Solution Overview

Problem

Network congestion during peak usage times or in low-capacity areas leads to slower data speeds, dropped calls, and unreliable network connections, particularly in low-bandwidth environments, impacting user experience and network stability.

Innovation Solution

Implementing a constrained data mode on user equipment (UE) by detecting network congestion using AI/ML techniques and providing an indication to UE to adjust communication services, such as limiting data usage to SMS or lower quality of service, to alleviate congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If network capacity is increased to handle more users during peak times, then network coverage and connectivity are improved, but network congestion and bandwidth exhaustion worsen

Engineering Contradiction:

Improvenetwork connectivityVSAvoidnetwork traffic volume

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements dynamic data modes that automatically adjust network resource allocation based on real-time congestion conditions. The system transitions between unconstrained and constrained data modes, modifying data transmission parameters dynamically to adapt to varying network load, thereby maintaining connectivity while managing traffic volume during peak usage periods

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes key operational parameters including data mode constraints, QoS policies, and transmission priorities based on detected congestion levels. By modifying these parameters, the network can handle varying traffic volumes while maintaining acceptable service quality and preventing complete bandwidth exhaustion

Inventive Principle:

Principle #35Parameter changes

2Productivity

If data transmission speed is increased, then user experience and productivity are improved, but network congestion and signal interference worsen

Engineering Contradiction:

Improvedata transmission speedVSAvoidsignal interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies partial action by implementing constrained data modes that limit data transmission to essential services only during congestion periods. Non-critical data traffic is restricted or delayed, allowing critical communications to maintain adequate speeds while reducing overall signal interference and network load

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system continuously monitors network congestion indicators, signal quality metrics, and transmission success rates. Based on this feedback, it automatically adjusts data transmission parameters and mode constraints, reducing speeds when interference is detected and恢复正常 speeds when conditions improve, thereby balancing productivity with interference management

Inventive Principle:

Principle #23Feedback

3Reliability

If network bandwidth is allocated to high-priority services, then service quality is improved, but available bandwidth for other services is reduced

Engineering Contradiction:

Improveservice qualityVSAvoidservice flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments network services into different priority categories (critical, essential, non-essential) and applies differentiated data modes to each segment. Critical services receive guaranteed bandwidth and unconstrained access, while non-essential services are subject to constraints during congestion, thereby ensuring service quality for priorities while maintaining flexibility for lower-priority traffic

Inventive Principle:

Principle #1Segmentation

4Stability of the object's composition

If congestion control mechanisms are implemented, then network stability is improved, but data transmission efficiency and user experience worsen

Engineering Contradiction:

Improvenetwork stabilityVSAvoiddata transmission efficiency

Core Design Contradiction:

Stability of the object's compositionVSProductivity

Solution Approach 1:

The system implements periodic assessment of congestion conditions and alternating between constrained and unconstrained data modes based on real-time network state. During stable low-congestion periods, full efficiency is restored; during high-congestion periods, constraints are applied. This periodic adaptation maintains network stability while minimizing the impact on overall transmission efficiency

Inventive Principle:

Principle #19Periodic action
