Abstract: A system and method for dispatching emergency services personnel and equipment are provided. The system includes a central server, a dispatcher terminal and a plurality of mobile data terminals (MDTs) associated with the emergency services personnel and equipment. The central server processes incoming calls for emergency services and outgoing messages from the dispatcher terminal. Based upon the dispatching message for the incoming call, the central server automatically queries a plurality of databases in accordance with a predetermined set of rules for information relevant to the emergency and the dispatched personnel and equipment. Based upon the information received, the central server automatically transmits appropriate messages and warnings to the MDTs traveling to the site of the emergency and queries the databases further using further predetermined rules. Additional messages and warnings are transmitted to the MDTs based upon the further information received.
