Abstract

La présente invention se rapporte au domaine technique de l'Internet des objets (IoT), et concerne spécifiquement un procédé et un système de commande de l'encapsulation de données dans un IoT. Le procédé comporte les étapes suivantes: un nœud de réacheminement reçoit une indication d'encapsulation de données émise par une unité de convergence, et détecte des données d'IoT, rapportées par des dispositifs terminaux massifs, dans sa plage de couverture sans fil; lorsque les données d'IoT rapportées par les dispositifs terminaux massifs ne se conforment pas à l'exigence d'encapsulation indiquée par l'indication d'encapsulation de données, le nœud de réacheminement acquiert le contenu de données manquant à partir d'un serveur de données correspondant, et encapsule le contenu de données acquis, accompagné des données d'IoT rapportées par les dispositifs terminaux massifs, en un élément de données; et envoie l'élément de données à l'unité de convergence. Les modes de réalisation de la présente invention peuvent rendre compte, selon les exigences spécifiques de l'unité de convergence, de données répondant aux exigences spécifiques, de façon à garantir l'intégrité des données reçues par l'IoT, améliorant ainsi le rendement de traitement de données de l'IoT.
