Subscriber Initiated Call Reconnection via Server Handoff

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Poor channel quality and dropped calls in mobile communication networks lead to user dissatisfaction and churn, with no mechanism for users to automatically request compensation for poor quality links or dropped calls.

Innovation Solution

A system that includes a communication server capable of establishing and managing voice connections between handsets, allowing users to request improved call quality by disconnecting and reconnecting calls through a designated server, using remote origination technology to bypass network operators and switch calls between different networks for better coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user terminates the conversation and tries the call again after poor quality or dropped call, then the user may achieve better call quality, but the user experience deteriorates due to repeated attempts and time loss

Engineering Contradiction:

Improvecall qualityVSAvoidtime for repeated call attempts

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically detecting poor call quality or dropped calls and initiating the call reconnection process without waiting for user action. The server proactively identifies when a call needs to be reconnecting and executes the reconnection logic, thereby preventing time loss while maintaining call quality improvement.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The call reconnection system operates autonomously without requiring user intervention. The server automatically monitors call quality, detects issues, and executes the reconnection process using the handset's own resources and network capabilities, eliminating the need for users to manually terminate and redial.

Inventive Principle:

Principle #25Self-service

2Reliability

If the user manually reestablishes the call after connection problems, then the call can be reconnecting, but the ease of operation decreases due to additional user actions required

Engineering Contradiction:

Improvecall reconnection capabilityVSAvoiduser interaction requirement

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables self-service operation where the server automatically monitors call quality parameters, detects poor quality or dropped calls, and initiates the reconnection process without requiring any user actions. The handset and server work autonomously to restore the call connection.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors call quality through feedback mechanisms and automatically triggers reconnection when quality thresholds are violated. This closed-loop feedback system ensures reliable call maintenance without manual user intervention.

Inventive Principle:

Principle #23Feedback

3Reliability

If the system establishes a new voice connection by disconnecting and reconnecting, then call quality improves, but the device complexity increases due to additional server configurations

Engineering Contradiction:

Improvecall quality improvementVSAvoidserver configuration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The server leverages existing multi-functional capabilities already present in the network infrastructure for call management, routing, and quality monitoring. By utilizing these universal functions, the system achieves call quality improvement without adding separate dedicated complexity for the reconnection function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system changes operational parameters such as connection routing, network path selection, and call routing parameters to achieve quality improvement. These parameter modifications are implemented through existing server capabilities rather than requiring complex new hardware or system architectures.

Inventive Principle:

Principle #35Parameter changes

4Device complexity

If there is no mechanism for users to automatically request compensation for poor quality links or dropped calls, then the system remains simple, but user satisfaction and loyalty deteriorate

Engineering Contradiction:

Improvesystem simplicityVSAvoiduser satisfaction

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system implements feedback mechanisms that automatically detect poor call quality and trigger compensation requests. Users receive automated notifications or credits based on the detected quality issues, maintaining system simplicity while improving user satisfaction through automatic service recovery.

Inventive Principle:

Principle #23Feedback
