Solution Overview

Problem

Mobile telecommunications devices experience service degradation due to high traffic or equipment failures, leading to connection delays, which existing technologies fail to effectively mitigate by redirecting network traffic to alternative access methods.

Innovation Solution

A system that determines connection delays and service degradation levels in a network, using metrics to instruct user equipment to switch to alternative access methods if degradation exceeds a predetermined threshold, thereby ensuring optimal network access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If network traffic is directed to a selected access method, then connection speed is improved, but service degradation occurs due to high traffic or equipment failures

Engineering Contradiction:

Improveconnection speedVSAvoidservice degradation

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The system dynamically monitors connection delays for multiple access methods and adapts routing decisions in real-time based on current network conditions. When service degradation is detected in one access method, the system automatically redirects traffic to alternative methods, ensuring both speed and reliability are maintained through continuous adaptation to changing network states.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes routing parameters dynamically by selecting different access methods based on monitored delay metrics. When the delay parameter exceeds a threshold indicating service degradation, the system modifies the routing decision to use an alternative access method, thereby resolving the contradiction between maintaining connection speed and avoiding service degradation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If multiple access methods are monitored and monitored continuously, then service degradation is detected earlier, but system complexity increases

Engineering Contradiction:

Improveservice degradation detectionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system implements self-service monitoring where access methods autonomously report their connection delay metrics to the routing system. This self-reporting mechanism enables automatic detection of service degradation without requiring complex centralized monitoring infrastructure, thus improving reliability while minimizing system complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback from connection delay metrics to automatically detect service degradation. By continuously receiving delay information from multiple access methods and comparing it against thresholds, the system achieves early detection of degradation events through a relatively simple feedback-based mechanism rather than complex analysis systems.

Inventive Principle:

Principle #23Feedback
