TD-SCDMA测试仪中Iub接口CDR的合成方案

Scheme of CDR synthesis on Iub interface in TD-SCDMA network analyzer

CDR合成属于网络测试仪的基础功能部分。对TD-SCDMA系统的Iub接口信令进行了深入分析和研究,并以MOC的信令流程为例,提出了在Iub接口上实现消息归类,多协议关联的CDR合成方法,并具体应用到重庆邮电大学通信网与测试技术重点实验室的TD-SCDMA网络测试仪中,效果良好。该CDR合成方案同样实用于WCDMA系统。

CDR synthesis is a basic function of network analyzer. This paper gives a detailed analysis and research on signalling of the Iub interface in TD-SCDMA system. On the basis of the signalling procedure in MOC, the CDR synthesis method of messages classification and multi-protocol association is presented. This scheme, which also does well in WCDMA system, was implemented in the TD-SCDMA network analyzer that made by the Key Lab on Communication Networks and Testing Technology of Chongqing University of Posts and Telecommunications and got good results.
