基于HDLC协议的光网络通信分析与实现

Analysis and implementation of optical network communication based on HDLC protocol

针对移动通信系统中基带处理单元+射频拉远单元的分布式基站架构的主流趋势,分析了HDLC协议的帧结构,通过MPC852T和XC5VLX50T完成了光收发模块的控制和数据交换,实现了BBU和RRU的信令交互。该设计已经在4G基站产品中大规模应用,结果表明光网络通信稳定、可靠,其可能对5G基站和其他光网络通信开发具有参考价值。

In view of the mainstream trend of BBU+RRU distributed base station architecture in mobile communication system,the frame structure of HDLC protocol is analyzed.Through MPC852 T and XC5 VLX50 T,the control and data exchange of optical transceiver module is completed,and the signaling interaction between BBU and RRU is realized.The design has been widely used in 4 G base station products,and the results show that the optical network communication is stable and reliable,which may be of reference value to the development of 5 G base station and other optical network communication.
