Private Network Solutions
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.

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.
