Claim:
1. A method of dynamic location-based group formation for a movable incident scene in a wireless radio communication system comprising a plurality of first subscriber units, the method comprising: receiving, at a controller from one of a second subscriber unit and a dispatch console, a request for a new group call for a movable incident scene; receiving, at the controller, an initial location associated with the movable incident scene and an indication of a speed and direction of travel associated with the movable incident scene; determining, by the controller and as a function of the initial location and the indication of the speed and direction of travel associated with the movable incident scene, one or more potential future locations of the movable incident scene different from the initial location; determining, by the controller, a current location of each of the plurality of first subscriber units; identifying, by the controller, a set of one or more inclusion threshold rules for each of the one or more potential future locations, each set of inclusion threshold rules including one or more of a distance-based inclusion threshold rule and an arrival-time-based inclusion threshold rule relative to the respective potential future location; forming, by the controller, one of (i) a location-based group including first subscriber units meeting at least one inclusion threshold rule in the respective identified set of inclusion threshold rules for any one of the one or more potential future locations, wherein the one or more potential future locations includes a plurality of potential future locations, and (ii) a location-based group including first subscriber units meeting at least one inclusion threshold rule in the respective identified set of inclusion threshold rules for any one of the one or more potential future locations or meeting an inclusion threshold rule for the initial location, further identified by the controller, wherein the identified inclusion threshold rule for the initial location comprises first subscriber units having current locations that fall within a maximum response distance associated with and relative to the initial location of the movable incident scene; and causing one or more of audio and data transmitted by the one of the second subscriber unit and the dispatch console to be provided to the first subscriber units in the formed location-based group.
