Abstract

L'invention concerne un procédé de gestion de l'accès au réseau et un terminal mobile. Le procédé selon l'invention comprend les étapes suivantes : un terminal mobile détecte un élément d'informations de gestion d'accès relatif à une interdiction dans un message système diffusé, et détermine si l'accès au réseau est interdit au terminal mobile sur la base de l'élément d'informations de gestion d'accès relatif à une interdiction ; si l'accès au réseau est interdit au terminal mobile, un temporisateur de retrait est activé ; et lorsque le temporisateur de retrait expire, le terminal mobile lance un processus de recherche d'un second réseau prioritaire dans une couche inférieure pour obtenir un service réseau normal. Lorsque dans un environnement de réseaux en parallèle et collaboratifs il se produit une défaillance dans un réseau, ou lorsqu'un système réseau est surchargé, le procédé et le terminal mobile permettent à un terminal mobile à faible priorité d'accéder à un réseau dès que possible dans un tel environnement de réseau afin d'obtenir un service réseau normal, ce qui permet de réduire la charge d'un système de réseau, d'améliorer l'expérience de l'utilisateur et d'assurer une longue durée de batterie au terminal mobile.
