获取4G用户身份信息的设计与实现

Design and implementation of obtaining 4G user identity information

移动通信的快速发展给人们生活带来便利的同时也带来了网络安全问题,再加上4G网络的普及,相比传统回落2G网络的复杂性以及严重影响用户的上网质量,提出了一种获取4G用户身份信息的设计方案。利用LTE网络,UE随机接入流程以及跟踪区周期性更新的原理,通过4G移动终端与4G基站之间的空口信令交互,实现了在用户无感知的情况下,达到实时、精确地对4G用户身份信息IMSI和IMEI的实时获取。实验测试结果表明,本方案设计能够获取到4G基站覆盖范围内用户接入的身份信息,从而方便地对4G用户身份信息的监控与管理。

The rapid development of mobile communication brings convenience to people＇s lives at the same time also brought the network security problems,coupled with the popularity of 4G networks,compared to the traditional 2 G network complexity and serious impact on the user＇s Internet quality,this paper proposes a design scheme to obtain the identity information of 4G user. The use of LTE network,UE random access process and the principle of periodic update of the tracking area,through the 4G mobile terminal and 4G base station between the air interface signaling interaction,achieves the user without awareness of the case,real-time,accurate 4G user identity information IMSI and IMEI real-time acquisition. The experimental results show that the scheme can be designed to obtain the identity information of the user access in the coverage area of the 4G base station,so as to facilitate the monitoring and management of 4G user identity information.
