FAQ
What is the difference between an HLR and an HSS in a modern network?
While both serve as the central database for subscriber information, the HLR (Home Subscriber Register) is used in 2G/3G legacy networks (SS7-based), while the HSS (Home Subscriber Server) is the primary database for 4G LTE and IMS networks (Diameter-based).
How does a converged HSS/HLR reduce operational complexity?
Instead of maintaining separate databases for 2G, 3G, 4G, and 5G, IPLOOK offers one set of profiles for all. This means a single subscriber identity can seamlessly roam between different network generations without data synchronization issues.
What is the subscriber capacity and scalability of the IPLOOK HSS/HLR?
Our solution is designed to be highly elastic, supporting everything from small-scale deployments of 500 subscribers to massive carrier-grade networks of 10 million+ subscribers.
Does the IPLOOK HSS support 5G migration?
Yes. The platform includes 5G UDM (Unified Data Management) functionality. This ensures that your investment today in 4G LTE infrastructure is future-proofed, as the system already understands 5G NR (New Radio) profiles and can interwork with the 5G Core.
How is subscriber data protected against system failures?
IPLOOK employs a Multi-level Backup Mechanism to ensure 99.999% reliability:
- Level 1: Real-time cache synchronization (2N or N+1 redundancy).
- Level 2: Database 1+1 redundancy mode.
- Level 3: Physical disk-level protection using RAID1.
Can this HSS/HLR be deployed in a cloud-native environment?
Absolutely. Our HSS/HLR is "field-proven" and designed for NFV (Network Functions Virtualization). It can run on bare-metal servers, virtual platforms (VMware/KVM), or private/public cloud environments. This eliminates "vendor lock-in" associated with traditional, proprietary hardware-based HLRs.
Which 3GPP interfaces are supported for multi-vendor interoperability?
The IPLOOK HSS/HLR is 3GPP R14 compliant and supports all standard interfaces for seamless integration:
- S6a: Connecting to the MME (4G).
- Cx: Connecting to the CSCF (IMS/VoLTE).
- Gr/C/D: Connecting to SGSN and MSC (2G/3G).
- Multi-protocol support: Diameter, SS7 (MAP), RADIUS, and modern IT protocols.
How does the HSS/HLR handle subscriber authentication and security?
The system includes a built-in Authentication Center (AuC). It manages sensitive security data such as EPS-AKA, KI, OP, and OPC keys. It also features Admission Control based on access type, ensuring that only authorized devices can register on specific network types (e.g., restricting a certain M2M SIM to LTE only).
