Dual SIM Location-Based Service Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling service usage on mobile terminals in communication networks based on location are limited in customization and setup, lacking extensive flexibility and precision in service management.
Innovation Solution
The method involves using dual SIM cards with unique IMSIs and MSISDNs for preferred and remaining areas, stored on a SIM card, and activating the appropriate identifier based on location determination using signal strength and geo-coordinates, allowing for precise service profile switching and billing adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If location-based service control is implemented using conventional methods, then service usage can be differentiated by location, but the customization and flexibility of service management remain limited
Solution Approach 1:
The coverage area is divided into multiple preferred areas and remaining areas, each with distinct service profiles. The mobile terminal maintains separate service configurations for each area type, enabling granular location-based service customization without requiring complex global management systems.
Solution Approach 2:
The mobile terminal autonomously determines its current location, identifies whether it is in a preferred or remaining area, and automatically activates the corresponding service profile. This self-service mechanism eliminates the need for complex external service management setup and enables flexible on-the-fly service adaptation.
2Measurement precision
If service profiles are switched based on location determination, then service management precision improves, but the complexity of location tracking and identifier management increases
Solution Approach 1:
The mobile terminal uses its existing location determination capabilities (signal strength measurement, geo-coordinate acquisition) for dual purposes: both for general network operations and for precise service profile selection. This multi-functional use of existing components achieves precise location-based service control without adding dedicated complex identifier management systems.
Solution Approach 2:
Service area identifiers act as intermediaries between location determination and service profile activation. The terminal determines location, matches it against stored preferred area identifiers, and activates corresponding services. This intermediary layer simplifies the management complexity by using straightforward identifier matching rather than complex real-time service configuration.
3Manufacturing precision
If real-time service profile switching is implemented, then billing accuracy based on location improves, but the processing overhead and system response time increase
Solution Approach 1:
Service profiles for preferred areas and remaining areas are pre-configured and stored in the mobile terminal before actual service usage. When location-based service switching is needed, the terminal simply retrieves and activates the pre-prepared service profile corresponding to the current area type, achieving accurate billing without real-time processing overhead.
Solution Approach 2:
The service profile activation is dynamically triggered by location changes. The terminal continuously monitors location and automatically switches service profiles only when transitioning between preferred and remaining areas. This dynamic approach ensures billing accuracy while minimizing unnecessary processing and maintaining fast response times during stable location periods.
