Abstract

See full text

Disclosed is an interoperability gateway system that provides backup connection between a dispatch center and a Land Mobile Radio (LMR) system in the event the dispatch center is disconnected from the LMR system. In general, this may be accomplished by providing an RF link between the disconnected site and the interoperability gateway via a controller, or interoperability site network interface (ISNI), that is activated when the dispatch center is disconnected from the LMR system. The interoperability gateway provides the backup connection by allocating a control station for each channel available at the disconnected LMR system. When compared to conventional dispatch console backup schemes, the disclosed interoperability gateway system greatly reduces the equipment needed to provide dispatch console backup, thereby decreasing equipment and operation costs, and simplifying operation by providing a solution that is virtually transparent to the dispatcher.
