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: One disclosure of the present specification provides a method for operating in relay user equipment (UE). The method may comprise the steps of: receiving a communication request message directly from a first remote UE; performing a procedure for establishing an access and mobility management function (AMF) entity and a protocol data unit (PDU) session; and storing mapping information between an identifier of a PC5 link with the first remote UE and an identifier of the PDU session on the basis of the PDU session being established for an unstructured PDU session type for unstructured traffic.

Abstract: One disclosure of the present specification provides a method in which a user equipment (UE) performs an attach request procedure. The method comprises a step of transmitting an attach request message to a second system when an intersystem change from a first system to the second system is required in a state where a back-off timer associated with a data network name (DNN) based congestion control is running. The attach request message may include information on a packet data unit (PDU) session used by the UE in the first system. The information on the PDU session may be used so as not for the attach request message to be rejected by a second network, even if the back-off timer associated with the DNN-based congestion control is running.

Abstract: A user equipment according to the present invention performs a handover from a first system to a second system. When a user equipment receives a command to hand over to the second system, while using a plurality of protocol data unit (PDU) sessions for the same data network (DN) in the first system, the user equipment transmits first session information of a first PDU session among the plurality of PDU sessions, establishes a packet data network (PDN) connection with the second system, on the basis of the first session information, and maps the first PDU session to the PDN connection. When the user equipment is required to establish a dedicated bearer for a PDU session (second PDU session) other than the first PDU session among the plurality of PDU sessions, the user equipment transmits a bearer generation request message requesting to generate a dedicated bearer for the PDN connection.

Abstract: Provided in one disclosure of the present specification is a method by which a session management function (SMF) node manages a session. The method can comprise the steps of: transmitting, to an access and mobility management function (AMF) node, a registration request for notifying of state information of user equipment (UE) capable of accessing a local area data network (LADN) through any one of a first access network and a second access network; receiving, from the AMF node, changed state information when the state information of the UE is changed; and determining whether to release or deactivate a PDU session of the UE on the basis of the received information.

Abstract: Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method comprises the steps of: allowing a non-access-stratum (NAS) layer of the UE to transfer information on an important service and a NAS signaling request to a radio resource control (RRC) layer, when the important service is required even if access to a cell is currently interrupted or a back-off timer is operated; and allowing the RRC layer to skip or override an inspection for access control on the basis of the information on the important service, wherein, the information on the important service can be set in advance.

Abstract: One disclosure of the present specification provides a method for supporting service continuity after a terminal performs a handover. The method may comprise: a step of transmitting, when re-assigned from a source user plane (UP) functional node to a target UP functional node in accordance with performing a handover to a target base station, a PDU session creation request message to create a new PDU session with the target UP functional node; a step of receiving a PDU session creation response message including a newly allocated second IP address; a step of transmitting a tunneling request message including information on the newly allocated second IP address and information on a service flow requiring service continuity; and a step of encapsulating a packet, which has been generated with an existing first IP address by an upper layer of the terminal, with a new second IP address by a lower layer of the terminal and transmitting the encapsulated packet to the tunneling entity.

Abstract: Provided in one disclosure of the present specification is a method selecting a network and routing traffic by a user equipment (UE). The method may comprise a step of receiving, from a base station, radio access network (RAN) support information, wherein the RAN support information may include RAN support parameters and a timer value. The method comprises the steps of: receiving, from an upper layer, an evaluation request; evaluating the RAN support parameters according to the request from the upper layer; delivering, to the upper layer, an indication which indicates a detour to wireless local area network (WLAN) access and a detour to 3GPP access according to the result of the evaluation, and/or an indication which indicates maintaining current access; and performing feedback to the step of evaluating when the timer expires.
