Our High-Performing Core Network
Fully virtualizable on VMware, K8S, Docker and OpenStack containers
Unified Data Management(UDM) / Authentication Server Function(AUSF)
UDM: The same as 4G’ s HSS (Home Subscriber Services), UDM is a centralized way to process network user data in 5G through Nudm interfaces to provide services for AMF, SMF, SMSF, AUSF, NEF and GMLC. It also provides services such as authorization of accessing, registration, uninterrupted services.
AUSF: As a major part of 5GC to facilitate security processes, AUSF performs the authentication function of identifying UEs and storing authentication keys.

FAQ
What are the primary roles of UDM and AUSF in a 5G network?
UDM (Unified Data Management): Functions similarly to the 4G HSS. It is a centralized repository for processing network user data, providing services like access authorization, registration, and session continuity.
AUSF (Authentication Server Function): Acts as the security hub of the 5GC. It performs the authentication process to identify User Equipment (UE) and securely stores authentication keys.
How does the 5G UDM differ from the 4G HSS?
While both manage subscriber data, the 5G UDM is designed with a cloud-native approach. It uses service-based interfaces (SBI) like the Nudm interface to communicate with other network functions (AMF, SMF, etc.), whereas the 4G HSS typically relies on Diameter-based protocols.
What is "Converged Data Management" in the context of IPLOOK’s solution?
IPLOOK’s solution offers a converged platform that integrates the functionality of 2G/3G HLR, 4G EPC-HSS, IMS-HSS, and 5G UDM. This allows operators to manage user data across multiple generations of mobile networks (2G through 5G) within a single, unified system.
Which authentication protocols are supported by the AUSF?
The AUSF supports industry-standard security protocols to ensure secure access to the network, specifically:
5G AKA (Authentication and Key Agreement)
EPS-AKA (for interworking and legacy compatibility)
What are the key interfaces supported by UDM/AUSF?
The system supports a wide array of 3GPP-standard interfaces and management protocols, including:
Service Interfaces: N8, N10, N13, N16, N21, and N52.
Northbound Interfaces: RESTful APIs for easy integration with external systems.
Management Protocols: MML, SNMP, CLI, and SSH.
How does the system handle security and protection against attacks?
Beyond standard authentication, the platform includes:
DDoS Attack Proofing: To ensure service availability under heavy malicious traffic.
Enhanced Linux OS Security: Hardened operating system environment.
Personal Data Protection: Features to ensure subscriber privacy and data integrity.
Can the UDM/AUSF be deployed in a virtualized or cloud environment?
Yes. The solution is designed for modern infrastructure and can be deployed on:
What features are included for Subscriber Data Management?
The UDM provides comprehensive subscriber-related functions, such as:
User Profile downloading and updates.
Mobility management and ME (Mobile Equipment) identity checks.
NIDD (Non-IP Data Delivery) authorization.
Online subscriber statistics and parameter provisioning.
Does the solution support a smooth migration from 4G to 5G?
Yes. The platform is built to support a smooth evolution from 4G EPC HSS to 5GC UDM/AUSF. It allows for the seamless migration of full user data to the cloud-based 5G system, protecting the operator's existing investment while enabling new 5G services.
How is the O&M (Operation and Maintenance) managed for these functions?
Operators can manage the UDM/AUSF through a graphical web-based management interface or a command-line interface (CLI). Key O&M features include:
KPI Management: Monitoring network performance indicators.
Fault & Log Management: Real-time troubleshooting and historical analysis.
Configuration & License Management: Flexible system adjustments and scaling.
