Interoperability gateway for land mobile radio system

A system for providing backup connection between a dispatch center and a Land Mobile Radio (LMR) system when the dispatch center is disconnected from the LMR system, the system comprising:

• a controller configured to detect the disconnection between the dispatch center and the LMR system;
• two or more control stations coupled to the controller via an IP network, wherein at least one of the two or more control stations is configured to establish a wireless radio frequency communication link between the dispatch center and the disconnected LMR system;
• and
• wherein the controller is further configured to, in response to detecting the disconnection, allocate a first one of the two or more control stations as a control channel for the disconnected LMR system, and allocate a second one of the two or more control stations as a voice channel for communicating with the disconnected LMR system over the voice channel by transmitting and receiving voice calls between the disconnected LMR system and a console of the dispatch center via the wireless radio frequency communication link, and wherein the voice calls comprise radio transmissions of a plurality of service radios communicating wirelessly with the disconnected LMR system.
