QoS Switching via Aggregate Resource Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods in mobile communication systems lack a systematic process for Quality of Service (QoS) switching that adapts to dynamic resource allocation and availability, leading to excessive QoS switching and inefficient resource usage.
Innovation Solution
A QoS switching method and apparatus that periodically compares total resource usage to predefined thresholds, determining QoS switching by adjusting the levels of multiple QoSs through downgrade, upgrade, or grade maintenance, based on average resource usage per user to adapt to dynamic resource availability.

Engineering Contradiction Analysis
1Reliability
If conventional methods apply QoS switching individually per user or per QoS type, then QoS requirements can be addressed, but excessive QoS switching occurs and resource usage dynamic range increases
Solution Approach 1:
The patent combines multiple individual QoS switching decisions into a single aggregate QoS switching decision by comparing total resource usage across all users against a threshold. This merging approach prevents excessive individual switching events while still addressing QoS requirements collectively, thereby improving system efficiency without completely sacrificing individual QoS satisfaction.
Solution Approach 2:
The patent changes the parameter for QoS switching from individual user/QoS-level resource usage to aggregate total resource usage. By monitoring the sum of resource usage across all users rather than individual user resource usage, the system reduces switching frequency while maintaining overall QoS performance through threshold-based aggregate control.
2Adaptability or versatility
If QoS switching is performed frequently to adapt to dynamic resource availability, then QoS can be optimized, but excessive switching occurs leading to system instability
Solution Approach 1:
The patent implements periodic QoS switching by comparing total resource usage against a threshold at regular intervals rather than continuously or on every resource change event. This periodic approach allows the system to adapt to dynamic resource availability while filtering out transient fluctuations that would cause excessive switching, thereby maintaining stability.
Solution Approach 2:
The patent uses threshold-based feedback control where the aggregate QoS level is adjusted based on whether total resource usage exceeds or falls below predefined thresholds. This feedback mechanism provides stable, rule-based adaptation to dynamic resources, preventing oscillatory behavior and excessive switching by only triggering changes when significant threshold crossings occur.
3Productivity
If aggregate total resource usage is monitored and compared to threshold, then excessive QoS switching is prevented, but individual QoS requirements may be less precisely addressed
Solution Approach 1:
The patent segments the aggregate QoS management into two levels: aggregate level for switching decisions (comparing total resource usage to threshold) and individual level for resource allocation (distributing available resources among users). This segmentation allows efficient aggregate control to prevent excessive switching while still maintaining individual QoS considerations through the allocation process.
