Evolved Packet Core(Epc)

Evolved Packet Core (EPC) is an innovation which depends on GSM/EDGE and UMTS/HSPA technologies, can increase the capacity and speed using a different radio interface together with core network improvements. EPC refers to a core network architecture that aggregates access networks including LTE, 3G or 2G.   The virtual EPC(vEPC) is a complete LTE packet core solution based on network functions virtualization (NFV) technology. The vEPC can shorten the new service time to market, build an open ecosystem, and stimulate service innovation.
