Solution Overview

Problem

Current communication systems require multiple devices and complex interconnections for audio and video streaming, making it difficult for users to manage multimedia streams in real time, with mobile terminals primarily acting as accessories to PCs rather than central devices.

Innovation Solution

A method and system for routing multimedia streams using a mobile radio communication station with a first communication interface for radiotelephony networks, involving steps like transferring audio and video streams between the mobile station and a local terminal, managing streams through a processing unit, and routing authorized streams to external devices via a second communication interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple devices are used for audio and video streaming, then the functionality and coverage are improved, but the device complexity and interconnection management become more difficult

Engineering Contradiction:
Improvemultimedia streaming functionalityVSAvoidinterconnection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple communication interfaces (radiotelephony network interface and local wireless interface) into a single mobile terminal device. The terminal acts as an integrated relay station that simultaneously handles network communication and local device communication, eliminating the need for separate capture devices, microphones, and complex interconnections between multiple devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The mobile terminal is designed to perform multiple functions: it serves as both a communication device connected to the radiotelephony network and as a relay station for local devices. The terminal can receive audio/video streams from local devices via Bluetooth or infrared and simultaneously transmit them to the network, making it a universal device that replaces multiple specialized devices.

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

2Adaptability or versatility

If a mobile terminal acts as an accessory to a PC, then the PC's multimedia capabilities are enhanced, but the mobile terminal's role remains limited and secondary

Engineering Contradiction:
Improvemultimedia function extensionVSAvoidmobile terminal autonomy
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Instead of the mobile terminal acting as an accessory to the PC, the patent inverts the relationship by making the mobile terminal the central relay station. The terminal actively manages the routing of audio/video streams between the network and local devices, while the PC becomes one of several possible local devices that can connect to the terminal, thus elevating the mobile terminal to a primary role.

Inventive Principle:
Principle #13The other way round (Inversion)

3Adaptability or versatility

If specific adaptation software is installed for each device, then device compatibility is improved, but the operational complexity and user burden increase

Engineering Contradiction:
Improvedevice compatibilityVSAvoidsoftware installation complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The mobile terminal autonomously manages the compatibility and communication protocols between different devices. The terminal's processing unit automatically handles the routing and adaptation of audio/video streams between devices with different interfaces (Bluetooth, infrared, USB) and the network, eliminating the need for users to manually install and configure adaptation software for each device combination.

Inventive Principle:
Principle #25Self-service

AI summary

The method involves receiving two video/audio streams via a communication interface (101). Routing authorization data associated with an origin of the streams is verified in a data base of a removable identity module by a control unit (4) of a management module (12). The streams are routed toward an outlet port e.g. universal serial bus (USB)or Bluetoothport, of another communication interface (102) by a routing unit (6) for transferring the streams between a radio communication mobile station (1) and a local communication terminal (3) e.g. personal computer. An independent claim is also included for a radio communication mobile station comprising a communication interface.
