Abstract

L'invention concerne un procédé d'établissement d'une ou de plusieurs liaisons pour un accès et une liaison terrestre intégrés pour un réseau, le réseau comprenant un nœud non terrestre (114) et un nœud terrestre (110, 112, 245), le procédé comprend la détermination (602) d'une pluralité de liaisons (520, 522, 524) à former entre un nœud non terrestre (114) et un certain nombre de nœuds (110, 112, 245) dans le réseau et la formation (604) de la pluralité de liaisons (520, 522, 524) à former. Le procédé comprend également la détermination (606) d'une pluralité de chemins de routage pour la liaison terrestre entre le nœud non terrestre (114) vers un serveur central, la fourniture (608) des instructions de liaison terrestre entre le nœud non terrestre (114) et le serveur central à l'aide de la pluralité de chemins de routage, et la transmission (614) d'un premier ensemble de données à la liaison terrestre par l'intermédiaire d'un premier trajet de routage de la pluralité de trajets de routage et d'un second ensemble de données à la liaison terrestre par l'intermédiaire d'un second trajet de routage de la pluralité de trajets de routage.
