Abstract

La présente invention concerne un procédé de radiomessagerie, un dispositif terminal et un dispositif réseau. Le procédé comprend les étapes suivantes : un dispositif terminal détermine une première sous-identité et une seconde sous-identité sur la base d'une identité de dispositif dudit terminal ; le dispositif terminal détermine des informations temporelles pour recevoir un message de radiomessagerie de ce dernier en fonction de la première sous-identité, le message de radiomessagerie transportant la seconde sous-identité, et les informations temporelles comprenant soit une trame radio de radiomessagerie (PF) pour recevoir le message de radiomessagerie, soit la PF et une occasion de radiomessagerie (PO) dans la PF pour recevoir le message de radiomessagerie ; le dispositif terminal reçoit le message de radiomessagerie selon les informations temporelles. Par conséquent, le dispositif réseau peut envoyer efficacement un message radio au dispositif terminal sur la base de la seconde sous-identité sans provoquer un important surdébit de ressource, et même si des secondes sous-identités compressées de différents dispositifs terminaux sont identiques, le dispositif terminal peut également identifier efficacement son propre message de radiomessagerie selon un temps de transmission différent, de façon à déterminer s'il est envoyé par le dispositif réseau ou pas, et à réduire les erreurs de radiomessagerie.
