CPRI and ECPRI protocol data fusion transmission method

Abstract

The invention relates to a CPRI and ECPRI protocol data fusion transmission method, which comprises the following steps of S1, acquiring CPRI protocol data of 4G signals and ECPRI protocol data of 5G signals in real time, in a CPRI synchronous transmission protocol, transmitting data by taking a data block as a unit, and in an ECPRI asynchronous transmission protocol, transmitting data by dividing the data into groups according to bits; and S2, according to the judgment of the signal priority, balancing the lagging degree of the 4G signal and the 5G signal, realizing the fusion of the CPRI protocol data of the 4G signal and the ECPRI protocol data of the 5G signal, and furthest applying transmission resources on the basis of balancing the data transmission efficiency of the two protocols. According to the invention, the 5G + 4G dual-mode base station equipment is adopted, CPRI and ECPRI protocol data can be transmitted forward at the same time in a 10G optical module transmission bandwidth, forward transmission bandwidth resources are saved, the construction cost of a 5G + 4G network is reduced, the transmission efficiency is improved, and the transmission resources are applied to the maximum extent on the basis of balancing the data transmission efficiency of the two protocols.

technical field [0001] The present application relates to the technical field of communication protocols, in particular to a data fusion transmission method of CPRI and ECPRI protocols. Background technique [0002] With the development of the 5G communication network, the carrier bandwidth and the number of antennas have increased significantly, and the amount of data transmitted between the BBU and the RRU has increased dramatically. At the same time, the 5G network and the 4G network are co-located, and the use of 5G+4G dual-mode base station equipment is also increasing. More and more, the current high-speed optical modules cannot take into account the dual-mode transmission data traffic of 5G+4G, and the cost of separate transmission is high, and the 5G network communication protocol mainly adopts ECPRI, while the 4G network communication protocol mainly adopts CPRI, and the two protocols are incompatible, resulting in The data transmission efficiency between 5G+4G dual...

[0002] With the development of the 5G communication network, the carrier bandwidth and the number of antennas have increased significantly, and the amount of data transmitted between the BBU and the RRU has increased sharply. At the same time, the 5G network and the 4G network are co-sited, and the use of 5G+4G dual-mode base station equipment is also increasing. More and more, the current high-speed optical modules cannot take into account the dual-mode transmission data traffic of 5G+4G, and the cost of separate transmission is high, and the 5G network communication protocol mainly uses ECPRI, while the 4G network communication protocol mainly uses CPRI. The two protocols are not compatible, resulting in The data transmission efficiency between 5G+4G dual-mode base station equipment is low and the cost is high
