Dans la solution technique d'après la présente invention, lorsque la première carte d'identification d'utilisateur a récupéré la ressource radiofréquence, une mise à jour de cellule est effectuée pour la première carte d'identification d'utilisateur, de sorte que l'état de communication de la première carte d'identification d'utilisateur est cohérent par rapport à l'état de communication du dispositif de réseau pour la première carte d'identification d'utilisateur, ce qui règle au mieux le problème des appels manqués dans certains scénarios.
