L'invention concerne un procédé et un dispositif de communication sans fil. Le procédé comprend les étapes suivantes : un dispositif terminal acquiert des informations de commande d'accès unifié (UAC) cibles correspondant à une tranche de réseau cible ; et d'après les informations UAC cibles, le dispositif terminal détermine des informations UAC pour le dispositif terminal et/ou détermine s'il faut accéder à un réseau. D'après la solution technique, différentes informations UAC peuvent être utilisées pour des exigences de commande d'accès de différentes tranches de réseau, ce qui permet d'éviter le problème selon lequel des informations UAC déterminées d'après un identifiant d'accès ne peuvent pas satisfaire une exigence de commande d'accès d'une tranche de réseau. Par conséquent, la précision de commande d'accès pour la tranche de réseau peut être améliorée.
