1. A method of operating a session management function (SMF) in a wireless communication system, the method comprising:
receiving, from an access & mobility management function (AMF), a protocol data unit (PDU) session establishment request message including a non-subscription registration support indication provided from a user equipment (UE) associated with an extensible authentication protocol (EAP);
determining whether a secondary authentication through a data network authentication, authorization and accounting (DN-AAA) server is required based on the non-subscription registration support indication;
in case that the secondary authentication is required, identifying the DN-AAA server;
performing the secondary authentication between the UE associated with the EAP and the identified DN-AAA server;
establishing a PDU session in response to the secondary authentication which is successfully performed; and
transmitting, to the AMF, a message notifying the establishment of the PDU session.
