Telephonic Communication TRIZ Cases
- Mobile Device Location Estimation Using Wireless Access Gateways
A mobile device estimates its position by scanning wireless access gateways and assigning weights to their detected locations.
- Digital Assistant Intercom Device Arbitration via Acoustic Fingerprinting
Acoustic fingerprint clustering maps users to optimal intercom devices, excluding poor-signal units to eliminate cross-talk in multi-user environments.
- Timesharing Low Power Modes Bit Loading Optimization
A timesharing protocol selects bit loading tables based on active lines to manage low power modes in discontinuous communication systems.
- Network Resource Brokering via Dynamic Bidding
Dynamic bidding ranks entities to monetize infrastructure investments while adapting charging parameters.
- Secure Profile Activation for Mobile Data Connectivity
A mobile application requests activation of a secure cellular profile to establish data transmission.
- SIP Session Setup Suspension for Charging Control
A precondition framework suspends SIP session setup until supplementary services provide charging information.
- Network Apparatus Authentication for SIM-Free Terminals
Network apparatus checks model identifiers against stored authentication data to prevent unauthorized access by unverified terminals.
- Wireless Positioning Using Relevance Indicators to Reduce Computational Load
A positioning method uses relevance indicators to select relevant sample points for location estimation.
- RFID Wireless Control of Instant Messaging Sessions
Wireless signaling device detects user proximity to automatically activate or deactivate instant messaging sessions without manual input.
- Centralized Line Digital Signal Processing for Copper Access
Consolidating line digital signal processing into a single device reduces hardware complexity and operation costs while maintaining multi-mode service recovery.
