Abstract: One disclosure of the present specification provides a method for a terminal creating a session, the terminal supporting next-generation mobile communication. The method may comprise the steps of: determining that a session must be newly created if the creation of a session is not included in a process of attaching to a core network of a next-generation mobile communication; on the basis of service type information, determining that the session being newly created needs to be always-on, or in other words, always-connected; and transmitting, to a control plane (CP) function node for managing the session, a connectivity request message including information indicating that the session that needs to be always-on, or in other words, always-connected, has been requested.

Abstract: In an aspect of the present invention, a method for a user equipment to update a policy in a wireless communication system may include transmitting a first registration request message to an access and mobility management function (AMF), wherein the first registration request message includes requested network slice selection assistance information (NSSAI) including single (S)-NSSAI corresponding to a network slice with which the user equipment wants to register; receiving a first registration accept message as a response to the first registration request message from the AMF, wherein the first registration accept message includes an allowed NSSAI including at least one S-NSSAI allowed by the AMF; and requesting the update of a network slice selection policy (NSSP) associated with new S-NSSAI from the AMF when the new S-NSSAI not included in the requested NSSAI is included in the allowed NSSAI and the NSSP associated with the new S-NSSAI is not present.

Abstract: Disclosed are a method for processing a loss of access wherein a first network entity of a first network determines, from a measurement report of a terminal operating by SCM or TSCM, a loss of access of the terminal to the first network, and notifies a second network entity of the loss of access, and a method for processing a loss of access wherein, when the loss of access of the terminal is received, the second network entity processes the loss of access according to whether a condition for dropping a loss of access is satisfied.

Abstract: A first network device receives a request associated with data notification for a user equipment (UE). When the UE is in a mode in which communication of mobile terminated data is restricted and the first network device detects that the UE is in a non-allowed area, the first network device rejects the request unless the data notification is for a regulatory prioritized service.

Abstract: An embodiment of the present specification provides a method for acquiring an identifier of a visited public land mobile network (V-PLMN), in which a user equipment is roaming, by a proxy-call session control function (P-CSCF) of a home public land mobile network (H-PLMN). The method may comprise the steps of: receiving a register message from the user equipment; generating a first V-PLMN identifier on the basis of the register message; and transferring the first V-PLMN identifier to a home subscriber server (HSS), wherein whether the first V-PLMN identifier corresponds to an identifier of the V-PLMN which is serving the user equipment is verified by the HSS through comparison with a second V-PLMN identifier acquired in an initial attach procedure for an evolved packet core (EPC) of the user equipment.

Abstract: One disclosure of the present invention provides a method for selecting an enhanced packet data gateway (ePDG). The method may be performed by a user equipment (UE) and comprise: determining, by the UE which has roamed from a home public land mobile network (H-PLMN) to a visited public land mobile network (V-PLMN), whether there exists an indication for selecting ePDG in the V-PLMN; determining, by the UE, whether the UE has attached to any PLMN in the V-PLMN, when it is determined that there exists the indication; determining, by the UE, whether there exists an ePDG PLMN list for the any PLMN in the V-PLMN, when it is determined that the UE has attached to the any PLMN; and selecting, by the UE, at least one ePDG in the ePDG PLMN list.
