Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current public land mobile networks (PLMNs) are static, leading to suboptimal wireless service for devices due to limited configurations, resulting in poor performance, especially when carriers experience downtime or offer inadequate rates, and users may not benefit from better service options based on geographic location.
Innovation Solution
A dynamic roaming PLMN system that uses a processor to determine and update the PLMN configuration for wireless devices based on factors like service quality, rate changes, and user location, allowing for real-time optimization of network connections to ensure optimal service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a static PLMN configuration is used in the SIM card, then the device structure is simple and easy to manufacture, but the wireless service quality deteriorates when carriers experience downtime or offer inadequate rates
Solution Approach 1:
The patent transforms the static PLMN configuration into a dynamic system where the PLMN list can be automatically updated based on real-time conditions. The processor continuously monitors wireless service quality, carrier rates, and geographic location, then dynamically modifies the PLMN configuration in the SIM card to connect to optimal carriers, resolving the contradiction between configuration simplicity and service reliability.
Solution Approach 2:
The system implements a feedback mechanism where the processor monitors wireless service performance and carrier conditions, then uses this information to automatically update the PLMN list. This closed-loop feedback allows the system to maintain simple configuration management while ensuring high service quality by continuously adapting to changing network conditions.
2Device complexity
If a static PLMN list is pre-configured in the SIM card, then the device complexity is low, but the adaptability to different geographic locations and service conditions deteriorates
Solution Approach 1:
The patent makes the PLMN configuration dynamic by enabling automatic updates based on geographic location and service conditions. The processor detects changes in location and carrier performance, then dynamically modifies the PLMN list to include appropriate carriers for the current region, achieving high adaptability without increasing device complexity.
Solution Approach 2:
The system implements self-service functionality where the processor automatically monitors conditions, selects appropriate carriers, and updates the PLMN configuration without user intervention. This self-managing approach provides adaptability to different locations and conditions while keeping the device simple for users.
3Stability of the object's composition
If the PLMN list remains static throughout the SIM card lifecycle, then the configuration is stable and easy to manage, but the wireless service performance deteriorates when better carriers become available
Solution Approach 1:
The patent implements continuous monitoring of wireless service quality and carrier conditions with feedback to the PLMN configuration. The processor receives feedback on service performance and automatically updates the PLMN list to maintain stable configuration management while capturing performance improvements when better carriers become available.
Solution Approach 2:
The system changes the parameters of the PLMN configuration dynamically based on monitored conditions. When service quality or carrier rates change, the processor modifies the PLMN list parameters to reflect current optimal conditions, maintaining configuration stability through systematic updates rather than arbitrary changes.
