摘　　要：随着TD-SCDMA网络的规模商用,Iu-CS接口用户平面AAL2链路假活问题对网络的影响日益明显,如何解决AAL2链路假活故障是TD-SCDMA网络建设中的重要课题。本文通过对TD-SCDMA网络Iu-CS接口用户平面AAL2链路假活产生原因的分析,提出了一种假活故障检测处理方案,并用代码实现了检测处理算法,最后通过系统补丁方式将故障检测处理方案在某市TD-SCDMA网络中进行了测试与应用,测试与应用结果显示该方案切实可行,可以有效解决Iu-CS接口用户平面AAL2链路假活故障。With the large-scale commercial use of TD-SCDMA network, the influence of network caused by Iu-CS interface user plane AAL2 link pseudo-effect problem is serious gradually. How to resolve the failure of AAL2 link pseudo-effect is an important question. By the producing reason analysis of Iu-CS interface user plane AAL2 link pseudo-effect, this paper bring forwards a detection and disposal scheme of pseudo-effect failure, and realizes the detection and disposal arithmetic by coding. At last, the failure detection and disposal scheme is tested and applied by system patching in one city TD-SCDMA network, testing and application result proves that the scheme is feasible, can resolve availably the failure of Iu-CS interface user plane AAL2 link pseudo-effect.
