Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current mobile and computing devices are limited in sharing VoIP sessions across multiple devices, restricting communication to a single device during a session, which is undesirable in scenarios where sharing portions of the session across multiple devices would be beneficial.

Innovation Solution

A method and system that enable multiple devices to communicate by initiating a multimedia communication session, identifying and directing portions of the session to additional devices using unique identifiers, allowing seamless routing across a network of connected devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a VoIP call is restricted to a single device during the session, then call management is simplified, but the ability to share communication across multiple devices is lost

Engineering Contradiction:

Improveability to share VoIP session across multiple devicesVSAvoidcall management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the VoIP session into separate audio and video streams. Each stream can be independently routed to different devices, allowing the audio portion to remain on one device while video is shared on another, thereby enabling multi-device sharing without overwhelming complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a call management system that acts as an intermediary between the VoIP session and multiple devices. This mediator handles the complexity of routing different session portions to different devices, shielding users from the underlying complexity while enabling versatile sharing

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple devices are connected to share a VoIP session, then communication versatility is enhanced, but session routing complexity increases

Engineering Contradiction:

Improvecommunication sharing capabilityVSAvoidsession routing ease

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent performs preliminary actions by pre-establishing the multi-device connection framework before the VoIP session begins. Devices are pre-configured and registered with the call management system, so when a session starts, the routing is already prepared and can be activated without complex real-time operations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates copies of the VoIP session streams and directs them to different devices. Instead of complex real-time routing decisions, the system creates duplicate streams that can be independently directed to various devices, simplifying the operational complexity

Inventive Principle:

Principle #26Copying

AI summary

A method for allowing multiple devices to communicate includes initiating a multi-media communication session between a first device and a second device, each of the first and second device having access to at least one additional device, identifying at least a portion of the multi-media communication session to direct to the at least one additional device, the first device obtaining a unique identifier of the at least one additional device and directing the identified at least a portion of the multi-media communication session to the at least one additional device.
