A No-Jamming Selective Interception System of the GSM Terminals
Kan Zhou, Aiqun Hu, Yubo Song · 2010
This paper presents a new interception system which is intended to be placed in a restricted area for security purpose. It can get the unique identity, such as IMSI, of passed mobile phones, and further check these identities in a local cache to selectively block the communication of these phones. We will analyze the GSM protocol which is relevant to the interception system and later present the performance of such a system by real tests and demonstrate its feasibility.
