SYSTEM FOR PROVIDING HIGH-EFFICIENCY PUSH-TO-TALK COMMUNICATION SERVICE TO LARGE GROUPS OVER LARGE AREAS
First Claim
1. A method of providing a communication to a receiving device, comprising:
- converting a first audio utterance into a text based message; and
transmitting, via a text delivery optimized communication network, said text based message;
wherein said text based message is transmitted, via a broadcast optimized communication network, to at least one receiving device to convert said text based message into a second audio utterance.

Abstract
A system, various methods, and a specific apparatus are provided for the purpose of supporting push-to-talk (PTT) service for a very large group featuring a significantly higher number of listeners than the number of potential talkers, as well as a constrained vocabulary in normal usage. The invention takes advantage of speech-to-text and text-to-speech conversion in end user devices for maximum utterance compression. The invention uses the Iridium Mobile Satellite Service (MSS) system and its Short Burst Data (SBD) service for unicast transmission of talker utterances to a PTT Server, and the same system'"'"'s Global Data Broadcast (GDB) service for multicast retransmission of utterances from the PTT Server to an effectively unlimited number of listeners. The PTT Server provides priority ordering and preemption as necessary when multiple talkers provide near-simultaneous utterances, effectively managing the floor without interactive protocols among the talkers.
