency for each of the plurality of user link cells 70, 71.SELECTED DRAWING: Figure 1 【課題】マルチビーム対応衛星を用いた衛星通信において、ＱｏＳ（Ｑｕａｌｉｔｙ ｏｆ Ｓｅｒｖｉｃｅ）の変化に応じてＱｏＳを適切に補償する制御を実現可能にする。【解決手段】リソース決定装置６０は、複数のビームを送信可能なマルチビーム対応衛星である衛星１０に対するリソースを決定する。リソース決定装置６０は、複数のビームによって生成された複数のユーザリンクセル７０，７１それぞれを計算対象のユーザリンクセルとして、計算対象のユーザリンクセル７０，７１についての周波数利用効率を計算する。リソース決定装置６０は、計算された複数のユーザリンクセル７０，７１それぞれについての周波数利用効率に基づき、複数のビームそれぞれへ割り当てる周波数帯域を決定する。【選択図】図１
