<p>Embodiments of the present invention provide a data transmission method, a base station, an access network device, and a user equipment. The method includes: in a case of determining that heterogeneous network aggregation is to be enabled, establishing, by a base station of a first communications network, a first interface to an access network device of a second communications network, and notifying the access network device and a UE to establish a second RB between the access network device and the UE; and exchanging, by the base station through the first interface, data corresponding to the second RB with the access network device after the second RB is established, and perform aggregation or splitting on the data corresponding to the second RB and data corresponding to a first RB between the base station and the UE; where the data that corresponds to the second RB and is exchanged by the base station with the access network device through the first interface is PDCP PDUs. According to the embodiments of the present invention, a utilization rate of network resources and a peak rate of the UE can be improved.</p> |
