Secure Module Location-Based Application Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting a payment application on mobile devices based on location context require satellite positioning, which is unreliable in urban areas and extends transaction duration, and are dependent on external devices, leading to user inconvenience.
Innovation Solution
A process and system within the terminal that autonomously obtains location information from a secure module, such as a SIM card, to select the appropriate application, independent of external infrastructure, using telecommunications network data like EFLOCI, allowing for automatic application selection without satellite signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite positioning is used to obtain location information for application selection, then location-based application selection can be achieved, but the system becomes unreliable in urban areas and inside buildings where satellite signals are unavailable
Solution Approach 1:
The patent introduces telecommunications network infrastructure as an intermediary to provide location information. Instead of directly using satellite positioning, the system obtains location data through the telecom network's base stations and network elements, which serve as mediators between the terminal and the location information needed for application selection.
Solution Approach 2:
The patent uses copied or derived location information from telecommunications network data (such as cell tower triangulation, network registration data) as an alternative to direct satellite positioning data. This copied location information from the telecom infrastructure achieves the same purpose without requiring satellite signal reception.
2Ease of operation
If external devices are used to supply location information, then application selection can be performed, but the system becomes dependent on external infrastructure and increases transaction duration
Solution Approach 1:
The patent performs location information acquisition as a preliminary action during terminal startup or network registration, before the actual payment transaction begins. The location data is obtained and stored in advance from the telecommunications network, so when a transaction occurs, the application selection can immediately use the pre-acquired location information without extending transaction time.
Solution Approach 2:
The terminal performs self-service by autonomously obtaining location information from the telecommunications network infrastructure that it already connects to for communication purposes. The system uses its own existing network connection to acquire location data without requiring separate external positioning devices or extending the transaction process.
3Adaptability or versatility
If location information is obtained from the payment terminal, then application selection can be performed, but the system becomes dependent on payment terminal compatibility and infrastructure
Solution Approach 1:
The patent makes the terminal universally adaptable by using the telecommunications network infrastructure, which all mobile terminals already connect to for basic communication. The same telecom network that provides voice and data services also provides location information, making the solution universally applicable to all terminals without requiring special payment terminal infrastructure or compatibility arrangements.

AI summary
The process according to various aspects can be executed by a terminal for selecting an application executable at least in part by a secure module incorporated into the terminal, and may include a step for obtaining location information of the terminal, from a memory of the secure module, and a selection step of an application from the obtained location information.
