Solution Overview

Problem

Current mobile terminal testing apparatuses face challenges in setting the correct combination of frequency bands for carrier aggregation tests, as the specific frequency bands supported by the mobile communication terminal are unknown, leading to lengthy setup times and inefficiencies.

Innovation Solution

A mobile terminal testing apparatus that acquires UE capability information from the mobile communication terminal to set frequency information for each component carrier based on a carrier aggregation band combination list, allowing users to easily select and display the appropriate frequency bands for testing, including differentiation between primary and secondary component carriers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the testing apparatus manually configures frequency bands without acquiring UE capability information, then the setup process is simple, but the test accuracy and reliability deteriorate because the incorrect frequency band combination may be selected

Engineering Contradiction:

Improvetest accuracyVSAvoidsetup process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The mobile communication terminal automatically provides its own capability information (supported frequency bands and carrier aggregation combinations) to the testing apparatus through standardized signaling protocols. This self-service mechanism eliminates the need for manual configuration by the operator, ensuring the testing apparatus selects the correct frequency band combination while maintaining a simple automated setup process.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The testing apparatus acquires UE capability information through communication signaling between the terminal and the testing apparatus. This feedback loop allows the testing apparatus to automatically adapt its configuration based on the actual capabilities of the terminal being tested, ensuring test accuracy without requiring complex manual setup procedures.

Inventive Principle:

Principle #23Feedback

2Productivity

If the testing apparatus manually configures each component carrier frequency band, then flexibility in selection is maintained, but the test setup time increases significantly

Engineering Contradiction:

Improvetest setup speedVSAvoidconfiguration time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The UE capability information containing the list of supported carrier aggregation frequency band combinations is acquired in advance during the initial communication phase between the terminal and the testing apparatus. This preliminary action provides the testing apparatus with all necessary configuration data before the actual test begins, enabling rapid setup without time-consuming manual configuration of each component carrier.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The acquired UE capability information serves multiple functions: it identifies supported frequency bands, determines available carrier aggregation combinations, and configures the testing apparatus parameters all in one automated process. This multi-functional approach significantly reduces configuration time compared to manual setup of each parameter individually.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the testing apparatus uses automated frequency band selection without displaying options, then setup simplicity is improved, but user control and adaptability are reduced

Engineering Contradiction:

Improvesetup simplicityVSAvoiduser selection flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The testing apparatus displays the carrier aggregation band combination list that is actually supported by the terminal (acquired through UE capability information) to the user. This feedback mechanism provides users with accurate, terminal-specific options rather than generic presets, enabling both simple automated operation and user-controlled adaptability when needed.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The displayed frequency band options dynamically adapt to the specific terminal being tested, based on the acquired UE capability information. This dynamic adjustment maintains ease of operation by automatically tailoring the interface to the terminal's capabilities while preserving user flexibility to select from the actual supported combinations.

Inventive Principle:

Principle #15Dynamics
