Abstract

The invention provides an interface switching device. Base band data and control information are transmitted between a CRAN (Cloud Radio Access Network) server and the interface switching device through an UDP data packet, the synchronization is realized, and switching from a 10GE interface to a CPRI (Common Public Radio Interface) between the CRAN server and an RRU (Remote Radio Unit) is realized. The interface switching device provided by the embodiment of the invention enables networking to be flexible, simple and convenient, is easy to realize, and reduces the networking cost.

Description

technical field [0001] The invention relates to an interface switching device and method, in particular to an interface switching device and method between a 10GE interface (ie, a 10 Gigabit Ethernet interface) and a CPRI interface (Common Public Radio Interface, ie, a common public radio interface). Background technique [0002] The CPRI interface is used for the transmission of user data, control information, management information and synchronization information between the REC (Radio equipment controller) and the RE (Radioequipment, wireless equipment). The CPRI interface supports the following types of data streams: IQ data , the data format under in-phase and quadrature modulation used by user platform information, including I data and Q data; synchronization information, synchronization data for frame and time adjustment; L1 control protocol data: used for system startup, physical layer link Maintains the transmission of time-critical information closely linked to phy...
