Substation Calling TRIZ Cases
- Priority Call Alerts in Silent Mode Using Repeat-Call Triggers
Repeated calls from priority contacts can trigger mandatory ringing or vibration in silent or DND mode, helping users avoid missed urgent calls.
- Multi-Mode Device Network-Specific Call Waiting Alerts
A multi-mode device injects network-specific alert tones to identify incoming calls from different networks without requiring screen interaction.
- CAN Bus Transceiver Ring Suppression Circuit
Transient-triggered ring suppression circuit attenuates bus terminal ringing signals during state transitions.
- Device-Side Ringtone Selector Data Generation
A ringtone service generates selector data from user behavior observations to recommend personalized audio files.
- Mobile Terminal Blocking Program for Malicious Call Prevention
A pre-embedded blocking program acquires root privilege to intercept incoming call requests in mobile terminals.
- Peer-to-Peer Communications Using Distributed Call Ledger
A peer-to-peer communications system uses a distributed call ledger to manage decentralized applications and node preferences.
- Call Context Server for Click-to-Call Information Transmission
A call context server maps transmission criteria to contextual information and transmits it during call setup.
- Interactive Ring Back Tone Service Platform for Calling Identity
A service platform coordinates dual subscription identifiers to play customized tones during call setup.
- Mobile Station Ringing Tone Continuity During LTE to 3G Transition
A mobile station control unit maintains ringing tone output during LTE to 3G transitions by tracking pre-transition audio states.
