Solution Overview

Problem

Existing access control systems using short-range communication devices face challenges in secure management and control of access rights, particularly with mobile communication apparatuses that lack direct connectivity to back-end systems, leading to difficulties in software updates and hardware maintenance due to frequent product life cycles and the need for laborious wiring.

Innovation Solution

A mobile communication apparatus with circuits for mobile radio, short-range communication, and location determination, which receives and verifies secured data packages by matching location information between the device and the apparatus, enabling secure data transfer even in off-line modes and preventing fraudulent installations by using multiple communication technologies like RFID, NFC, and BLE.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If short-range communication devices are equipped with multiple communication interfaces (RFID, NFC, Bluetooth) to improve flexibility and versatility, then the number of applications and installations increases, but the secure management and control of access rights becomes more challenging and requires laborious wiring to back-end systems

Engineering Contradiction:

Improveflexibility and versatility of short-range communication devicesVSAvoidcomplexity of secure management and control of access rights

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the back-end system connectivity requirement from the access control functionality by implementing local storage and verification capabilities within the terminal device itself. The secured data package containing access rights is stored locally in the terminal device, eliminating the need for continuous back-end system connection for access control operations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a mobile communication apparatus as an intermediary between the back-end system and the short-range communication device. This intermediary receives secured data packages from the back-end system via mobile radio network and transfers them to the short-range communication device, simplifying the overall system architecture by reducing direct wiring requirements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If stand-alone or off-line terminals are used to reduce wiring complexity, then installation becomes simpler, but maintenance and software updates become difficult

Engineering Contradiction:

Improvewiring complexity of terminal devicesVSAvoidease of maintenance and software updates

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The patent implements a dynamic architecture where the terminal device can operate in both offline mode (as a stand-alone device with local storage) and online mode (with mobile radio connectivity for updates). The system dynamically switches between these modes based on availability of the mobile communication apparatus and network connectivity, allowing flexible maintenance and updates without permanent wiring constraints.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs preliminary action by having the mobile communication apparatus receive and verify secured data packages from the back-end system before transferring them to the short-range communication device. This pre-verification and pre-preparation of access rights data enables the terminal device to be updated remotely without requiring physical access or complex wiring for maintenance operations.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If secured data packages are transferred without location verification, then data transfer speed increases, but security is compromised allowing fraudulent installations

Engineering Contradiction:

Improvespeed of data transfer to short-range communication deviceVSAvoidsecurity of access rights transfer

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms through location verification. The mobile communication apparatus determines its location and verifies it matches the device location information stored in the short-range communication device before transferring the secured data package. This feedback loop ensures that data transfer only occurs when location correspondence is confirmed, preventing fraudulent installations while maintaining efficient transfer speeds when verification succeeds.

Inventive Principle:

Principle #23Feedback

AI summary

For transmitting a secured data package from a computer system to a short-range communication device, the secured data package is transmitted from the computer system via a mobile radio network to a mobile communication apparatus. The mobile communication apparatus is placed in the communication range of the short-range communication device and receives from the short-range communication device a data read request, which includes device location information. The mobile communication apparatus determines the current location of the mobile communication apparatus. In case of correspondence of the current apparatus location with the received device location information, the mobile communication apparatus determines positive access authorization and transfers the secured data package to the short-range communication device.
