Solution Overview

Problem

M2M devices with active subscriptions can inadvertently enable communication via mobile networks if stolen or lost, posing security risks for customers and manufacturers.

Innovation Solution

A method where a mobile terminal device's subscription on a security element is activated only when its position is within a predefined range of permitted locations, using GPS data or mobile cell determination, and the subscription is deactivated outside this range, preventing unauthorized use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the subscription is activated immediately upon delivery of the M2M device, then the device can communicate via mobile network right away, but the device enables communication even if stolen or lost, posing security risks

Engineering Contradiction:
Improveease of useVSAvoidsecurity risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The subscription is pre-configured on the security element but kept inactive until a specific condition (location verification) is met. This preliminary setup allows for quick activation when needed while maintaining security controls, resolving the contradiction between ease of use and security risk

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If the subscription is deactivated until position verification, then security is improved, but the device cannot communicate immediately upon delivery

Engineering Contradiction:
Improvesecurity riskVSAvoidactivation delay
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The system automatically performs location verification and subscription activation without requiring manual intervention. The mobile terminal device itself provides the location data, and the network automatically verifies and activates the subscription when conditions are met, eliminating activation delay while maintaining security

Inventive Principle:
Principle #25Self-service

3Reliability

If location verification is implemented for subscription activation, then unauthorized use is prevented, but the system complexity increases

Engineering Contradiction:
Improvesecurity controlVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The network infrastructure acts as an intermediary that handles the complex location verification and subscription activation logic. The mobile terminal device only needs to provide location data, while the network performs the verification and control functions, maintaining security without significantly increasing device complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for activating a subscription on a security element (14), which is an insertable or permanently installed part of a mobile terminal, and a security element (14) of this kind are described. In this case, the method comprises the following steps: reception of a request from the security element (14) by a mobile radio system to communicate via a mobile radio network (30) of the mobile radio system; ascertainment of the position of the mobile terminal; and checking, by the mobile radio system, to determine whether the ascertained position of the mobile terminal is within a predefined range of permitted positions, wherein the subscription is activated on the security element (14) and this allows the security element (14) to communicate via the mobile radio network if the ascertained position of the mobile terminal is within the predefined range of permitted positions.
