Application Data Unit QoS Control for Key Frame Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G network systems struggle to accurately prioritize and transmit key data frames, such as I frames, due to the inability to parse data at the application layer, leading to potential loss and degradation of service quality in data transmission.
Innovation Solution
A transmission method that identifies and controls data at the application data unit level by providing identification and control parameters for application data units, allowing for differentiated Quality of Service (QoS) guarantees and accurate prioritization of key data frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data transmission is controlled at the network layer without application layer parsing, then device complexity is reduced, but manufacturing precision of data prioritization deteriorates
Solution Approach 1:
The patent segments data units into application layer data units with identification information, allowing selective prioritization of key data (such as I-frames) without requiring full application layer parsing. This enables precision data control at the network layer by marking important data units with identifiers that can be recognized and prioritized by network elements.
Solution Approach 2:
The patent applies preliminary action by adding identification information to application data units before they enter the network transmission system. This pre-marking of key data units (such as video I-frames with high importance identifiers) allows network elements to perform accurate prioritization without complex real-time parsing, resolving the contradiction between simplicity and precision.
2Manufacturing precision
If application layer parsing is implemented for accurate data prioritization, then manufacturing precision of data transmission is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism where identification information acts as a mediator between application layer data and network layer processing. Instead of requiring network elements to parse application layer protocols directly, the identification information serves as a simplified intermediary marker that enables accurate data prioritization through simple comparison and matching operations.
3Device complexity
If key data frames are not prioritized, then device complexity is reduced, but reliability of data transmission deteriorates
Solution Approach 1:
The patent applies local quality by differentiating transmission priorities for different types of data units within the same data stream. Key data units (such as I-frames in video streams) are marked with high-priority identification information and receive preferential treatment in terms of resource allocation, buffering, and forwarding, while non-critical data units use standard transmission paths.
