Abstract: In a communication system having a communication resource allocator, a plurality of communication units, a plurality of communication resources, and at least one console, the communication resource allocator is improved to comprise system reconfiguration databases, selection information, execution information, and predetermined event receiving information. The improvement allows the communication system to be automatically reconfigured in response to a predetermined event. The predetermined event is typically initiated by one of the plurality of communication units.

Abstract: A communication resource method is set forth that allows communication with a subscriber unit that is in a priority access mode. Either a communication resource allocator or a subscriber unit is enabled to initiate a priority communication state in which a subscriber unit is accessible to reception of radio transmissions during the subscriber unit's priority mode status.

Abstract: In a communication system that comprises a plurality of communication resources, a plurality of consoles, a communication resource allocator, and a plurality of subscriber units arranged into a plurality of communication groups, the communication resource allocator comprises memory for storing presented and unpresented communication groups. By storing unpresented communication groups, a console, via an associated operator MUX interface module, may automatically utilize the unpresented communication groups without intervention from an operator of the console.
