Abstract
The present disclosure relates to methods and devices for mitigating the impact from Internet attacks in a Radio Access Network, RAN (10), using Internet transport. This object is obtained by a method performed in in a User Equipment, UE (13) associated with the RAN (10) using Internet transport. The method comprises receiving from at least a network node (11, 12, 21, 22, 23) in the RAN (10), information associated with an Internet attack. Obtaining, based on the information, a mitigation action, the mitigation action mitigating the impact of the attack on the RAN service. The method further comprises to perform the obtained mitigation action to mitigate the impact on the RAN service level.

37. A method, performed in a network node in a Radio Access Network (RAN) using Internet transport, of mitigating impacts from Internet attacks, the method comprising:
-
obtaining intrusion detection information informing the network node that the RAN is under an Internet attack; selecting, based on the intrusion detection information, a mitigation action, wherein the mitigation action comprises sending a message comprising information associated with the Internet attack to a User Equipment (UE) connected to the RAN; and performing the selected mitigation action to mitigate the impact on the RAN service level. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47)

63. A non-transitory computer-readable storage medium, having stored thereupon a computer program that, when run in a network node in a Radio Access Network (RAN) using Internet transport, causes the network node to:
-
obtain intrusion detection information informing the network node that the RAN is under an Internet attack; select, based on the intrusion detection information, a mitigation action, wherein the mitigation action comprises sending a message comprising information associated with the internet attack to a User Equipment (UE) connected to the RAN; and perform the selected mitigation action to mitigate the impact on the RAN service level.
