Evolved Packet Core
The EPC also provides the capability for the integration of wireless with wireline and other alternative networks to enable IP-based communications and services over both wireless and wireline networks.
The EPC provides a common subscriber anchor for mobility, billing, policy, and charging. The three core elements of the EPC are the Mobility Management Entity (MME), Serving Gateway (SGW), and Packet Data Network Gateway (PGW). The schematics shown in Figure 1 and Figure 2 provide a simplified view of the virtual EPC (vEPC) architecture and topology.
SilatTech packet core provides key components needed for a Telco-Grade evolved packet core (EPC) and 5G core system (5GC). It’s well suited for multi-cloud environments. It is also infrastructure agnostic and independent of the underlying cloud infrastructure used for orchestration, lifecycle management (LCM), and infrastructure resource management.
SilatTech EPC provides enhanced service control, and advanced provisioning and ensures efficient use of network resources.
SilatTech EPC components provide the functionality of access control, packet routing and transfer, mobility management, security, radio resource, and network management.
SilatTech EPC is a set of solutions consisting of MME, SGW (Serving GW), PDN GW/GGSN, and optionally HLR/HSS and PCRF components, or any combination of these, providing a fully functional solution. Each of the solutions may be deployed either separately or as a part of the turn-key bundle whereas several nodes may work in the load-sharing mode which makes SilatTech EPC suitable for a wide range of mobile operators having different subscriber bases and network topologies.
