METHOD AND APPARATUS FOR DYNAMIC LOCATION-BASED GROUP FORMATION USING VARIABLE DISTANCE PARAMETERS

摘要

Dynamic group formation in a wireless radio communication system including a plurality of subscriber units is implemented using variable distance parameters. First, a request for a new group call relative to a defined location is received at a controller from a requesting device. A current location of each of a plurality of potential responding second subscriber units is determined. A maximum response distance associated with each of the second subscriber units is determined as a function of a stored mode of transport associated with each of the second subscriber units. A group is formed including second subscriber units having current locations that fall within the maximum response distance relative to the defined location associated with that second subscriber unit. Audio or data transmitted by the requesting device is then caused to be provided to the second subscriber units in the formed group.
