Service System Terminal Capability Verification for SIM Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing SIM service systems lack knowledge about the terminal model and SAT command support, leading to the risk of downloading non-functional services to SIM cards, as they do not verify compatibility before installation.
Innovation Solution
Implementing a 'device aware' service system that checks the terminal model and SAT capabilities, using databases or user input to ensure only compatible services are installed, eliminating the need for complex client-side operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If SIM service systems download services without verifying terminal compatibility, then service delivery speed is improved, but service functionality reliability deteriorates
Solution Approach 1:
The service system performs terminal capability verification and compatibility checking before downloading services to the SIM card. The system queries terminal model information, retrieves supported SAT commands from a database, and validates compatibility in advance, ensuring services are only downloaded when the terminal supports them.
Solution Approach 2:
The system establishes a feedback loop where terminal capability information is continuously queried and used to adapt service downloads. The service system receives feedback about terminal model and SAT support, processes this information against a database of required commands, and adjusts service delivery decisions accordingly.
2Reliability
If the service system implements terminal capability verification, then service compatibility is improved, but system complexity increases
Solution Approach 1:
The patent introduces a database as an intermediary component that stores the mapping between terminal models and supported SAT commands. This database acts as a lookup table that simplifies the verification process by providing pre-configured compatibility information, eliminating the need for complex real-time analysis of terminal capabilities.
Solution Approach 2:
The system changes the verification approach from analyzing complex terminal capability parameters in real-time to using simplified lookup operations based on terminal model identifiers. By transforming the verification process into a parameter-matching operation against stored data, the system reduces computational complexity while maintaining accuracy.
3Adaptability or versatility
If SIM applications include terminal support control, then service adaptability is improved, but application complexity increases
Solution Approach 1:
Instead of embedding terminal support control logic within each SIM application, the patent inverts the approach by implementing the verification and control logic in the service system before service download. The service system determines compatibility and selects appropriate services, then downloads only compatible services to the SIM card, eliminating the need for complex control logic in the applications themselves.

AI summary
The invention is concerned with a method in a mobile telecommunication network (4) for managements of services. The services are used by applications in a module (3) of mobile stations (1) through an interface between the application and the terminal (2) of the mobile stations (1). In the method of the invention, a mobile station (1) requests a service from a service system (5) in the network (49). The service system (5) checks the capabilities of the terminal (2) of the mobile station (1) and selects a service functioning in the terminal (2) with respect to the checked capabilities. The mobile station (1) then downloads the selected service. The invention is also concerned with a service system (5) performing the method of the invention.
