Dual fallback hardened VoIP system with signal quality measurement
First Claim
1. A system for providing hardened VoIP and land mobile radio communication services to mobile devices, the system comprising:
- a mobile device having a first primary operational state, a secondary primary operational state a first fallback state, and a second fallback state,the mobile device configuredin the first primary operational state toreceive via a cellular communications systema VoIP status signal from a controller,receive from a first land mobile radio systema first Land Mobile Radio (LMR) status signal, andprovide VoIP communication over the cellular communications system;
in the second primary operational state toreceive via the cellular communications systemthe VoIP status signal from the controller,receive from a second land mobile radio systema second LMR status signal, andprovide VoIP communication over the cellular communications system;
in the first fallback state toprovide voice communication over the first land mobile radio system;
in the second fallback state toprovide voice communication over the second land mobile radio system; and
to transition from the first primary operational state to the first fallback state upon failing to receive the VoIP status signal from the controller;
to transition from the second primary operational state to the second fallback state upon failing to receive the VoIP status signal from the controller; and
to transition from the first primary operational state to the second primary operational state upon failing to receive the first LMR status signal.

Abstract
A hardened VoIP system is presented that includes secure push-to-talk voice functionality. Through the addition of encryption, authentication, user filtering, and integration with new and existing LMR systems, a secure voice platform ensures malicious software, unauthorized access and brute force security attacks will not compromise the voice communications of the system. The VoIP system is engineered to ensure graceful system degradation in the event of maintenance activities, natural disasters and failure modes. The hardened VoIP system offers the functions a LMR trunking system while utilizing broadband connections. Private calls, group calls, Emergency Alarms with covert monitoring capability, scanning and priority scanning may be incorporated into the system. The system includes a VoIP controller that serves as a trunking controller, manages available VoIP based conference bridges, and assigns them as needed to the parties involved in each voice call. The system includes multiple fallback methods that may be prioritized based on pre-failure analytics.
