The complete 3GPP core, across both mobile generations.
Deploy a single, converged packet core covering both LTE (4G EPC) and 5G (NSA and SA) with unified subscriber database management and a zero-disruption architectural evolution path.
5G Standalone Core (5GC)
4G Evolved Packet Core (EPC)
One converged core, both generations, every interface.
From UE to internet: control plane, user plane and the 3GPP interfaces we integrate and verify — all inside one hardened Open5GS deployment.
What we engineer on top of upstream Open5GS.
Enterprise Hardened Packaging
Version-pinned, regression-tested core releases fortified with strict security baselines, high-availability cluster setups, and automated Ansible/Helm deployment pipelines for bare metal, Proxmox, or Kubernetes.
Custom 3GPP Development
Features the stock release lacks—custom Diameter/Service-Based charging interfaces, lawful intercept (LI) gateways, network slicing behaviors, and roaming quirks. Engineered cleanly against upstream so you're never stranded on an orphaned fork.
Multi-Vendor RAN & BSS Interop
Verified, field-tested interoperability across multi-vendor eNodeB/gNodeB RAN estates, indoor CPEs, and complex OSS/BSS platforms. We rigorously validate S1, N2, and N3 interfaces before real subscriber traffic hits.
Full-Stack Observability
Production Prometheus and Grafana telemetry built right into the deployment. Track attach rates, bearer establishment latencies, and high-throughput UPF metrics in real time—not inside a vendor black box.
SLA Accountability to 15 Min
Commercial support tiers (Standard, Advanced, Mission-Critical) featuring direct access to named principal engineers and guaranteed 15-minute P1 emergency response times. Compare tiers →
Turnkey Core Operations
Prefer not to manage core operations internally? We run your mobile core end-to-end under SLA—handling proactive monitoring, incident triage, security patching, and capacity scaling.
From compact wireless pods to distributed national cores.
Compact Private Core
The entire EPC/5GC running on a single hardened server appliance or VM—ideal for private wireless LTE/5G networks, enterprise labs, mining sites, and FWA deployments. Live in days, not quarters.
Cloud-Native Operator Core
Containerized network functions running on Kubernetes with horizontally scaling UPFs, zero-downtime rolling upgrades, and cross-datacenter geo-redundancy—engineered for commercial operators and MVNOs carrying revenue traffic.
Distributed MEC / Edge UPF
Deploy high-throughput user plane functions (UPFs) directly at the edge for ultra-low latency local breakout across factories, ports, and smart campuses while keeping the control plane centralized.
Straight engineering answers.
Is Open5GS truly commercial production-grade?
Yes. Open5GS powers live commercial MVNO, private network, and regional broadband infrastructure globally. Srianu provides the critical high-availability clustering, security hardening, and 24×7 commercial SLA that transforms open source into carrier-grade infrastructure.
Are there recurring per-subscriber license taxes?
None at all. Because the core software is open source, you pay zero software license fees regardless of how many SIMs or subscribers you onboard. Your only cost is our engineering, deployment, and SLA support.
How does it integrate with our existing BSS/billing?
We integrate Open5GS with your existing billing, charging, and provisioning systems over standard 3GPP and REST APIs, and provide custom middleware development when proprietary connectors are needed.
