Abstract: Proposed is a wireless communication system and, more particularly, an apparatus and method for providing a N6-LAN service using SFC in a wireless communication system. A method of supporting an N6-LAN traffic steering function using an SFC technology in a wireless communication system, includes a process in which a policy control function (PCF) configures additional information for N6-LAN traffic steering on the basis of a policy and charging control (PCC) rule, a process of transmitting the configured additional information to a session management function (SMF), a process in which the SMF configures a forwarding action rule (FAR) including the additional information for N6-LAN traffic steering, a process in which the SMF transmits the FAR including the additional information to a user plane function (UPF), and a process in which the UPF performs SFC encapsulation on the basis of a predefined SFC policy and the FAR.
