Graded-Service Arrangements TRIZ Cases
- Network Admission Control Using Historical Session Criteria
Historical session performance and endpoint-specific criteria screen automated calls before resource allocation, reducing congestion and failed setups.
- Kiosk-Based Video Visitation with PID Camera Isolation
A fixed kiosk captures and displays all call video while the inmate device camera is disabled to block unauthorized visual data.
- Call Authentication Using Device Identifiers to Reduce Verification Time
This case maps devices to user profiles in advance, enabling secure call authentication without transmitting personal information.
- Wireless Mediation Module for Time-Aware Contact Initiation
Mediation module queries recipient local time to present contact options, avoiding disturbances from inappropriate timing.
- Revenue Management System for Penal Call Tariff Validation
A revenue management system validates call destinations against multiple carrier databases to ensure correct billing classification.
- VoIP Call Interruption for Unauthorized Access Prevention
A VoIP monitoring system interrupts suspicious calls to prompt user verification.
- Incoming Communication Processing System for Controlled Facility Access
An incoming communication processing system manages voice, text, and video calls to residents within controlled facilities.
- Server Telephone Number Registration via Call Approval
A server device registers telephone numbers by sending approval requests during incoming calls.
- Emergency Call Bypass on Screen-Locked Mobile Terminals
Segmented emergency call buttons bypass screen locks to reach user-defined contacts, while GPS modules transmit location data when calls fail.
- Controlled-Environment Facility Resident Interface for Multitasking
A resident interface enables app switching via hardware buttons or selectable indicators on communication devices.
- DTMF Signal Evaluation for Unauthorized 3-Way Call Detection
A telephone network node compares characteristics of initial and subsequent DTMF signals to verify authorized parties.
- Telephony Authentication via Voice Signal Sampling and Comparison
Sampling voice signals generates test data sets compared over a secure channel to prevent identity theft during communication.
- Mobile Device Group Control Mode for Call Disruption Management
Group control mode applies location and time rules to mobile devices.
- Smart Card Remote Personalization via Temporary Keys
A smart card personalizes credentials remotely using temporary authentication keys exchanged with a home location register.
- Voice Characteristic Analysis for Fraud Detection Without Caller ID
Detects fraud via voice analysis distributions, bypassing caller ID spoofing to secure advertising incentives.
- Inmate Wi-Fi Communication System with Automated Contact Verification
Automated contact list verification and routing eliminate manual staff intervention, reducing communication delays while maintaining secure privacy.
- Digital Signal Splitting Using Prosodic Feature Extraction
Processor splits digital signals into true prosodic units using calculated onset value locations, eliminating reliance on complex speech transcription systems.
