Abstract: One embodiment of the present specification provides a method in which a terminal operates. The method comprises the steps of: transmitting a protocol data unit (PDU) session modification request message; and, in response to the transmitting of the PDU Session Modification Request message, receiving a PDU Session Modification command message, a PDU Session Modification ACK message, or a PDU Session Modification reject message, wherein the PDU Session Modification Request message includes a PDU session type to indicate industrial traffic, and wherein the PDU Session Modification reject message includes a cause value indicating that a network does not support the PDU session type.

Abstract: An intra prediction mode encoding and decoding method, an image decoding device, and an image encoding device operate by deriving most probable modes (MPMs) from surrounding prediction units adjacent to a current prediction unit and deriving an intra prediction mode of the current prediction unit on the basis of an MPM flag indicating whether an MPM having the same prediction mode as the intra prediction mode of the current prediction unit exists among the derived MPMs.
