Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

When testing a mobile terminal that supports Non-Standalone (NSA) communication, the existing mobile terminal testing devices face increased processing load due to the need to generate and transmit control signals for both LTE and 5G NR standards, particularly when a 5G NR control signal is handled by an LTE testing device.

Innovation Solution

A mobile terminal testing system comprising two devices, where one device generates and transmits control signals for standards it does not support, allowing the other device to handle the signal transmission according to its supported standard, thereby reducing processing load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an LTE mobile terminal testing device generates a control signal based on 5G NR setting information, then the testing device can support NSA communication testing, but the processing load of the testing device increases

Engineering Contradiction:

Improvecommunication standard supportVSAvoidprocessing load

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The testing system is divided into two specialized devices: a first mobile terminal testing device for LTE testing and a second mobile terminal testing device for 5G NR testing. Each device handles only the control signals for its supported standard, avoiding the need for one device to process multiple standards internally.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A controller acts as an intermediary between the two testing devices and the mobile terminal. The controller receives control signals from either testing device, translates them into the appropriate standard for the mobile terminal, and manages the overall testing coordination, thereby reducing the processing burden on individual testing devices.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a single testing device handles both LTE and 5G NR control signals, then device versatility is improved, but the processing load and testing efficiency deteriorate

Engineering Contradiction:

Improvecommunication standard supportVSAvoidtesting efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The testing functionality is segmented into two separate specialized devices rather than one multi-functional device. The first device专门 handles LTE testing while the second device专门 handles 5G NR testing, allowing each to operate at optimal efficiency without the overhead of supporting multiple standards.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The two specialized testing devices are merged into a coordinated testing system that works together through the controller. This combination achieves both versatility (supporting both LTE and 5G NR standards) and high productivity (each device operating efficiently in its specialized domain).

Inventive Principle:

Principle #5Merging (Combining)
