METHOD, SYSTEM AND DEVICE FOR DATA TRANSMISSION

摘要

The embodiments of present application involve the wireless communication technology, especially involve a method, system and device for data transmission. In the prior art, when a multimode Remote Radio Unit (RRU) accesses the master station side, it is difficult to know the interface standard of the master station side, which causes unable to transmit data according to the data format corresponding to the interface standard of the master station side; consequently the data transmission difficulty is increased, and the success rate of the data transmission is reduced, the embodiments of present application are used to solve this existent problem. The method of present application embodiments includes that: the Building Baseband Unit (BBU) confirms the used interface standard of the interface connected with the RRU; according to the confirmed interface standard, said BBU sends an interface standard indication message to the RRU connected with the BBU itself; the RRU connected with the BBU itself is indicated to confirm the interface standard according to said interface standard indication message, and to transmit data using the data format of the confirmed interface standard. Using the embodiments of present application, the success rate of the RRU to access the master station can be enhanced.
