what is an epc telecom
This article looks at the Evolved Packet Core (EPC), the core network of the LTE system, giving an overview of the architecture of the core network, describing some of its key elements. The EPC is the latest evolution of the 3GPP core network architecture. In GSM, the architecture relies on circuit-switching (CS). This means that circuits are established between the calling and called parties throughout the telecommunication network (radio, core network of the mobile operator, fixed network).
