Abstract

Le dispositif de communication sans fil s'enregistre (401) auprès d'un premier réseau de communication sans fil associé à un premier SIM en fournissant une ou plusieurs premières capacités. Lorsqu'il est connecté à un premier réseau de communication sans fil, le dispositif de communication sans fil transmet (403) une première demande au premier nœud de réseau pour désactiver un ensemble de capacités parmi la ou les premières capacités. Le dispositif de communication sans fil se connecte (404) à un second nœud de réseau d'un second réseau de communication sans fil associé à un second SIM, de sorte que le dispositif de communication sans fil est connecté au premier nœud de réseau avec des capacités réduites sans l'ensemble de capacités, et que le dispositif de communication sans fil est connecté au second nœud de réseau à l'aide de l'ensemble de capacités. Lorsque le dispositif de communication sans fil est déconnecté du second nœud de réseau, le dispositif de communication sans fil gère (405) une procédure de réactivation des capacités en : déclenchant une seconde demande au premier nœud de réseau pour réactiver l'ensemble de capacités selon qu'une première condition de déclenchement de la réactivation est satisfaite ou non, ou en ne déclenchant pas la seconde demande selon qu'une seconde condition de non-déclenchement de la réactivation est satisfaite ou non.
