Abstract
(EN)
The present invention can provide a resource allocation method in a network in which a plurality of virtualized network functions (VNFs) are deployed and used in MEC servers serving as base stations, the method comprising the steps of : analyzing characteristics of a pre-designated user terminal and grouping a plurality of user terminals into at least one user group depending on the analyzed characteristics of the user terminal; determining the number of clusters such that an average service time of data flow is minimized for each of the at least one user group; clustering the network to the number of clusters determined for each of the at least one user group; and deploying the VNF required by the user terminal located in each of the clusters clustered for each user group in the MEC server included in a corresponding cluster.
(FR)
La présente invention concerne un procédé d'attribution de ressources dans un réseau dans lequel une pluralité de fonctions réseau virtualisées (VNF) sont déployées et utilisées dans des serveurs MEC servant de stations de base. Le procédé comprend les étapes consistant à : analyser des caractéristiques d'un terminal utilisateur pré-désigné, et grouper une pluralité de terminaux utilisateurs dans au moins un groupe d'utilisateurs d’après les caractéristiques analysées du terminal utilisateur ; déterminer le nombre de grappes de sorte à réduire au maximum un temps de service moyen d'un flux de données pour chacun du ou des groupes d'utilisateurs ; mettre le réseau en grappe par rapport au nombre de grappes déterminées pour chacun du ou des groupes d'utilisateurs ; et déployer la VNF requise par le terminal utilisateur situé dans chacune des grappes mises en grappe pour chaque groupe d'utilisateurs dans le serveur MEC inclus dans une grappe correspondante.

본 발명은 다수의 VNF (Virtualized Network Function)를 기지국을 겸하는 MEC 서버들에 배치하여 사용하는 네트워크에 있어서, 기지정된 사용자 단말의 특성을 분석하고, 분석된 사용자 단말의 특성에 따라 다수의 사용자 단말을 적어도 하나의 사용자 그룹으로 그룹화하는 단계, 상기 적어도 하나의 사용자 그룹 각각에 대해 데이터 플로우의 평균 서비스 시간이 최소화되도록 클러스터의 개수를 결정하는 단계, 상기 네트워크를 적어도 하나의 사용자 그룹별로 결정된 클러스터 개수로 클러스터링하는 단계 및 사용자 그룹별로 클러스터링된 클러스터 각각에 위치하는 사용자 단말에서 요구하는 VNF를 대응하는 클러스터에 포함된 MEC 서버에 배치하는 단계를 포함하는 자원 할당 방법을 제공할 수 있다.
