From HSS to Full Core: Built on Experience. Still Evolving.
Discover how Summa Networks evolved from a trusted HLR/HSS provider into a complete, modular Full Core solution for mobile, IoT and private networks.
For over a decade, HLR/HSS has been at the heart of Summa Networks’ expertise.
As one of the most critical and demanding functions in a mobile network, subscriber management requires reliability, scale and deep technical expertise.
That reputation was earned.
Operators across more than 30 countries have trusted Summa Networks with their subscriber management, including Tier 1 operators. And the HSS remains a key part of what we deliver today.
But we’ve kept building.
In 2025, Summa Networks marked 10 years of building telecom technology. Over that decade, networks changed — and so did the scope of what we deliver.
From HSS expertise to a complete Full Core
Today, Summa Networks delivers a complete, modular Full Core solution.
This isn’t a future vision. It’s what we deliver today.
Our portfolio brings together the network functions operators and new connectivity providers need to build and evolve their networks across 2G, 3G, 4G and 5G.
On the 3G/4G side: HLR/HSS, EIR, PCRF, AAA and SMSC.
On the 5G SA side: UDR, UDM, AUSF, UDSF, PCF, NSSF, SMSF, EIR and NEF.
The portfolio also includes IMS for voice, unified subscriber data management, interworking between network generations and observability across the Core.
It’s the same technology philosophy that made our HSS trusted — carrier-grade, standards-based and designed to avoid vendor lock-in — now extended across a broader Core.
A modular Full Core, built around your needs
The key word is modular.
A Full Core doesn’t mean buying everything at once.
It means starting with what you need today — whether that’s a single network function or a broader Core deployment — and adding capabilities when and where they make sense.
Policy. IMS for VoLTE and VoWiFi. New subscriber management capabilities. The transition towards 5G SA.
The architecture can evolve with your network, without forcing a rip-and-replace approach.
Deploy on-premise, in the cloud or in a hybrid environment. Support different network generations on a single platform. Scale according to your requirements.
Whether you’re an established operator or a new connectivity provider, the Core adapts to your strategy — not the other way around.
Still evolving
Expanding from HSS to Full Core isn’t the end of that evolution.
We’re also evolving how we build and operate our solutions.
AI is becoming part of that journey, helping accelerate development cycles and shorten the time it takes to bring new capabilities to market.
We’re applying AI to enhance development processes, support faster incident resolution and improve operational efficiency — with the goal of reducing friction between an idea, a feature and its deployment.
The result: faster time to feature, more efficient operations and greater flexibility to respond to changing network requirements.
The HSS you know. The Full Core we deliver today.
From our experience building one of the Core’s most critical functions, we’ve expanded into a complete, modular Full Core for mobile, IoT and private networks.
