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: A disclosed feature of the present specification provides a method for a source cell determining a handover of a packet data unit (PDU) session. The method may include a step of determining a target cell or target next generation radio access network (NG-RAN) based on a measurement report by a terminal. A handover region list can additionally be considered in the target cell or target NG-RAN determination step. The method may include a step of transmitting a handover request message that does not include context with respect to the PDU session to the target cell or target NG-RAN, based on the handover region list, if it is confirmed that the determined target cell or target NG-RAN cannot serve for the PDU session.

Abstract: Provided are a method, for configuring a bearer for transmission of user data in user plane-based cellular Internet of Things (CIoT) by a base station in a wireless communication system, and a device for supporting same. The base station can: receive a tracking area update (TAU) request message from a terminal; transmit to a mobility management entity (MME) a UE context resume request message comprising the TAU request message; receive from the MME a UE context resume failure message comprising a cause value; and determine whether or not a temporarily stopped UE context is to be remained on the basis of the cause value.
