Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal testing systems face inefficiencies when trying to control both LTE and 5G NR mobile terminal testing devices in parallel, as they require separate parameter settings and lack a method to determine the appropriate transmission destination for control commands based on the communication standard.
Innovation Solution
A mobile terminal testing system that includes a first LTE device, a second 5G NR device, and a test control device with a command input unit, a command transmission determination unit, and a command transmission unit, which determines the transmission destination of control commands based on the type, device designation, or communication standard, allowing for parallel control of devices supporting different communication standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control methods are used for LTE and 5G NR testing devices, then each device can be controlled according to its specific communication standard, but the control process becomes complex and inefficient when managing multiple devices in parallel
Solution Approach 1:
The control device is designed with multi-functionality to support both LTE and 5G NR communication standards through a unified control interface. The system can automatically identify the communication standard type and switch between different control protocols, allowing a single device to perform multiple testing functions without requiring separate control systems for each standard.
Solution Approach 2:
The control device acts as an intermediary between the operator and multiple testing devices supporting different communication standards. It translates unified control commands into standard-specific instructions, managing the complexity internally while presenting a simplified interface to users. This mediator role enables parallel control of LTE and 5G NR devices without exposing the underlying complexity to operators.
2Ease of operation
If a unified control interface is implemented for both LTE and 5G NR devices, then control simplicity is improved, but the system must handle multiple communication standards which increases internal complexity
Solution Approach 1:
The control device internally segments handling of different communication standards through dedicated modules or pathways for LTE and 5G NR. This segmentation allows the system to process each standard type through specialized routines while maintaining a unified external interface. The segmentation is transparent to users, who interact with a single control interface regardless of which standard is being tested.
Solution Approach 2:
The control system employs dynamic routing and adaptive protocol selection based on the detected communication standard type. When a testing device is connected, the system dynamically identifies whether it supports LTE, 5G NR, or both, and automatically configures the appropriate control protocol. This dynamic adaptation allows the unified interface to seamlessly handle multiple standards without requiring manual configuration or increasing user-facing complexity.
3Productivity
If manual determination of command transmission destination is used, then flexibility is maintained, but test efficiency decreases due to time-consuming manual operations
Solution Approach 1:
The control device incorporates automatic destination determination functionality that self-identifies the appropriate testing device without operator intervention. When control commands are issued, the system automatically analyzes the command type, checks connected devices' capabilities, and routes commands to the correct destination based on communication standard matching. This self-service capability eliminates manual destination selection, significantly improving test efficiency and reducing operational time.
Solution Approach 2:
The system implements feedback mechanisms where the control device continuously monitors the status and capabilities of connected testing devices. Based on this feedback information, the system automatically determines the appropriate destination for control commands. The feedback loop enables real-time adaptation to device availability and status, ensuring commands are routed efficiently without requiring manual input from operators.
