Systems and methods for detecting and controlling transmission facilities
A method of detecting, controlling and managing transmission of a transmitting device within a facility is disclosed. The method involves transmitting information to the transmission device, detecting a response transmission from the transmission device by a least one transmission detection facility, extracting identification information associated with the transmission device in response to the transmitted information; and determining a location of the transmission device based on the response transmission received by the at least one received transmission detection facility, wherein the response transmissions are sorted by the identification information, determining an allowability of the located transmission device with the set area and interacting and manipulating transmission of the detected transmitting device.
1. A method, operable in a processing system, for capturing a transmission facility within a set area, said method causing said processing system to execute the steps of:
receiving a reference signal from a base station and a signal from said transmission facility;
determining an expected received power of the reference signal at said transmission facility, said expected received power being determined based on a distance between the transmission facility and the processing system and a positional relationship among said base station, said transmission facility and said processing system;
transmitting a simulated reference signal, the simulated reference signal having a higher power at said transmission facility than the expected received power, wherein said simulated reference signal causes said transmission facility to re-acquire communication with said base station;
establishing communication with the transmission facility when said transmission facility attempts to re-acquire communication with said base station;
receiving a transmission from the transmission facility to re-acquire communication with said base station;
extracting from said transmission to re-acquire communication with said base station identification information associated with said transmission facility;
determining an allowability of the transmission facility to receive and transmit signals within said set area based on said identification; and
providing said indication of allowability to the base station, wherein in response to an indication of not allowed, the base station displays an indication of the not allowed transmission facility and denies service to the transmission facility by holding the transmission facility to a non-communication channel.
2. The method of claim 1 wherein said identification information comprises at least one of: a transmission frequency, a transmission identification number, a transmission time of arrival, a transmission type, a transmission characteristic, a transmission location, a transmission amplitude, a transmission width, a transmission frequency range and a unique identifier.
3. The method of claim 1 , further comprising:
determining a location of said transmission facility based on at least one of: an amplitude received on at least one receiving antenna, an amplitude received on one receiving antenna with a known angular orientation, a GPS technology, a time difference of arrival at a plurality of receiving antenna, an angle of arrival at at least one receiving antenna, and a map-based location.
4. The method of claim 1 , wherein said simulated reference signal is a command signal instructing said transmission facility to re-acquire communication with said base station.
5. The method of claim 4 , wherein said command signal is a discrete signal.
6. The method of claim 1 , wherein the step of determining allowability comprises:
determining whether an identification of said transmission facility is contained within an allowability file; and
indicating allowability when said identification is contained within said allowability file.
