Claim 8:
9. A session management function (SMF) in a wireless communication system, the SMF comprising:
a transceiver; and
at least one processor coupled with the transceiver, and configured to:
receive, from a user equipment (UE), a request for a quality of service (QoS) flow in a protocol data unit (PDU) session;
determine that the PDU session needs to be an always-on PDU session in case that the QoS flow in the PDU session is associated with an ultra-reliable low latency communication (URLLC) service and information associated with the PDU session that an always-on PDU session is required is not provided; and
transmit, to the UE, a PDU session modification command message including information indicating that the always-on PDU session is required, based on a result of the determination.
