Abstract: User equipment may send a channel allocation request (hereinafter referred to as a first channel allocation request) to a network for transmission of data. When the transmission of data has backed off, the user equipment may send a channel allocation request (hereinafter referred to as a second channel allocation request) again for the transmission of data. At this time, the second channel allocation request may be transmitted to the network together with a priority raise request if a remaining timeframe Tremain of an upper timeframe T is smaller than a certain guard time.

Abstract: When the amount of downlink (DL) data for a user equipment (UE), buffered by a network, exceeds a predetermined reference value, the network establishes a user plane connection with the UE by changing a connection mode with the UE. Even when a control plane connection that can be used for user data transmission exists and access to the UE is possible, the network does not transmit the DL data to the UE on the control plane connection, but transfers the DL data to the UE after the user plane connection is established.

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: Disclosed are a method for cell granularity reporting in a wireless communication system and a device therefor. The method for performing cell granularity reporting by a user equipment (UE) in an idle state in a wireless communication system includes receiving a cell granularity reporting configuration from a network, detecting whether a cell in which the UE is camping in the idle state is changed, and when it is detected that the cell in which the UE is camping is changed, transmitting cell change information to the network, wherein the cell granularity reporting configuration includes an indication regarding whether to receive a multimedia broadcast and multicast service (MBMS), and when the indication regarding whether an MBMS is received is activated, the UE does not perform the cell granularity reporting unless the UE receives MBMS data.
