Unified EPC/IMS core network
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 (e.g. Dell PowerEdge R430).
YateUCN integrates the EPC layers – MME, PGW, SGW, and PCEF and also includes the IMS layers for VoLTE – PCSCF, ISCSCF, IWF, and BGW.
It communicates with the LTE eNodeB module over S1AP and GTP protocols and uses a JSON API for configuration and management.
Supported Codecs
YateUCN only supports the following codecs of the ITU-T standard, G.711 [also titled as Pulse code modulation (PCM) of voice frequencies]:
- A-law (PCMA, G.711A)
- μ-law (PCMU, G.711U)
