Abstract: A traffic distribution method through a multi-access network in a network and a network entity performing the same are disclosed. An access and mobility management function (AMF) may receive a PDU session modification request message including an ATSSS (access traffic steering, switching, and splitting) preference, which is a preference for an ATSSS rule, from an user equipment (UE) when a multi-access PDU session (MA PDU session) is established and the UE desires to change the ATSSS rule corresponding to the established MA PDU session. The AMF may transmit a first message including the ATSSS preference to a session management function (SMF).

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: Provided is a method of jitter monitoring for time sensitive communication (TSC) in a wireless communication network. The method of jitter monitoring may include: receiving, by a user plane function (UPF), a delay and jitter measurement request from an application function (AF); measuring, by the UPF, a delay and a jitter in response to the delay and jitter measurement request; and transmitting, by the UPF, the measured delay and jitter to the AF.

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.

Abstract: Provided is a method of creating a QoS flow for a time synchronization protocol in a wireless communication network. A method of creating a QoS flow for a time synchronization protocol in a wireless communication network includes: receiving, by a Session Management Function (SMF), the PTP profile information from the UE, together with at least one of a DNN, a S-NSSAI information and a session ID for a Time Sensitive Communication (TSC) service; setting, by the SMF, a PCCrule of the QoS flow for the time synchronization protocol; providing, by the SMF, the QoS flow and a SDF filter information for the QoS flow to a User Plane Function (UPF); and providing, by the SMF, the QoS flow and a QoS rule filter to an Access and Mobility Management Function (AMF).

Abstract: The present disclosure relates generally to a wireless communication system. More particularly, the present disclosure relates to an apparatus and a method for applying a service-based interface for user traffic processing in a wireless communication system. An operation method of a user plane function (UPF) in a wireless communication system includes: transmitting information on the UPF to a network repository function (NRF) to register a service of the UPF in the NRF, wherein the information on the UPF includes a universally unique identifier (UUID), and information on the service provided by the UPF; and receiving the information on the registered service of the UPF from the NRF.
