Solution Overview
Problem
Current wireless communication networks face challenges in efficiently compressing Ethernet headers for data packets transmitted over the control plane, leading to increased data transfer latency and inefficiencies in 5G networks.

Implementing Ethernet Header Compression (EHC) by allowing user equipment (UE) to negotiate with network components for EHC support, enabling the compression of Ethernet headers within control plane data packets, thereby reducing data transfer latency and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If Ethernet headers are transmitted uncompressed in control plane data packets, then data transmission reliability is maintained, but data transfer latency increases and transmission efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by establishing EHC context and negotiating compression parameters before actual data transmission begins. The UE and network component perform capability exchange and context setup in advance, so that when data packets are transmitted, the compression algorithms are already configured and ready, eliminating setup delays during data transfer and reducing overall latency
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting compression parameters based on traffic conditions and packet types. The system modifies compression depth, algorithm selection, and context parameters adaptively, allowing optimal compression ratios for different data scenarios while maintaining low computational overhead, thus reducing latency without excessive complexity
2Productivity
If Ethernet headers are compressed using EHC for control plane data, then data transmission efficiency improves, but protocol complexity and negotiation overhead increase
Solution Approach 1:
The patent applies the extraction principle by separating EHC capability negotiation and context management into distinct phases from the main data transmission flow. The capability exchange and context setup are extracted as preliminary steps, allowing the core data transmission to focus solely on compressed packet handling, thereby improving transmission efficiency while confining protocol complexity to specific management functions
Solution Approach 2:
The patent applies universality by designing the EHC mechanism to handle multiple Ethernet packet types and control plane protocols through a unified compression framework. The same EHC context and algorithms serve various data scenarios, reducing the need for separate negotiation procedures for each packet type and minimizing overall protocol complexity
3Quantity of substance
If EHC is implemented for control plane data transfer, then bandwidth utilization improves, but processing overhead at network components increases
Solution Approach 1:
The patent applies self-service by implementing compression at the UE side before transmission, shifting the primary processing burden from network components to the endpoint device. The UE performs header compression locally using stored context, so that network components receive already-compressed packets requiring minimal processing, thereby improving bandwidth utilization while keeping network processing overhead low

AI summary
Enabling Ethernet Header Compression (EHC) for use with data sent within a Non-Access Stratum (NAS) control plane of a wireless communication network. In one aspect, a wireless communication device sends a signal to a wireless communication network indicating the device supports EHC for data transfer over a control plane. The device obtains a response from the wireless communication network indicating the wireless communication network supports EHC for data transfer over the control plane. The device then sends an Ethernet packet compressed using EHC to the wireless communication network over the control plane. The wireless communication device may be configured to send a request to the wireless communication network to use EHC before sending the Ethernet packet compressed using EHC. The device sends the compressed Ethernet packet only if the request is granted. In another aspects, complementary EHC features are provided within a network component of the wireless communication network.
