Abstract

Periodic general broadcast messages in a public safety radio system must be manually repeated. Dis- patcher workload is increased since the same mes- sage may need to be re-broadcast several times throughout the work period. Late joining radio users will not be updated until the next periodic broadcast.

METHOD OF PROVIDING AUTOMATIC VOICE MESSAGE DELIVERY IN A TRUNKED DISPATCH RADIO SYSTEM

by Gerald Capehart and Dutch Bailey

THE PROBLEM:

  Periodic general broadcast messages in a public safety radio system must be manually repeated. Dis- patcher workload is increased since the same mes- sage may need to be re-broadcast several times throughout the work period. Late joining radio users will not be updated until the next periodic broadcast.

THE SOLUTION:

  The invention consists of a voice storage sub- system that allows dispatchers to record voice mes- sages for re-broadcast at pre-determined intervals to specified talk-group(s). Previously stored voice mes- sages are automatically re-broadcast at timed inter- vals over the trunked radio system. The message re-broadcast capability is tightly coupled, and seamlessly integrated into the radio system. Mes- sages are easily recorded since the voice storage sub- system appears as another talk-group to the dis- patcher. Messages are easily re-broadcast since the voice storage sub-system knows how to "request a

channel:' will understand a "channel grant:' and can gracemlly handle "channel busy" conditions. Dis- patcher access to the voice storage sub-system will also be made available through connections to the Public Switch Telephone Network (PSTN) or as an extension off the local Private Branch Exchange (PBX). This feature allows supervisory personnel access to the voice storage sub-system even...
