<p>Disclosed are a data transmission method, device, and system. The data transmission method comprises: a transmission device receiving management information data based on a transmission format different from a CPRI protocol transmission format, encapsulating the management information data in a data frame based on the CPRI protocol transmission format, and sending the data frame, based on the CPRI protocol transmission format, in which the management information data is encapsulated. Therefore, information interaction between a transmission device and a transmission network management center can be implemented through an existing optical fiber or high-speed cable, so that when the transmission device is used for service data transmission between an RU and a BBU, the deployment cost and management complexity for implementing interaction of the management information data between the transmission device and the transmission network management center are reduced. Also disclosed are a data transmission device and system.</p> |
