Solution Overview

Problem

Mobile terminal testing apparatuses face difficulties in supporting various types of testing, especially when the number of cells required exceeds the maximum prepared, making it challenging to perform tests like handover with multiple cells due to the need for more than twice the normal number of cells for testing.

Innovation Solution

A mobile terminal testing apparatus that includes a cell state determination unit, a cell state change processing unit, and a scenario processing unit to dynamically manage and reuse available cells by initializing and reconfiguring cell states based on messages exchanged with the mobile communication terminal, allowing for the addition or deletion of cells as needed to support multiple cell communication schemes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of cells is increased to support various types of testing including handover testing, then the testing capability is improved, but the device complexity and mounting difficulty increase significantly

Engineering Contradiction:
Improvetesting capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a cell recycling mechanism where cells that have completed their testing function are discarded from active use and recovered through re-initialization. The cell management unit detects when a cell is no longer needed for current testing scenarios, marks it as available for recycling, and re-initializes it for future use. This allows the same physical cell resources to be reused across multiple testing scenarios, effectively increasing testing capability without adding more physical cells.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The patent introduces dynamic cell management where the cell pool is not fixed but can change over time. The cell state transitions between different states (active, inactive, available for recycling) based on testing requirements. The system dynamically allocates and deallocates cells during testing operations, allowing flexible adaptation to different testing scenarios including handover testing without requiring a permanently expanded cell infrastructure.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the number of cells is increased to support multiple cell communication schemes, then the communication testing capability is improved, but the mounting difficulty increases making it very difficult to increase the number of cells

Engineering Contradiction:
Improvecommunication testing capabilityVSAvoidmounting difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent makes each cell multi-functional by enabling it to serve multiple testing purposes through re-initialization. A single cell can be configured for different communication schemes (carrier aggregation, dual connectivity, handover) at different times. The cell management unit handles the reconfiguration, allowing the same physical cell to universally support various communication testing scenarios, eliminating the need to mount separate dedicated cells for each testing type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of permanently allocating cells for specific communication scheme testing, the system discards cells from their current testing role and recovers them for new testing purposes. When a cell completes its function in one communication scheme test, it is marked as available and can be re-initialized for a different communication scheme test, reducing the total number of cells needed for mounting.

Inventive Principle:
Principle #34Discarding and recovering

3Productivity

If cells are reused after deletion to support various testing scenarios, then the productivity is improved, but the risk of state conflicts and communication failures increases

Engineering Contradiction:
Improvetesting efficiencyVSAvoidcommunication reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent performs preliminary re-initialization of cells before they are reused in new testing scenarios. The cell management unit detects when a cell becomes available, re-initializes it to clear any residual state from previous usage, and only then makes it available for new testing. This preliminary action ensures that reused cells start from a clean state, preventing state conflicts and maintaining communication reliability while enabling continuous testing productivity.

Inventive Principle:
Principle #10Preliminary action

AI summary

The mobile terminal testing apparatus including: a cell state determination unit 16 that determines in-use states of multiple cells which perform communication with a mobile communication terminal 2; a cell state change processing unit 17 that changes states of the multiple cells and notifies the cell state determination unit 16 of the states of the multiple cells; and a scenario processing unit 15 that detects the number of cells that need to be added and the number of cells that are available for deletion, based on a message that is transmitted and received between the mobile terminal testing apparatus and the mobile communication terminal 2, and that causes the cell state change processing unit 17 to perform initialization of a cell that is available for deletion, and sets the cell to be available for re-use.
