Evolved Packet Core (LTE EPC)
What is EPC in LTE ?
The EPC represents the Core of an LTE network. It is formed by multiple nodes, the main ones being MME, SGW, PGW and HSS. This nodes offer multiple functionality like mobility management, authentication, session management, setting up bearers and application of different Quality of Services.
The LTE Core Network Architecture has the following nodes:
Note as well that all the nodes mentioned above communicate with each other through Diameter and GTP, as a part of the LTE EPC architecture.
The relevance of Quality of Service (QoS) to operators and users
There are many benefits of using the LTE core network, such as Quality of Service.
Yate-based LTE EPC solutions for operators - highly scalable and suitable for any operator size and structure, private networks included.
We provide the following Evolved Packet Core products:
YateHSS/HLR as a solution for HSS/HLR:
Our solution doesn’t require the use of any special hardware since our YateHSS/HLR is software on Linux machine. It is scalable because you are able to add more nodes as your needs increase and the nodes are kept in sync through clustering. Our solution also provides functionality for HLR and AUC functionality for 2G, 3G, and even WiFi networks, not only for LTE Core Network (HSS, Diameter Based)
YateUCN (Unified Core Network) is our solution that provides maximum functionality for all the other Evolved Packet Core nodes in a single server: Our solution comprises the MME, SGW, PGW, and PCEF nodes. It is very flexible and can communicate with HSS via 2G/3G protocols or 4G protocols. This is the most complex product we developed. Having all of these functions in one machine decreases the need for setting up extra machines for each node. Our YateUCN is a software-based solution and it requires only an installation procedure on a Linux machine. System configuration is simple through the Mobile Management Interface and it can be accessed remotely. Our system also provides 2G core network functionality.
YateUCN is a high capacity unified core network solution intended for new LTE networks, for upgrading GSM/GPRS networks to LTE EPC or for extending existing LTE networks.
LTE Core Network for Test - The Minicore
The Minicore is a small computer that comes with YateHSS and YateUCN fully installed. It also contains YateSMSC (for SMS services), YateSTP (for SS7 routing), YateDRA (for Diameter routing) and YateMMI (the configuration interface for all the other equipment). Having all these technologies on a single machine provides a simple solution for setting up and testing how mobile networks work. Our LTE core netwotk test equipment helps in capturing traffic between nodes to help you understand mobile procedures as well as experimenting with both 2G and 4G networks – Setup, and Routing.
