Abstract

L'invention concerne un procédé de commutation optimal prenant en charge une pluralité de connexions PDN, et un nœud de réseau correspondant. Le procédé comprend : pour chaque connexion PDN établie par un équipement utilisateur UE utilisant le même nom de point d'accès (APN), l'envoi, par une passerelle de dessertet HSGW à une passerelle PDN, d'un message de demande d'informations de clé d'encapsulation de routage générique (GRE KEY) correspondant à la connexion PDN; après que la passerelle PDN a reçu le message de demande, l'envoi, dans un message de réponse retourné à la HSGW, des informations GRE KEY correspondant à la connexion PDN; et après que la HSGW a reçu le message de réponse, l'enregistrement des informations GRE KEY correspondant à la connexion au PDN.
