The Essential Role of the 5G Core Network in the ICT Convergence Era
As the Fourth Industrial Revolution and Digital Transformation (DX) accelerate, innovative services like autonomous driving, smart cities, and the metaverse demand massive data surges and Ultra-Low Latency communication. The core foundation meeting these requirements is the performance and stability of the 5G Core Network Infrastructure. Since the Core Network acts as the ‘brain’ that controls all traffic and determines service quality, its importance is absolute. Furthermore, as telecommunication networks function as public services—a vital necessity like electricity or water—neglecting Network Infrastructure investment in the AI Era can lead to significant social issues. Ariatech recognizes this public value and utilizes its 5G Core technology to secure a stable and reliable network environment, thereby sustaining the foundation of AI Era infrastructure.
Ariatech's 5G Core Components and Technological Superiority
Ariatech’s 5G Core Solution manages key functions of the network—policy control, data management, and service quality maintenance—which are critical in determining the stability and quality of telecommunication services. Our core technologies, the Policy Control Function (PCF), Unified Data Management (UDM), and Unified Data Repository (UDR), are supplied to major Korean telecommunication companies and recognized for their High-Performance. These solutions handle millions of subscriber and session data in real-time, adapting flexibly to traffic changes and serving as the technological base to maintain service quality at the highest level.
◼ Real-time Policy Control via PCF/PCRF-FE
PCF/PCRF-FE performs real-time control over Quality of Service (QoS) and charging policies per user based on the HTTP2/DIAMETER protocol. Structurally, it utilizes a large in-memory real-time database, efficiently managing traffic even in ultra-low latency environments and providing the Rule Control function that differentiates service quality.
◼ High-Availability Data Management via UDM/UDR
UDM manages the integrated overall subscriber and session information, while UDR acts as the central database for 5G/4G/IMS Core Network facilities. Specifically, UDR supports the integrated storage and management of user and supplementary service data through features like data backup/restore and duplication (Duplicating). This system ensures High-Availability, allowing Ariatech’s Solution to enable safe, 24/7/365 communication service operations without data loss.
| 5G Core Solution | Key Function | Technological Superiority |
|---|---|---|
| PCF/PCRF-FE | Policy control based on HTTP2/DIAMETER protocol, Rule Control function | Real-time application of service-specific QoS and charging policies, Ultra-low latency control |
| UDM | Maintaining overall user and session information, managing network subscription/notification | Real-time data processing and High-Availability assurance |
| UDR | Acts as the backend database for 5G UDM/PCF, 4G HSS/PCRF-FE, etc. | Integrated storage and management of user and supplementary service data |
Building Social Trust Through Technological Stability
Ariatech prioritizes Network Stability and reliability above all else. By providing High-Quality Solutions through a structured development process and expert support system, we maximize telecommunication companies’ Operational Efficiency and cost reduction effects. The savings in infrastructure maintenance costs are reinvested in Technological Advancement and network quality improvement, creating a virtuous cycle that enables carriers to fulfill their Social Responsibility as public service providers. Through this sustainable technological ecosystem, Ariatech underpins the reliable infrastructure development of the AI Era.
ICT Expertise Drives Telecom-Manufacturing Synergy: Radix-MOM
