Airborne e-mail data transfer protocol
First Claim
1. An improved data retrieval and transmission system for use aboard an aircraft comprising an airborne server connected to at least one passenger'"'"'s computing device, and ground based server, and a means for exchanging data between the airborne server and the ground based server, the improvement comprising:
- means on the ground based server for converting data to be transferred between the airborne server and the ground based server to a plurality of sequenced frames, where the ground based server maintains a delivery status of each frame in the sequence;
where the ground based server, upon interruption of the means for exchanging data during transmission of a sequence of frames, transmits only frames having a status of not already having been delivered.

Abstract
An e-mail delivery and transmission system has been developed for an aircraft environment to meet the special needs of the aircraft passenger. Due to the tenuous and expensive nature of the communications link between an aircraft and a ground based e-mail computer server, the system has streamlined the data exchange to provide only the information desired by the passenger, reducing costs and providing a more efficient system. The streamlining includes sequencing frames of data and tracking the delivery status of these frames, such that if there is an interruption of the communication link during the transmission of data, only unsent frames are delivered upon reconnection. Other features include call initiation options for contacting the ground server from the aircraft, and statistics gathering functions for providing the passenger with accrued costs, data transmission, and call time. The system permits the tracking of messages using an assigned identifier for each data package, and data compression is employed to reduce transmission costs.

7. The improved data retrieval and transmission system of claim 1 wherein data exchanged between the airborne server and the ground based server is encrypted prior to said exchange.
-
8. The improved data retrieval and transmission system of claim 1 wherein data exchanged between the airborne server and the ground based server is compressed prior to said exchange.
-
9. The improved data retrieval and transmission system of claim 1 further comprising a mail manager for maintaining statistics of the amount of data exchanged for each passenger.
-
10. The improved data retrieval and transmission system of claim 1 wherein the system maintains statistics on the time of each call attributed to each passenger.
-
11. The improved data retrieval and transmission system of claim 1 wherein a passenger can request a status of a particular message file sent by the passenger to the ground based server.
-
12. The improved data retrieval and transmission system of claim 1 wherein the passenger may assign a priority to an outgoing message file to be delivered from the airborne server to the ground based server.
-
13. The improved data retrieval and transmission system of claim 1 wherein the passenger may assign a priority to an incoming message file to be delivered from the ground based server to the airborne server.
-
14. The improved data retrieval and transmission system of claim 1 wherein the system maintains information about each data file sent by a passenger, said information comprising sender, recipient, size, and time sent.
-
15. An improved data retrieval and transmission system for use aboard an aircraft comprising an airborne server connected to at least one passenger'"'"'s computing device, and ground based server, and a means for exchanging data between the airborne server and the ground based server, the improvement comprising:
call initiating means for initiating a call between the airborne server and the ground based server while the aircraft is in flight, wherein the call initiating means is an automated function of the airborne server predetermined to initiate a call upon the existence of one or more predetermined criteria, and further wherein one of the predetermined criteria is the queuing of outgoing data. - View Dependent Claims (16, 17)
