Abstract: A method, a device, and a communication system include receiving one or more concurrent transmissions from one or more source devices in the communication system; responsive to the one or more concurrent transmissions comprising a single source transmission from a single source device, retransmitting the single source transmission either clear or encrypted based on the single source transmission; responsive to the one or more concurrent transmissions comprising multiple transmissions from multiple source devices, performing one of: summing audio to create a summed resultant stream and broadcasting the summed resultant stream based on matching encryption parameters associated with each of the multiple transmissions; and broadcasting only a selected transmission of the one or more concurrent transmissions from a higher priority source device based on an encryption parameter mismatch between the multiple transmissions, wherein the selected transmission is broadcast based on encryption parameters associated with the selected transmission.

Abstract: A first group auditory data stream, from a transmitting subscriber device of a first group of subscriber devices or from a dispatch console and intended for the first group of subscriber devices, is received at a conference server. A second group auditory data stream from a transmitting subscriber device of a second group of subscriber devices is similarly received. The conference server determines a relative priority level of one of (i) the first group of subscriber devices relative to the second group of subscriber devices and (ii) the first group auditory data stream relative to the second group auditory data stream, and sets different relative signal gains of the first group auditory data stream and the second group auditory data stream as a function of the determined relative priority level. The two auditory data streams are then summed and forwarded towards the second group of subscriber devices.

Abstract: A first group auditory data stream, from a transmitting subscriber device of a first group of subscriber devices or from a dispatch console and intended for the first group of subscriber devices, is received at a conference server. The conference server determines whether the first group auditory data stream generated for the first group of subscriber devices is of interest to a second group of subscriber devices, and if so, sums the first group auditory data stream with a second group auditory data stream intended for the second group of subscriber devices to form a summed group auditory data stream. The conference server then forwards the summed group auditory data stream towards the second group of subscriber devices and forwards the first group auditory data stream towards the first group of subscriber devices.
