摘要
A method and system for data transmission, Donor evolved NodeB (DeNB), relay equipment and evolved packet core network node are disclosed by embodiments in the present invention. The data transmission method includes the steps of: receiving data transmitted to a DeNB via a bearer of a first equipment; mapping the data to a bearer of a second equipment according to a recorded mapping relationship between bearers of the first equipment and those of the second equipment, and transmitting the data via the bearer of the second equipment. When the first equipment is a relay equipment and the second equipment is a User Equipment (UE); or, the first equipment is a UE and the second equipment is a relay equipment, by using the embodiments in the present invention, the DeNB can transmit and receive data via bearers of the UE directly, and need not pass through the evolved packet core network node of the relay equipment, thereby under the Relay architecture, optimizing data transmission path of the UE, reducing router overhead and improving transmission efficiency.
