Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hardware components are used to simulate wireless network devices, then simulation accuracy is improved, but resource consumption and cost increase
Solution Approach 1:
The patent creates virtual copies of wireless network devices (base stations, user equipment) that run as software instances on physical servers. These virtual devices replicate the behavior and characteristics of real hardware without requiring physical duplication, thereby maintaining simulation accuracy while significantly reducing the quantity of physical resources needed.
Solution Approach 2:
The patent replaces the mechanical/physical system of actual wireless devices with a software-based simulation system. By substituting physical hardware with virtualized software implementations, the system achieves the same simulation objectives without the resource constraints and costs associated with physical device deployment.
2Quantity of substance
If software-based simulation is used, then resource consumption is reduced, but simulation complexity and time increase
Solution Approach 1:
The patent implements a universal simulation platform that can handle multiple types of wireless network devices and scenarios through a single software infrastructure. This multi-functional system eliminates the need for separate simulation environments for different device types, thereby reducing overall complexity and enabling parallel execution of multiple simulations to improve productivity.
Solution Approach 2:
The patent performs preliminary setup and configuration of simulation parameters, device models, and network topologies before actual simulation execution. By pre-configuring these elements, the system reduces the complexity and time required during actual simulation runs, thereby improving overall simulation efficiency without sacrificing accuracy.
3Adaptability or versatility
If multiple base stations and user equipment are simulated simultaneously, then network scenario realism is improved, but computational load increases
Solution Approach 1:
The patent divides the simulation of multiple base stations and user equipment into separate virtual instances that can be independently managed and executed. Each virtual device is segmented as an independent process or container, allowing the system to handle multiple devices simultaneously while distributing computational load across available resources, thereby maintaining network scenario realism without overwhelming computational demands.

AI summary
A system for simulating a wireless communication network over a wired network may comprise a plurality of physical UEs, one or more RANs, and a channel condition emulator. The plurality of UEs may be coupled to one another through the wired network. The one or more RANs may be simulated in software to simulate data transmissions between the plurality of UEs. The channel condition emulator may be simulated in software to derive channel conditions for each of the plurality of UEs based on their current location. The channel condition emulator may further provide the channel conditions to the plurality of UEs and the one or more RANs.
