Abstract

Procédé et appareil de radiomessagerie, qui sont utilisés pour empêcher un dispositif terminal de recevoir un message de radiomessagerie invalide. Le procédé comprend les étapes suivantes : après qu'un premier dispositif de réseau détermine le type de message de radiomessagerie d'un premier message de radiomessagerie d'un dispositif terminal de radiomessagerie, le type de message de radiomessagerie du premier message de radiomessagerie peut être indiqué au dispositif terminal, ce qui permet au dispositif terminal de déterminer, selon le type de message de radiomessagerie indiqué par le premier dispositif de réseau, s'il faut recevoir le premier message de radiomessagerie. Lorsque le dispositif terminal détermine, en fonction du type du message de radiomessagerie du premier dispositif de réseau, de ne pas recevoir le premier message de radiomessagerie, la consommation d'énergie du dispositif terminal peut être efficacement réduite.
