摘要
介绍了会话启动协议(SIP)系统和合法侦听(LI)的原理及要求,在提出分布式合法侦听架构的基础上,设计了SIP系统的分布式侦听模型,该侦听架构符合合法侦听要求,并对SIP系统的分布式侦听模型的丢包率、性能进行了测试比较。
The SIP system and lawful interception （LI） principle were proposed. Based on the proposed architecture of a distributed LI system, a prototype of a distributed system for lawful interception in SIP network was built. The architecture we proposed met the requirements which a lawful interception system must fulfill. The rate of packet lost and the perofrmance of the mode of distributed interception system in SIP network were tested and compared.
