Solution Overview

Problem

Current communication technologies require manual session transfer and prior provisioning, leading to disconnection and credential re-entry when moving between fixed and mobile devices during multimedia communication sessions, lacking seamless convergence and mobility.

Innovation Solution

A system enabling seamless transfer and cloning of multimedia communication sessions, including video and audio, between desktop platforms and mobile devices using QR codes or short-range communication methods like Bluetooth, ZigBee, or WiFi, without the need for prior device association, allowing for continuous communication sessions across different locations and devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual session transfer is used, then device complexity is reduced, but ease of operation deteriorates due to need for manual credential re-entry

Engineering Contradiction:

Improvesession transfer operationVSAvoidprovisioning system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-provisioning devices with unique identifiers and establishing device pairs before actual session transfer is needed. This allows the mobile device to automatically join the communication session without manual credential re-entry, resolving the contradiction between ease of operation and device complexity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mobile device autonomously performs session transfer by scanning the barcode displayed on the desktop device and automatically joining the communication session. This self-service capability eliminates manual intervention for credential re-entry while the provisioning system handles the complexity in the background.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If prior provisioning is required, then reliability of session transfer is improved, but ease of operation deteriorates due to additional setup steps

Engineering Contradiction:

Improvesession transfer operationVSAvoidsession transfer

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary provisioning to assign unique identifiers and establish device pairs before session transfer. This preliminary action ensures reliability by pre-validating device compatibility and permissions, while the actual transfer operation remains simple through barcode scanning.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The barcode serves as an intermediary that encapsulates all necessary session transfer information including device identifiers and session credentials. This intermediary enables reliable automatic session transfer without requiring users to perform complex provisioning steps at transfer time.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If manual credential re-entry is required, then security is improved, but productivity deteriorates due to time loss during location change

Engineering Contradiction:

Improvecommunication continuityVSAvoidsession disconnection

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system performs preliminary provisioning of device pairs and session credentials before mobility occurs. This allows the mobile device to immediately join the communication session upon scanning the barcode, eliminating disconnection during location changes and maintaining communication continuity without compromising security.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuity of the communication session across device transitions by pre-establishing device pairs and using barcode-mediated automatic authentication. This eliminates interruptions and maintains productive communication flow during location changes.

Inventive Principle:

Principle #20Continuity of useful action

4Loss of information

If full session information is transferred, then adaptability is improved, but loss of information is reduced

Engineering Contradiction:

Improvecommunication contentVSAvoidsession transfer system

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The barcode acts as an intermediary that efficiently transfers essential session information including device identifiers, session credentials, and authentication tokens. This intermediary mechanism achieves complete information transfer without requiring complex point-to-point device communication, resolving the contradiction between information completeness and system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Method to clone a communication session from a first device to a second device, including: receiving a request to identify the communication session; rendering an information message comprising an identification of the communication session, wherein the information message is configured to be transmitted from the first device; acquiring the information message from the second device to clone the communication session onto the second device; bridging the second device to the communication session without dropping the first device from the communication session, to produce a cloned communication session; and sending a confirmation message, wherein no prior association between the first device and the second device is used during the cloning.
