1. A method of a terminal in a wireless communication system, the method comprising:
transmitting, to a Session Management Function (SMF), a Protocol Data Unit (PDU) session modification request message, wherein the PDU modification request message includes information on a requested quality of service (QoS) rule; and
receiving, from the SMF, a PDU session modification command message as a response to the PDU session modification request message,
wherein the information on the requested QoS rule includes bit information on segregation and information on a precedence value of the requested QoS rule among at least one of QoS rule,
wherein the bit information on segregation indicates whether the terminal is requesting to bind service data flows described by the QoS rule to a dedicated QoS flow, and
wherein in case that the UE requests a new QoS rule, the precedence value is assigned not in the range from 70 to 99.
