Solution Overview
Problem
Radio access networks face challenges in controlling error propagation and identifying burst boundaries in bursty signaling environments, leading to increased infrastructure costs and reduced spectral efficiency due to the need for more optical or wireless links.
Innovation Solution
A method and apparatus for compressing and decompressing data bursts that limit synchronization errors to a desired number of signal samples and identify the burst boundary, using a compression module with a compressor and decompressor that generate and parse headers with start of burst and packet size parameters, allowing for dynamic or static packet sizing to reestablish synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If compression techniques are used to reduce the number of optical or wireless links, then infrastructure cost is reduced, but error propagation control and burst boundary identification become difficult
Solution Approach 1:
The patent applies preliminary action by inserting synchronization fields and packet size information at the beginning of compressed data packets before transmission. This allows the receiving end to预先 establish the framework for error detection and burst boundary identification, enabling reliable operation even with reduced infrastructure
Solution Approach 2:
The patent implements feedback mechanisms through checksum fields and synchronization indicators that provide error detection information back to the receiving end. This feedback loop enables the system to detect and correct errors without requiring additional physical links, thus reducing infrastructure cost while maintaining reliability
2Loss of energy
If compression techniques are used to reduce the number of optical or wireless links, then infrastructure cost is reduced, but the ability to identify burst boundaries deteriorates
Solution Approach 1:
The patent uses synchronization fields with specific bit patterns (analogous to color changes) that stand out in the compressed data stream. These distinctive patterns mark burst boundaries, making them easily identifiable even after compression, thus reducing the need for additional infrastructure while maintaining detection capability
Solution Approach 2:
The patent embeds packet size information and burst boundary markers at the beginning of each compressed packet before transmission. This preliminary structuring allows the receiving end to easily identify burst boundaries without requiring complex analysis or additional physical resources
3Reliability
If synchronization errors occur in compressed data packets, then error propagation affects multiple signal samples, but the ability to reestablish synchronization deteriorates
Solution Approach 1:
The patent places synchronization fields and packet size information at the beginning of each compressed packet. This preliminary structuring enables the receiving end to quickly reestablish synchronization after errors by simply reading these pre-positioned markers, reducing the complexity of error recovery mechanisms while maintaining reliability
Solution Approach 2:
The synchronization field acts as an intermediary element between the compressed data and the receiving end's error recovery process. This intermediary provides a clear reference point that simplifies the reestablishment of synchronization, reducing the complexity of the overall error recovery mechanism

AI summary
The method and apparatus of the present invention provides for the compression and decompression of data bursts wherein the propagation of synchronization errors is limited to a desired number of signal samples and the start of a burst boundary is identified. In accordance with the present invention, a method and apparatus are provided for compressing data in a communication system by receiving data bursts comprising a plurality of uncompressed data packets at a compressor of the communication system, generating a start of burst parameter and a packet size parameter for each of the uncompressed data packets and compressing the data packets. At the decompressor, the compressed data packets are received and when a synchronization error occurs, the packet size parameter is used to limit the propagation of the error to a desired number of samples and to restore the data burst utilizing the start of burst parameter.
