Mobile Terminal Call Testing with Pre-Connection Band Compatibility Checks

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mobile terminal test apparatuses face inefficiencies in determining whether call connections are possible due to mismatched Band Combinations between the test apparatus settings and the mobile terminal's capabilities, leading to failed connections and reduced testing efficiency.

Innovation Solution

A mobile terminal test apparatus that acquires UE Capability Information, collates the Band Combination set in the apparatus with the Carrier Aggregation Band Combination List, and displays call connection possibilities on a display unit, allowing pre-connection confirmation and efficient testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the test apparatus uses a fixed Band Combination setting, then the device complexity is reduced, but the adaptability to different mobile terminal capabilities deteriorates

Engineering Contradiction:

Improvetest apparatus configurationVSAvoidBand Combination compatibility

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The test apparatus performs preliminary acquisition and storage of UE Capability Information before conducting actual communication tests. This allows the system to pre-determine compatible Band Combinations and display call connection feasibility in advance, avoiding repeated trial-and-error testing with different frequency band settings.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If the test apparatus performs trial call connections to determine compatibility, then the measurement precision of connection feasibility is improved, but the loss of time increases

Engineering Contradiction:

Improvecall connection feasibility determinationVSAvoidtest time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system displays call connection feasibility information before actual connection attempts are made. By acquiring UE Capability Information in advance and comparing it with the test apparatus settings, the system provides preliminary determination of compatibility, preventing wasted time on注定失败的 connection attempts.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The test apparatus provides feedback information about call connection feasibility to the user before actual testing. This feedback mechanism allows operators to adjust settings or select different Band Combinations based on the predicted outcome, improving overall test efficiency by avoiding unsuccessful trial connections.

Inventive Principle:

Principle #23Feedback

AI summary

To provide a mobile terminal test apparatus capable of confirming whether call connection is possible by using setting of a test apparatus before the call connection and improving efficiency of a test. A control unit 6 that acquires UE Capability Information through communication with a mobile terminal 10, collates whether a Band Combination set in the own apparatus is present in a Carrier Aggregation Band Combination List included in the UE Capability Information, and displays, on a display unit 5, that call connection is possible, in a case where the Band Combination set in the mobile terminal test apparatus is present in the Carrier Aggregation Band Combination List is provided.
