1. :

  • A method for protecting a mobile communication network from performance impacts, wherein the mobile communication network comprises an access network and a core network, the access network comprising a plurality of radio cells and a plurality of base station entities, and the core network comprising a plurality of network nodes of the mobile communication network, wherein a user equipment is located in a radio cell of the plurality of radio cells, the radio cell being served by a base station entity of the plurality of base station entities, wherein the user equipment is able to be either in an idle state or in an activated state, wherein the user equipment is represented by a specific IP-address or a specific range of IP-addresses, wherein the core network comprises a filter element, wherein the method comprises;

    determining, by the filter element, whether to apply a forwarding functionality or an alternative treatment functionality for downlink data packets directed to the specific IP-address or to the specific range of IP-addresses of the user equipment, wherein the application of the forwarding functionality versus the alternative treatment functionality of the filter element is based on load conditions of the mobile communication network at a reception time of the downlink data packets at the core network; and

    providing the forwarding functionality or the alternative treatment functionality for the downlink data packets directed to the specific IP-address or to the specific range of IP-addresses of the user equipment;

    wherein at a given load condition of the mobile communication network, the forwarding functionality is applied for a particular downlink data packet if at least one of the following conditions are met;

    the filter element comprises information that the user equipment is in the activated state;

    a preceding downlink data packet, preceding the particular downlink data packet in time and being directed to the specific IP-address or to the specific range of IP-addresses of the user equipment, has been forwarded to the user equipment, wherein the preceding downlink data packet precedes the particular downlink data packet by less than a predetermined first time interval;

    a preceding uplink data packet, preceding the particular downlink data packet in time and originating from the specific IP-address or from the specific range of IP-addresses of the user equipment, has been received, by the filter element, from the user equipment, wherein the preceding uplink data packet precedes the particular downlink data packet by less than a predetermined second time interval; and

    wherein at the given load condition of the mobile communication network, the alternative treatment functionality is applied for a articular downlink data packet if none of the foregoing conditions are met.
