Abstract
A data transmission method, an access network device, and a communications system are provided. The access network device obtains, from a first core network (CN) element through a control plane interface, information about a bearer that needs to be established, establishes the bearer according to the information about the bearer, and notifies, through the first CN element, the established bearer to a second CN element for use. When a signal of the control plane interface is interrupted, the access network device transmits to-be-transmitted data in an existing service of UE by using the established bearer.
