Solution Overview

Problem

Current CoMP link mechanisms do not provide optimization at an individual user device (UE) level, leading to inefficient resource management and outdated link formations, which can result in suboptimal service quality and resource utilization at cell edges.

Innovation Solution

A system and method for dynamic CoMP link maintenance that detects triggers for link maintenance, estimates throughput, calculates resource utilization metrics, and determines necessary changes to optimize CoMP links, including merging data bearer channels, scheduling data rates, and terminating inactive links to optimize physical resources, power, and X2 links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If CoMP links are established to improve network performance at cell edges, then service quality and connectivity are improved, but resource utilization efficiency deteriorates due to outdated link formations and lack of optimization

Engineering Contradiction:
Improveservice qualityVSAvoidresource utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements dynamic CoMP link maintenance by continuously monitoring link conditions and automatically adjusting link configurations. The system transitions from static, pre-configured CoMP links to dynamic links that adapt to changing network conditions, user movements, and resource availability, thereby maintaining service quality while optimizing resource utilization.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs feedback mechanisms by monitoring link throughput, resource utilization metrics, and trigger conditions. Based on this feedback, the system determines whether to maintain, modify, or terminate CoMP links, creating a closed-loop control system that optimizes resource usage while preserving service quality.

Inventive Principle:
Principle #23Feedback

2Productivity

If dynamic CoMP link maintenance is implemented to optimize resource utilization, then resource efficiency improves, but system complexity increases due to additional monitoring and decision-making processes

Engineering Contradiction:
Improveresource efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where the system automatically monitors link conditions, evaluates maintenance needs, and executes link configuration changes without external intervention. The eNodeB autonomously makes decisions about CoMP link maintenance based on predefined criteria and real-time measurements, reducing the need for complex external control systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual or centralized control mechanisms with automated algorithmic decision-making. Instead of relying on complex mechanical or procedural systems for link management, the invention uses software-based algorithms that automatically evaluate link conditions and determine maintenance actions, simplifying the overall system architecture.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If CoMP links are maintained for all user equipment, then service quality is preserved, but resource consumption increases due to inactive links and lack of termination mechanisms

Engineering Contradiction:
Improveservice qualityVSAvoidresource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements mechanisms to discard inactive or unnecessary CoMP links and recover the resources they occupy. By continuously evaluating link utility and terminating links that no longer serve active users or meet performance thresholds, the system releases radio resources, processing power, and memory for reuse, thereby reducing overall resource consumption while maintaining service quality for active users.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The patent changes the operational parameters of CoMP links dynamically based on user activity and network conditions. Links are activated or deactivated, and their configuration parameters are adjusted according to real-time measurements, ensuring that resources are allocated only when and where needed, thus reducing waste while preserving service quality.

Inventive Principle:
Principle #35Parameter changes
