Zusammenfassung:According to an embodiment of the present disclosure, in a method for managing registration of a network slice in a wireless communication system, an access and mobility management function (AMF) determines the update of a slice for a terminal, identifies a first access type applied to network slice admission control (NSAC) when the NSAC is applied to the slice, requests confirmation of availability for the slice from a network slice admission control function (NSACF) when a second access type applied to the permitted slice to update the slice is the same as the identified first access type, and updates the permitted slice of the terminal based on a received response according as the response to the request is received. Therefore, the present invention can effectively manage the network slice registered for the terminal in the wireless communication system. 본 개시의 일 실시예에 따른 무선 통신 시스템에서 네트워크 슬라이스의 등록을 관리하는 방법에 있어서, AMF(access and mobility management function)는 단말에 대한 슬라이스의 업데이트를 결정하고, 슬라이스에 NSAC(network slice admission control)가 적용되는 경우, NSAC에 적용되는 제 1 액세스 타입을 식별하며, 슬라이스를 업데이트할 허용 슬라이스에 적용되는 제 2 액세스 타입이 식별된 제 1 액세스 타입과 동일한 경우, NSACF(network slice admission control function)에 슬라이스에 대한 이용가능성의 확인을 요청하고, 요청에 대한 응답이 수신됨에 따라, 수신된 응답에 기초하여, 단말의 허용 슬라이스를 업데이트할 수 있다.
