Abstract

L'invention concerne un procédé et un dispositif de connexion à un réseau. Le procédé comporte les étapes suivantes: une station de base reçoit un message de demande signalé par un équipement d'utilisateur (UE) pour demander la réalisation d'une connexion à un réseau, le message de demande transportant des premières informations d'indication servant à indiquer que l'UE prend en charge une fonctionnalité de couplage serré multi-système; et la station de base envoie à l'UE, d'après le message de demande, un message de configuration pour que l'UE réalise la connexion au réseau, le message de configuration transportant des deuxièmes informations d'indication servant à indiquer que l'UE adopte une méthode de couplage serré multi-système pour réaliser la connexion au réseau. Au moyen de la présente invention, le problème rencontré dans la technique concernée, où un conflit de sélection de réseau dans un équipement d'utilisateur ne peut être évité est résolu, ce qui a pour effet d'éviter un conflit de sélection de réseau dans l'équipement d'utilisateur.
