Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices lack efficient methods to distinguish between terrestrial and non-terrestrial network communications, leading to unnecessary registration operations and potential inefficiencies in network selection and data transmission.
Innovation Solution
The electronic device includes a processor that performs a PLMN search operation, identifies if the selected PLMN is a non-terrestrial network (NTN), and based on certain conditions, skips or performs registration operations, allowing for optimized network selection and user input settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device performs registration operation for all selected PLMNs, then network coverage and service availability are improved, but unnecessary registration operations are performed on NTN PLMNs leading to increased power consumption and processing overhead
Solution Approach 1:
The patent changes the parameter of registration operation execution by introducing a condition-based decision mechanism. The processor determines whether to perform registration operations by evaluating specific conditions (such as whether the PLMN is an NTN PLMN, whether the device is in flight mode, whether data transmission is required). This conditional parameter change allows the device to skip unnecessary registration operations on NTN PLMNs while maintaining registration on terrestrial PLMNs, thereby reducing power consumption without compromising essential network service availability.
2Reliability
If the electronic device performs registration operation for all selected PLMNs, then comprehensive network service is ensured, but network selection efficiency and data transmission performance deteriorate due to redundant operations
Solution Approach 1:
The patent introduces conditional parameters to control the registration operation process. The processor evaluates multiple conditions including PLMN type (NTN vs. terrestrial), device operational state (flight mode, data transmission requirements), and user preferences. By dynamically changing the execution parameter of registration operations based on these conditions, the system improves network selection efficiency by avoiding redundant operations on NTN PLMNs while ensuring comprehensive service coverage through selective registration on appropriate PLMNs.
3Ease of operation
If the electronic device automatically performs registration operations on NTN PLMNs, then network access simplicity is improved, but device complexity increases due to additional protocol stacks and processing requirements
Solution Approach 1:
The patent extracts the decision-making logic for registration operations from the automatic process. Instead of universally performing registration operations on all PLMNs, the system extracts and evaluates specific conditions (PLMN type, flight mode status, data transmission needs) before executing registration. This extraction approach maintains ease of operation by automating the decision process while reducing device complexity by avoiding unnecessary protocol stack initialization and processing for NTN PLMNs where registration is not required.
4Adaptability or versatility
If the electronic device performs PLMN search and registration operations without distinction, then universal compatibility is improved, but differentiation between NTN and terrestrial network handling is lost leading to suboptimal performance
Solution Approach 1:
The patent applies local quality by differentiating the handling of NTN PLMNs versus terrestrial PLMNs based on their specific characteristics. The processor identifies the type of PLMN and applies different processing rules: for terrestrial PLMNs, standard registration operations are performed to ensure compatibility; for NTN PLMNs, registration operations are conditionally skipped or modified based on flight mode status and data transmission requirements. This localized differentiation maintains universal compatibility across network types while optimizing communication efficiency by avoiding redundant operations on NTN PLMNs.
