APDU Pipe Architecture for Multi-SIM Authentication Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing authentication and subscription information, particularly in multi-SIM terminals, where activating and connecting telecom bundles to MODEMs efficiently is complex, limiting user experience and network access flexibility.
Innovation Solution
A method and apparatus that activate telecom bundles on smart secure platforms, forming application protocol data unit (APDU) pipes between the bundles and MODEMs to manage authentication and subscription information, allowing multiple profiles to be simultaneously activated and connected to MODEMs, enhancing user experience and network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple telecom bundles are activated and connected to MODEMs in multi-SIM terminals, then network access flexibility and user experience are improved, but the complexity of managing authentication and subscription information increases
Solution Approach 1:
The patent segments authentication and subscription information management by creating separate APDU pipes for different telecom bundles and MODEM connections. Each bundle-MODEM pair has its own dedicated communication channel, allowing independent management of authentication data without interfering with other bundles, thus reducing overall system complexity while maintaining multi-network access capability
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of APDU (Application Protocol Data Unit) pipes that mediate between telecom bundles and MODEMs. These pipes serve as standardized interfaces that simplify the management of authentication information by providing a uniform method for establishing connections across multiple bundles without requiring complex direct integration between each bundle and MODEM pair
2Ease of operation
If telecom bundles are activated and connected efficiently, then user experience is improved, but the process of forming and managing APDU pipes between bundles and MODEMs becomes complex
Solution Approach 1:
The patent applies preliminary action by pre-establishing the framework for APDU pipe formation and management before actual telecom bundle activation. The system prepares the necessary communication infrastructure, authentication mechanisms, and connection protocols in advance, so that when users activate bundles, the complex pipe formation process has already been simplified and is ready for efficient execution
Solution Approach 2:
The patent uses copying by creating standardized APDU pipe templates that can be replicated for different bundle-MODEM connections. Instead of designing unique communication pathways for each connection, the system uses copyable pipe structures with consistent authentication and data transfer mechanisms, reducing the complexity of forming and managing multiple pipes while maintaining efficient user experience
