Abstract: In one embodiment of the present invention, a method for enabling a UDM (Unified Data Management) to perform a registration related procedure of an AMF (Access and Mobility Management Function) in a wireless communication system comprises the steps of: receiving, by the UDM, a message related to serving AMF registration of a UE, which includes access type information and ID (Identity) information, from a first AMF; transmitting, by the UDM, a deregistration related message to a second AMF when the second AMF exists, wherein the second AMF is registered as a serving AMF of the UE and related to the access type information.

Abstract: An embodiment of the present invention provides a method for supporting non-access stratum (NAS) signaling of a user equipment (UE) by a base station in a wireless communication system, the method comprising the steps of: transmitting, to the UE, information for supporting a connection to a next generation (NG) core; receiving a NAS-related message from the UE; performing one of MME selection and AMF selection according to whether the NAS-related message includes information regarding the use of NAS; and transmitting an NAS message to an MMF or an AMF which is determined as a result of performing one of the MME selection and the AMF selection.

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.

Abstract: When a non-access stratum (NAS) message is generated in an NAS layer of a user equipment, the NAS layer transfers the NAS message and type information to an access stratum (AS) layer of the user equipment. An AS message containing the NAS message is transmitted to a network. The type information indicates whether the NAS message is a first type message containing user data or a second type message without user data.

Abstract: An embodiment of the present invention provides a method for transmitting/receiving a location registration-related message by a user equipment (UE) in a wireless communication system, the method comprising the steps of: switching to an idle mode by the UE; transmitting, by the UE, a registration request message including location registration-related information to a AMF (core access and mobility management function) through a RAN (radio access network); and receiving, by the UE, a registration accept message as a response to the registration request message from the AMF through the RAN, wherein the registration request message includes information related to a first PDU (protocol data unit) session for activation.

Abstract: When a specific case occurs, user equipment can initiate a tracking area update (TAU) step by transmitting a TAU request. If the user equipment is using a control plane connection for the transport of user data when a radio resource control (RRC) connection failure occurs and there is no pending signaling or uplink user data, the specific case can be applied to a case in which it is indicated, to a network, that downlink data reception subsequent to the uplink data transmission is predicted.
