Abstract

La présente invention porte sur un procédé de traitement de données, un appareil et un module de couche de protocole de convergence de données par paquets (PDCP). Le procédé comprend les opérations suivantes : une couche PDCP règle un temporisateur d'envoi pour un message de liaison montante ou message d'acheminement de liaison montante reçu; s'il est détecté qu'un temps de résidence pour le message de liaison montante ou message d'acheminement de liaison montante dans une fenêtre glissante de réception de liaison montante est plus long que la durée de temporisation du temporisateur d'envoi, alors le message est envoyé à une couche supérieure. La présente invention peut assurer que des messages de liaison montante PDCP ou des messages d'acheminement de liaison montante PDCP sont envoyés avec succès à la couche supérieure.
