Abstract

Selon des modes de réalisation, la présente demande concerne un procédé de traitement d'informations de mobilité, une station de base et un dispositif de gestion de mobilité. Selon un aspect, avant qu'un terminal ne passe à un état de veille depuis un premier état de connexion, une station de base envoie des informations de mobilité, indiquant que le terminal est dans le premier état de connexion, à un dispositif de gestion de mobilité, de manière que, lorsque le terminal passe à un second état de connexion depuis l'état de veille, la station de base puisse recevoir les informations de mobilité indiquant que le terminal est dans le premier état de connexion et envoyées par le dispositif de gestion de mobilité, ce qui permet de résoudre un problème dans l'état antérieur de la technique selon lequel la station de base ne peut pas obtenir les informations de mobilité indiquant que le terminal est dans l'état de connexion, dû au fait qu'après que le terminal est repassé à l'état de connexion depuis l'état de veille, la station de base supprime les informations de mobilité indiquant que le terminal est dans l'état de connexion et obtenues par la station de base, de sorte qu'après la passage du terminal à l'état de connexion depuis l'état de veille, la station de base obtient les informations de mobilité avant que le terminal ne soit dans l'état de veille.
