Network Resource Reallocation Controller for Dynamic QoS Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network resource allocation in LTE telecommunication systems results in static allocations that do not efficiently utilize available resources, leading to a decrease in Quality of Experience (QoE) due to inflexibility and neglect of UE-originated events indicating changes in Quality of Service (QoS) requirements.
Innovation Solution
A system where measured QoE-related information elements are translated into dynamic resource reallocation requests, allowing a network node to adjust resources based on live data from User Equipment (UE), incorporating an information collection module and a resource reallocation request generator to prioritize applications and reallocate network resources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static network resource allocation is used, then device complexity is reduced and ease of operation is improved, but resource utilization efficiency deteriorates and Quality of Experience decreases
Solution Approach 1:
The patent implements dynamic network resource allocation by translating measured QoE-related information elements into resource reallocation requests. The network node continuously monitors QoE metrics from UE applications and adjusts resource allocation in real-time based on changing QoS requirements, transforming the static allocation system into a dynamic one that adapts to actual network conditions and user needs.
Solution Approach 2:
The system establishes a feedback loop where QoE-related information elements measured from UE applications are continuously translated into resource reallocation requests. This feedback mechanism allows the network node to monitor application performance and automatically adjust resource allocation based on actual QoS requirements, improving resource utilization while maintaining system manageability through automated control.
2Stability of the object's composition
If static network resource allocation is used, then system stability is improved, but adaptability to changing QoS requirements deteriorates
Solution Approach 1:
The patent enables the network resource allocation system to transition from static to dynamic operation by continuously translating QoE-related information elements into reallocation requests. This allows the system to maintain stability through controlled, incremental adjustments while adapting to changing QoS requirements as they arise from UE application performance variations.
Solution Approach 2:
The feedback mechanism translates measured QoE information into resource reallocation requests, creating a closed-loop control system. This allows the network to detect changes in application QoS requirements and automatically adjust resource allocation accordingly, maintaining system stability through gradual adaptation rather than abrupt changes.
3Reliability
If QoE-related information is collected and used for resource reallocation, then Quality of Experience is improved, but device complexity and processing overhead increase
Solution Approach 1:
The network resource reallocation controller automatically translates measured QoE-related information elements into resource reallocation requests without requiring manual intervention. The system self-manages the complex task of monitoring QoE metrics, interpreting application performance data, and generating appropriate resource allocation adjustments, thereby improving QoE while containing complexity within the automated control function.
Solution Approach 2:
The patent introduces a network resource reallocation controller as an intermediary component that bridges QoE measurement and resource allocation. This intermediary translates QoE-related information elements into standardized resource reallocation requests, managing the complexity of QoS optimization while presenting a simplified interface to both the measurement system and the network resource management functions.
