Method and apparatus for adaptive control of forward error correction codes
First Claim
1. In an interconnect apparatus disposed between a terrestrial cell and/or packet switch at a first terminal and one or both of a satellite and wireless network connecting to a second terminal, a method for the adaptive control of a forward error correction code for transmission over a communication channel which connects said first terminal to said second terminal, said method comprising the steps of:
- calculating a byte error rate associated with communication signals received by said first terminal via said communication channel from said second terminal;
determining a forward error correction code length of said forward error correction code based on said byte error rate, said forward error correction code length being varied in accordance with said byte error rate;
transmitting said forward error correction code length to said second terminal over said communication channel; and
changing the forward error correction code at said first and second terminals in a synchronized manner without data loss.

Abstract
A method for adaptive control of a forward error correction code for transmission between a terrestrial cell/packet switch at a first terminal and a satellite/wireless network connecting to a second terminal, including the steps of: calculating a byte error rate associated with communication signals received by the first terminal, determining a forward error correction code length based on the byte error rate, and transmitting the forward error correction code length to the second terminal.

14. In an interconnection apparatus at a first terminal disposed between a cell and/or packet switch and one or both of a satellite and wireless communication network, an apparatus for the adaptive control of a forward error correction code for transmission over a communication channel which connects said first terminal to a second terminal, said apparatus comprising:
-
means for calculating a byte error rate associated with communication signals received by the first terminal via said communication channel from said second terminal;
means for determining a forward error correction code length of said forward error correction code based on said byte error rate, said forward error correction code length being varied in accordance with said byte error rate; and
means for transmitting said forward error correction code length to the second terminal over said communication channel;
wherebythe forward error correction code at said first and second terminals may be changed in a synchronized manner without loss of data. - View Dependent Claims (15, 16, 17, 18, 19, 20)
