Abstract

L'invention concerne un procédé, un appareil et un système de radiomessagerie, et une UC, une AMF et un support d'enregistrement, qui sont utilisés pour résoudre le problème de l'état de la technique d'incapacité à effectuer une radiomessagerie répétée dans un mode de séparation UC/UD. Le procédé comprend les étapes suivantes dans lesquelles : une unité centrale (UC) reçoit un premier message de radiomessagerie envoyé par une AMF d'un réseau central, le premier message de radiomessagerie transportant des informations d'un premier cycle de réception discontinue (DRX) d'un terminal (UE) à appeler ; envoie, en fonction du premier message de radiomessagerie, les informations du premier cycle DRX de l'UE à chaque unité de distribution (UD), de sorte que chaque UD appelle l'UE ; et si l'UC détermine qu'il existe une UD cible qui effectue une seconde radiomessagerie, l'unité centrale envoie un second message de radiomessagerie pour l'UD cible à l'UD cible, l'UD cible n'ayant pas reçu de réponse de radiomessagerie pour l'UD cible après un cycle DRX cible correspondant à l'UD cible.
