Abstract: The present disclosure relates to data transmission methods and apparatus to implement quality of service (QoS) flow-based data transmission in an architecture in which a central unit-control plane (CU-CP) and a central unit-user plane (CU-UP) are separated from each other. In one example method, when receiving data of a QoS flow, the CU-UP may send a QoS flow identity (ID) and a protocol data unit (PDU) session ID that are of the data of the QoS flow to the CU-CP, where a PDU session corresponding to the PDU session ID includes the data of the QoS flow.

Abstract: The present disclosure relates to delay measurement methods and apparatus. In one example method, a first communications device receives a data unit from a second communications device, where the data unit includes time information, the time information is used to indicate a first moment at which the second communications device sends the data unit, and the time information indicates the first moment based on a part of bits of a frame number. The first communications device determines a delay from the second communications device to the first communications device based on the first moment and a second moment, where the second moment is a moment at which the first communications device receives the data unit.
