Abstract:
A method for controlling a protocol data unit session in a wireless communication system, and an apparatus for same are disclosed. Particularly, a method by which a session management function (SMF) controls a protocol data unit (PDU) session for a low latency service in a wireless communication system can comprise the steps of: receiving a PDU session-related request from a user equipment (UE); determining whether the PDU session-related request is a request for the low latency service; and transmitting, to the UE, a response message to the PDU session-related request when the PDU session-related request is the request for the low latency service, wherein the response message includes low latency information on a PDU session related to the PDU session-related request.
