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.

Abstract: Embodiments of this patent application provide a data transmission method and an apparatus for determining, by a core network (CN) device, a length of a quality of service flow identifier (QFI) used when a protocol data unit (PDU) session is established or modified for a terminal device; and sending, by the CN device, a first message to a radio access network (RAN) device, where the first message includes length information of at least one QFI. After receiving the first message from the core network CN device, the access network RAN sends a second message to the terminal device, where the second message includes the length information of the at least one QFI.

Abstract: This application provides a quality of experience measurement method and apparatus. A terminal device reports, to a network side, quality of experience measurement configuration related information corresponding to a first user identity or a second user identity that has been configured or negotiated in advance, or specifies that application layer measurement corresponding to different user identities are independent of each other in an upper layer of an access stratum of the terminal device, or when application layer measurement corresponding to the first user identity is interrupted or terminated due to impact of a service corresponding to the second user identity, the terminal device reports the interruption or termination to the network side.
