Abstract

L'invention concerne un procédé et un dispositif d'acquisition d'informations de capacité de réseau. Le procédé comprend les étapes suivantes : une entité SCEF reçoit un premier message de demande de capacité de réseau envoyé par un serveur d'application, le premier message de demande de capacité de réseau portant une identification (ID) d'identité de serveur d'application, une identification externe d'UE et des informations d'indication de capacité de réseau ; et si l'entité SCEF détermine que le serveur d'application est autorisé à acquérir les informations de capacité de réseau demandées en fonction de l'ID de serveur d'application et les informations d'indication de capacité de réseau, l'entité SCEF envoie ensuite un second message de demande de capacité de réseau à un serveur d'abonné domestique (HSS), le second message de demande de capacité de réseau portant l'ID de serveur d'application, l'identification externe d'UE et les informations d'indication de capacité de réseau, de sorte que le HSS détermine l'opportunité de permettre au serveur d'application d'acquérir les informations de capacité de réseau demandées concernant un UE selon l'identification externe d'UE et l'ID de serveur d'application. Ainsi, un fournisseur de service peut obtenir des informations de capacité de réseau à l'aide du procédé, améliorant en outre la commodité du fournisseur de service fournissant un service à un abonné.
