Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 3:
4. A core network node for enabling handling of data packets in a wireless communication system, the core network node being comprised in a core network of the wireless communication system, the core network node being configured to:
identify a potentially malicious service data flow associated with a communication device served by an access network of the wireless communication system;
assign, to the potentially malicious service data flow, an identifier value that indicates that data packets associated with the potentially malicious service data flow is to be handled according to a packet handling rule for potentially malicious data packets; and to
provide the identifier value towards the communication device, towards at least one of:
an access node that serves the communication device in the access network, and
a second core network node that processes data packets to and from the communication device,, wherein the identifier value indicates at least one of:
that data packets associated with the potentially malicious service data flow is to be dropped by at least one of the communication device and the access node;
that data packets associated with the potentially malicious service data flow is to be monitored within the access network;
that the communication device associated with the potentially malicious service data flow is to be deprioritized by the access node;
that network resources for the communication device associated with the potentially malicious service data flow is to be restricted by the access node; and
wherein the identifier value implicitly indicates that data packets belonging to the potentially malicious service data flow is to be dropped or monitored.
