IMS中骚扰电话拦截系统的设计方案

摘要

The harassment telephone interception system is a system which provides calling harassment interception, called harassment interception and second operation interception. It also supports monitoring and control functions such as concurrency control, white list and report. It is effective in reducing harassment calls, improving the IMS phone user experience and reducing the economic loss of operators. This paper ifrstly proposes an overall architecture of harassment telephone interception system. Secondly, it focuses on the work mechanism of decision analysis subsystem and the identiifcation process of harassment telephone based on rules and statistical forms of sliding window. In the end, the intercept process of harassment telephone is presented.%骚扰电话拦截系统是一个可以对骚扰号码进行主叫骚扰拦截、被叫骚扰拦截和二次运营拦截的系统，并提供并发控制、白名单和报表等监视和管控功能。对减少骚扰号码，提高IMS电话用户的使用体验和减少运营商的经济损失有着很重要的意义。本文首先给出了骚扰电话拦截系统的系统架构，然后重点介绍了决策分析子系统的工作机理、基于规则和滑动窗口统计形式的骚扰号码识别流程，最后给出了骚扰号码拦截流程。
