Abstract

L'invention vise à permettre de changer de mode sans interruption dans le domaine </= radio définie par logiciel >/= (SDR) de terminaux SDR par reconfiguration anticipée, dans des circonstances liées au téléchargement aval de paramètres de configuration ou de logiciel de configuration (téléchargement logiciel aval). Si pour certaines régions aucun mode utilisable n'est disponible, on peut d'abord déterminer à partir de quel lieu la réception renouvelée de la liaison radio est possible puis prendre les mesures correspondantes. En outre, dans les deux cas, le nouveau mode peut être choisi de telle façon qu'il soit optimal tant en termes d'itinéraire consécutif que d'éventuelles reconfigurations ultérieurement nécessaires.
