Standardized AT Commands for UE Coverage Mode Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to determine whether a user equipment (UE) is in Enhanced Coverage (EC) mode during field tests and laboratory tests, and end users need to identify if a UE is in CE mode and what mode it is, as this information is not readily available from chipset vendors or original equipment manufacturers.
Innovation Solution
The implementation of standardized commands, such as AT commands, allows UE devices to indicate their device type, coverage enhancement mode, and repetition numbers for physical channels, enabling network devices to determine the CE mode and settings through commands like +PADT?, +PACEM?, and +PARN?, facilitating CE mode determination and communication improvements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standardized commands are implemented to indicate CE mode and settings, then measurement precision and information availability are improved, but device complexity and standardization requirements increase
Solution Approach 1:
The patent applies parameter changes by introducing standardized AT commands with specific parameter structures to indicate CE mode and settings. The commands define particular parameters (device type, coverage mode, repetition numbers) that transform the information exchange process, enabling precise determination of CE modes through structured parameter reporting rather than ad-hoc methods
Solution Approach 2:
The patent segments the information about CE mode into distinct, standardized command components. Each AT command focuses on specific aspects (device type indication, coverage mode indication, repetition number indication), breaking down the complex state reporting into manageable, standardized segments that can be processed independently
2Loss of information
If standardized commands are implemented for CE mode indication, then information availability and testing efficiency are improved, but ease of operation decreases due to standardization requirements
Solution Approach 1:
The patent applies universality by creating a standardized AT command framework that serves multiple functions: indicating device type, coverage mode, and repetition numbers through a unified command structure. This universal approach allows the same command mechanism to handle various information types, reducing the need for device-specific custom solutions
3Reliability
If standardized commands are implemented to indicate device type and coverage mode, then reliability of CE mode determination is improved, but device complexity increases due to command implementation requirements
Solution Approach 1:
The patent applies parameter changes by defining specific parameters within the AT command structure that reliably indicate device type, coverage mode, and repetition numbers. These standardized parameters ensure consistent interpretation across different devices and networks, improving determination reliability through parameter standardization rather than proprietary methods
