Abstract: Provided is a method and device for an N14 interface support indicator for service continuity. A next generation radio access network (NG-RAN) node of a first network receives an initial UE context configuration request message from an access and mobility management function (AMF) of the first network. The initial UE context configuration request message includes (i) a registration acceptance message that is a response to a registration request message, and (ii) information on at least one second network supported by the first network, and the registration acceptance message includes information on whether an N14 interface between the AMF of the first network and an AMF of the at least one second network is supported. The NG-RAN node of the first network initiates handover to one network among the at least one second network, based on the information on the at least one second network.

Abstract: A method and apparatus for supporting a DAPS handover procedure in a wireless communication system is provided. A target BS receives, from a source BS, a first message for a dual active protocol stack (DAPS) handover of a wireless device. A target BS transmits, to the source BS, a second message to inform that the DAPS handover is accepted. A target BS receives, from the wireless device, a third message including an information that the wireless device does not perform the DAPS handover. A target BS transmits, to the source BS, a fourth message including the information received from the wireless device.

Abstract: A method and apparatus for controlling mobile early data transmission (EDT) procedure in a wireless communication system is provided. A first core network node, in a wireless communication, receives, from a second core network node, a message for a downlink Data including a size of the downlink data. The first core network node determines whether to initiate an early data transmission (EDT) procedure for the downlink data based on the size of the downlink data. The first core network node transmits, to a radio access network (RAN) node, a paging message including information related to the EDT procedure for the downlink data based on the decision to initiate the EDT procedure for a wireless device.

Abstract: Provided are a method of managing UE context and a device supporting the method. According to one embodiment of the present invention, a method for managing UE context in a wireless communication system includes: receiving a UE context request message including a radio resource control (RRC) establishment cause from a second BS, wherein the first BS and the second BS are located in a same radio access network (RAN)-based notification area (RNA); and when the RRC establishment cause is related to RNA update, transmitting a UE context response message to the second BS, wherein the UE context response message piggybacks a RRC message requesting a UE to move to a RRC inactive state.

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.
