摘要： A user equipment according to the present invention performs a handover from a first system to a second system. When a user equipment receives a command to hand over to the second system, while using a plurality of protocol data unit (PDU) sessions for the same data network (DN) in the first system, the user equipment transmits first session information of a first PDU session among the plurality of PDU sessions, establishes a packet data network (PDN) connection with the second system, on the basis of the first session information, and maps the first PDU session to the PDN connection. When the user equipment is required to establish a dedicated bearer for a PDU session (second PDU session) other than the first PDU session among the plurality of PDU sessions, the user equipment transmits a bearer generation request message requesting to generate a dedicated bearer for the PDN connection.

摘要： Disclosed in the present specification is a method by which a user equipment (UE) performs access control. The method comprises the steps of: allowing a non-access-stratum (NAS) layer of the UE to transfer information on an important service and a NAS signaling request to a radio resource control (RRC) layer, when the important service is required even if access to a cell is currently interrupted or a back-off timer is operated; and allowing the RRC layer to skip or override an inspection for access control on the basis of the information on the important service, wherein, the information on the important service can be set in advance.

摘要： Provided is a method for a wireless device for transmitting an RRC message according to one disclosure of the present specification. The method may comprise a step for an NAS stratum of the wireless device transmitting an NAS signaling request message to an AS layer to transmit the former to a network node. The NAS signaling request message can comprise therein an indication of one or both preferred or required plans from among the plans for optimizing the EPS for CIoT using a control plane (CP) or a user plane (UP). The method may comprise a step for the NAS stratum of the wireless device receiving, from the AS stratum, an NAS signaling acceptance message or NAS signaling rejection message from the network node.
