Mobile Subscription Security Element Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing mobile device subscriptions lack flexibility and security, particularly in ensuring that subscriptions are only accessible within predefined geographic ranges and for limited periods, which is not effectively addressed by current technologies.
Innovation Solution
A method and device for providing a subscription on a security element of a mobile terminal device, where the subscription is managed by a service provider's backend system, allowing access to a mobile network only within permitted positions and for a specified time, using GPS data or mobile radio cell identification to determine the device's location and restrict access accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a subscription is provided on a security element for mobile network access, then communication capability is enabled, but security and control over subscription usage location and time is insufficient
Solution Approach 1:
The patent applies preliminary action by determining the position of the mobile terminal device at time intervals before allowing subscription access. The system proactively checks whether the device is within the permitted position range before granting network access, preventing unauthorized usage rather than reacting to it afterward. This resolves the contradiction by establishing security controls in advance without adding complex real-time monitoring infrastructure.
Solution Approach 2:
The patent implements feedback by continuously monitoring the position of the mobile terminal device at time intervals and using this information to control subscription access. The system receives position information, compares it against the predefined permitted position range, and adjusts network access accordingly. This feedback mechanism provides reliable security control while maintaining relatively simple system architecture by leveraging existing position determination capabilities.
2Reliability
If position determination is performed at time intervals to control subscription access, then unauthorized use is prevented, but loss of time for position checking occurs
Solution Approach 1:
The patent applies periodic action by determining the position of the mobile terminal device at predefined time intervals rather than continuously. This approach maintains reliable access control by regularly checking position status while reducing time consumption compared to continuous monitoring. The system balances security requirements with efficiency by selecting appropriate intervals that prevent unauthorized access without excessive time loss.
3Adaptability or versatility
If subscription access is restricted to predefined position ranges, then geographic control is achieved, but flexibility of subscription usage is reduced
Solution Approach 1:
The patent applies dynamics by making the subscription access control adaptable to different scenarios. The system allows the service provider to define flexible permitted position ranges and time periods, enabling the same subscription mechanism to serve various use cases from highly restricted to more flexible access patterns. This dynamic configuration capability resolves the contradiction by allowing customization that balances geographic control with usage flexibility.

AI summary
The invention relates to a method for providing a subscription on a security element, which security element can be inserted or is a permanently installed part of a mobile terminal. The invention further relates to such a security element. The method comprises the following steps: the subscription is provided on the security element of the mobile terminal of the user, wherein the subscription is kept available by a service provider or goods provider on a background system as a subscription of a plurality of subscriptions and enables the communication via the mobile radio network; and the security element accesses the mobile radio network by means of the subscription provided on the security element. While the security element accesses the mobile radio network, the position of the mobile terminal is determined at time intervals in order to check if the position of the mobile terminal falls in a predefined range of permitted positions, wherein the access of the security element to the mobile radio network is interrupted if the determined position of the mobile terminal does not fall in the predefined range of permitted positions.
