1. A method performed by a user plane function (UPF) node in a wireless communication system, comprising:
receiving, from a session management function (SMF) node, a message including information on a rule, wherein the information on the rule includes a packet detection rule (PDR), and a forwarding action rule (FAR);
receiving, from an entity associated with the UPF node, at least one packet comprising user traffic;
detecting the at least one packet comprising user traffic based on the PDR which includes information for matching the at least one packet with a flow; and
when the PDR does not include information for matching the at least one packet with the flow, transmitting, to an another UPF node, the at least one detected packet, wherein the another UPF node is selected based on the FAR.
