Abstract

L'invention concerne un procédé et un appareil de commutation de réseau, et un terminal. Le procédé consiste à : déterminer qu'un terminal ne peut pas exécuter un service de données au moyen d'un réseau d'évolution à long terme (LTE) ; surveiller des paramètres de service relatifs à un échec d'activation de service de données dans un réseau de données par paquets à haut débit évolué (EHRPD), avec les paramètres de service comprenant le nombre de fois où l'activation du service de données a échoué ou les raisons pour lesquelles l'activation du service de données a échoué ; déterminer si les paramètres de service remplissent une première condition, la première condition étant une condition prédéfinie pour que le terminal quitte le réseau EHRPD ; et, si les paramètres de service remplissent la première condition, quitter le réseau EHRPD et demander à accéder à un réseau HRPD de sorte que lorsqu'une carte 4G est insérée dans le terminal mais que le terminal ne peut pas accéder à un réseau 4G, le terminal peut accéder rapidement au réseau HRPD pour exécuter un service de données, ce qui améliore significativement les performances du terminal.
