    Abstract: It is disclosed a method and apparatus for controlling Idle-mode Signaling Reduction of a user equipment in a wireless communication system. Particularly, a method for controlling paging of a user equipment (UE) in which Idle-mode Signaling Reduction (ISR) is activated performed by a Serving Gateway (S-GW) in a wireless communication system may include transmitting a Downlink Data Notification (DDN) message to both of a first network node and a second network node, when receiving downlink data from a Packet Data Network Gateway (P-GW); and, when receiving a DDN Reject message from either one network node of the first network node and the second network node in response to the DDN message, transmitting a Stop Paging Indication message to a remaining network node.

    Abstract: Provided is a method for handling a packet data unit (PDU) session establishment procedure. The method may performed by an access and mobility management function (AMF) node and comprise: determining whether to reject a PDU session establishment request. The determination may be performed if the PDU session establishment request includes an existing PDU session identifier. Based on the existing PDU session identifier, an identifier of a session management function (SMF) node may be acquired. The PDU session establishment request may be accepted, if it is determined based the identifier of the SMF node that the SMF node and the AMF node belong to a same PLMN. The PDU session establishment request may be further accepted, if it is determined based the identifier of the SMF node that the SMF node belongs to a HPLMN. The PDU session establishment request may be rejected, if it is determined based the identifier of the SMF node that the SMF node and the AMF node do not belong to the same PLMN or the SMF node does not belong to the HPLMN.

    Abstract: A vehicle assistance apparatus includes an interface unit configured to receive information regarding an electric current provided to a brake lamp of a vehicle. The vehicle assistance apparatus also includes an object detection unit configured to detect an object outside the vehicle, and a processor. The processor is configured to determine, based on the detected object, a speed of the vehicle and also determine, based on the speed of the vehicle and the information regarding the electric current provided to the brake lamp of the vehicle, whether the vehicle undergoes acceleration during a braking operation of the vehicle. The processor is further configured to provide, based on a determination that the vehicle undergoes acceleration during the braking operation of the vehicle, a control signal to restrict further acceleration of the vehicle.

    Abstract: One embodiment of the present specification relates to a method by which a relay UE performs communication, comprising the steps of: receiving, from an access and mobility management function (AMF), a UE configuration update command message including information for requesting registration of the relay UE; transmitting, to a remote UE, a message indicating suspension of a PC5 connection; receiving, from the remote UE, a message indicating that the PC5 connection has been completely suspended; transmitting, to the AMF, a UE configuration update complete message in response to the UE configuration update command message; performing a registration procedure with the AMF; and resuming the PC5 connection with the remote UE.
