  • Patent number: 10050992
    Abstract: The present disclosure relates to methods and devices for mitigating the impact from Internet attacks in a Radio Access Network, RAN, using Internet transport. This object is obtained by a method performed in network node in a Core network, CN, of mitigating the impact from Internet attacks in a Radio Access Network, RAN, using Internet transport. The method comprises receiving, from at least a network node in a Radio Access Network, RAN, an intrusion detection report, the intrusion detection report comprises information about an Internet attack in the RAN. The method further comprises selecting based on the information, a mitigation action, the mitigation action mitigating the impact of the attack on the RAN service level. Further the method comprises performing the selected mitigation action to mitigate the impact on the RAN service level.

  • Patent number: 9705900
    Abstract: The present disclosure relates to methods and devices for mitigating the impact from Internet attacks in a Radio Access Network, RAN, using Internet transport. This object is obtained by a method performed in network node in a RAN, using Internet transport. The method comprises obtaining intrusion detection information informing the network node that the RAN is under attack. The method further comprises selecting, based on the intrusion detection information, a mitigation action, the mitigation action mitigating the impact of the attack on the RAN service. Further the method comprises performing the selected mitigation action to mitigate the impact on the RAN service level.
