Abstract: A packetized voice communication method and system. Techniques are disclosed for supporting communication between aircraft and ground stations using packetized digitally-encoded messages. The encoded messages, which originate from verbalized messages, may be transmitted using conventional and future radio frequency (RF) radio communication technologies. Virtual channels are employed to enable a single ground station or controller to communicate with multiple aircraft by employing different physical radio transmission channels for the aircraft. Messages sent from aircraft to controllers are received by various ground antennas and routed to an appropriate ground station identified by each message's packet header. The messages for a given ground station are inserted into a queue that is manually or automatically advanced. Upon reaching the top of the queue, the message is decoded and played back at the controller's headset. Controller-to-aircraft messages are sent in a similar manner.
