Abstract: Disclosed herein are a method for tracking area update in a wireless communication system and an apparatus therefor. Specifically, a method for user equipment (UE) to perform a tracking area update (TAU) procedure in a wireless communication system comprises: a step of transmitting a TAU request message to a mobility management entity (MME); and a step of receiving a TAU accept message from the MME, wherein if the UE uses signaling optimization to enable the delivery of user data through a control plane over the MME, and the UE does not have pending user data to be transmitted through a user plane and has pending user data to be transmitted through the control plane over the MME, then a first active flag can be set in the TAU request message.

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: Disclosed are a method for resuming a connection in a wireless communication system and a device for same. More particularly, a method for executing a procedure of resuming a connection by a network node in a wireless communication system can comprise the steps of: receiving a message, which comprises a tracking area update request (TAU request) of a user equipment (UE), from an eNodeB (eNB), wherein the message comprises a result that determines the validity with regard to whether or not resumption of a connection of the UE is possible by means of the eNB; determining whether or not an E-UTRAN radio access bearer (E-RAB) setup for the UE is required; and determining a message to be transmitted to the eNB on the basis of whether or not the E-RAB setup for the UE is required and/or whether or not resumption of a connection of the UE is possible.

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: One disclosure of the present specification provides a method for a proxy-call session control function (P-CSCF) of a home public land mobile network (H-PLMN) to register a roaming user equipment with an IP multimedia subsystem (IMS) network. The method may comprise the steps of: receiving an identifier of a visited public land mobile network (V-PLMN) in which a user equipment is roaming, wherein the identifier of the V-PLMN is received in a state where packet data network (PDN) connection for the user equipment is established but the user equipment is not registered with the IMS network; receiving, from the user equipment, a REGISTER message for registration with the IMS network; adding the identifier of the V-PLMN to a header of the REGISTER message; and transmitting the REGISTER message to which the identifier of the V-PLMN is added to an Interrogating-CSCF (I-CSCF).

Abstract: Disclosed are a method for controlling a congestion in a wireless communication system and a device for same. More particularly, a method for executing a congestion control by a network node in a wireless communication system can comprise the steps of: detecting the congestion of one or more dedicated core networks (DCN) served by the network node; receiving a non-access stratum (NAS) request message from user equipment (UE); obtaining subscription information, which includes a UE usage type of the UE, from a home subscriber server (HSS); selecting a DCN for serving the UE based on the UE usage type; and, when the DCN for serving the UE is a DCN of which the congestion has been detected, transmitting to the UE a NAS reject message, which includes a backoff timer of the selected DCN, as a response to the NAS request message.

Abstract: User data may be transmitted through a signaling radio bearer (SRB) by using an NAS message. A new SRB different from the existing SRB0, SRB1, and SRB2 may be defined for transmission of the user data. The new SRB may be used to deliver the NAS message containing the user data before security is activated.
