Solution Overview

Problem

Existing telecommunications methods, such as telephone and instant messaging services, often compromise user anonymity and continuity of service, as users are required to disclose their telephone numbers or engage in non-automated processes for temporary numbers, which can lead to service disruptions and number reuse issues.

Innovation Solution

A method and system that automatically generate and broadcast a dedicated telephone number for connecting multiple users without disclosing their personal numbers, allowing for controlled validity periods and secure connections through a messaging server and telephone exchange, ensuring anonymity and preventing number reuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users disclose their telephone numbers to communicate by telephone, then telephone connection is established, but user anonymity is compromised

Engineering Contradiction:
Improvetelephone connectionVSAvoiduser anonymity
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces a messaging server as an intermediary that generates and manages temporary telephone numbers. These temporary numbers act as mediators between users, allowing telephone communication without direct exposure of personal telephone numbers. The messaging server controls the creation, distribution, and destruction of these temporary numbers, ensuring user anonymity while enabling reliable telephone connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If instantaneous electronic messaging services exchange telephone numbers manually, then telephone connection is enabled, but service continuity is interrupted and user privacy is compromised

Engineering Contradiction:
Improvetelephone connection setupVSAvoidservice continuity
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The system implements automated self-service functionality where the messaging server automatically generates temporary telephone numbers, distributes them to authorized users, and manages the connection process without manual intervention. This eliminates the need for users to manually exchange telephone numbers through messaging, maintaining service continuity while enabling telephone connections.

Inventive Principle:
Principle #25Self-service

3Stability of the object's composition

If a permanent telephone number is used for telephone meetings, then connection stability is improved, but number reuse disturbs service and anonymity is lost

Engineering Contradiction:
Improveconnection stabilityVSAvoidservice integrity
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The patent implements dynamic temporary telephone numbers that are created for specific meeting instances and automatically destroyed after use. These numbers are valid only for predetermined time periods and cannot be reused, providing connection stability for each meeting while preventing service disruption through automatic number lifecycle management. The dynamic nature ensures each meeting has a unique, stable number without compromising future service integrity.

Inventive Principle:
Principle #15Dynamics

AI summary

Connecting two or more persons by telephone without any person having to give their telephone coordinates. A messaging server adapted to send to one or more invited persons a message sent by an inviting person and containing an invitation to communicate by telephone, to create automatically a number dedicated to a telephone call in which at least one invited person has agreed to participate, and to broadcast the dedicated number to the inviting person and to the invited person(s) who have agreed to participate. An exchange is adapted to connect at least two calls to the dedicated number.
