Base station networking method and system

The invention provides a base station networking method and system. A base station comprises a macro base station and a small base station; and the method comprises the following steps: the small base station encapsulates Ethernet data messages from the small base station according to an IR transmission frame format; the macro base station de-encapsulates the encapsulated Ethernet data messages from the small base station into Ethernet network messages, and transmits the Ethernet network messages to an evolved packet core network connected with the macro base station. By using the networking method provided by the invention, the capacity of the signal coverage region corresponding to the small base station can be improved from maximum 20M bandwidth*2 antennas*2 carrier waves to maximum 20M bandwidth*2 antennas*5 carrier waves. Under the situation of not upgrading the self-contained hardware of the small base station, the improvement of the performance and the capacity of the cell covered by the small base sta
