## Abstract

The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate after a 4th generation (4G) communication system such as long-term evolution (LTE). According to various embodiments of the present disclosure, according to various embodiments of the present disclosure, an operating method of a network exposure function (NEF) in a wireless communication system is provided. The method includes receiving a Nnef_EventExposure_subscribe request message including a first non-subscription registration identifier (ID) from an application function (AF), transmitting a Namf_EventExposure_subscribe request message including the first non-subscription registration ID to a default unified data management (UDM), receiving a Namf_EventExposure_subscribe response message including a subscription correlation ID from the default UDM, transmitting a Nnef_EventExposure_subscribe response message including the subscription correlation ID to the AF, receiving a Namf_EventExposure_Notify message including a second non-subscription registration ID from the default UDM, and transmitting a Nnef_EventExposure_Notify message including the second non-subscription registration ID to the AF.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The method of claim 1,
wherein the non-subscription registration support indication is included in the PDU session establishment request message, and
wherein the SMF supports the EAP.

### Claim 3 (depends on 2)

The method of claim 2,
wherein information provided from the UE associated with the EAP indicates an un-authenticated state requiring the secondary authentication through the DN-AAA server.

### Claim 4

An apparatus of a session management function (SMF) in a wireless communication system, the apparatus comprising:
a transceiver; and
at least one processor operably coupled to the transceiver, and configured to:
receive, from an access & mobility management function (AMF), a protocol data unit (PDU) session establishment request message;
determine whether a secondary authentication through a data network authentication, authorization and accounting (DN-AAA) server is required based on information provided from a user equipment (UE) associated with an extensible authentication protocol (EAP), the information including a non-subscription registration support indication;
in case that the secondary authentication is required, identify the DN-AAA server;
perform the secondary authentication between the UE associated with the EAP and the identified DN-AAA server;
establish a PDU session in response to the secondary authentication which is successfully performed; and
transmit, to the AMF, a message notifying the establishment of the PDU session.

### Claim 5 (depends on 4)

The apparatus of claim 4,
wherein the non-subscription registration support indication is included in the PDU session establishment request message, and
wherein the SMF supports the EAP.

### Claim 6 (depends on 5)

The apparatus of claim 5,
wherein the information indicates an un-authenticated state requiring the secondary authentication through the DN-AAA server.
