Abstract

Un dispositif de communication détermine un schéma de partage de paramètres exécutable par un premier point d'accès fonctionnant en tant qu'agent multi-AP et exécute le schéma de partage de paramètres sur la base du résultat de détermination pour acquérir un paramètre de communication d'un réseau sans fil. En outre, le dispositif de communication détermine un schéma de partage de paramètres exécutable par un second point d'accès fonctionnant en tant que contrôleur multi-AP et exécute un traitement de partage de paramètres conjointement avec le second point d'accès sur la base du résultat de détermination pour acquérir des informations à utiliser lorsque le dispositif de communication fonctionne comme un agent multi-AP.
