Abstract: Provided are a method and device for efficient public land mobile network (PLMN) selection upon authentication failure for each network slice in a roaming network. A user equipment (UE) receives a registration rejection message from an access and mobility management function (AMF) of a first PLMN. The registration rejection message includes rejected network slice selection assistance information (NSSAI) including first single NSSAI (S-NSSAI) and cause value #62 for the rejected NSSAI. The UE: generates second requested NSSAI including second S-NSSAI on the basis that i) the UE does not have allowed NSSAI and configured NSSAI, and ii) default configured NSSAI includes the second S-NSSAI that is not included in the rejected NSSAI and corresponds to a network slice of which the UE requests registration; and transmits a second registration request message including the second requested NSSAI to the AMF of the first PLMN.

Abstract: One disclosure of the present specification provides a communication method, for handling a network error, performed by a terminal. The terminal can receive information relating to a second public land mobile network (PLMN) to which the terminal is subscribed from a base station in a first PLMN. The terminal can be connected to the first PLMN by means of the base station in the first PLMN on the basis of the information relating to the second PLMN. Information notifying of an error which has occurred in the second PLMN can be displayed on a display of the terminal.

Abstract: Disclosed are a method for selecting a session and a service continuity mode in a wireless communication system and a device therefor. Specifically, a method for selecting a session-and-service continuity (SSC) mode associated with a protocol data unit (PDU) session by a user equipment (UE) in a wireless communication system supporting a plurality of SSC modes may comprise the steps of: receiving a data transmission request from an application; checking whether a first PDU session can support an SSC mode associated with the application; and when the first PDU session can support the SSC mode associated with the application, transmitting data of the application to a network by using the first PDU session without sending a request for establishment of a new second PDU session to the network, although an SSC mode of the first PDU session does not match the SSC mode associated with the application.

Abstract: Disclosed in the present specification is a method by which a terminal acquires service function chain (SFC) information. The method comprises the steps of: transferring, to a controller, the terminal state information and/or the terminal configuration information; and receiving the SFC information, determined by the controller, by considering the terminal state information and/or the terminal configuration information, wherein the SFC information includes logical path information of a virtualized network function (VNF). The method can also include a step for receiving sub-chain information, determined by the controller, on the basis of the SFC information, or determining the sub-chain information on the basis of the SFC information.

Abstract: A disclosure of the present specification provides a method for managing uplink quality of service (QoS) by a base station. The method may comprise the steps of: determining whether a timer, driven by a terminal in relation to reflective QoS, has expired; during driving of the timer of the terminal, transmitting multiple packets within a traffic flow, to which the reflective QoS is applied, without setting at least one of a reflective QoS indication (RQI) and a QoS flow ID (QFI) for the multiple packets therewithin; and before expiration of the timer being driven by the terminal, setting at least one of the RQI and the QFI for at least one packet within the traffic flow and transmitting the set packet.

Abstract: The one disclosure of the present specification proposes a method for managing session. The method may be performed by a session management function, SMF, node and comprise: generating a packet data unit, PDU, session for a user equipment, UE; receiving, from an access and mobility management function, AMF, node, information about the UE; and determining, based on the information, whether to transmit an indication for notifying a user plane function, UPF, node to discard a downlink data for the PDU session of the UE. The determination may be dependent on whether the PDU session corresponds to a first service provided to the UE.

Abstract: 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.

Abstract: Disclosed herein are a method and apparatus for monitoring UE reachability in a wireless communication system. A method for monitoring UE reachability may include receiving, by a Mobility Management Entity, a monitoring request message for UE reachability including a maximum response time from a Home Subscriber Server, detecting, by the MME, the UE reachability if it is expected that paging is able to be transmitted to UE when extended Discontinuous Reception is applied to the UE, and sending, by the MME, a UE reachability notification to a Service Capability Exposure Function before a next paging occasion of the UE, wherein the maximum response time may indicate a time during which the UE maintains a reachable state so that downlink data is reliably delivered to the UE, and wherein an occasion when the UE reachability notification is transmitted may be determined by taking into consideration the maximum response time.
