    摘要:

    终端管控技术是指在不依附于运营商和用户的前提下,通过第三方设备对通信终端进行有效控制。为了解决管控成本高、时延大等问题,提出了面向不同场景的长期演进(long term evolution,LTE)管控方案,包括全覆盖管控方案和目标终端管控方案。基于LTE终端定时同步的原理向终端发送同步诱导信号来完成对终端的吸附,构造跟踪区域更新拒绝信令和附着拒绝信令,根据信令所携带的不同核心网信息分别实现LTE终端全覆盖管控和目标终端管控。实验结果表明,提出的全覆盖管控方案能够阻断虚拟基站信号覆盖范围内所有LTE终端与外界进行通信,同时降低了管控成本。相比于传统LTE目标终端管控技术,目标终端管控方案优势在于不仅降低了管控时延,而且可以在目标用户无感知情况下完成其身份信息的检测并阻断包括长期演进语音承载(voice over long term evolution,VOLTE)终端在内的目标LTE终端与外界进行通信。

    Abstract:

    Terminal management-control refers to effective control of communication terminals through third-party devices without being attached to operators and users. To solve the problems of high cost and long delay,this paper proposes long term evolution (LTE) management-control schemes including full coverage management-control and target terminal management-control for different scenarios.Based on the principle of LTE terminal timing synchronization, synchronization guidance signal is sent to the terminal to complete the adsorption of the terminal. Tracking area update rejection signaling and attachment rejection signaling are constructed. According to different core network information carried by signaling, LTE terminal full coverage control and target terminal control are realized respectively. The experimental results show that the proposed full coverage control scheme can block all LTE terminals within the coverage of virtual base station from communicating with the outside world, and reduce the control cost.Compared with the traditional LTE target terminal management and control technology,the advantage of target terminal management and control scheme is that it cannot only reduce the control delay, but also complete the detection of the identity information of the target user and block the communication between the target LTE terminal including the voice over long term evolution (volte) terminal and the outside world.
