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.
To summarize the point, the LTE EPC:
To better understand the concept of Evolved Packet Core, you need to have a clear image of its nodes and how each of them work.
The sections below describes the LTE EPC architecture and the role of each component, as well as the our EPC solution equipment.
We provide two types of LTE EPC solution:
- MiniCore – EPC for test and research
- YateUCN and YateHSS/HLR – EPC for full production equipment
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 - the LTE EPC solution
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.
Minicore - LTE EPC for Test and Research
The Minicore is a small computer that comes with all the LTE EPC nodes fully installed. It contains the HSS/HLR, MME, SGW, PGW as a part of the EPC. In addition to that the MiniCore also has the SMSC and the STP included. 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.
