Abstract: front page image
(EN)Provided are a mobile communication system, a communication control device, a mobile management entity, and a mobile communication method which are capable of avoiding failures in voice communication via IMS in cases when a mobile station is connected to a VPLMN. A HSS 100 determines whether roaming of voice communication via IMS 500 is supported on a VPLMN, and transmits, to an MME 300, a signal including the indicator "voice supported" or the indicator "voice not supported" which indicate whether said roaming is supported. The MME 300 receives the indicator from the HSS 100, and transmits, to a UE 20, an "Attach Accept" for an "Attach Request" from the UE 20 to the VPLMN. The MME 300 transmits, to the UE 20, the "Attach Accept" including an indicator indicating whether the roaming is supported, on the basis of the indicator received from the HSS 100.
(FR)L'invention concerne un système de communication mobile, un dispositif de commande de communication, une entité de gestion de mobilité, et un procédé de communication mobile. L'invention est apte à empêcher des échecs de communication vocale via un IMS lorsqu'une station mobile est connectée à un VPLMN. Un HSS 100 détermine si l'itinérance d'une communication vocale via un IMS 500 est prise en charge sur un VPLMN et transmet, à une MME 300, un signal contenant l'indicateur "voix prise en charge" ou l'indicateur "voix non prise en charge", qui indiquent si ladite itinérance est prise en charge. La MME 300 reçoit l'indicateur, du HSS 100, et transmet à un UE 20 une "Acceptation de rattachement" en réponse à une "Demande de rattachement" de l'UE 20 au VPLMN. La MME 300 transmet à l'UE 20 l'"Acceptation de rattachement" contenant un indicateur indiquant si l'itinérance est prise en charge, sur la base de l'indicateur reçu du HSS 100.
(JA)移動局がVPLMNに接続する場合にIMS経由の音声通信に失敗することを回避できる移動通信システム、通信制御装置、移動管理エンティティ及び移動通信方法を提供する。HSS100は、VPLMNにおいてIMS500経由による音声通信のローミングがサポートされているか否かを判定し、当該ローミングがサポートされているか否かを示すインジケータであるvoice supportedまたはvoice not supportedを含む信号をMME300に送信する。MME300は、HSS100から当該インジケータを受信しUE20からのVPLMNへのAttach Requestに対するAttach AcceptをUE20に送信する。MME300は、HSS100から受信したインジケータに基づいて、ローミングがサポートされているか否かを示すインジケータを含むAttach AcceptをUE20に送信する。
