Cross-Device Call List Synchronization Via Mobile Phone Links

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Communication devices such as cellular phones, landline phones, and computers remain isolated, requiring users to manually re-enter favorites and preferences across devices due to the lack of information transfer capabilities.

Innovation Solution

A mobile phone connects to other devices via an electronic link, synchronizing call lists, including call logs, text messages, and address book information, through software that transfers or merges this data across devices, either directly or via a central system, enabling automatic call transfers and shared access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually re-enter favorites and preferences into each device, then each device maintains independent and complete user information, but user convenience deteriorates and time consumption increases

Engineering Contradiction:

Improveuser convenienceVSAvoidtime for manual re-entry

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the call list data from multiple communication devices by connecting them through an electronic link. The software on the mobile phone transfers and synchronizes call list information with other devices, allowing users to access their call history across different devices without manual re-entry, thus improving ease of operation and eliminating time loss.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal call list access system where the same call list information becomes accessible across multiple device types (mobile phones, landline phones, computers). This multi-functionality allows users to retrieve their call history from any connected device, resolving the contradiction between device independence and user convenience.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If communication devices remain isolated, then device simplicity and independence are maintained, but information transfer capability deteriorates

Engineering Contradiction:

Improveinformation transfer capabilityVSAvoidsystem isolation

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary software system that facilitates information transfer between isolated communication devices. The software acts as a mediator by transferring call list data from the mobile phone to other devices through an electronic link, enabling information transfer capability while maintaining the relative simplicity and independence of individual devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If call list synchronization is implemented across devices, then user information accessibility improves, but data transfer complexity increases

Engineering Contradiction:

Improvecall list accessibilityVSAvoidsynchronization process

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent inverts the traditional approach by having the mobile phone (the device with complete call list information) actively transfer data to other devices, rather than having other devices request or synchronize data. This inversion simplifies the synchronization process by centralizing the data source and reducing the complexity of bidirectional synchronization protocols.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A communications system according to certain embodiments includes a mobile device and a second type of communications system, such as a landline telephone system, that share usage information. The shared information can include call logs of in-coming and out-going calls, missed calls, text messages, address book information, GPS data, internet browsing data, and the like.
