    Abstract: A method for controlling mobile terminated (MT) data in a wireless communication system and a device therefor are disclosed. The method for controlling MT data by a user equipment (UE) in a wireless communication system includes receiving paging from a network and transmitting a tracking area update (TAU) request message to a mobility management entity (MME) in response to the paging when an EPS update status of the UE is EU2 NOT UPDATED due to an unsuccessful attempt of a last TAU procedure of the UE upon receiving the paging, wherein when the UE is using only signaling optimization to enable delivery of user data over a control plane via the MME, a first active flag in the TAU request message is set.

    Abstract: A method for transmitting or receiving a signal of a Session Management Function (SMF) in a wireless communication system comprises receiving a reject message for a message related to an activation command of a Protocol Data Unit (PDU) session, by the SMF, from a User Equipment (UE); requesting, to an AMF, an Access Management Function (AMF) information on a non-3GPP connection state modification of the UE by the SMF; receiving a message indicating that a non-3GPP connection state of the UE has been changed, by the SMF, from the AMF; and transmitting the message related to the activation command of the PDU session, which includes a new P-CSCF(Proxy-Call Session Control Function) list, by the SMF, to the UE, wherein the message indicating that the non-3GPP connection state of the UE has been changed indicates that a non-3GPP access of the UE has been changed from CM-IDLE to CM-connected.

    Abstract: One embodiment of the present invention relates to a method for performing location registration by a remote user equipment (UE) in a wireless communication system, the method comprising the steps of: transmitting a direct communication request message to a relay UE; receiving, from the relay UE, a direct communication response message including location registration period information and location registration performing time information, in response to the direct communication request message; and when the location registration performing time information expires, transmitting a first TAU request message to an MME, wherein the location registration period information is applied after the application of the location registration performing time information.
