Abstract: front page image
(EN)The present disclosure relates to a specific method for changing a connection state of a terminal and an apparatus therefor. More specifically, the present disclosure relates to technology for, when an S1 connection release event occurs in a core network, releasing an RRC connection state of a terminal which is in a light connection state or an RRC-inactive state. One embodiment provides a method for changing a connection state by a terminal, and an apparatus therefor, the method comprising the steps of: configuring a connection state of a terminal as a particular RRC state on the basis of indication information which indicates a state change to a particular RRC state and is received from an anchor base station; receiving, from the anchor base station or a serving base station, an RAN initiation paging message generated due to an S1 connection release of the terminal; transmitting an RRC connection resumption request message for a state change from the particular RRC state to an RRC connection state on the basis of the RAN initiation paging message; and when the state of the terminal is changed to the RRC connection state, receiving an RRC connection release request message from the anchor base station or the serving base station, wherein the particular RRC state is a state that is neither the RRC connection state nor the RRC idle state.
(FR)La présente invention concerne un procédé spécifique pour changer un état de connexion d'un terminal, et un appareil associé. Plus spécifiquement, la présente invention concerne une technologie pour, lorsqu'un événement de libération de connexion S1 se produit dans un réseau central, libérer un état de connexion RRC d'un terminal qui est dans un état de connexion lumineuse ou un état RRC inactif. Un mode de réalisation de l’invention concerne un procédé de changement d'un état de connexion par un terminal, et un appareil associé. Le procédé comprend les étapes consistant à : configurer un état de connexion d'un terminal en tant qu'un état RRC particulier sur la base d'informations d'indication qui indiquent un changement d'état à un état RRC particulier et sont reçues d'une station de base d'ancrage ; recevoir, de la station de base d'ancrage ou d'une station de base de desserte, un message de radiomessagerie d'initiation de RAN généré en raison d'une libération de connexion S1 du terminal ; transmettre un message de demande de reprise de connexion RRC pour un changement d'état de l'état RRC particulier à un état de connexion RRC sur la base du message de radiomessagerie d'initiation de RAN ; et lorsque l'état du terminal change à l'état de connexion RRC, recevoir un message de demande de libération de connexion RRC, de la station de base d'ancrage ou de la station de base de desserte, l'état RRC particulier étant un état qui n'est ni l'état de connexion RRC ni l'état de veille RRC.
(KO)본 개시는 단말의 연결 상태를 변경하는 구체적인 방법 및 그 장치에 관한 것이다. 보다 상세하게는 라이트 커넥션 또는 RRC inactive 상태의 단말에 대해서 코어망의 S1 연결 해제 이벤트 발생 시에 단말의 RRC 연결 상태를 해제하기 기술에 관한 것이다. 일 실시예는 단말이 연결 상태를 변경하는 방법에 있어서, 앵커 기지국으로부터 수신되는 특정 RRC 상태로의 상태 변경을 지시하는 지시정보에 기초하여, 단말의 연결 상태를 특정 RRC 상태로 구성하는 단계와 앵커 기지국 또는 서빙 기지국으로부터 단말의 S1 연결 해제를 원인으로 하는 RAN 개시 페이징 메시지를 수신하는 단계와 RAN 개시 페이징 메시지에 기초하여 특정 RRC 상태에서 RRC 연결 상태로의 상태 변경을 위한 RRC 연결 재개 요청 메시지를 전송하는 단계 및 RRC 연결 상태로 변경되면, 앵커 기지국 또는 서빙 기지국으로부터 RRC 연결 해제 요청 메시지를 수신하는 단계를 포함하되, 특정 RRC 상태는 RRC 연결(Connection) 상태 및 RRC 유휴 상태와 구분되는 상태인 것을 특징으로 하는 방법 및 장치를 제공한다.
