The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system, such as long-term evolution (LTE), and beyond. In a wireless communication system according to embodiments of the present disclosure, a method performed by a central unit-user plane (CU-UP) comprises the steps of: receiving information related to packet transmission from a user plane function (UPF), wherein the information related to packet transmission includes a provided quality of service (QoS) flow, a slice provided with the QoS flow, an indicator indicating a terminal provided with the QoS flow, and a time parameter related to latency quality measurement; identifying a quality measurement value on the basis of the received information related to packet transmission; updating the received information related to packet transmission on the basis of the identified quality measurement value; and transmitting the updated information related to packet transmission to a distributed unit (DU). La présente divulgation se rapporte à un système de communication de 5e génération (5G) ou pré-5G destiné à prendre en charge un débit de transmission de données supérieur à un système de communication de 4e génération (4G), tel qu'un système d'évolution à long terme (LTE) et au-delà. Dans un système de communication sans fil selon des modes de réalisation de la présente divulgation, un procédé mis en œuvre par un plan d'utilisateur d'unité central (CU-UP) comprend les étapes consistant : à recevoir des informations relatives à une transmission de paquets en provenance d'une fonction de plan d'utilisateur (UPF), les informations relatives à la transmission de paquets comprenant un flux de qualité de service (QoS) fourni, une tranche pourvue du flux QoS, un indicateur indiquant un terminal pourvu du flux QoS, et un paramètre temporel associé à une mesure de qualité de latence; à identifier une valeur de mesure de qualité en fonction des informations reçues relatives à la transmission de paquets; à mettre à jour les informations reçues relatives à la transmission de paquets en fonction de la valeur de mesure de qualité identifiée; et à transmettre les informations mises à jour relatives à la transmission de paquets à une unité distribuée (DU). 본 개시(disclosure)는 LTE(Long Term Evolution)와 같은 4G(4th generation) 통신 시스템, 그리고 이후 보다 높은 데이터 전송률을 지원하기 위한 5G(5th generation) 또는 pre-5G 통신 시스템에 관련된 것이다. 본 개시의 실시예들에 따른, 무선 통신 시스템에서, CU-UP(central unit-user plane)에 의하여 수행되는 방법은, UPF(user plane function)로부터 패킷 전송과 관련한 정보를 수신하는 단계, 상기 패킷 전송과 관련한 정보는 제공되는 QoS(quality of service) flow, 상기 QoS flow가 제공되는 슬라이스, 및 상기 QoS flow를 제공받는 단말을 지시하는 지시자 및 지연 품질 측정에 관한 시간 파라미터를 포함하고, 상기 수신한 패킷 전송과 관련한 정보에 기반하여 품질 측정 값을 식별하는 단계, 상기 식별된 품질 측정 값에 기반하여 상기 수신한 패킷 전송과 관련한 정보를 업데이트하는 단계, 및 상기 업데이트된 패킷 전송과 관련한 정보를 DU(distributed unit)에게 송신하는 단계를 포함하는 방법.
