Abstract

La présente invention concerne, dans certains modes de réalisation, un procédé et un dispositif pour afficher un nom de réseau. Lors d'un processus de connexion commun ou d'un processus de mise à jour de localisation de domaine de suivi commun, une entité de gestion de mobilité (MME) située dans un premier réseau détermine si oui ou non l'opérateur auquel appartient un identificateur de réseau mobile terrestre public (PLMN ID) correspondant au premier réseau est identique à l'opérateur auquel appartient un ID PLMN correspondant à un second réseau. S'il n'est pas identique, alors le MME transmet des informations de nom de réseau à l'équipement utilisateur, ce qui permet à l'équipement utilisateur d'afficher le nom de réseau correspondant aux informations de nom de réseau, le premier réseau et le second réseau étant des réseaux sur lesquels l'UE s'est conjointement enregistrée pendant le processus de connexion commun ou le processus de mise à jour de localisation de domaine de suivi commun, le premier réseau étant un réseau d'évolution à long terme (LTE), et le deuxième réseau étant un réseau 2G ou un réseau 3G. L'utilisation de cette solution technique permet de garantir que le nom de réseau affiché par un terminal correspond au nom de réseau qui est enregistré par un dispositif de réseau pour avoir été affiché par l'UE.
