Claim 15:
16. A network node comprising:
processing circuitry and memory, the memory containing instructions executable by the processing circuitry whereby the network node is configured to:
exchange, with a Session Management Function (SMF) comprised in a control plane of a core network of a wireless communication network supporting wireless communication and from an external network outside of the core network, Extensible Authentication Protocol (EAP) messages to authenticate a User Equipment (UE) in a secondary authentication process that uses the SMF as an EAP authenticator, the UE being separately authenticated with a further network node in the control plane of the core network via a primary authentication process; and
authorizing a data session, through a user plane of the core network and to the external network, that requires successful authentication of the UE via both the primary authentication process and the secondary authentication process.
