Abstract

Les modes de réalisation de l'invention concernent un procédé et un appareil de commande d'accès réseau, ainsi qu'un dispositif et un support de stockage. Le procédé comprend les étapes suivantes : une cellule de desserte détermine les paramètres de commande d'accès à diffuser pour indiquer que la cellule de desserte autorise et/ou prend en charge et/ou bloque l'accès aux informations; puis les paramètres de commande d'accès sont diffusés au moyen d'un dispositif réseau auquel ceux-ci appartiennent; par conséquent, un dispositif terminal situé dans la cellule de desserte reçoit les paramètres de commande d'accès diffusés par la cellule de desserte; et en fonction des paramètres de contrôle d'accès, il est déterminé si le dispositif terminal est en mesure d'accéder à la cellule de desserte. Selon l'invention, la cellule de desserte met en œuvre la commande d'accès du dispositif terminal au moyen d'informations de diffusion prises en charge et/ou autorisées et/ou interdites, puis le dispositif terminal détermine s'il est capable d'accéder à la cellule de desserte d'après les paramètres de commande d'accès reçus en combinaison avec les informations de tranche associées, ce qui permet d'améliorer la précision avec laquelle l'accès aux cellules est contrôlé.
