This invention establishes a sophisticated system for authorizing wireless telephone communications. It involves maintaining two sets of authorized telephone numbers: one supplied by the customer and another derived from paid customer bills. The system analyzes the transmission characteristics of unauthenticated cellular telephones, verifying their authenticity against stored reference waveforms. If the analysis is negative, the system can still authorize the call if the number dialed matches an authorized number. Additionally, it has a technique to modify reference waveforms to adapt to changes in transmission characteristics.

The second patent is the **"Apparatus and Method for Preventing Fraudulent Calls in a Wireless System."** This patent presents a detection system for fraudulent use of wireless telephone systems. It employs a fingerprint analyzer to classify unauthenticated wireless telephones as either authorized or fraudulent. Each authorized telephone has a specific valid destination list of considered valid call destinations. The system can classify a call request as valid even if the fingerprint analysis indicates it as fraudulent, provided the destination is on the valid list. It also maintains invalid and suspicious destination lists, enhancing its fraud prevention capabilities.
