Abstract: In a communication system, a communication unit may access increased information in the following manner. The communication unit transmits an information access request to the communication resource allocator of the communication system, wherein the information access request comprises a selection of pre-established information for that communication unit. Upon receiving the information access request, the communication resource allocator retrieves pre-established information based upon the request and transmits it to the communication unit. The communication unit temporarily stores the pre-established information and executes a system service based upon the retrieved pre-established information.

Abstract: A computer aided dispatch system is provided for use in a trunked communication system. The system comprises at least a master file node and a plurality of user nodes. The master file node contains a data record for each subscriber on the trunked communication system. Each data record has a plurality of fields that may assume various values. Each dispatcher "attaches" to a particular value of at least one field in any of the data records. The master file node maintains the records for each subscriber and automatically transmits an updated record to each dispatcher attached to the subgroup in which the subscriber operates. In this way, dispatchers are continuously provided the latest subscriber status even though the responsibility for monitoring the status of a particular subscriber unit may dynamically pass from dispatcher to dispatcher.

Abstract: A console interface for a trunked communication system is disclosed wherein unique interface modules are coupled to the central controller and console network to establish communication therebetween. A console interface constructed and arranged to transceive trunking channel call information couples the dispatcher console to the console network thereby allowing the dispatcher to interact with the trunked system.
