(i) a transceiver that communicates with a cellphone tower to communicate voice and data signals to or from other cellphones, said transceiver not communicating any said data describing said zones, corners or bits,(ii) a microphone that inputs audio signals,(iii) a speaker that outputs audio signals,(iv) a keyboard wherein telephone numbers can be dialed and data can be entered,(v) a display where at least said telephone number being dialed can be displayed,(vi) a ringer that outputs a ring tone, and(vii) (optionally) a camera where a picture or a video can be taken,(g) a GPSS system disposed within and coupled to said cellphone that outputs coordinates of said cellphone'"'"'s current location,(h) a cellphone memory, disposed within said cellphone and storing, at least in part, said polygon'"'"'s corner'"'"'s coordinates and said of polygon'"'"'s bits, said stored data not including said cellphone users'"'"'personal data, nor data being provided in response to said cellphone user having an accident, and said stored data not being any part of a message'"'"'s zone address,(j) a processor that initializes said memory with data describing said zones, polygons, polygon'"'"'s corners and bits in the zone, and then repeatedly executes forever a single loop program,(k) a single pass of said single loop program that repeatedly reads each said zone'"'"'s data, read one zone at a time from said memory, to compare it to the cellphone location obtained from said GPS system,wherein, if said cellphone is in said zone, said processor, responsive to said zones'"'"' data bits, initiates, enables, disables or restores operations in said cellphone'"'"'s components.

Abstract
A system and method are described for initiating, enabling, disabling or restoring cellphone operations when the cellphone is in a zone, which is where cellphone operation has to be so altered. A courtesy signal transmitter transmits a courtesy signal containing zone data, which is received by the cellphone'"'"'s courtesy signal receiver. A GPSS receiver, embedded in the cellphone, outputs the current cellphone location. A cellphone'"'"'s processor compares this location to the zone'"'"'s coordinates; if it determines that the cellphone is in the zone, the cellphone'"'"'s processor initiates, enables, or disables operations in it as directed by bits in the zone'"'"'s data. Spread-spectrum technology securely passes zone data from courtesy signal transmitters to courtesy signal receivers in cellphones, using GPSS data to make this coding scheme more secure. Finally, the courtesy signal transmitter GPSS location is checked to determine if the courtesy signal transmitter has been moved after it is initialized.

15. A method for initiating, enabling, disabling or restoring operations within a cellphone system when said cellphone is in a zone;
- comprising the steps of;
(a) specifying zones, each of which is a geographic area, such as an auditorium, wherein cellphone operations need to be initiated, enabled, disabled or restored together, (b) deriving bits needed to execute said initiating, enabling, disabling or restoring in cellphones within said zone, (c) for each said zone, selecting one or more geometric three-dimensional concave polygons that are collectively coextensive with said zone, each said polygon having a plurality of corners, (d) deriving GPSS coordinates of all said corners, (e) placing courtesy signal transmitters such that each of said polygon'"'"'s corner'"'"'s coordinates be under the cover of at least one courtesy signal transmitter, but such that no two said courtesy signal transmitter signals interfering with each other, said transmitter'"'"'s cover being a largest surface of a contiguous volume in which anywhere in the volume a courtesy signal transmitted from said courtesy signal transmitter is of sufficient power to probably be correctly received and decoded in a courtesy signal receiver disposed in said cellphone, (f) storing, in said courtesy signal transmitter'"'"'s memory, data describing each said zone under its cover, each data comprising GPSS coordinates describing the position of said zone'"'"'s polygon'"'"'s corners, and bits to initiate, enable, disable or restore cellphone operations in said zone, (g) a cellphone user using a cellphone, comprising steps of (in any order); (i) communicating with a cellphone tower using a transceiver, (ii) receiving audio signals through a microphone, (iii) outputting audio signals through a speaker, (iv) dialing telephone numbers and entering data using a keyboard, (v) displaying data such as said telephone number, (vi) producing a ring tone with a ringer, or (vi) (optionally) taking a picture or video with a camera, (h) receiving said cellphone'"'"'s current location coordinates from a GPSS receiver incorporated in said cellphone, (j) receiving courtesy signal data from said courtesy signal transmitter'"'"'s memory through courtesy signal receiver disposed in said cellphone, (k) writing said received courtesy signal data in a cellphone'"'"'s memory, said memory not storing said cellphone users'"'"' personal data nor data responsive to an emergency wherein said cellphone user has an accident, (m) determining if said current cellphone location obtained from said GPSS receiver output is in said zone whose data is stored in said cellphone'"'"'s memory and, (n) if said cellphone is in said zone, initiating, enabling, disabling or restoring said user'"'"'s said cellphone operations, responsive to said zone'"'"'s bits to initiate, enable, disable, or restore cellphone operations of said cellphone user using a cellphone. - View Dependent Claims (16, 17, 18, 19, 20)
