Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current alert mechanisms in telecommunications lack flexibility and interactivity, requiring pre-recorded ringtone files on the network and access to the internet, which limits customization and user interaction during call establishment.

Innovation Solution

A method for sending a multimedia stream from the calling device to the called device during call setup, allowing real-time customization of alerts such as ringtones, vibrations, or video messages without prior file recording, using a bidirectional communication channel and a message server to buffer and transmit multimedia content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If pre-recorded ringtone files are saved on the network before call initiation, then alert mechanisms can be configured, but flexibility and interactivity are reduced and internet access is required

Engineering Contradiction:

Improveflexibility and interactivity of alert mechanismsVSAvoidrequirement for file saving and internet access

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by enabling alert mechanisms to be dynamically generated and transmitted during call establishment rather than being pre-configured. The calling device can send multimedia streams (audio, video) directly during the call setup phase, allowing real-time customization without requiring prior file saving or internet access. This transforms static pre-recorded alerts into dynamic interactive alerts.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent uses an intermediary approach by introducing a server that facilitates the transmission of alert messages between calling and called devices. The server receives the alert message from the calling device, buffers it, and transmits it to the called device during call establishment, enabling flexible alert delivery without requiring direct peer-to-peer file transfer or internet access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If classic telephone answering system mechanism is implemented with bidirectional communication, then user choice is enabled, but additional communication channel establishment is required

Engineering Contradiction:

Improveuser choice in answering callsVSAvoidbidirectional communication channel establishment

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies the merging principle by combining the alert message transmission and bidirectional communication channel establishment into a single integrated process during call establishment. The server buffers the alert message and establishes communication channels that enable both alert delivery and user interaction in one operation, rather than requiring separate processes.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The method to send an alert message in a telecommunications network comprises a reception step (E20) of a multimedia flow sent by a calling device having made a call to a called device, and a transmission step (E30) to the called device, during the call setup phase, of at least part of the multimedia flow, which may be reproduced, at least partially, by alert means of the called device.
