A method and system for communicating a packet over a cell relay satellite network (110), without establishing a connection in the cell relay satellite network (110), include segmenting the packet into a number of segments at a source node (100a-100f) in the network, generating for each of the segments a fixed size cell that includes a cell header (310) and payload (320) with a prefix (330), a downlink beam locator (340), and a source node identifier (350) included in the cell header (310), and inserting each segment into the payload (320) for each generated cell, respectively, and transmitting the cells to the cell relay satellite (150a-150f). A cell relay satellite (150a- 150d) receives each transmitted cell from the source node (100a-100f), and broadcasts each cell on a downlink beam corresponding to be downlink beam locator (340) in each cell header (310).

L'invention porte sur un procédé et un système de transmission d'un paquet sur un réseau cellulaire à satellite relais (110) sans avoir à y (110) établir de connexion consistant: à découper le paquet en plusieurs segments au niveau d'un noeud source (100a-100f) du réseau; à créer pour chaque segment une cellule de taille fixe compremant un en-tête (310) et une charge utile (320) avec un préfixe (330), un repère (340) de faisceau descendant, et un identificateur (350) de noeud source placé dans l'en-tête de la cellule; à insérer chacun des segments dans la charge utile (320) de chacune des cellules créées; puis à transmettre les cellules au satellite (150a-150f) relais cellulaire qui reçoit les cellules émises par le noeud source (100a-100f) et les diffuse sur un faisceau descendant correspondant au repère (340) de faisceau descendant de chacun des en-tête (310) de cellules.
