Abstract

La présente divulgation, qui relève du domaine des communications sans fil, concerne un procédé et un appareil de communication, une station de base, un relais mobile et un support de stockage. La solution de mise en œuvre spécifique implique : l'acquisition, par une station de base, d'une première position d'un relais mobile et d'une seconde position d'un terminal, le terminal recevant des données de la station de base au moyen du relais mobile; la détermination d'informations de trajet planifié du relais mobile selon l'efficacité énergétique du relais mobile, la première position du relais mobile et la seconde position du terminal; et l'envoi des informations de trajet planifié au relais mobile. De cette manière, il est possible de déterminer des informations de trajet planifié d'un relais mobile au moyen d'une station de base et selon l'efficacité énergétique du relais mobile, la position du relais mobile et la position d'un terminal. Puisque les informations de trajet planifié sont déterminées en combinaison avec l'efficacité énergétique du relais mobile, l'état d'efficacité énergétique du relais mobile peut être intégralement pris en considération de sorte que l'efficacité énergétique du relais mobile peut être améliorée lorsque le relais mobile se déplace selon les informations de trajet planifié, ce qui étend la durée de service de communication du relais mobile.
