Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile network testing equipment is costly and inefficient due to its focus on single functionality, making it difficult to integrate and reduce testing costs in the mobile communication industry.
Innovation Solution
A system and method for emulating a radio device comprising a multi-radio unit, a multi-radio unit controller, and an under-test radio system, which generates and controls radio emulated signals to simulate multiple signal channels, reducing testing equipment costs by centralizing control and data plane signal management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate testing equipment are used for different functionalities, then testing coverage is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple radio units (RU1, RU2, RU3, RU4) and their associated control functions into a single integrated emulated radio device. This multi-radio unit shares common control plane signal processing and data plane signal processing resources, merging what would traditionally require separate testing equipment into one unified system, thereby reducing overall complexity while maintaining comprehensive testing coverage
Solution Approach 2:
The emulated radio device is designed to perform multiple functions simultaneously - it can emulate different radio units, handle various control plane signals, and process multiple data plane signals through a single device. The controller is configured to generate and process diverse signal types (control plane signals and data plane signals) through unified processing paths, making the device universally applicable for testing multiple functionalities
2Measurement precision
If dedicated testing equipment for each function is deployed, then testing precision is improved, but cost increases
Solution Approach 1:
The patent merges multiple dedicated testing equipment functions into a single emulated radio device that shares common hardware resources and processing paths. The control plane signal processing and data plane signal processing are performed by unified components rather than separate dedicated equipment, reducing the quantity of equipment needed while maintaining testing precision through centralized control
Solution Approach 2:
The emulated radio device creates virtual copies of multiple radio units (RU1, RU2, RU3, RU4) within a single physical device. Instead of deploying four separate physical testing equipment, the system uses software-based emulation to create multiple functional instances that share underlying hardware resources, thereby reducing equipment cost while maintaining the precision of individual function testing

AI summary
A system and method of emulating radio device includes a multi-radio unit, a multi-radio unit controller and an under-test radio system. The multi-radio unit includes multiple radio circuits, in which the radio circuits are configured to generate multiple radio emulated signals. The multi-radio unit controller coupled to the multi-radio unit is configured to generate multiple control signals to the multi-radio unit, in which the control signals are configured to control the radio emulated signals sent by the multi-radio unit. The under-test radio system is configured to receive the radio emulated signals generated by the multi-radio unit, and configured to generate multiple data corresponding to the radio emulated signals.
