Solution Overview

Problem

User equipment (UE) often displays incorrect or unintelligible network information due to unsupported character formats when receiving network name information from wireless networks, leading to user confusion and a poor user interface experience.

Innovation Solution

The UE method involves skipping unsupported characters in network information strings and prioritizing features to display only supported indicia, such as using the USIM, NITZ, or stored ME information to ensure proper display of network identifiers, thereby avoiding the use of unsupported formats and features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the UE displays all received network information indicia, then the information completeness is improved, but the display reliability deteriorates due to unsupported character formats causing incorrect or unintelligible characters

Engineering Contradiction:
Improvenetwork information completenessVSAvoiddisplay accuracy
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

The patent segments the network information string into individual indicia (characters) and processes each one separately. The UE determines support for each indicium individually and displays only those that are supported, while skipping unsupported ones. This segmentation allows the system to preserve displayed information accuracy while maintaining partial information completeness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and removes unsupported indicia from the network information string before display. By identifying and excluding characters that the UE cannot properly render (such as certain Unicode characters or special symbols), the system ensures that only reliable, displayable information is shown to the user, thus maintaining display accuracy.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the UE uses multiple features (USIM, NITZ, ME information) to display network information, then the adaptability is improved, but the device complexity increases due to feature prioritization and selection logic

Engineering Contradiction:
Improvenetwork information display flexibilityVSAvoidfeature selection complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by establishing a predetermined priority order among different information sources (USIM > NITZ > ME information) before actual network information display is needed. This prioritization scheme is configured in advance, allowing the UE to automatically select the appropriate feature without complex real-time decision-making, thus reducing operational complexity while maintaining adaptability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent enables self-service by allowing the UE to autonomously determine which indicia are supported and which should be skipped without external intervention. The device automatically manages the selection and display process based on its own capabilities and the prioritization scheme, reducing the need for complex user configuration or network-side control.

Inventive Principle:
Principle #25Self-service

AI summary

A user equipment (UE) comprising a display and a processor configured to determine whether the UE supports each indicium of a string of one or more indicia according to a first feature, the string of one or more indicia identifying a network, the processor further configured to display on the display of the UE only the indicia in the string that are supported by the UE. A method implemented on a UE comprising determining whether the UE supports one or more indicium of a string of one or more indicia according to a first feature, the string of one or more indicia identifying a network, and displaying on the display of the UE only the indicia in the string that are supported by the UE.
