Our High-Performing Core Network

Fully virtualizable on VMware, K8S, Docker and OpenStack containers

Home Subscriber Server(HSS) / Home Subscriber Register(HLR)

A Home Subscriber Server(HSS) / Home Subscriber Register(HLR) serves as the primary database repository of subscriber information within a LTE/EPC or IMS network core. By centralising all the subscriber information in a single place it allows the signalling to be separated from policy providing a stream lined, high performing network.

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).

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.

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.

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.

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.

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.

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.

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).
