Abstract

Selon certains modes de réalisation, la présente invention concerne un procédé, un dispositif et un support lisible par ordinateur pour la transmission de données sans connexions RRC. Selon des modes de réalisation de la présente invention, les segments de paquet de données peuvent être transmis sans l'établissement de la connexion RRC par l'introduction d'une planification semi-persistante dans la transmission précoce, ce qui permet d'économiser la consommation de signalisation.
