Manual-Mode PLMN Search for Disaster-Roaming Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in maintaining service continuity during disaster conditions, with users being unable to efficiently select and register with alternative PLMNs that offer disaster roaming services, leading to service interruptions.
Innovation Solution
A method and system that enables user equipment (UE) to detect disaster conditions, display available PLMNs and supported registration types, allowing users or upper layers to select and trigger appropriate registration procedures, including normal or disaster roaming registrations, ensuring seamless service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic PLMN selection is used during disaster conditions, then service continuity may be maintained through automated roaming, but users cannot efficiently select and register with alternative PLMNs that offer disaster roaming services
Solution Approach 1:
The system dynamically switches between automatic and manual PLMN selection modes based on disaster conditions. During normal operation, automatic selection is used for convenience. When disaster conditions are detected, the system transitions to manual selection mode, allowing users to choose from available PLMNs that offer disaster roaming services, thus ensuring service continuity while maintaining ease of operation through automated mode switching
Solution Approach 2:
The system introduces an intermediary mechanism that provides information about available PLMNs and their disaster roaming capabilities to the user. This intermediary layer guides users through the manual selection process by displaying suitable PLMN options, making the complex registration process more manageable while ensuring users can connect to appropriate networks during disasters
2Adaptability or versatility
If multiple registration types are offered during disaster conditions, then users gain flexibility in registration options, but the registration process complexity increases
Solution Approach 1:
The registration process is segmented into distinct types (normal registration and disaster roaming registration), each with specific characteristics and适用 scenarios. This segmentation allows users to choose the appropriate registration type based on their needs, providing flexibility while keeping each individual registration path relatively simple and manageable
Solution Approach 2:
The system performs preliminary actions by automatically detecting disaster conditions and pre-presenting available PLMN options with their supported registration types before user selection. This preliminary preparation reduces the complexity of the actual registration process, as users are already informed about their options and can make selections without needing to navigate complex registration procedures from scratch
