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).

Abstract: An apparatus and method for directly exposing, by user plane function/network side-time sensitive networking translator (UPF/NW-TT), event result information to time sensitive networking (TSN) or time sensitive communication time synchronization function (TSCTSF) through service interface (Nupf) in wireless communication system. A method of operating event processing for TSN or TSC includes: when policy control function (PCF) performs TSC event subscription, receiving TSC management and control information for direct reporting notification of event result from TSN-application function or TSCTSF and transmitting the TSC management and control information to session management function (SMF); regenerating the TSC management and control information and transmitting the regenerated TSC management and control information to UPF/NW-TT through N4 interface; and receiving the TSC management and control information from SMF, and when a corresponding event occurs, transmitting the TSC management information including the event result to a target in the control information through SBI.

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.

Abstract: A steering rule provision method for traffic distribution in a network and a network entity performing the same network. A session management function (SMF) may transmit a first message including a multi-access rule (MAR) to a user plane function (UPF), when establishing or modifying a packet data unit (PDU) session for ATSSS (Access Traffic Steering, Switching, and Splitting). The SMF may receive a second message that is a response message to the first message from the UPF.

Abstract: A method for releasing a context of a user equipment in a non-3GPP access network and a network entity performing the same are disclosed. In a case in which the UE is a unreachable state, a non-3GPP interworking function (N3IWF) may a UE context release request message to an access and mobility management function (AMF), and may perform protocol data unit (PDU) session user plane de-activation between the AMF, a session management function (SMF), and a user plane function (UPF). In addition, the AMF may transmit a UE context release command message to the N3IWF, and the N3IWF may transmit a UE context release complete message to the AMF.
