Abstract:

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.
