Abstract

La présente demande se rapporte au domaine des communications. Un procédé et un appareil de communication sont divulgués. Le procédé comprend les étapes suivantes : un dispositif de l'Internet des Objets détermine un objet auquel le dispositif de l'Internet des Objets envoie un message de l'Internet des Objets, l'objet étant sélectionné selon un type d'accès sans fil que le dispositif de l'Internet des Objets, une entité de gestion de l'Internet des Objets et une entité de passerelle de l'Internet des Objets prennent en charge ; et le dispositif de l'Internet des Objets envoie le message de l'Internet des Objets à l'objet. Ainsi, le problème selon lequel un mode d'envoi d'un message de l'Internet des Objets entraîne facilement un gaspillage de ressources de communication dans un scénario dans lequel un dispositif de l'Internet des Objets, une entité de gestion de l'Internet des Objets et une entité de passerelle de l'Internet des Objets sont tous dans une plage de communication directe est résolu.
