4G LTE core network
YateUCN mixed 2G/4G core network
The YateUCN is a unique, unified core network for GSM/GPRS and LTE. It can be used for building mixed GSM/LTE networks, upgrading GSM networks to LTE, or extending existing LTE networks.
YateUCN software-defined networking
NFV (network function virtualization) implements in software the functions typically performed by hardware components. SDN (software-defined networking) uses the virtualisation technology to split the control plane from the data plane.
The YateUCN ‘beyond SDN approach’ recognizes the usefulness of separating the user and data planes, and implements both in software. The control plane is implemented in the user space for flexibility while the user plane in the kernel space for speed.
YateUCN LTE unified core network
The YateUCN unified core network uses commodity off-the-shelf hardware to offer operators a redundant and cost-effective solution for building or extending LTE networks.
YateUCN LTE unified core network benefits
The YateUCN unified GSM/GPRS/LTE core network server implements all the components and protocols in software. It includes the MSC/VLR/SGSN/GGSN, the MME/SGW/PGW, and the PCSCF/ISCSCF/IWF/BGW for the IMS.
VoLTE
YateUCN scalable VoLTE solution
The YateUCN implements all the functions and protocols from the LTE EPC and the IMS (needed for VoLTE) in software.
The YateUCN is a simplified and scalable solution for LTE, allowing operators to easily add more YateUCN servers or separate the functionality to increase the capacity of their networks.
YateUCN – Back-to-Back User Agent
For SIP signaling, YateUCN acts as a Back-to-Back User Agent server, ensuring a secure transmission of data.
The YateUCN unified core network isolates SIP and RTP call legs between handsets, eliminating the threat of a third party sending additional information through a forged SIP message via the IMS.
4G LTE roaming

4G LTE functions
YateUCN SRVCC
The YateUCN handles SRVCC by performing an inter-MSC handover from 4G LTE to 2G GSM. Built to simultaneously be an MME/MSC and an IMS network for VoLTE, YateUCN performs SRVCC without requiring upgrades to operators’ current deployments.
YateUCN CSFB
CSFB hands a subscriber over from the LTE core network to the circuit-switched core network through the SGs interface during call setup. The SGs interface is added to the LTE architecture and allows mobility management and paging procedures between the MME and the MSC.
YateUCN SMS in LTE
The YateUCN supports IMS MESSAGE, LTE NAS tunneling and CSFB for SMS in the LTE network. Except for CSFB, all the other functions are built-in.

Core network redundancy and load balancing
YateUCN application redundancy
The YateUCN servers provide application-level redundancy.
The YateUCN acts as a cloud, allowing multiple servers to be added to the network, all servers being equal and being able to take over traffic from a failed node.
YateUCN MSC redundancy benefits
The YateUCN replaces the heavy, expensive core network equipment used in conventional networks with small, affordable, and easy-to-manage equipment.
Because it uses commodity hardware, operation and servicing can be managed remotely, with minimal external support and significantly driving operational costs down. The YateUCN provides simplicity and cost-effectiveness to building redundant mobile networks.
YateUCN EPC cloud
A single YateUCN server combines the MME, SGW, PGW, and PCEF functions. A pool of YateUCN servers provide seamless horizontal redundancy, scalability and load balancing in the LTE core network.
YateHSS/HLR cluster
The YateHSS/HLR subscriber server can be configured in a cluster of equal nodes to provide load balancing and application-level redundancy.
2G/2.5G GSM/GPRS core network
YateUCN unified core network
The YateUCN is a unique core network server for GSM (MSC/VLR/GMSC), GPRS (SGSN/GGSN), and LTE (MME/PGW/SGW/PCEF).
YateUCN commodity hardware and generic OS
YateUCN, the unified core network, is a Linux application running on commodity off-the-shelf servers. It implements the functions and protocols for both the GSM/GPRS and the LTE networks.
Subscriber management
YateHSS/HLR subscriber server for GSM, UMTS, LTE networks
The YateHSS/HLR manages subscribers for the GSM, GPRS, UMTS, LTE, IMS, and WiFi networks. Because YateHSS/HLR is a unified solution, users can be located across any network if, for example, they are registered in the LTE network and paging for a CS service is required.
YateHSS/HLR new node synchronization
All the YateHSS/HLR servers hold and manage the same subscriber data. A new YateHSS/HLR node added to the network automatically synchronizes to the data contained in the other servers.
YateHSS/HLR LTE roaming to GSM/UMTS
The YateHSS/HLR is a unified subscriber server for GSM/GPRS/UMTS/LTE networks.
It supports both Diameter and SS7 MAP protocols, allowing users roaming in a 2G /3G network to authenticate to the YateHSS/HLR in their home network over SS7 MAP, in case a Diameter agreement is not yet in place.
