Abstract: An apparatus and method for providing an SFC service exposure function in a wireless communication system is proposed. The apparatus and method relates to a wireless communication system in general, and specifically, the method includes a process of requesting a service function chaining (SFC) service from a network exposure function (NEF), wherein, in the process of requesting the SFC service, the SFC service is requested by inputting an SFC policy identifier and a metadata value on a basis of an Nnef_TrafficInfluence service interface, and the SFC policy identifier is mapped to an identifier defined in a policy and charging control (PCC) rule.

Abstract: Provided are a method for performing port configuration of a 5G system (5GS) for providing a time synchronization service, and a network entity performing the same. A method for performing port configuration may include: when a grandmaster (GM) is determined to be a Time Sensitive Networking (TSN) GM outside the 5GS, performing, by a Network Exposure Function (NEF), port configuration of the 5GS in a Best Master Clock Algorithm (BMCA) scheme; and when the GM is determined to be a 5GS GM inside the 5GS, or the TSN GM outside the 5GS that does not support the BMCA, performing, by the NEF, port configuration of the 5GS in an external port configuration scheme.

Abstract: A traffic distribution method through a multi-access network in a network and a network entity performing the same. A first device belonging to the network may trigger a change to an ATSSS (access traffic steering, switching, and splitting) rule corresponding to an established multi-access PDU session (MA PDU session) when the MA PDU session is established. A session management function (SMF) may transmit a first message including the changed ATSSS rule to an access and mobility management function (AMF).
