Call Status Coordination Across Multiple Communication Devices

Solution Overview

Problem

Current communication systems fail to accurately coordinate the status of calls between multiple devices, leading to incorrect recording of call status as unanswered when one device answers a call intended for multiple devices.

Innovation Solution

A system and method where a processor in one communication device notifies another device that the call was answered, allowing the second device to record the call status as answered, even if it did not receive the call, by monitoring the call or receiving call status data, and using a communication link different from the call communication link.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a call is directed to multiple devices simultaneously, then the possibility of call answering is enhanced, but the call status recording becomes inconsistent across devices

Engineering Contradiction:

Improvecall answering possibilityVSAvoidcall status recording accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system implements feedback by having the first device that answers the call send a notification to the second device about the answered status. This feedback loop ensures that all devices synchronize their call status records, resolving the inconsistency problem while maintaining the multi-device call capability

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent uses a notification message as an intermediary carrier to transmit call status information between devices. This intermediary mechanism allows status coordination without requiring direct communication between all device pairs, solving the status synchronization problem

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If each device independently records call status, then device operation simplicity is maintained, but call history accuracy deteriorates when calls are answered on one device

Engineering Contradiction:

Improvedevice operation simplicityVSAvoidcall history accuracy

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Each device continues to operate independently and record call status on its own without requiring manual intervention. The system maintains operational simplicity while automatically resolving accuracy issues through the notification mechanism that updates status across devices

Inventive Principle:

Principle #25Self-service

AI summary

A method, system and apparatus for coordinating call status are provided. When a call directed to both a first communication device and a second communication device was answered at the first communication device, the second communication device is notified that the call was answered, such that the second communication device records a status of the call as answered.
