A method and a GGSN support node for sending data packets to a mobile station (MS) in a mobile communications system (13) from an external communication system (11, 12). The GGSN receives data packets from the external communication system (11, 12) in a first plurality of data flows which it maps to a second plurality of data flows in the mobile communications system (13). It establishes at least one filter (FI) for controlling the mapping and associates the filter (FI) with the mobile station. It also maps at least one of the data flows on the basis of the filter (FI) and configures the filter (FI) on the basis of information (6-1, 7-1) which preferably originates from the mobile station (MS).

L'invention concerne un procédé et un noeud de support GGSN permettant l'envoi de paquets de données à une station mobile (MS) d'un système de communication mobile (13), depuis un système de communication externe (11, 12). Le GGSN reçoit des paquets de données en provenance du système de communication externe (11, 12) dans une pluralité de trains de données qu'il met en correspondance avec une deuxième pluralité de trains de données dans le système de communication mobile (13). Il établit au moins un filtre (FI) pour commander le mappage et associe le filtre (FI) à la station mobile. Il mappe également au moins un des trains de données en fonction du filtre (FI) et configure ce dernier (FI) en fonction d'informations (6-1, 7-1) provenant de préférence de la station mobile (MS).
