Abstract  Abstract

Embodiments of the present application provide a data transmission method, a transmitting end device, and a receiving end device, which improve the reliability of data transmission during switch of a Quality of Service flow (QoSflow) between multiple data radio bearers (DRBs). The method comprises: a transmitting end device switches a DRB corresponding to a first QoSflow from a first DRB to a second DRB; the transmitting end device sends an unsent data packet in the first QoSflow to the receiving end device by means of the second DRB.
