TD-SCDMA测试仪中Uu接口的RRC消息关联方案研究

Research of RRC layer association on Uu interface in TD-SCDMA network analyzer

在TD无线网络测试中,测试仪表的空中接口的数据解码和分析质量有着举足轻重的作用。RRC子层在空中接口中属于接入层,空中接口的相关功能的实现,如无线承载的建立和实现等都是在RRC信令连接的基础上进行的,因此RRC子层消息的关联是空中接口呼叫合成的关键所在。本文以MOC信令流程为例,根据RRC信令连接是否建立在专用信道上,对专用信道和公共信道上建立的RRC消息分别提出了相应的关联方案。经过测试,该方案确实可行,达到了研究的预期目的。

The quality of the test in TD radio access network depends on the quality of the data-decode and data-analyze function of the analyzer on Uu interface. The RRC sub-stratum belongs to Access Stratum（AS）. The realization of the Uu interface＇s functions are based on the establishment of signaling connection of RRC protocol. So the RRC protocol association is the key to the call data record of the Uu interface. This paper gives a scheme of RRC protocol association on the basis of the signaling procedure in MOC. After testing with particular data, the scheme is proved to be available.
