Systems and methods for communication protection
First Claim
1. A system for preventing unauthorized communication, the system comprising:
- a mobile unit having a static mobile unit identifier that uniquely identifies the mobile unit, the mobile unit generating a first random identification number, the mobile unit storing the first random identification number;
a base station in communication with the mobile unit; and
a central control in communication with the base station, the central controlgenerating a second generated identification number from a use of a table associated with the static mobile unit identification number and communicating the second generated random identification number to the base station,wherein the base station receives the first random identification number from the mobile unit and compares the first random identification number to the second generated random identification number, thereby providing security, andwherein the first random identification number is updateable, and is updated with each call based on the static mobile unit identifier, at a periodic time interval, and/or upon an occurrence of a triggering event.

Abstract
A communications system and method is provided to reliably protect communication systems, such as mobile phone systems, from unauthorized use, as well as to make the interception of wireless communication more difficult. Specifically, the static wireless phone number or other similar identifiers are not used for identification and authorization during communication between the mobile unit and a base station. Instead, a set of private identifiers is determined and is known only to the phone company and the base stations controlling the mobile phone calls. These private identifiers allow dynamic and continual updating of the mobile phone and base station directories with current valid identifiers that are used for communication between the devices.
