5G Service Indicator Accuracy via UE Capability Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies often display inaccurate 5G service indicators, misleading users about the availability of 5G radio access technology, leading to poor user experiences and trust issues with telecommunications service providers.
Innovation Solution
Implementing techniques to accurately determine the availability of 5G service by comparing Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) New Radio (NR)-Dual Connectivity (EN-DC) combinations of frequency bands, either by network computing devices or user equipment, to ensure that 5G service indicators are only displayed when the necessary capabilities are supported.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service indicators are displayed to describe available radio access technology, then users can see what services are available, but the indicators can be inaccurate and misleading
Solution Approach 1:
The system implements feedback by having the UE report its supported EN-DC combination capabilities to the network, and the network uses this feedback to accurately determine whether to display the 5G service indicator. This closed-loop information exchange ensures the indicator reflects actual capability availability rather than just network configuration.
Solution Approach 2:
The UE performs self-assessment of its EN-DC combination capabilities and autonomously provides this capability information to the network. The UE serves itself by identifying its own limitations and communicating them, enabling accurate service indicator display without requiring manual configuration or guesswork.
2Ease of operation
If 5G service indicator is displayed to indicate 5G availability, then users can see 5G service status, but it may mislead users when 5G capability is not actually supported
Solution Approach 1:
The system performs preliminary capability assessment by having the UE report its EN-DC combination support before the service indicator is displayed. The network evaluates capability availability in advance and only displays the 5G indicator when capabilities are confirmed to be available, preventing misleading information from appearing in the first place.
Solution Approach 2:
The patent replaces the mechanical/simple approach of displaying service indicators based solely on network configuration with a sophisticated capability-matching system. Instead of a direct mechanical link between network config and indicator display, an information-processing layer compares UE capabilities against required EN-DC combinations to determine indicator visibility.
3Measurement precision
If capability comparison is performed to ensure accurate 5G indicator display, then indicator accuracy improves, but system complexity increases
Solution Approach 1:
The patent extracts the capability comparison function into a dedicated capability determination module that operates independently from the main service indicator display logic. This modular extraction isolates the complexity into a manageable component that specifically handles EN-DC combination capability matching, making the overall system more maintainable and understandable.

AI summary
Determining when to display a Fifth Generation (5G) service indicator is described herein. In an example, a user equipment (UE) can compare capabilities supported by the UE with capabilities available to the UE (e.g., in a geographic area of the UE) to determine whether the UE can display the 5G service indicator. In some examples, such capabilities can be determined based at least in part on E-UTRAN New Radio-Dual Connectivity (EN-DC) combinations of frequency bands.
