近年来,围绕移动通信的窃密问题越来越严重,国家出台了一系列规定限制涉密场所手机的使用。目前常用的手机防护技术主要为屏蔽和干扰,对于大型会议场所,采用手机屏蔽产品不便于管理,而干扰技术存在干扰效果不佳,干扰边界难于界定等局限性。本文提出了一种利用虚拟基站技术对手机进行管控的防护方式,结合屏蔽电缆技术可以较为精确地控制防护边界,在一定程度上解决了过防护与欠防护的问题。 In recent years, the issue of theft of mobile communications has become more and more serious. China has promulgated a series of regulations to restrict the use of mobile phones in classified places. At present, the commonly used cell phone protection technologies are mainly shielding and interference. For large conference venues, the use of cell phone shielding products is inconvenient to manage, and the interference technology has poor interference effects and the interference borders are difficult to define. This paper presents a virtual base station technology to control mobile phone protection methods, combined with shielded cable technology can be more precise control of the border protection, to a certain extent, over-protection and under-protection issues.
