摘要
在分析了合法侦听原理的基础上分析了合法侦听的接口HI1,HI2,HI3三种不同接口实现不同的功能。HI1主要实现鉴权,HI2主要实现被侦听用户的活动信息传送,HI3则是实现被侦听用户的通信内容的传送。根据三种接口给出了GSM系统的合法侦听体系结构和实现GSM合法侦听的系统模型。
The lawful interception interface should be provided by network operator or facility provider. The article analyses the lawful interception handover interface after tells the lawful interception roles relation. The handover interface have three kinds: HIj, HI~ and HI3 , which are interface for administrative information, interface for IRI and interface for CC. Then the article presents the lawful interception architecture of GSM and the model of implement lawful interception.
