Abstract

本发明涉及在采用射频单元拉远的集中式基站系统中用于MU与一个或多个RRU之间使用SDH/OTN进行信号传输的方法，包括：将MU与RRU之间的通信接口分成用户平面和控制平面，其中，用户平面主要承载有关用户数据的I/Q采样数据，而控制平面主要承载有关控制信令的数据；将用户平面承载的有关用户数据的I/Q采样数据经I/Q数据帧适配层形成I/Q数据帧，再经GFP帧成帧而在SDH/OTN上传输；以及将控制平面的控制信令承载在UDP/IP和/或TCP/IP上，而将IP分组进一步承载在PPP上并由HDLC成帧，将包含控制面信令的HDLC帧经由GFP帧的控制字符通道在SDH/OTN上传输。根据本发明，由于直接利用了成熟的SDH/OTN传输网，进一步减少了信号传输的管理与维护操作同时降低了网络建设成本。
