Method and apparatus for transmitting and receiving data in wireless communication system

A method of performing communication, by a session management function (SMF), in a wireless communication system, the method comprising:

• receiving subscription information including a network exposure function (NEF) identifier (ID) for non-internet protocol data delivery (NIDD), based on a protocol data unit (PDU) session establishment procedure;
• transmitting a message for connection request including information regarding NIDD configuration for a user equipment (UE), to a NEF corresponding to the NEF ID;
• and
• in case that a message for requesting the NIDD configuration is received at the NEF from an application function (AF) and NEF PDU session context is created based on the message for requesting the NIDD configuration at the NEF, receiving a message for connection response, from the NEF,
• wherein the message for requesting the NIDD configuration is received at the NEF as a response to a message for triggering the NIDD configuration, and
• wherein the message for triggering the NIDD configuration is transmitted from the NEF to the AF, in case that a NIDD configuration procedure for the UE between the NEF and the AF is not performed previously.

A network exposure function (NEF) for performing communication in a wireless communication system, the NEF comprising:

• a transceiver;
• and
• at least one processor configured to:
• receive, via the transceiver, a message for connection request including information regarding non-internet protocol data delivery (NIDD) configuration for a user equipment (UE) from a session management function (SMF),
• in case that a NIDD configuration procedure for the UE between the NEF and an application function (AF) is not performed previously, transmit, via the transceiver, a message for triggering the NIDD configuration to the AF, based on the information regarding the NIDD configuration included in the message for the connection request,
• receive, via the transceiver, a message for requesting the NIDD configuration from the AF, as a response to the message for the triggering the NIDD configuration,
• create NEF protocol data unit (PDU) session context, based on the received message for requesting the NIDD configuration, and
• transmit, via the transceiver, a message for connection response to the SMF, based on the received message for requesting the NIDD configuration.
