Abstract
This application provides a transmission method and a data transmission apparatus, so as to avoid out-of-order of data packets. The method includes: sending, by a source access network device, a first proportion of data packets in a first Packet Data Convergence Protocol PDCP entity in the source access network device to a target access network device by using a data tunnel between the source access network device and a second PDCP entity of the target access network device, where the first proportion of data packets are data packets of a first quality of service QoS flow in a first protocol data unit PDU session, the first PDU session includes at least one QoS flow, the at least one QoS flow corresponds to at least one PDCP entity, the at least one QoS flow includes the first QoS flow, the at least one PDCP entity includes the first PDCP entity, and the first PDCP entity corresponds to the first QoS flow; and sending, by the source access network device, first indication information to the target access network device, where the first indication information is used to indicate that all the first proportion of data packets in the first PDCP entity have been sent.
