Abstract: A method performed by a terminal operating in a wireless communication system. Based on that the terminal is located in a non-allowed area, and based on the terminal having a pending uplink signaling to inform a change in a Packet Switch (PS) data off status of the terminal, the terminal transmits a service request message to a network node. The service request message includes service type information that is related to the change in the PS data off status of the terminal. The terminal then receives, from the network node, a response message to the service request message.

Abstract: Provided are a method and a device for processing network slice selection assistance information (NSSAI) rejected due to a network slice-specific authentication and authorization (NSSAA) failure. A user equipment (UE) receives a UE configuration update command message from an access and mobility management function (AMF). On the basis of failure of NSSAA with respect to single NSSAI (S-NSSAI0, the UE configuration update command message includes time information related to a timer. The UE adds the S-NSSAI to a rejected NSSAI, starts the timer on the basis of the time information, and deletes the S-NSSAI included in the rejected NSSAI after the timer expires.

Abstract: One disclosure of the present specification provides a method in which a UE performs communication related to PS Data Off. The method may comprise: a step for transmitting a first PDU session establishment request message in order to establish a PDU session associated with non-3GPP access or 3GPP access; and a step for transmitting a second PDU session establishment request message in order to perform a handover between the non-3GPP access and the 3GPP access for the PDU.

Abstract: 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.

Abstract: 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.

Abstract: Data can be transmitted to a control plane rather than to a user plane. When a DL response to UL data transmitted in a non-access stratum (NAS) message is expected, user equipment (UE), an eNB and a mobility management entity (MME) do not immediately perform an S1 release procedure because a cause of the S1 release occurs, but proceed with a part of the S1 release procedure after a predetermined time.

Abstract: In a wireless communication system of the present disclosure, when activation of a protocol data unit (PDU) session of a user equipment (UE) is needed, the UE performs an access control check to determine whether an access attempt for the PDU session is allowed. If the access attempt is allowed, the UE transmits a service request for the PDU session. The access control check for the PDU session is performed even if the UE is in a connected state.

Abstract: According to an aspect of the present invention, a method for transporting a non-access stratum (NAS) message of an access and mobility management function (AMF) in a wireless communication system may include: receiving, from a user equipment (UE), an uplink (UL) NAS message including a session management (SM) message for a request related to a protocol data unit (PDU) session; transporting, to a predetermined second Session Management Function (SMF), the SM message if it is determined that it is impossible to route the SM message to a first SMF as a transport target of the SM message; receiving, from the second SMF, an SM rejection message for the SM message; and transmitting, to the UE, a downlink (DL) NAS message including the SM rejection message.

Abstract: A method for a user equipment (UE) connecting to a network includes: if second connection is to be executed by means of a second access, determining whether or not first connection has been previously executed by means of a first access; and, if the first connection by means of the first access has been executed and the second connection by means of the second access is determined to be an addition, transmitting a connection request message comprising identification information of a control plane (CP) function node. The identification information of the control plane (CP) function node could have been obtained during the first connection by means of the first access. Both the first connection by means of the first access and the second connection by means of the second access can be managed by means of the control plane (CP) function node.

Abstract: A network may instruct to change the connection of a user equipment connected to the network in a first mode, to a second mode. The network may instruct re-establishment while instructing the user equipment to change the connection. In this case, the network and the user equipment release the connection of the first mode while maintaining an uplink resource allocated to the user equipment. After completing the connection release, the user equipment may transmit a connection request to the network using the uplink resource directly without any access process.
