The invention relates to a method, by a gateway controller (100), to select a gateway (200) from a plurality of gateways (200a-i) for a data packet flow in a mobile communications network, the gateway being selected for applying a service to the data packet flow. The method comprises a step in which service data is received from the plurality of gateways, the service data including information which at least one service the corresponding gateway is able to apply to the data packet flow. The service data for the plurality of gateways (200a-i) is stored in a service list (70) where it is stored for each of the plurality of gateways, which at least one service the corresponding gateway is able to provide. Furthermore, data indicating an unavailability which indicate which at least one service is not available at the corresponding gateway is received from the plurality of gateways (200a-i). A request is received to select one gateway from the plurality of gateways for the data packet flow to which the service has to be applied. One of the plurality of gateways (200a-i) is selected for the data packet flow based on the service list and based on the data indicating an unavailability so that the service is applied to the data packet flow at the selected gateway. |
