Abstract

L'invention concerne un procédé et un appareil pour accéder à un système de communication sans fil, ainsi qu'un terminal. Le procédé comprend les opérations suivantes : un terminal utilise des informations de module d'identité d'abonné virtuel (V-SIM) pour demander un enregistrement dans un système de communication sans fil dans une période de temps de communication préréglée, les informations de V-SIM étant des informations de SIM utilisées et partagées par une pluralité de terminaux comprenant le terminal, et la période de temps de communication préréglée et des périodes de temps de communication des autres terminaux dans la pluralité de terminaux étant mutuellement exclusives ; et le terminal accède au système de communication sans fil dans la période de temps de communication préréglée où l'enregistrement réussit. Au moyen de la présente invention, le problème de coûts élevés provoqué en raison du fait que des dispositifs de l'Internet des objets utilisent respectivement des SIM indépendants pour accéder à un système de communication sans fil, est résolu, et le coût de l'utilisation des dispositifs de l'Internet des objets est réduit.
