Unified Core Network solution for GSM/3G/LTE and 5G SA/NSA

Unified 5G/EPC core network

The YateUCN5G is a unified core network solution intended for new 5G SA / NSA networks combined with LTE networks.

The YateUCN software-defined core implements all the functions and protocols of the LTE core network in software, and uses commodity hardware. It integrates the EPC layers MME, S-GW, P-GW, and PCEF.

It communicates with the 5G gNodeB using NGAP/GTP and LTE eNodeB over S1AP/GTP protocols and uses a JSON API for configuration and management.

Remote access for operations and management

YateUCN5G is easy to operate and manage remotely using the Yate Mobile Management Interface (MMI) online. The interface makes it accessible to add a new YateUCN5G unit, to setup a cluster of YateUCN5Gs, to configure a single YateUCN5G function (SGW, PGW, SMF, AMF, UPF, SMSF), to configure YateUCN5G equipment with all its 5G SA/5G NSA/LTE functions and more. With YateMMI operators can remotely manage their entire network equipment using a single web interface.

Features and benefits

  • The YateUCN runs on commodity hardware, allowing for a simplified network architecture and lower deployment costs
  • Enables carriers to deploy LTE networks with reduced initial investment.
  • Allows for scaling as you go. You can add more servers or separate the functionality as more users adopt your service.
  • Increases network resiliency; in case of equipment failure you can easily configure another server to take up the functions of the fault node.
  • Has low idle traffic, which allows transport technologies like satellite
