Abstract

The embodiment of the invention provides a data conversion method and device between a CPRI interface and an eCPRI interface. The method comprises the following steps: performing CPRI frame decoding on CPRI frame data obtained from a CPRI interface to obtain a CPRI frame header, first IQ data and first OAM data; and obtaining an eCPRI frame header according to the CPRI frame header, packaging theeCPRI frame header, the first IQ data and the first OAM data into eCPRI frame data according to a frame structure of the eCPRI, and sending the eCPRI frame data to an eCPRI interface. The embodiment of the invention provides a data conversion method and device between a CPRI interface and an eCPRI interface. Data conversion between an eCPRI interface and a CPRI interface can be realized, 4G equipment can compatibly transmit 5G signals without modifying hardware equipment, a 4G network can be upgraded to a 5G network without rewiring construction, and the construction cost of the 5G network canbe greatly reduced.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a data conversion method and device between a CPRI interface and an eCPRI interface. Background technique [0002] The CPRI interface (Common Public Radio Interface) is a key communication interface between REC (Radio Equipment Control) and RE (Radio Equipment) widely used in cellular wireless networks. Because it uses optical fiber transmission, it has the advantages of low construction cost, flexible networking, long distance and wide coverage, and is widely used in BBU (baseband processing unit) and RRU (radio remote unit) of 3G / 4G base station equipment data transfer between. With the advent of the 5G era, due to the substantial increase in the carrier bandwidth and the number of antennas, the data traffic transmitted between the BBU and the RRU has increased sharply. At the same time, the high cost of high-speed optical modules has made the traditional CP...
