Abstract

L'invention concerne un procédé de traitement d'un paquet de données. Le procédé comprend les étapes suivantes : une première entité de couche de protocole divise une première SDU en au moins deux segments de SDU en fonction de la taille de la première SDU reçue ; et la première entité de couche de protocole indique que le segment de SDU est un segment de données de la première SDU. L'invention concerne aussi un autre procédé de traitement de paquet de données, une entité et un support de stockage.
