1. A method for transmitting a call, the method comprising:
- receiving a call at a controller located on an aircraft from an originator at a local terminal located on the aircraft, the call being directed to a ground station;
determining whether sufficient communication bandwidth is available for transmitting the call to the ground station;
providing an option to the originator of the call of recording a message when sufficient communication bandwidth is not available for transmitting the call;
storing the recorded message in a memory device located on the aircraft;
combining the recorded message with at least one other stored message into a message file in the memory device located on the aircraft; and
transmitting the message file to the ground station when sufficient bandwidth becomes available for transmitting the message file.

Abstract
An air-to-ground telecommunications system allows callers to store messages on an aircraft data server when sufficient air-to-ground communication bandwidth is unavailable for transmitting a call. The system allows aircraft callers to leave voice, fax, e-mail or other data messages. The messages are stored on the aircraft until sufficient bandwidth becomes available for transmission to the ground. Transmitting messages requires shorter air time and more efficient bandwidth usage because messages do not require a high degree of interaction between parties. The messages can also be compressed before transmission for further efficiently using aircraft-to-ground bandwidth.

4. The method of claim 1, wherein the message is one of a voice message, a data message, a fax message and an e-mail message.
-
5. The method of claim 4, wherein the message is delivered to one of an intended recipient of the message and an answering service.
-
6. The method of claim 1, further comprising:
multiplexing the message file with other aircraft data service applications.
-
7. The method of claim 1, further comprising:
a ground-based server parsing the message file into the multiple messages and delivering the multiple messages to their intended destination.
-
8. The method of claim 1, further comprising:
providing delivery status information about at least one of the multiple messages to an originator on the aircraft of the at least one of the multiple messages.
-
9. The method of claim 1 further comprising;
compressing the message and encrypting the message before transmitting the message to the ground station.
-
10. A communications system, comprising:
-
a plurality of local terminal units located on an aircraft;
a transmitter located on the aircraft transmitting calls to a ground station;
a control unit located on the aircraft and coupled to the local terminal units, the control unit receiving a call from an originator at one of the plurality of local terminal units and determining whether communication bandwidth is available for transmitting the call from the transmitter, wherein the control unit provides an option to the originator of the call for storing a message when transmitter communication bandwidth is unavailable;
a memory device, located on the aircraft and coupled to the control unit, storing the message when transmitter communication bandwidth is unavailable; and
the control unit combining the message with at least one other stored message into a message file in the memory device and the control unit cooperating with the transmitter to transmit the message file to the ground station when sufficient bandwidth becomes available for transmitting the message file. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

16. The system of claim 10, further comprising:
a ground-based server communicating with the transmitter to receive the message file and parsing the message file into the multiple messages and delivering the multiple messages to their intended destination.
-
17. The system of claim 16, further comprising:
the ground-based server providing delivery status information about at least one of the multiple messages to an originator on the aircraft of the at least one of the multiple messages.
-
18. The system of claim 10 further comprising:
the control unit compressing the message and encrypting the message before transmitting the message to the ground station.
