Solution Overview

Problem

Existing 5G edge networks lack a mechanism to optimally manage cache data and user requests over edge nodes, as they fail to adapt to dynamic user density and association patterns, leading to inefficiencies in content caching, especially during high user request scenarios.

Innovation Solution

A method and system that dynamically manage cache data by receiving node parameters, MEC node association metrics, and data request parameters, identifying variations, and selecting the most suitable edge node based on predefined thresholds to store cache data, ensuring optimal caching even when the nearest edge node is not the best option.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If cache data is stored at the nearest edge node, then access speed is improved, but network congestion and latency increase during high user request scenarios

Engineering Contradiction:
Improveaccess speedVSAvoidbandwidth congestion
Core Design Contradiction:
SpeedVSLoss of energy

Solution Approach 1:

The system segments user requests and cache data across multiple edge nodes rather than concentrating them at a single nearest node. The orchestration module distributes cache data to different edge nodes based on user density and location affinity, dividing the load to prevent bandwidth congestion while maintaining fast access through localized caching.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system adds dimensional considerations beyond simple proximity by incorporating user density and location affinity metrics into the caching decision. Instead of only considering physical distance to the edge node, the system evaluates multiple dimensions including user distribution patterns and node capacity, selecting optimal edge nodes that balance access speed with network load distribution.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If cache data is distributed across multiple edge nodes, then bandwidth utilization is optimized, but system complexity increases

Engineering Contradiction:
Improvebandwidth utilizationVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system introduces an orchestration module as an intermediary that manages cache data distribution across edge nodes. This central coordination layer handles the complexity of selecting optimal edge nodes based on user density and location affinity, while individual edge nodes simply execute caching operations according to orchestration decisions, thereby distributing productivity benefits without proportionally increasing complexity at each node.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system dynamically changes parameters such as user density thresholds and location affinity weights to optimize cache distribution. By adjusting these parameters based on real-time network conditions and user patterns, the system adapts its caching strategy to maximize bandwidth utilization while maintaining manageable complexity through standardized decision criteria.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If edge nodes dynamically adapt to user density and location affinity, then caching efficiency is improved, but computational overhead increases

Engineering Contradiction:
Improvecaching efficiencyVSAvoidcomputational overhead
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary analysis of user density and location affinity patterns to pre-determine optimal edge nodes for cache data placement. By proactively identifying and preparing optimal caching locations before user requests arrive, the system reduces real-time computational overhead while maintaining high caching efficiency through pre-computed location affinity metrics and user density assessments.
