Abstract
A data transmission method, an apparatus, and a system. The method includes: a source network device performs cascading processing on at least two data units to obtain a first data packet, where data included in the at least two data units belongs to a same radio bearer or quality of service flow of a terminal device, and the first data packet is a packet data convergence protocol (PDCP) layer data packet or a service data adaptation protocol (SDAP) layer data packet; and sends the first data packet to a target network device through a first tunnel. According to the foregoing method, a plurality of data units is cascaded to obtain one data packet, so that header overheads of the cascaded data packet can be reduced, lossless handover under a cascading function can be implemented, and a cascading gain can be obtained.
