Abstract
KPI indicators of traditional user perception system can not accurately reflect user's perception. Based on the monitoring of Iu-PS interfaces, this paper describes a kind of user perception system of PS domain of TD-SCDMA network. Multi-index set, Multi-dimensional analysis and weight set are adopted to evaluate user perception. Through message decoding, CDR (call data record) synthesis and user perception model foundation, we can evaluate the sense of user perception synthetically, and it is applicable for fault location. First and foremost, the paper focuses on CDR synthesis algorithm and user perception model. According to the test of network data,it is verified that the test result is correct,and the effect is good.
