What is EPC? The core network of the LTE System, EPC was introduced by 3GPP in release 8 as a “flat architecture” with the goal of handling data traffic more efficiently from a performance and cost perspective. EPC is offered by Mavenir as a virtualized solution (vEPC). The Mavenir vEPC cloud-based core network architecture is targeted to transform mobile networks through a highly scalable and nimble virtualized Evolved Packet Core (EPC) that can adapt to a range of emerging 4G LTE deployment use cases.
