Method for detecting access to controlled areas and related system

摘要

Controlled area (A) is configured as a telecommunications cellular system location area, by checking connection of cellular system mobile terminals (T) to such location area (A). Connection corresponds to terminal (T) bearer access to the controlled area and can thus be used both to prevent unauthorized access and to certify and document authorized access also by interrogation through the system. The fact that terminal (T) has been kept switched on inside the controlled area despite denial can also be detected and such behavior debited to the terminal (T) involve and/or inhibited by means of temporary denial of the terminal (T)'s activation.
