Abstract

Afin de permettre un contrôle flexible de connexion à un réseau de communication d'un terminal de communication même lorsque des terminaux de communication présentant des exigences de demande différentes en termes de qualité de communication sont mélangés dans un réseau mobile, l'invention concerne un système de contrôle de communication qui contrôle la connexion d'un terminal de communication à un réseau de communication dans un réseau mobile, le système de contrôle de communication comprenant : une unité d'identification qui identifie le type du terminal de communication ou un service sur la base d'une demande de connexion du terminal de communication au réseau de communication; une unité de détermination qui collecte des métriques concernant le système de contrôle de communication et détermine une anomalie du système de contrôle de communication sur la base des métriques collectées; et une file d'attente de messages qui, sur la base du résultat d'identification produit par l'unité d'identification et du résultat de détermination produit par l'unité de détermination, contrôle la quantité de signal de communication mise en œuvre par le terminal de communication.
