Abstract

Selon des modes de réalisation, la présente invention concerne un procédé de communication sans fil, un dispositif de réseau et un dispositif terminal. Le procédé comprend les étapes suivantes : un dispositif de réseau déclenche un dispositif terminal pour configurer un second protocole de convergence de données par paquets (PDCP) ; avant que le dispositif de réseau ne reçoive un premier message, qui est généré sur la base du second PDCP et envoyé par le dispositif terminal, le dispositif de réseau analyse, sur la base d'un premier PDCP, le message envoyé par le dispositif terminal. Le procédé, le dispositif de réseau et le dispositif terminal selon les modes de réalisation de la présente invention facilitent l'analyse correcte par le dispositif de réseau du message envoyé par le dispositif terminal.
