Solution Overview

Problem

Current communication stream transfer methods are limited to local networks and cannot seamlessly transfer between different types of communication streams, such as telephony and videophone, or across distinct telecommunications networks.

Innovation Solution

A method that establishes an auxiliary communication channel to request and establish a second communication flow, independent of the first, allowing transfer between any type of terminal and network, with capabilities to handle various communication streams and networks, including simultaneous streams, and transparently manage authentication and connection parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If specialized switches (PABX) are used to transfer communication streams, then the transfer can be effected within the local network, but the equipment cannot transfer communications outside the local network and cannot transfer between different types of communication streams

Engineering Contradiction:
Improvetransfer capability between different terminal types and networksVSAvoidequipment requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a communication relay as an intermediary component that coordinates between the first terminal, second terminal, and third terminal. The relay receives transfer requests, establishes the second communication channel, and manages the transition without requiring complex specialized switches at each terminal. This mediator approach enables versatile transfer capabilities while keeping terminal devices relatively simple.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication relay is designed with multi-functional capabilities to handle various types of communication streams (telephony, videophone, data, multimedia) and support transfers between different terminal types and networks. This universal design allows a single relay to perform multiple transfer operations across diverse communication scenarios without requiring specialized equipment for each case.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If an additional communication channel is established for transfer, then the transfer request and second communication flow can be set up, but the first communication channel remains occupied until the second is established

Engineering Contradiction:
Improvecommunication continuityVSAvoidchannel occupation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system establishes the second communication channel in advance before fully transitioning from the first channel. The relay coordinates the setup of the new channel while the first channel remains active, allowing the transfer to be prepared beforehand. This preliminary action ensures that when the transition occurs, communication continuity is maintained without interruption or loss of time.

Inventive Principle:
Principle #10Preliminary action

3Extent of automation

If the transfer procedure is made transparent to the user, then automatic authentication and parameter management can be performed, but the system must handle complex authentication data and connection parameters

Engineering Contradiction:
Improveautomatic transfer managementVSAvoidauthentication and parameter management system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The communication relay performs self-service by automatically managing authentication data and connection parameters without requiring user intervention. The relay handles the complex tasks of authenticating terminals, negotiating communication parameters, and establishing channels autonomously. This self-service capability provides full automation to the user while the relay's internal systems manage the complexity of authentication and parameter handling.

Inventive Principle:
Principle #25Self-service

AI summary

The method comprises the following steps: - establishment (S10) of a first stream (FU1) via a first communication path between a first terminal (T1) and a second terminal (12), - opening (S15) of a second communication path between the second terminal (T2) and the first terminal (T1), - sending (S20) to the first terminal (T1), via the second communication path, of a request to establish a communication stream (FU2) between the first terminal (T1) and a third terminal (T3) via a third communication path, - comparison (S25) of the respective capacities of the first and third terminal so as to determine whether the establishment of a communication stream is possible between the first terminal and the third terminal, and if so, interruption (S35) of the first stream (FU1) and establishment (S40) of a communication (FU2) stream (FU2), termed the second stream, between the first terminal (T1) and the third terminal (T3).
