The CEO of the Quan-Zhi Inc. states that the development of the Service Assurance Platform for 5G Vertical Application starts from a private network simulation system. It provides various terminal devices and vertical applications under the SA structure in 5G private networks, simulating various behaviors of terminals and private networks. The platform effectively provides a private network planning solution across end-to-end devices, applications, and structures, which suppress traditional hardware devices that only target specific components. Prof. Ta-Sung Lee points out that 5G public networks and 5G private networks have different environments and vertical applications (such as Smart Manufacturing and Smart Healthcare), requiring different know-how. His team researches the technology of 5G private networks and evaluates the possibility of commercializing the private network using vertical applications to expand the value of their research. Their work can also accelerate the research and deployment of 5G private networks in Taiwan.

Quan-Zhi Inc. transfers multiple technologies and intellectual property rights from NYCU to build a Private Network Simulation System, which simulates behaviors of terminal users and IoT devices in an OTA interface. They develop various evaluating models such as 5G academic private networks, 5G Smart Manufacturing, and 5G Smart Healthcare. Furthermore, they cooperate with the O-RAN Alliance and plan to provide the 5G private-network evaluating tools and methods to network industry, operators, government, and international standards organizations, which will accelerate the development of their products and elevate their testing quality.

The Service Assurance Platform for 5G Vertical Application includes the private network simulation system as the first stage. It can also integrate the Vertical Application Data Analysis System for maintenance and management and Vertical Application Optimization System with AI. With the simulation data from the simulation system and the big data from the terminals in 5G private networks, the platform provides a 5G private-network management system to manage and maintain the networks. It can also optimize the performance and warn users in real-time about the security problem, using the data collected by the simulation system. For example, a Smart Factory can apply the Service Assurance Platform for 5G Vertical Application to evaluate the influences on the private network after building a new plaint, updating an old plaint, or changing a production line. It can also be applied for planning the networks in advance, warning in real-time, and continuously optimizing the network. The platform customizes its modules for different types of private networks and tests the overall system performance and security to elevate management efficiency. Working with 5G performance analysis matrices, the Platform can rapidly clarify the difference between the planned network and the reality, which reduces the errors of using human resources and experience. Moreover, it can evaluate the performance and technology of the private networks and satisfy different demands of services.

The CTO of Quan-Zhi Inc. stated that 5G private networks and 5G public networks have significant differences, such as the complexity of the antenna technology in the PHY layer and the effect of the private network performance caused by no-brand or small base station devices (e.g., O-RAN, Small-Cell). The cooperation between the base station and the 5G SA core network and the MEC cloud computing and services significantly delays the development and deployment of 5G private networks. The technology in the system is far more complex than traditional IP wireless routers or bridges. Therefore, in the era that the open architecture competes with 5G public and private networks, Quan-Zhi Inc. mainly focus on developing a continuously growing validation and maintenance system, allowing 5G private-network devices and fields to be thoroughly tested on their performance and securities in Taiwan. As a result, these device companies can reduce the dependencies on foreign companies, advance technology development, and commercialize their products.
