1. A method of performing communication, by a network exposure function (NEF), in a wireless communication system, the method comprising:
receiving, from a session management function (SMF), a request message for connection establishment including information regarding non-internet protocol data delivery (NIDD) configuration for a user equipment (UE);
in case that the request message for the connection establishment is received from the SMF, and the NIDD configuration for the UE is not set for the NEF and an application function (AF), performing a procedure for the NIDD configuration for the UE,
wherein the performing of the procedure for the NIDD configuration for the UE includes:
transmitting a message for triggering the procedure for the NIDD configuration for the UE to the AF, using the information regarding the NIDD configuration for the UE;
receiving a message for requesting the NIDD configuration for the UE from the AF, as a response to the message for triggering the procedure for the NIDD configuration for the UE;
transmitting a request message for authorization for the NIDD configuration for the UE to a unified data management (UDM);
receiving a response message for the authorization for the NIDD configuration for the UE from the UDM as a response to the request message for the authorization for the NIDD configuration for the UE; and
transmitting a message for responding the NIDD configuration for the UE to the AF, based on the response message for the authorization for the NIDD configuration for the UE, as a response to the message for requesting the NIDD configuration for the UE;
based on the performing of the procedure for the NIDD configuration for the UE, creating NEF protocol data unit (PDU) session context for the UE; and
based on the performing of the procedure for the NIDD configuration for the UE, transmitting a response message for the connection establishment to the SMF.
