A communication system (100) has automatic selection of talkgroups based on geographically defined areas. The system (100)includes wireless two-way communication units (120) capable of communicating with each other within a coverage area 205. A particular communication unit 120 is automatically caused to operate as a member of a particular talkgroup when that particular communication unit (120) is within a particular area of operation (207), which particular area of operation (207) is smaller than, and contained within, the coverage area (205).

Method and apparatus for automatically selecting a radio talkgroup

A method is disclosed, and an apparatus described, for providing a console display indicating the incompatibility of a subscriber with a talk group in an RF communication system. The console provides a first display as long as the system detects no subscriber incompatibility with a talk group. When the system determines the subscriber is incompatible with a talk group, however, the console provides a second display which is graphically distinct from the first display. The second display is further arranged so the incompatible subscriber can readily be identified.
