摘要

提出了一种干扰GSM通信的新方法。其目的是降低语音连接质量，从而使用户无法相互理解，同时保持已建立的连接。干扰方法的参数取决于在SACCH帧中实现的算法特性。实验证明，对于三种移动电话编解码器，由于GSM通信信道的干扰，有可能达到令人不满意的语音连接质量MOS<2。在无干扰的情况下，数据传输错误也会导致语音连接质量下降，并对这种影响进行了分析。将该方法的性能与其他方法进行了比较。

An investigation of a new GSM systems jamming technique without existing connections disruption

This paper presents a new method for jamming of GSM communications. The aim is to decrease voice connection quality, thus disabling users to understand each other, while keeping established connections. The jamming method parameters depend on the algorithm characteristics implemented in SACCH frame. It is proved for three mobile telephony codecs that it is possible to reach unsatisfactory voice connection quality MOS<2 due to jamming of a GSM communications channel. Errors in data transmission during the periods without jamming also cause voice connection quality impairment and this influence is analyzed. The method performances are compared to other solutions.

期刊介绍： The TELFOR Journal is an open access international scientific journal publishing improved and extended versions of the selected best papers initially reported at the annual TELFOR Conference (www.telfor.rs), papers invited by the Editorial Board, and papers submitted by authors themselves for publishing. All papers are subject to reviewing. The TELFOR Journal is published in the English language, with both electronic and printed versions. Being an IEEE co-supported publication, it will follow all the IEEE rules and procedures. The TELFOR Journal covers all the essential branches of modern telecommunications and information technology: Telecommunications Policy and Services, Telecommunications Networks, Radio Communications, Communications Systems, Signal Processing, Optical Communications, Applied Electromagnetics, Applied Electronics, Multimedia, Software Tools and Applications, as well as other fields related to ICT. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies towards the information and knowledge society. The Journal provides a medium for exchanging research results and technological achievements accomplished by the scientific community from academia and industry.
