Abstract

L'invention concerne un procédé de programmation comprenant les étapes consistant à : acquérir un flux d'application pour une communication par satellite dans chacun d'un ou plusieurs groupes de stations d'extrémité ; configurer, d'après le flux d'application acquis pour une communication par satellite dans chaque groupe de stations d'extrémité, des ressources d'interface radio pour chaque groupe de stations d'extrémité ; lorsque les ressources d'interface radio devant être configurées pour le premier groupe de stations d'extrémité dans le ou les groupes de stations d'extrémité dépassent une limite, programmer, selon le droit autorisant le premier groupe de stations d'extrémité à faire un usage excessif de ressources d'interface radio, les ressources d'interface radio appartenant aux autres groupes de stations d'extrémité du ou des groupes de stations d'extrémité, pour le groupe de stations d'extrémité dont les ressources d'interface radio dépassent la limite.
