摘要： Provided are a method and a device for processing a network slice-specific authentication and authorization (NSSAA) failure caused by a network error or timeout. An access and mobility management function (AMF): starts an NSSAA procedure for an NSSAA function (NSSAAF) and single network slice selection assistance information (S-NSSAI); and restarts the NSSAA procedure after waiting for a certain period, on the basis that the Hypertext Transfer protocol (HTTP) status code “504 Gateway Timeout” is received from the NSSAAF, and/or a response regarding the NSSAA procedure could not be received from the NSSAAF.

摘要： 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.

摘要： A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
