Abstract

Les modes de réalisation de la présente divulgation concernent un procédé d'intégration, un appareil de communication, un support et une puce. Dans les modes de réalisation de la présente divulgation, le procédé comprend les étapes suivantes : un dispositif de réseau central reçoit un premier message en provenance d'un dispositif de réseau d'accès, le premier message comprenant un identifiant de cellule d'une première cellule du dispositif de réseau d'accès devant faire l'objet d'un accès par un dispositif terminal ; en fonction de l'identifiant de cellule de la première cellule, le dispositif de réseau central détermine que la première cellule ne prend pas en charge l'intégration ; et le dispositif de réseau central commande l'accès du dispositif terminal à la première cellule. Au moyen de la prise en considération d'une capacité d'intégration d'une cellule, les restrictions sur l'accès aux cellules peuvent être réalisées sur un côté réseau central sans avoir besoin de changer un mécanisme de sélection de cellule sur un côté de dispositif terminal. De cette manière, la charge d'une cellule commune peut être efficacement réduite, et les performances et la sécurité du réseau peuvent être améliorées.
