Abstract

La présente demande divulgue un procédé de commande de liste blanche dans un système de communication Beidou, ainsi qu'un dispositif associé. La présente demande se rapporte au domaine des communications par satellite. Lors de la réception d'un premier message court envoyé par un second terminal à un premier terminal dans le réseau Beidou, un dispositif de réseau Beidou peut déterminer, sur la base d'une liste blanche stockée du premier terminal, si la liste blanche du premier terminal comprend l'identifiant du second terminal ; si le dispositif de réseau Beidou détermine que la liste blanche du premier terminal comprend l'identifiant du second terminal, le dispositif de réseau Beidou stocke le premier message court ; et si le dispositif de réseau Beidou détermine que la liste blanche du premier terminal ne comprend pas l'identifiant du second terminal, le dispositif de réseau Beidou rejette le premier message court. De cette manière, le dispositif de réseau Beidou peut seulement recevoir et transmettre le message court envoyé par le terminal dans la liste blanche, ce qui fait en sorte qu'un espace de stockage et des ressources de transmission d'interface radio d'un système de communication Beidou sont économisés et que la consommation d'énergie du premier terminal pour recevoir le message court est réduite.
