Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network devices struggle with refined congestion control and accurate access control due to insufficient assistance information from terminals, leading to inefficient management of XR services with high delay requirements and varying quality-of-service needs.
Innovation Solution
Terminals transmit detailed assistance information, including QoE, data rates, error rates, packet delays, buffer occupancy, and congestion levels to network devices, enabling precise congestion control and access management for XR services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If terminals transmit detailed assistance information including QoE, data rates, error rates, packet delays, buffer occupancy, and congestion levels, then network control accuracy is enhanced, but device complexity increases
Solution Approach 1:
The patent segments the assistance information into multiple categories (QoE information, data rate information, error rate information, packet delay information, buffer occupancy information, congestion level information). This segmentation allows the terminal to transmit detailed information in an organized manner while enabling the network to process and utilize different types of information for specific control functions, thereby improving network control accuracy without overwhelming complexity
Solution Approach 2:
The patent implements a feedback mechanism where terminals transmit assistance information to network devices, which then adjust scheduling and resource allocation based on this feedback. The network device receives the assistance information, processes it, and modifies its control decisions accordingly. This closed-loop feedback system enables continuous improvement of network control accuracy while managing terminal complexity through structured information reporting
2Productivity
If the network device performs refined congestion control and access control based on terminal feedback, then productivity is improved, but loss of information increases
Solution Approach 1:
The patent extracts and processes only the necessary information from the assistance information transmitted by terminals. The network device selectively processes specific types of information (QoE, data rates, error rates, packet delays, buffer occupancy, congestion levels) that are relevant for congestion control and access control decisions. This extraction approach improves productivity by focusing on actionable information while reducing the loss of information through targeted processing rather than comprehensive analysis
Solution Approach 2:
The patent utilizes parameter changes in the assistance information (such as changes in packet delay, buffer occupancy, or congestion levels) to trigger network control actions. When parameters exceed threshold values or show significant changes, the network device adjusts scheduling and resource allocation accordingly. This parameter-driven approach improves productivity by enabling dynamic adaptation to changing network conditions while minimizing information processing overhead through threshold-based decision making
