Summary:An operation method of an AMF in a wireless communication system according to the present disclosure may comprise the steps of: receiving a message based on primary authentication from a terminal, the message including one of a SUCI and a 5G-GUTI; transmitting, to an AUSF, an authentication request message including the SUCI or a SUPI serving network name on the basis of the message; and receiving an authentication response message from the AUSF, wherein, when the terminal is roaming and AKMA is supported, the authentication response message comprises an AKMA anchor key and an A-KID indicating the AKMA anchor key, and the AMF performs a procedure of registering the AKMA anchor key with an AAnF on the basis of a SUPI, the AKMA anchor key, and the A-KID. La présente invention concerne un procédé de fonctionnement d'une AMF dans un système de communication sans fil, qui peut comprendre les étapes consistant à : recevoir un message sur la base d'une authentification primaire en provenance d'un terminal, le message comprenant soit une SUCI, soit une 5G-GUTI ; transmettre, à une AUSF, un message de demande d'authentification comprenant la SUCI ou un nom de réseau desservant une SUPI sur la base du message ; et recevoir un message de réponse d'authentification en provenance de l'AUSF, lorsque le terminal est en itinérance et que l'AKMA est prise en charge, le message de réponse d'authentification comprenant une clé d'ancrage AKMA et un A-KID indiquant la clé d'ancrage AKMA, et l'AMF effectuant une procédure d'enregistrement de la clé d'ancrage AKMA avec une AAnF sur la base d'une SUPI, de la clé d'ancrage AKMA et de l'A-KID. 본 개시는 무선 통신 시스템에서 AMF의 동작 방법에 있어서, 단말로부터 1차 인증에 기초한 메시지를 수신하는 단계로서, 메시지는 SUCI 또는 5G-GUTI 중 어느 하나를 포함하고, 메시지에 기초하여 SUCI 또는 SUPI 서빙 네트워크 네임을 포함하는 인증 요청 메시지를 AUSF로 전송하는 단계 및 AUSF로부터 인증 응답 메시지를 수신하는 단계를 포함하되, 단말이 로밍된 단말이고 AKMA가 지원되는 경우, 인증 응답 메시지는 AKMA 앵커 키 및 AKMA 앵커 키를 지시하는 A-KID를 포함하고, AMF는 SUPI, AKMA 앵커 키 및 A-KID에 기초하여 AAnF로 AKMA 앵커 키 등록 절차를 수행할 수 있다.
