Abstract

La présente invention concerne un procédé d'accès à un réseau et un dispositif ANDSF. Dans le procédé, lorsqu'un état de signal détecté satisfait une condition de rapport, un terminal mobile rapporte, à un dispositif ANDSF, un état de signal du réseau ayant fait actuellement l'objet d'un accès et des informations de position du terminal mobile ; et le dispositif ANDSF génère une nouvelle politique d'accès pour un utilisateur correspondant au terminal mobile selon l'état de signal et les informations de position du terminal mobile ; et envoie la nouvelle politique d'accès au terminal mobile. Par comparaison avec l'état de la technique dans lequel un dispositif ANDSF génère une politique d'accès selon la couverture de réseau fixe, dans des modes de réalisation de la présente invention, le dispositif ANDSF génère une politique d'accès en combinaison avec un état de signal d'une position à laquelle un terminal mobile est situé et permet au terminal d'effectuer un accès ; en conséquence, un réseau approprié peut être sélectionné de manière précise pour le terminal mobile selon la condition de couverture de réseau, et le taux de réussite d'accès du terminal mobile est élevé.
