Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deployment of multiple radio access technologies (RATs) in wireless networks leads to network overload and underutilization of resources, resulting in slower services and resource waste, as newer RATs are deployed over time, causing imbalances in network load and capacity.
Innovation Solution
A system and method for dynamically modifying buffer sizes based on network load conditions, using a network load monitoring processor to measure and compare load values with predetermined thresholds, triggering buffer size adjustments to initiate carrier aggregation and balance network load across different RATs, such as NR and LTE.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If newer RAT technologies are deployed to provide additional resources and faster communications speeds, then network capacity and service quality are improved, but network overload occurs and service interruptions result
Solution Approach 1:
The patent implements dynamic buffer size adjustment for different RAT types based on real-time network load conditions. The buffer management processor continuously monitors network load and modifies buffer sizes dynamically, transitioning from static to adaptive resource allocation. This allows the system to handle varying traffic demands and prevent network overload while maintaining service continuity.
Solution Approach 2:
The patent changes the buffer size parameter for different RAT types (e.g., NR and LTE) based on measured network load values. When network load exceeds predetermined thresholds, the system adjusts buffer sizes to redistribute traffic, thereby preventing network overload and maintaining reliable service delivery across multiple RATs.
2Adaptability or versatility
If multiple RATs are deployed simultaneously to increase network coverage and resources, then network capability is enhanced, but resource utilization becomes unbalanced with under-utilized pre-existing RAT resources
Solution Approach 1:
The patent implements a feedback mechanism where the buffer management processor continuously monitors network load on different RATs and adjusts buffer sizes accordingly. This closed-loop control ensures that resources are dynamically reallocated based on actual usage patterns, preventing both overload and underutilization, thereby improving overall resource utilization efficiency while maintaining enhanced network coverage.
Solution Approach 2:
The system automatically monitors network load and performs self-adjustment of buffer sizes without external intervention. The buffer management processor autonomously detects load imbalances and reallocates resources by modifying buffer parameters, enabling the network to self-optimize resource utilization across multiple RATs while maintaining versatile coverage.
3Reliability
If buffer sizes are increased to handle network load, then service quality is maintained, but network resources are wasted when load is low
Solution Approach 1:
The patent transitions from static buffer allocation to dynamic buffer size adjustment. The buffer management processor continuously adapts buffer sizes based on real-time network load measurements, ensuring that sufficient buffer resources are allocated during high load to maintain service quality, while reducing buffer allocation during low load periods to prevent resource waste.
4Device complexity
If fixed buffer sizes are used for different RATs, then system complexity is reduced, but resource utilization efficiency deteriorates under varying network conditions
Solution Approach 1:
The patent introduces dynamic parameter adjustment (buffer size) based on network load conditions. The buffer management processor modifies buffer size parameters for different RATs according to measured load values, enabling efficient resource utilization under varying network conditions while maintaining manageable system complexity through rule-based adjustment logic.
Data Source
AI summary
A system for dynamically modifying a buffer in a network deploying multiple carriers is provided. Each carrier operating over the network utilizes a radio access technology (RAT). The system includes a network load monitoring processor that measures a network load on carriers using a first RAT to produce a measured value and a buffer management processor that receives the measured value, performs a comparison of the measured value with a predetermined value, and dynamically modifies a size of the buffer when the measured value exceeds the predetermined value.
