Abstract:
Embodiments of the present disclosure relate to the field of communications technologies, and disclose a data stream transmission method, and a related device and system. The data stream transmission method includes: a user equipment establishes a first network link over a first network and a second network link over a second network with a network side, where the first network is different from the second network; the user equipment associates the first network link with the second network link; and the user equipment distributes, according a scheduling algorithm, a data stream to the first network link and to the second network link for transmission. In the embodiments of the present disclosure, hybrid transmission of a data stream may be implemented in different networks. Compared with an existing solution, in the embodiments of the present disclosure, distribution may be performed more flexibly, and a quality of service assurance may be improved.
