Ethernet Header Compression for Air Interface Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication methods lack a compression method for data packets that include an Ethernet header, which hinders efficient radio resource utilization in air interface transmissions.
Innovation Solution
A communication method that compresses and decompresses data packets with Ethernet headers by identifying fields to be compressed and replacing or removing them with shorter fields, while maintaining context information for accurate decompression at the receiving end.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If data packets with Ethernet headers are transmitted without compression, then the transmission is simple and reliable, but radio transmission resources are wasted
Solution Approach 1:
The Ethernet header is divided into multiple fields (destination address, source address, length/type) that can be independently compressed. Each field is analyzed and compressed separately based on its characteristics, allowing selective compression of redundant information while maintaining necessary packet identification data.
Solution Approach 2:
Header context information is established and synchronized between sending and receiving devices before data packet transmission begins. This preliminary setup includes sharing complete header templates and field correspondence relationships, enabling the receiving device to accurately decompress packets without requiring complex real-time analysis.
2Quantity of substance
If header fields are compressed by removal or replacement, then radio resources are reduced, but the receiving device needs additional context information for accurate decompression
Solution Approach 1:
The sending device sends header context information to the receiving device, and the receiving device provides feedback to confirm successful reception and synchronization of context information. This feedback mechanism ensures both devices maintain consistent understanding of the compressed header structure, preventing information loss.
Solution Approach 2:
Header context information acts as an intermediary between the compressed data packet and the original header structure. This context information includes complete header templates and field correspondence relationships, serving as a reference that enables the receiving device to reconstruct the original header from the compressed form without losing essential information.
3Productivity
If compression is applied to Ethernet headers, then air interface resources are optimized, but the compression method must be specifically designed for Ethernet format
Solution Approach 1:
The compression method is specifically tailored to the Ethernet header structure, applying different compression strategies to different fields based on their local characteristics. For example, address fields use template-based compression while length/type fields use direct encoding, optimizing compression efficiency for each specific field type within the Ethernet header.

AI summary
A communication method and a device are described to compress and decompress a data packet including an ethernet header to reduce radio transmission resources of an air interface. The communication method includes determining, by a sending device, a to-be-sent data packet. The to-be-sent data packet is a data packet including an ethernet header. The method further includes determining, by the sending device, a field to be compressed in the header of the to-be-sent data packet; and compressing, by the sending device, the header of the to-be-sent data packet according to a preset method. The preset method includes: removing the field to be compressed from the header of the data packet, or replacing the field to be compressed with a corresponding short field; and sending, by the sending device, a data packet obtained after the compressing.
