Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the PCRF entity formulates a data flow transmission policy only according to operator policy or user subscription data, then the policy formulation process is simple, but the user experience is poor
Solution Approach 1:
The patent implements a feedback mechanism where the PCRF entity receives transmission quality information about downlink data flows and uses this feedback to dynamically adjust quality of service policies. This closes the loop between actual network performance and policy formulation, allowing the system to adapt policies based on real-world conditions rather than relying solely on static operator policies or subscription data.
Solution Approach 2:
The patent transforms the static policy formulation process into a dynamic one by continuously monitoring transmission quality metrics and adjusting quality of service policies in real-time. The system transitions from fixed policies based on pre-configured data to adaptive policies that respond to changing network conditions and actual user experience.
2Device complexity
If the PCRF entity uses only operator policy and user subscription data for policy formulation, then the system complexity is low, but the transmission quality adjustment capability is insufficient
Solution Approach 1:
The PCRF entity receives feedback regarding actual transmission quality of downlink data flows and uses this information to precisely adjust quality of service policies. This feedback loop enables the system to achieve accurate transmission quality control by continuously comparing actual performance against target quality levels and making appropriate policy adjustments.
Solution Approach 2:
The patent replaces manual or static policy configuration mechanisms with an automated system that uses transmission quality measurements to dynamically determine appropriate quality of service policies. The system substitutes mechanical/manual policy setting with an intelligent feedback-driven approach that automatically adjusts policies based on measured network conditions.
