ENHANCED DATA LINK COMMUNICATION OVER IRIDIUM
First Claim
1. A method to reduce latency in a data link communication, the method comprising:
- compressing a data packet to be uplinked from a ground station to an aircraft communications addressing and reporting system (ACARS) in an aircraft, the aircraft communications addressing and reporting system configured to receive packets having a packet size less than or equal to a first threshold packet size;
determining a packet size of the compressed data packet;
implementing an Iridium router based unrestricted digital inter-working connectivity solution data service to uplink the compressed data packet if the packet size exceeds a second threshold packet size; and
implementing a short burst data service to uplink the compressed data packet if the packet size is less than or equal to the second threshold packet size.

Abstract
A method to reduce latency in a data link communication is provided. The method includes compressing a data packet to be uplinked from a ground station to an aircraft communications addressing and reporting system (ACARS) in an aircraft and determining a packet size of the data packet. The aircraft communications addressing and reporting system is configured to receive packets having a packet size less than or equal to a first threshold packet size. An Iridium router based unrestricted digital inter-working connectivity solution data service is implemented to uplink the compressed data packet if the packet size exceeds a second threshold packet size. A short burst data service is implemented to uplink the compressed data packet if the packet size is less than or equal to the second threshold packet size.

6. A system to enhance data link communication, the system comprising:
-
an aircraft communications addressing and reporting system (ACARS) onboard an aircraft, the aircraft communications addressing and reporting system configured to receive packets having a packet size less than or equal to a first threshold packet size; an Iridium satellite transceiver onboard the aircraft, the Iridium satellite transceiver communicatively coupled to the aircraft communications addressing and reporting system and configured to implement one of an Iridium router based unrestricted digital inter-working connectivity solution data service (RUDICS) or a short burst data (SBD) service, the implementation being based on a packet size of transceived data packets, the Iridium satellite transceiver including a processor to execute software to; decompress an uplinked data packet; and if the decompressed uplinked data packet has a packet size greater than the first threshold packet size, multi-block the decompressed uplinked data packet into a plurality of blocks, each block having less than the first threshold packet size, wherein the Iridium satellite transceiver sequentially sends the plurality of blocks to the aircraft communications addressing and reporting system. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)
