To provide a communication control method and device that can quickly implement measures to effectively reduce the effects of obstacles on wireless communication.SOLUTION: A communication control device 100 includes a data storage unit 103 that stores communication quality information that associates communication quality between a satellite and each of a plurality of ground stations with its satellite position, and a processor 102 that, when a communication degradation area where communication quality has deteriorated at a certain satellite position is detected from the communication quality information, estimates the type of obstacle that has deteriorated the communication quality from a deterioration state and time change of the communication degradation area, and selects a measure to avoid the deterioration of communication quality depending on the type of obstacle.SELECTED DRAWING: Figure 2

    【課題】無線通信への障害物の影響を効果的に低減する対策を迅速に実行できる通信制御方法および装置を提供する。【解決手段】通信制御装置100は、衛星と複数の地上局の各々との間の通信品質と衛星位置とを対応付けた通信品質情報を蓄積するデータ蓄積部103と、通信品質情報から、ある衛星位置において通信品質が劣化した通信劣化領域を検出すると、通信劣化領域の劣化状態および時間変化から通信品質を劣化させた障害物の種別を推定し、障害物の種別に応じて通信品質の劣化を回避する対策を選択するプロセッサ102と、を有する。【選択図】図2
