The platform
Ouroboros builds the mobile core network software that runs inside operator networks — from 2G through 5G, on a single platform called AMTP (Advanced Multimedia Telecom Platform).
Every core element is native to the platform: HLR, HSS, OCS, PCRF, SMSC, MME, and the full 5G Standalone suite. One vendor, one platform, one support team, with a tailored SLA.
Deployable on bare metal, VMware, Kubernetes, or cloud. You choose the infrastructure.
Standards-compliant and production-ready — delivered as native modules on one platform, not a patchwork of acquired stacks.
Core Solutions
Pre-integrated telecom packages for operators who need to launch, modernise, or scale without rebuilding from scratch.
The complete mobile core stack, from 2G through 5G, on one platform. One vendor, one deployment, one support contract across every network generation, with a tailored SLA.
