Abstract

Des modes de réalisation de la présente divulgation concernent un procédé de contrôle d'admission. Le procédé est exécuté par un terminal. Le procédé consiste, en fonction du résultat d'acquisition de l'acquisition d'un premier message de système prédéterminé, à déterminer qu'un terminal d'un type prédéterminé est autorisé ou non autorisé à accéder à une cellule. Ici, étant donné que le terminal peut déterminer, en fonction du résultat d'acquisition par rapport au premier message système, que le terminal du type prédéterminé est autorisé ou non à accéder à la cellule, le terminal prédéterminé peut déterminer, en fonction d'une indication du résultat d'acquisition, qu'un réseau permet ou ne permet pas au terminal du type prédéterminé d'accéder à la cellule ; et lorsqu'il est déterminé que le réseau permet au terminal du type prédéterminé d'accéder à la cellule, le terminal accède à la cellule. Par comparaison avec des procédés dans lesquels il ne peut pas être déterminé si le réseau permet au terminal du type prédéterminé d'accéder à la cellule, la présente invention peut améliorer la fiabilité d'accès du terminal du type prédéterminé, à la cellule.
