YateUCN is a unified core network solution intended for new GSM/LTE networks, upgrading GSM networks to LTE or for extending existing networks.

YateUCN software-defined core implements all the functions and protocols of GSM and LTE core networks in software, and uses commodity hardware. YateUCN integrates the MSC/VLR/SGSN/GGSN and GMSC nodes from the GSM/GPRS core network and the SAE/VoLTE layers from the 4G LTE network in a single server.

The unified core network solution is based on replacing the base station subsystem with YateBTS (GSM) and the eNodeB with YateENB (LTE). YateUCN communicates with YateBTS/YateENB using the SIP/S1AP/GTP protocols, instead of the more costly SS7 MAP-A interface (BSSAP protocol). This leads to a higher return on investment without affecting the reliability of the network or the provided services.

YateUCN uses a JSON API for configuration and management.
Features and benefits
YateUCN runs on commodity servers, allowing for a simplified network architecture and lower deployment costs.

Enables carriers to deploy 4G 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.

SIP protocol establishes connection between YateUCN and YateBTS, allowing SatSite base station to communicate with any YateUCN in the network. No BSC is needed between YateBTS-powered SatSite and YateUCN.

Has low idle traffic, which allows using transport technologies like satellite.
