In accordance with the preferred embodiment of the present invention all remote units ( 113-118 ) participating in a group call can actively transmit uplink communications to their respective base stations ( 101-102 ) via low-data rate traffic channels ( 103-108 ). The remote units having the highest transmit energies are summed and broadcast to all remote units ( 113-118 ) participating in the group call. Because only those remote units having the highest transmit energies are summed and broadcast, network congestion is greatly reduced.
