Abstract
The present disclosure relates to a communication technique that combines a 5G communication system for supporting a higher data transmission rate than a 4G system with IoT technology, and a system therefor. The present disclosure may be applied to intelligent services (e.g. smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. A method performed by a session management function (SMF) entity in a communication system, according to one embodiment of the present disclosure, may comprise the steps of: performing a packet data unit (PDU) session establishment procedure; identifying a QoS flow generated for ultra reliable low latency communication (URLLC) in a PDU session; identifying whether an indicator indicating that the PDU session is an Always-on PDU Session has ever been transmitted to a terminal; and when it is identified that the indicator has not been transmitted to the terminal, transmitting the indicator to the terminal.
