Based on SIP telephony network, this paper discusses the design and implementation of a prototype system for lawful interception and analyses the reference model and functional modules of the system. Finally, the operational flow of the prototype system is presented. 针对SIP电话网络,讨论了合法侦听原型系统的设计与实现,并系统地分析了原型系统的参考模型及其模块实现,最后,给出了原型系统的运行流程。
