Cellular device identification and location with emergency number selectivity enforcement (CILENSE)
First Claim
1. A system for restricting the operation of a radio communication device, the system comprising:
- a controller comprisinga communication module;
a security module; and
a memory;
at least three sensors, configured to be communicatively coupled to the controller and to operate within a moving vehicle, wherein the three sensors are all remotely located from all serving cellular base station sites; and
a portable wireless user control, configured to be communicatively coupled to the controller, wherein the wireless user control comprises;
a radio frequency receiver,a wireless transmitter, andat least one user input control,wherein the wireless user control and the controller are jointly configured to define at least a portion of a usage restriction zone, by actuation of the user input control when the wireless user control is at a vertex of the usage restriction zone,wherein the controller is further configured to;
determine an identity of the device by using information in a radio transmission from the device, wherein the radio transmission is received by at least one of the sensors;
determine whether the identified device is within the usage restriction zone, by using zone boundary data stored within the controller memory and transmitted radio frequency energy from the device, wherein the radio frequency energy is received by at least two of the sensors, and without requiring reception and processing of any wireless signals by the device;
receive a security code from a serving cellular base station; and
communicate the identity of the identified device to a remote node, across a public computer network, by using the received security code as an authentication credential for restricting usage of the identified device when the device is determined to be in the predefined restriction zone, wherein the restricting is enforced by a serving base station.

Abstract
A system for restricting operation of wireless devices, for example cell phones, comprises a controller and a plurality of sensors. The system restricts device usage, while permitting emergency phone calls, for example 911 calls. The sensors receive transmissions from devices, and use the transmissions for identification and determining whether a device is within a restricted zone. One disclosed method is triangulation, using time of arrival of transmissions at the sensors. If the device is within the zone, the controller sends device identification, and possibly a customized restriction request, to a remote node, for example a control node of a cell phone network operator. The operator then uses its network resources to implement the requested restrictions. Communication between the controller and the remote node is secure, possibly encrypted, to minimize malicious interference. A wireless control can define vertices of the zone and exempt certain devices from restrictions. Jamming is not required.

17. A method of restricting the operation of a radio communication device, the method comprising:
-
operating a plurality of at least three sensors within a moving vehicle; defining a usage restriction zone in a controller by actuating a user input control of a wireless user control at a vertex of the restriction zone and transmitting an indication of the actuation; in the controller, determining an identity of a device, by using information in a radio transmission from the device that is received by the sensors; in the controller, determining whether the identified device is within the usage restriction zone, by using time of arrival information from a plurality of sensors, for a radio transmission from the device, and without requiring reception and processing of any wireless signals by the device; and securely communicating the identity of the identified device from the controller to a remote node, across a public computer network for restricting usage of the identified device when the device is determined to be in the predefined restriction zone, wherein the restricting is enforced by a serving base station. - View Dependent Claims (18)
