Robust, inferentially synchronized transmission of compressed transport-layer-protocol headers
First Claim
1. A method for efficient transmission of TCP/IP headers via a wireless communications link from a sender to a receiver, the method comprising:
- obtaining TCP/IP packets having associated TCP/IP headers;
losslessly compressing the associated headers;
feedback-independently transmitting of a plurality of the compressed headers via the communications link;
the transmitting comprising;
adjusting a sliding window within which the plurality of the compressed headers are transmitted, wherein the adjusting is modeled to react to TCP/IP window-size changes that results from the congestion procedures of TCP/IP;
using the sliding window, W-LSB encoding the plurality of the compressed headers;
sending the resulting W-LSB encoded plurality of compressed headers.

Abstract
An implementation of a technology, described herein, for transmitting compressed network transport-layer-protocol headers in a speedy, efficient, inferentially synchronized, and robust manner. An implementation, described herein, models the transmission of compressed headers to the congestion procedure of the network transport-layer protocol (e.g., TCP'"'"'s). Doing so, the sender of the compressed headers can infer whether the receiver correctly received them. Unlike the slow direct synchronization employed by conventional schemes, this implementation of the present claimed invention inferentially synchronizes by modeling after the congestion procedure of the network transport-layer protocol. This is inherently faster than direct synchronization. Since the implementation performs well over both noiseless and noisy links, it is particularly suited to use over wireless communications channels. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
