NextEPC is a C-language Open Source implementation of the 3GPP Evolved Packet Core, i.e. the core network of an LTE network.

This package provides the PGW or PDN-GW (Packet Data Network Gateway) element of the EPC, i.e. the gateway between the EPC and the external packet data network, such as the public Internet. It implements the S5 interface towards the S-GW, the SGi interface towards the Internet, and the S7 interface towards the PCRF.
