Japanese Patent JP7177259

B2

This application provides a data transmission method and an apparatus, to implement quality of service QoS flow-based data transmission in an architecture in which a CU-CP and a CU-UP are separated from each other. In embodiments of this application, in a scenario in which the CU-CP and the CU-UP are separated from each other, when receiving data of a quality of service QoS flow, the CU-UP may send a QoS flow identity ID and a PDU session ID that are of the data of the QoS flow to the CU-CP, and a PDU session corresponding to the PDU session ID includes the data of the QoS flow. In this way, the CU-CP can determine a manner of mapping the data of the QoS flow to a radio bearer, so that a transmission performance parameter of the QoS flow is met, and user experience is improved.
