unified LTE/GSM+GPRS core network, including SGSN, GGSN, GMSC, MME, SGW, PGW
YateUCN – Unified Core Network solution
Unified EPC/IMS core network
The YateUCN is a unified core network solution intended for new LTE networks, for upgrading GSM/GPRS networks to LTE or for extending existing 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. The YateUCN also includes the IMS layers for VoLTE – P-CSCF, I/S-CSCF, IWF, and BGW.
It communicates with the LTE eNodeBs over S1AP and GTP protocols and uses a JSON API for configuration and management.
Unified GSM/GPRS core network
The YateUCN also implements the functions and protocols of GSM/GPRS core networks. In GSM/GPRS, the YateUCN acts as a SGSN/GGSN/GMSC in a single server.
Remote access for operations and management
YateUCN is easy to operate and manage remotely using the Yate Mobile Management Interface (MMI) online. The interface makes it accessible to add a new YateUCN unit, to setup a cluster of YateUCNs, to configure a single YateUCN function (GMSC, SGSN, GGSN, SGW or PGW), to configure YateUCN equipment with all its GSM/GPRS/LTE functions and more. With YateMMI operators can remotely manage their entire network equipment using a single web interface.
Features and benefits
- 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.
