Escape punishing per-subscriber licence fees and vendor lock-in. Srianu Technologies packages, hardens, and SLA-supports proven open-source mobile core platforms — and provides the senior telecom engineers who architect and deploy carrier-grade networks from the bare metal up.
We take the world's most robust open-source telecom platforms and deliver them enterprise-ready: packaged, rigorously tested, seamlessly integrated with your RAN and BSS/OSS, and backed by 24×7 SLA support.
Cloud-native EPC and 5GC architecture. Deliver converged 4G/5G data and signaling without artificial subscriber limits or recurring vendor taxes — from single-node edge deployments to distributed Kubernetes clusters.
Explore 4G & 5G Core →Carrier-grade VoLTE, VoNR, and VoWiFi built upon the rock-solid SIP engine that has handled operator voice traffic for over twenty years. Complete P/I/S-CSCF stack, carrier interconnect, and emergency call routing.
Explore IMS & Voice →A pragmatic, highly efficient packet core designed to keep legacy M2M fleets, smart meters, and rural coverage connected reliably while providing a clear, cost-effective migration path to 4G LTE and 5G.
Explore 2G/3G Core →Our fully hosted mobile core as a service for MVNOs, private enterprise networks, and testing labs. Get the hardened Open5GS platform fully deployed, monitored, and operated by Srianu engineers. Currently in closed beta.
Explore nfvi.io →When you need more than just core software packaging, Srianu engineers and delivers complete, carrier-grade network infrastructure — core, BNG routing, IP transit peering, subscriber automation and SLA operations — as a single accountable partner, from the bare metal up.
Architected and deployed carrier-grade BNGs (Broadband Network Gateways), high-throughput IP routing, dynamic transit peering, and subscriber management topologies without proprietary hardware bloat.
Integrated automated subscriber onboarding workflows, RADIUS/AAA authentication, billing hooks, and real-time network telemetry so lean operational teams can scale rapidly.
Backed by Srianu's 24×7 Tier-3 engineering support and continuous monitoring, ensuring carrier-grade uptime and ongoing architectural evolution as bandwidth demands surge.
With VMware renewals jumping 200–300%+, operators are re-platforming production estates to OpenStack — without downtime. We've done exactly that on live, carrier-grade mobile core infrastructure. Two recent migrations off VMware:
Dual-vendor packet-core swap and a full VMware vSphere → OpenStack re-platform on a live Tier-1 UK mobile network — with subscriber service continuity throughout the cutover.
Read the EPC case study →Policy & charging (Gx/Rx/Sy/Sd) migrated to Oracle and re-homed from VMware to OpenStack, integrated with the new core — with no change to the subscriber policy experience.
