Solution Overview

Problem

Existing wireless communication systems fail to timely update congestion status information during handovers between Radio Access Networks (RANs), leading to inefficiencies in throughput due to outdated congestion reporting.

Innovation Solution

Implementing a method for a communication device to manage congestion reporting using timers and conditions to accurately indicate congestion transitions, employing real and dummy data packets to ensure timely updates of congestion status, even when RANs change.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If congestion status information is not updated during handover, then device complexity is reduced, but reliability of congestion reporting deteriorates

Engineering Contradiction:

Improvecongestion management complexityVSAvoidcongestion status accuracy

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent applies preliminary action by having the source RAN send congestion status information to the target RAN before the handover is completed. This ensures that the target RAN already has up-to-date congestion information when the terminal switches, eliminating the need for complex post-handover updates while maintaining high reliability of congestion reporting.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If congestion information is continuously reported, then reliability of throughput optimization is improved, but loss of time due to processing overhead increases

Engineering Contradiction:

Improvethroughput optimization accuracyVSAvoidcongestion reporting delay

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements periodic action by having the RAN send congestion status information at specific intervals or at key events such as handover completion, rather than continuously reporting. This reduces processing overhead and time delays while still providing timely congestion information for throughput optimization when it is most needed.

Inventive Principle:

Principle #19Periodic action

3Device complexity

If congestion status is not transferred during handover, then device complexity is reduced, but loss of information about congestion status increases

Engineering Contradiction:

Improvehandover management complexityVSAvoidcongestion status information

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The patent applies preliminary action by pre-transferring congestion status information from the source RAN to the target RAN before handover completion. This ensures seamless information continuity during handover without requiring complex post-handover synchronization mechanisms, thus preventing information loss while keeping handover management simple.

Inventive Principle:

Principle #10Preliminary action
