Abstract

The embodiment of the invention discloses a data transmission method, a data transmission device and a data transmission system of data transmission. The data transmission method comprises the steps of using a transmission device to receive the management information data based on a transmission format different from a CPRI protocol transmission format; packaging the management information data in a data frame based on the CPRI protocol transmission format; and sending out the data frame which is based on the CPRI protocol transmission format and in which the management information data is packaged. According to the present invention, the information interaction between a transmission device and a transmission network management center can be realized by a current fiber or a high-speed cable. When the transmission device is used for the business data transmission between RU and BBU, the arrangement cost and management complexity for realizing the interaction of the management information data between the transmission device and the transmission network center are reduced. The embodiment of the invention also discloses the data transmission device and the data transmission system.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to methods, apparatuses, and systems for data transmission. Background technique [0002] The communication protocol between the radio frequency unit (RU, Radio Unit) and the baseband unit (BBU, Base Band Unit) of the wireless base station is mainly the Common Public Radio Interface (CPRI, Common Public Radio Interface) protocol, and the main content of transmission is the same phase and In-phase and quadrature-phase (IQ) data and RU-related management information and synchronization information. The traditional distributed base station RU and BBU are located at the same site, and mainly use optical fibers and high-speed cables that support the CPRI protocol to implement mutual communication between the BBU and the RU. [0003] With the development of base stations towards cloud radio access network (Cloud RAN), BBUs are centralized and large-sca...
