FIELD: communication.
SUBSTANCE: invention relates to communication means. By means of the central unit-user plane node (CU-UP), a first information transmitted by the central unit-control plane node (CU-CP) is received, wherein the first information indicates the CU-UP to display a first data packet to the data radio bearer (DRB), wherein the first information additionally indicates the CU-UP to set the field for indicating the reflective display of the first data packet, wherein the first data packet belong to the quality of service (QoS) stream. The field for indicating the reflective display therein indicates the terminal apparatus to display the uplink data packet in the QoS stream on the DRB, wherein the field for indicating the reflective display comprises one bit. By means of the CU-UP, a first data packet transmitted by the main network apparatus is received. By means of the CU-UP, the field for indicating the reflective display of the first data packet is set in 1, which indicates the terminal apparatus to save the display rule from the QoS stream to the DRB. By means of the CU-UP, the first data packet is transmitted to the terminal apparatus on the DRB.
EFFECT: increase in the stability of the network.
