Abstract

Les modes de réalisation de la présente invention concernent un système de réseau d'accès sans fil en nuage, un procédé de traitement de données, et un dispositif, appartenant au domaine des communications. L'invention est apte à s'adapter à plusieurs nœuds vREC en même temps, et à prendre en charge plusieurs nœuds vREC établissant des relations de session unique. L'invention comprend un nœud NFVI et un nœud vBTS; le nœud NFVI comprend un nœud RE AGENT; le nœud RE AGENT comprend au moins un premier nœud vRE; le nœud vBTS comprend un nœud vREC et un second nœud vRE; le second nœud vRE compris par le nœud vBTS fournit un index pour le premier nœud vRE compris par le nœud RE AGENT; le nœud NFVI est connecté au nœud vBTS au moyen d'une interface RE; le nœud vRE compris par le nœud vREC communique avec le nœud RE AGENT au moyen de l'interface RE. L'invention est utilisée pour établir une relation de session unique entre un vREC et un vRE.
