Cell phone control and localization for restricted facilities
First Claim
1. A method of controlling wireless communication devices within a predetermined target area comprising:
- operating a cell phone controller to scan for base station beacon signals associated with the target area,collecting identification and control data of all detected base station beacon signals,creating a beacon set appropriate for all the base station beacon signals operative within the target area, attaching operation of cell phones within the target area to the cell phone controller by conducting an active processing mode,defining the active processing mode as producing a higher level of signal power by the cell phone controller than that of an ambient signal provided by the base station,providing a radio frequency (RF) detection apparatus, including time detection recording capabilities, to determine location of a cell phone within a target area,determining the location of a cell phone within the target area by receiving a response signal from the cell phone and determining the time therefore; and
performing a query to a detection logger and recording port numbers when a time match of said time determined as a result of said response signal from the cell phone, occurs.

Abstract
A method and system for controlling cell phones and cellular phone system based wireless devices in a restricted environment, such as prisons, where the control system makes use of software defined radios to mimic the ambient wireless signals transmitted from nearby cell phone base stations. The system produces a multi-protocol beacon set based on the existing wireless environment and a pre-determined logic set to accomplish complete coverage of all relevant cell phone operating protocols. Cell phones within the desired target coverage area are then attracted to the system and their operation can be controlled. The cell phone control system is able to selectively deny or permit calls based upon a whitelist/blacklist database. The cell phone control system is interfaced to a distributed system of antennas in order to provide the proper control needed over the coverage area.

9. A system for controlling wireless communication within a predetermined target area, said system comprising:
-
at least one communication device controller interactive with a plurality of antennas associated with the target area, a radio frequency (RF) detection apparatus, including time detection recording capabilities structured to determine location of communication devices within the target area by receiving response signals from the communication devices and determining the time of the response signals being received and to log an occurrence of time matches related to the time of the response signals, said one communication device controller further structured to detect ambient signals from at least one communications base station, said one communication device controller further structured to generate a higher level of signal power than that of said ambient signal;
said higher level of signal power sufficient to attach operation of communication devices within the target area to the one communication device controller, andsaid one communication device controller structured to create a beacon set appropriate for coverage by the one communication device controller by all base station beacon signals operating within the target area. - View Dependent Claims (10, 11, 12, 13, 14, 15)
