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: A method for transmitting, by user equipment, a PDU session establishment request includes: receiving a session management message based on an SSC mode from an SMF through an AMF in a state in which a back-off timer associated with a DNN-based congestion control is in operation, wherein the session management message is associated with a DNN to which the DNN based congestion control is applied; and transmitting a PDU session establishment request to the AMF for establishment of a new PDU session associated with the DNN on the basis of the session management message. The PDU session establishment request includes information for preventing rejection of the PDU session establishment request, and the information for preventing the rejection may be used to make the AMF ignore the DNN-based congestion control and transmit the PDU session establishment request to the SMF associated with the new PDU session.

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: A method for transmitting and receiving a signal related to switching 3rd generation partnership project (3GPP) access to a 5th generation system (5GS) in an evolved packet system (EPS) in a wireless communication system includes: a step in which a second access and mobility management function (AMF) receives a message, related to a registration request and including a first 5G globally unique temporary identifier (5G-GUTI), from a UE that receives non-3GPP access service through the 5GS and 3GPP access service through the EPS; and a step in which the second AMF transmits to the UE, a message related to a registration acceptance and including a second 5G-GUTI. The first 5G-GUTI includes ID information on the first AMF which serves the non-3GPP access of the UE, and the second 5G-GUTI includes ID information on the second AMF which serves both the non-3GPP access and the 3GPP access of the UE.

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.
