SIM Profile Brokering System for Remote Identity Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication devices require pre-assigned identity information to be loaded onto memory modules at the time of manufacture, limiting flexibility and requiring manufacturers to produce carrier-specific modules.
Innovation Solution
A method and system for remotely providing and updating identity information for mobile communication devices after manufacture, allowing memory modules to be used with different telecommunications carriers and enabling over-the-air replacement of existing identity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If identity information is pre-assigned at manufacture time, then manufacturing process is simple and reliable, but flexibility and adaptability are limited
Solution Approach 1:
The system separates identity information storage from the memory module itself by introducing a server-based storage system. The identity information is segmented into server-stored data and module-stored identifiers, allowing the module to remain simple while the system gains flexibility through remote updates.
Solution Approach 2:
An intermediary system (server) is introduced between the manufacturer and the memory module. This intermediary enables flexible identity assignment and updates without requiring complex manufacturing processes or physical module replacement by end users.
2Ease of manufacture
If carrier-specific modules are produced, then network compatibility is ensured, but manufacturing cost and inventory complexity increase
Solution Approach 1:
The memory module is designed as a universal component that can serve multiple carriers through remote identity assignment. Instead of producing different hardware modules for each carrier, a single universal module design is used with flexible software-based identity configuration enabled by the server system.
Solution Approach 2:
The system changes the identity parameters of the memory module remotely after manufacture. By storing identity information on servers and enabling over-the-air updates, the module's carrier association is transformed from a fixed manufacturing parameter to a flexible runtime parameter.
3Ease of operation
If physical module swapping is required for profile changes, then security is maintained, but user convenience and operation time increase
Solution Approach 1:
The mechanical process of physical module swapping is replaced with an electronic/communication-based system. Identity information is transferred wirelessly over-the-air between the server and the memory module, eliminating the need for physical manipulation by users while maintaining security through encrypted communication channels.

AI summary
A method for receiving identity information for a mobile communication device is provided. The method comprises a memory module on the mobile communication device receiving, over a wireless communication link, a device identifier and an authentication key to replace identity information that had previously been provided to the memory module. The memory module may be one of a subscriber identity module (SIM), a universal integrated circuit card (UICC), a universal subscriber identity module (USIM), or a removable identity module (R-UIM).
