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

Claim 13:
14. A network node configured for operation in a communication network, the network node comprising:
interface circuitry configured to communicatively couple the network node with an Application Server (AS) that supports one or more application services used by a communication device that communicatively couples with the AS via a first network slice provided by the communication network; and
processing circuitry that is operatively associated with the interface circuitry and configured to implement a Network Exposure Function (NEF) in the communication network, the NEF configured to:
determine that the communication device is compromised, based on detecting a device anomaly regarding the communication device, the device anomaly being an anomalous state or behavior of the communication device, or based on receiving signaling incoming from the AS, indicating that the communication device is compromised; and
responsive to determining that the communication device is compromised, initiate quarantine operations to move the communication device from the first network slice to a second network slice, for management of the communication device as a compromised device, the second network slice referred to as a quarantine network slice and the quarantine operations including sending a request to a Network Slice Selection Function (NSSF), to initiate re-registration of the communication device with the communication network, for re-connection of the communication device to the communication network via the quarantine network slice.
