In a multiple RF communication system arrangement wherein a subscriber has a first identification number (ID) within a first RF communication system, and wherein the subscriber has a second ID within a second RF communication system, an arrangement (400) is provided for the subscriber to uniquely identify itself by means of a third ID to a console serving both the first and second RF communication systems.

Arrangement for identifying subscribers

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.
