摘    要:深入研究了在TD-SCDMA系统中对Uu接口协议栈进行信令监测的方法。给出了NodeB节点的用户平面和Uu接口控制平面的结构模型和公共传输信道传输格式的确定方式,分析了Uu接口协议栈RLC协议的分段重组过程。在此基础上提出了从Iub接口FP协议数据帧中得到Uu接口协议栈数据,实现信令监测的一种算法。该算法的程序模块在实际环境下进行了测试,结果说明,运用该算法能够在Iub接口准确地、完整地监测和分析Uu接口的信令消息。

关 键 词:Iub接口  Uu接口  FP  MAC  解码

Abstract:The procedure of signalling monitoring on Uu interface protocol stack in TD-SCDMA system is deeply researched. A brief introduction to structure of the user plane of Node B and control plane of Uu interface as well as the way to get transport format on common transport channel is presented. Furthermore, the procedure of segmentation and reassembly of RLC message in Uu interface stack is analyzed. Then, on the basis of it, the algorithm for getting Uu data from FP data frames of Iub interface and implementing signalling monitoring is proposed. The program module of this algorithm is tested in practical environment and the result shows that it is capable of monitoring and analyzing signalling messages of Uu through Iub monitoring.
Keywords:Iub interface  Uu interface  FP  MAC  decode
