Abstract

L'invention porte sur un procédé et sur un appareil de liaison de flux de données, ainsi que sur un support de stockage informatique. Le procédé comprend les étapes suivantes : un premier élément de réseau d'accès reçoit un message de demande d'établissement ou un message de demande de modification pour un flux de données dans une session d'unités de données de protocole (PDU) envoyé par un premier élément de cœur de réseau ; et le premier élément de réseau d'accès lie, conformément au message de demande d'établissement ou au message de demande de modification, chaque flux de données et/ou session à établir ou à modifier à un support radio sous une technologie d'accès radio (RAT) correspondante.
