Abstract

L'invention concerne un procédé, un dispositif et un système de transmission de données qui sont utilisés pour résoudre le problème courant de surcharge importante de signalisation de système, existant dans une configuration de groupes d'AP. Le procédé d'un côté réseau comprend : un dispositif réseau recevant des informations concernant un premier point d'accès (AP), qui sont rapportées par un terminal et satisfont à une condition déterminée; et le dispositif réseau configurant un premier groupe de points d'accès (AP) pour le terminal selon les informations concernant le premier AP, de sorte que le terminal utilise un AP dans le premier groupe d'AP pour accéder à un réseau. Dans les modes de réalisation de la présente invention, un dispositif réseau configure dynamiquement un premier groupe d'AP pour un terminal conformément aux informations concernant un premier AP rapportées par le terminal et satisfaisant à une condition déterminée, de sorte que des AP inclus dans le premier groupe d'AP configuré peuvent être plus acceptables. Etant donné que le premier groupe d'AP est optimisé, le nombre des AP inclus dans le premier groupe d'AP est également réduit en comparaison avec le nombre des AP inclus dans un groupe d'AP déterminé par l'état antérieur de la technique, ce qui permet de réduire la surcharge de configuration de signalisation.
