摘要： According to one aspect of the present invention, a method for supporting a user equipment (UE) handover of a target (T)-access and mobility management function (AMF) in a wireless communication system may comprise the steps of: receiving a UE context creation request message from a source (S)-AMF, wherein the UE context creation request message includes packet data unit (PDU) session identifiers (ID) as a handover target and single (S)-network slice selection assistance information (NSSAI) corresponding to each PDU session ID; determining whether the corresponding S-NSSAI is valid in the T-AMF; and sending, to a session management function (SMF), a PDU session update session management (SM) context request message only for a PDU session ID that corresponds to the S-NSSAI determined to be valid according to the determination result, out of the PDU session IDs.

摘要： It is disclosed a method for managing a PDU session in a wireless communication system and an apparatus for supporting the same. Particularly, a method for performing handover of a User Equipment (UE) performed by a source Radio Access Network (RAN) that includes a processor, a memory and a communication module in a wireless communication system may include determining to initiate handover to a target RAN; and transmitting a Handover Required message to a source Access and Mobility Management Function (AMF), and the handover is a handover in a case that there is no interface between the RANs or AMF change is required, and the Handover Required message includes a PDU session Identifier (ID) of an activated Protocol Data Unit (PDU) session.

摘要： An embodiment of the present invention relates to a method for an access and mobility management function (AMF) transmitting and receiving a signal related to a handover from 5GS to an evolved packet system (EPS) of a user equipment (UE) in a wireless communication system the method comprising a step in which the AMF receives a handover required message from a next-generation radio access network (NG-RAN); a step in which the AMF requests a session management (SM) context to a packet data network gateway+session management function (PGW+SMF); a step of receiving an SM context from the PGW+SMF; and a step in which the AMF transmits a handover command to the NG-RAN, wherein the SM context request is for a PDU session associated with 3GPP access among a plurality of protocol data unit (PDU) sessions.

摘要： Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method can comprise the steps of: transmitting a protocol data unit (PDU) session establishment or modification request message; and receiving a PDU session establishment or modification rejection message. The rejection message can comprise information on a backoff timer and session network slice selection assistance information (S-NSSAI). The method can comprise the steps of: driving the backoff timer while being linked with the S-NSSAI; and performing access control on the basis of the S-NSSAI.

摘要： Systems and techniques for handling a protocol data unit (PDU) session by a wireless device implementing an access stratum (AS) layer and a non-access stratum (NAS) layer in a wireless communication system. An example technique includes determining, by the AS layer of the wireless device, whether a user plane for the PDU session is activated or released; transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is activated, first information indicating that the user plane for the PDU session is activated; and transferring, by the AS layer and to the NAS layer of the wireless device based on a determination that the user plane for the PDU session is released, second information indicating that the user plane for the PDU session is released.

摘要： A disclosure of the present specification provides a method performed by a network node that manages mobility in a first public land mobile network (PLMN). The network node may receive an access request message of a terminal from a base station in the first PLMN. The terminal may be a terminal having joined a second PLMN. On the basis of occurrence of a failure in the second PLMN, the network node may determine whether to allow the terminal to roam to the first PLMN.
