Abstract

Des modes de réalisation de la présente invention concernent le domaine technique des réseaux, et concernent un procédé d'accès à une tranche de réseau. Le procédé comprend les étapes suivantes : une station de base envoie des premières informations de système à un équipement utilisateur à un premier emplacement temps-fréquence, les premières informations de système comprenant au moins un second emplacement temps-fréquence ; l'équipement utilisateur obtient le second emplacement temps-fréquence à partir des premières informations de système ; la station de base envoie des premières informations d'accès au réseau à l'équipement utilisateur au second emplacement temps-fréquence ; et l'équipement utilisateur accède à une première tranche de réseau conformément aux premières informations d'accès au réseau. Par le fait qu'un équipement utilisateur reçoit, à un emplacement temps-fréquence correspondant à un service cible, des premières informations d'accès au réseau envoyées par une station de base, la présente invention résout le problème selon lequel le mode de diffusion actuel n'est pas approprié pour un réseau 5G ayant une pluralité de tranches de réseau, et permet d'obtenir les effets selon lesquels le mode de diffusion est approprié pour le réseau 5G ayant une pluralité de tranches de réseau et selon lesquels l'équipement utilisateur peut accéder à des tranches de réseau devant faire l'objet d'un accès.
