Abstract

L'invention concerne un appareil comprenant au moins un processeur, ledit ou lesdits processeurs étant configurés pour faire en sorte que l'appareil fasse en sorte qu'une première demande d'enregistrement associée à une première identité d'abonné soit envoyée depuis un dispositif de communication. La première demande d'enregistrement comprend des informations indiquant qu'il s'agit d'une demande d'enregistrement pour le premier abonné d'un premier réseau en tant que réseau pour des services de communication. La première identité d'abonné est l'une d'une pluralité d'identités d'abonnés différentes associées au dispositif de communication. L'appareil est configuré pour recevoir une réponse, la réponse comprenant des informations indiquant que le premier réseau est enregistré en tant que réseau pour des services de communication pour la première identité d'abonné du dispositif de communication.
