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: 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 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: A method for managing registration in a wireless communication system and a device for the same are disclosed. More specifically, the method for managing registration performed by a User Equipment (UE), that cannot be paged by a network and does not perform a periodic registration area update, in the wireless communication system, may include receiving a timer value for managing a Deregistered state of the UE from the network during a registration procedure, starting a timer if the UE enters an Idle state, and allowing the UE to enter the Deregistered state if the timer expires.
