中国移动用户对通话质量的要求越来越高，通话区域也日益广泛和复杂。识别用户通话中的具体场景，建立有效的用户行为模型，进行针对性的网络优化，是挽留客户的重要手段。本文研究的内容，首先在Nb/Mc接口以镜像的方式采集信令和媒体，分析数据所包含的用户位置信息；然后运用统计的方法建立不同用户场景的行为模型；最后使用该模型对全网的移动用户进行场景分类，进行通话质量的分析。

China Mobile users are demanding higher call quality increasingly, communication area becomes more broad and complex too. Identify the users specific call scenario create a valid user behavior model, targeted network optimization, which is an important means to retain customers. This paper research, fi rstly, collected signaling and media by the mirror way on Nb/ Mc interfaces, analyzed users location information included in the data, then created different user scenarios behavioral model by using statistical methods, fi nally using the model of the mobile user's entire network for scene classifi cation, and analyzed the communication quality.
