Audio summing systems and methods in radio communication systems

摘要

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.

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