(KO) 무선 통신 시스템에서 회선 교환 서비스 제공 방법 및 장치
Abstract: front page image
(EN)Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety related services, and the like) on the basis of 5G communication technology and IoT related technologies. The present invention relates to a method by which a terminal receives a circuit switching (CS) service, and according to the present invention, the method by which a terminal receives a CS service, comprises the steps of: transmitting a CS fallback (CSFB) request to a mobility management entity (MME) through a first base station in order to use the CS service; detecting the failure of a radio resource connection to the first base station; and transmitting, to a second base station, a radio resource re-establishment related message including a CSFB identifier for identifying the CSFB request.
(FR)L'invention concerne une technique de communication pour fusionner un système de communications 5G avec une technologie IoT, pour permettre la prise en charge d'un débit de transmission de données supérieur à celui d'un système 4G. L'invention concerne également un système associé. La présente invention peut être appliquée à des services intelligents (par exemple une habitation intelligente, un bâtiment intelligent, une ville intelligente, une voiture intelligente ou une voiture connectée, des soins de santé, l'enseignement numérique, le commerce de détail, les services liés à la sécurité et à la sûreté, etc.) sur la base d'une technologie de communication 5G et de technologies liées à l'IoT. La présente invention concerne un procédé par lequel un terminal reçoit un service à commutation de circuits (CS) et, selon la présente invention, le procédé par lequel un terminal reçoit un service CS comprend les étapes consistant à : transmettre une demande de repli CS (CSFB) à une entité de gestion de mobilité (MME) par l'intermédiaire d'une première station de base afin d'utiliser le service CS; détecter l'échec d'une connexion de ressource radio à la première station de base; et transmettre, à une seconde station de base, un message associé à un rétablissement de ressource radio contenant un identifiant CSFB pour identifier la demande CSFB.
(KO)본 개시는 4G 시스템 이후 보다 높은 데이터 전송률을 지원하기 위한 5G 통신 시스템을 IoT 기술과 융합하는 통신 기법 및 그 시스템에 관한 것이다. 본 개시는 5G 통신 기술 및 IoT 관련 기술을 기반으로 지능형 서비스 (예를 들어, 스마트 홈, 스마트 빌딩, 스마트 시티, 스마트 카 혹은 커넥티드 카, 헬스 케어, 디지털 교육, 소매업, 보안 및 안전 관련 서비스 등)에 적용될 수 있다. 본 발명은 단말의 회선 교환 서비스 수신 방법에 관한 것으로, 본 발명에 따른 단말의 회선 교환 서비스 수신 방법은, 회선 교환(circuit switching: CS) 서비스를 이용하기 위해 CS fallback(CSFB) 요청을 제1 기지국을 통해 이동성 관리 엔티티(mobility management entity: MME)로 전송하는 단계, 상기 제1 기지국과의 무선 자원 연결 실패를 감지하는 단계, 상기 CSFB 요청을 식별하기 위한 CSFB 식별자를 포함한 무선 자원 재수립 관련 메시지를 제2 기지국에 전송하는 단계를 포함하는 것을 특징으로 한다.
