Abstract: A non-access stratum based access method and a terminal supporting the same. The terminal receives an Internet protocol (IP) address allocated from a first gateway included in a non-3rd generation partnership project (3GPP) access network. In addition, the terminal applies a non-access stratum (NAS) protocol to a first device managing mobility of the terminal through the IP address.

Abstract: Proposed is an apparatus and method for requesting time-sensitive communication (TSC) management information, wherein the method for directly sending TSC management information in wireless communication systems may include a process of sending TSC management information from TSN AF (time-sensitive network application function) to PCF (policy control function), where TSC management information is composed of at least one of PMIC, a port number, and UMIC, and an address information of a target NF, a process of PCF sending the changed policy information to SMF when there is a change in policy information, where the changed policy information is composed of TSC management information, and a process of requesting TSC management information to be included when the SMF requests PFCP session report from UPF.

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 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: 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: 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 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).
