System for interception of digital cellular phone communication
First Claim
1. An interception system, comprising:
- a cellular phone including registration identification means capable of remote communication via a cellular network connected to an activating interception device;
said activating interception device operable for transmitting an activation message to said cellular phone including registration identification means for activating said cellular phone interception procedure;
said activation message including information rerouting remote communication through at least one listening point or at least one intercepting phone such that initiation of remote communications by said cellular phone including registration identification means with an intended recipient causes transmission of said remote cellular communication through at least one said listening point or at least one said intercepting phone.

Abstract
A system for interception of digital cellular phone communication which is required by Communication Assistance for Law Enforcement Agency CALEA. The system includes a plurality of wide area networks which control the transmission of voice, data, file and other types of messages in a reconfigured exchange area, each area network including a plurality of air interface Base Station (BS) controlled by a central regional service point Mobile Switch Center (MSC) which is connected to an activator unit. The activator is a computer based system controlled by microprocessor and having database for permanently and temporarily storing predetermined cellular phone subscribers information and messages from and intendant for selected end users. The activator communicates with other wide area network via a physical communication network which provides communication links between the networks and the end users whether wireless or wired.

7. A method for intercepting communication between a cellular phone and an intended recipient over a communication network, said method comprising:
-
registering said cellular phone with said communication network;
said registered cellular phone transmitting a message to said cellular communication network including a portion of said message connecting to at least one listening point or at least one intercepting phone and a portion of said message indicative of an activation signal enabling interception;
storing said message corresponding to at least one said listening point or at least one said intercepting phone and said activation signal in memory within said cellular phone;
initiating communication at said cellular phone to said intended recipient over said communication network through at least one said listening point or at least one said intercepting phone;
checking said second portion of said message in memory to determine whether said interception is enabled;
retrieving from memory said portion of identification means associated with at least one said listening point or at least one said intercepting phone and utilizing at least one said listening point or at least one said intercepting phone to establish communication between said cellular phone and said intended recipient phone number. - View Dependent Claims (8, 9, 10, 11, 12)
utilizing at least one said listening point or at least one said intercepting phone to establish communications between said cellular phone and at least one said listening point or at least one said intercepting phone comprises establishing a conference call between the user of said cellular phone, said intended recipient phone number and at least one said listening point or at least one said intercepting phone.

11. The method according to claim 7, wherein said communications network comprised a digital cellular network.
-
12. The method according to claim 7, further comprising the step of providing a simulated RF interface for generating a high powered control signal to said cellular phone to cause said cellular phone to initiate registration.
-
13. An interception system for enabling digital cellular communication between a target cell phone and an intended recipient phone to be directed to at least one said listening point or at least one intercepting phone, said system comprising;
-
activation means for providing a signal indicative of a third party phone number corresponding at least one said listening point or at least one said intercepting phone;
communication means responsive to said signal for transmitting said third party phone number to said target cell phone;
memory means for storing said third party phone number; and
means responsive to a communication signal indicative of a request to establish communication with said intended recipient phone for retrieving said third party phone number and initiating communication to at least one said listening point or at least one said intercepting phone. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
