1. A method comprising the steps of:
- providing a plurality of wireless two-way communication units capable of communicating with one another within a first geographic area of operation; and
automatically causing a particular member of the plurality of wireless two-way communication units to operate as a member of a particular talkgroup when that particular member is within a particular second geographic area of operation identified by specific geographic parameters, which second geographic area of operation is smaller than, and contained within, the first geographic area of operation.

Abstract
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).

14. In a radio communication system, a method for automatically selecting a radio talkgroup, the method comprising the steps of:
-
providing a plurality of wireless two-way communication units capable of communicating with one another within a first geographically defined area of operation; defining a second geographically defined area of operation, which second geographically defined area of operation is smaller than and contained within the first geographically defined area of operation; providing talkgroup identification information that corresponds to the second geographically defined area of operation; determining present locations of the plurality of wireless two-way communication units; and when one of the plurality of wireless two-way communication units is within the second geographically defined area of operation, automatically causing the one communication unit to operate using the talkgroup identification information that corresponds to the second geographically defined area of operation. - View Dependent Claims (15, 16, 17, 18)

19. A radio communication system having automatic selection of radio talkgroup, comprising:
-
a database having associations of talkgroup and geographically defined subregions, including an association of a particular talkgroup and a particular geographically defined subregion; and a communication unit having a receiver for receiving a signal indicating a present location of the communication unit; wherein the communication unit is responsive to the signal received by the receiver, indicating a present location of the communication unit, to initiate automatic selection of the particular talkgroup when the present location corresponds to the particular geographically defined subregion. - View Dependent Claims (20, 21)
