Wireless Device Logging Out-of-Service Coverage During SIM Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly during Multi-Universal Subscriber Identity Module (MUSIM) operations, there is a challenge in accurately reporting out-of-service coverage areas, as existing methods fail to provide clear indications of when out-of-service conditions are encountered while switching between networks, leading to potential misinterpretation of coverage sizes in logged measurement reports.
Innovation Solution
A method and apparatus for a wireless device to register with multiple networks, receive logging instructions, detect out-of-service coverage upon switching between networks, and generate logging information that includes an indication of when out-of-service conditions are detected, allowing for accurate reporting of coverage areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If logging information is reported without indicating network switching context, then the reporting process is simple, but the coverage area measurement becomes inaccurate
Solution Approach 1:
The logging information is segmented into distinct components: basic out-of-service coverage data and network switching context information. This segmentation allows the measurement accuracy to be improved by adding contextual information while keeping the basic logging structure intact and manageable.
Solution Approach 2:
Network switching indication information acts as an intermediary element that connects the out-of-service coverage measurement with the contextual understanding of network operations. This intermediary provides the necessary context without fundamentally changing the core logging mechanism.
2Loss of information
If network switching indication information is added to logging reports, then coverage measurement accuracy improves, but the information processing complexity increases
Solution Approach 1:
The network switching indication information is collected and prepared in advance during the network switching process, before the out-of-service coverage measurement is completed. This preliminary action ensures that when the logging information is generated, all necessary contextual information is already available, reducing processing complexity at the reporting stage.
Solution Approach 2:
The logging system incorporates feedback mechanisms that track network switching events and automatically associate them with subsequent out-of-service coverage measurements. This feedback loop ensures information completeness without requiring complex manual processing or analysis.
