UICC Multi-Operator Profile Selection Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices often face challenges in managing multiple subscriptions with different mobile network operators, particularly when users need to switch between subscriptions based on location or purpose, such as business vs. personal use, due to limitations in current SIM card configurations.
Innovation Solution
A Universal Integrated Circuit Card (UICC) configured for multiple subscriptions, allowing users to select or automatically activate different mobile network operator profiles based on user input or criteria like signal strength, with a subscription system maintaining lists of partner operators and update files for seamless network switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a SIM card is configured for a single subscription with one mobile network operator, then the device complexity is reduced and ease of operation is improved, but the adaptability to different geographic areas and purposes deteriorates
Solution Approach 1:
The SIM card is configured with multiple subscriptions, each associated with a different mobile network operator, enabling the same SIM card to function with multiple operators. This multi-functionality allows the device to adapt to different geographic areas and purposes without requiring multiple SIM cards or complex manual reconfiguration.
2Productivity
If manual intervention is required to switch between subscriptions, then the device complexity is reduced, but the productivity and ease of operation deteriorate due to time-consuming manual configuration
Solution Approach 1:
The system enables automatic selection and switching between subscriptions based on pre-configured criteria such as geographic location, network signal strength, and user preferences. This self-service capability eliminates the need for manual intervention, allowing the device to automatically connect to the most appropriate mobile network operator without user input.
Solution Approach 2:
The system continuously monitors relevant parameters such as geographic location and network signal strength, and automatically adjusts subscription selection based on this feedback. This closed-loop control enables dynamic optimization of network connection without manual intervention.
3Adaptability or versatility
If multiple SIM cards are used to achieve multiple subscriptions, then the adaptability improves, but the device complexity and loss of substance increase due to carrying and managing multiple cards
Solution Approach 1:
Multiple subscription profiles are merged into a single SIM card, consolidating what would traditionally require multiple separate SIM cards. This integration maintains multi-operator support while eliminating the need to physically carry and manage multiple SIM cards, reducing both device complexity and physical storage requirements.

AI summary
A mobile communication device may include a universal integrated circuit card to store a plurality of mobile network operator (MNO) profiles. The mobile communication device may further include logic configured to retrieve the stored plurality of MNO profiles from the UICC; obtain a list of available MNOs by communicating with base stations located within a transmission range of the mobile communication device; obtain a list of partner MNOs from a subscription system; filter the obtained list of available MNOs based on the obtained list of partner MNOs; and display selectable MNOs based on the retrieved MNO profiles and based on the filtered list of available MNOs.
