摘　　要：针对移动通信系统话音安全问题,以非合作移动通信信号处理为基础,深入研究了WCDMA上下行话音通信协议,并通过离线分析,从第三方采集的实际空口WCDMA信号中获得了会话管理信令与话音比特。Aiming at the voice security problem of mobile communication system,based on the signal processing of non-cooperative mobile communication,this paper deeply studies the upstream and downstream voice communication protocol of WCDMA,and obtains the session management signaling and voice bits by off-line analysis of the actual air WCDMA signals collected by the third party,which provides support for the development of mobile communication information monitoring equipment.
