Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, determining whether redundant transmission is enabled for user plane apparatuses or QoS flows is unclear, with unknown parameters and decision-making entities, which affects high reliability in user plane support.
Innovation Solution
A method and apparatus that receive trigger information including prediction, load, and reliability indication information to determine if redundant transmission is enabled, with the session management or policy control apparatus making decisions based on this information to ensure QoS requirements are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant transmission is implemented to ensure high reliability, then service reliability is improved, but network resource consumption and system complexity increase
Solution Approach 1:
The patent changes the parameter of transmission redundancy by dynamically adjusting whether redundant transmission is enabled based on user plane reliability assessments. The session management function switches between single transmission and redundant transmission modes according to real-time network conditions, transforming a static configuration parameter into a dynamic one that adapts to changing reliability requirements.
Solution Approach 2:
The patent implements dynamic decision-making for redundant transmission by introducing a continuous monitoring and assessment mechanism. The session management function continuously evaluates user plane reliability indicators and dynamically adjusts the transmission strategy, transitioning from a static to a dynamic system that adapts to real-time network conditions and reliability requirements.
2Reliability
If redundant transmission is enabled for all QoS flows, then high reliability is achieved, but network resource waste increases
Solution Approach 1:
The patent applies local quality by enabling redundant transmission selectively for specific QoS flows based on their individual reliability requirements and the assessed user plane reliability. Instead of uniformly applying redundant transmission across all flows, the system tailors the redundancy level to each flow's specific needs, optimizing the balance between reliability and resource consumption.
Solution Approach 2:
The patent implements partial action by enabling redundant transmission only for certain QoS flows that require high reliability, rather than for all flows. The session management function selectively applies redundancy based on flow-specific requirements and current network conditions, avoiding the excessive resource consumption that would result from universal redundant transmission.
3Measurement precision
If multiple trigger information parameters are monitored to make accurate redundant transmission decisions, then decision accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the decision-making process by dividing trigger information into distinct categories (service level requirements, user plane reliability indicators, load conditions). Each segment is evaluated independently by the session management function, which then integrates these segmented assessments to make the final redundant transmission decision, simplifying the overall processing complexity.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of the session management function that mediates between multiple trigger information sources and the final redundant transmission decision. This intermediary consolidates and harmonizes information from various sources (QoS parameters, reliability indicators, load conditions), transforming complex multi-source data into a unified decision framework.
