An implementation of the Evolved Packet Core network.

---

Openair-cn is an implementation of the 3GPP specifications concerning the Evolved Packet Core Networks, that means it contains the implementation of the following network elements:

• MME,
• HSS,
• S-GW+P-GW.

Each element implementation has its own repository: this repository (openair-spgwc) is meant for SPGW-C.

openair-spgwc

In the Control User Plane Separation of SPGW, only the SPGW-C (Control Plane) implementation is available in this repo.
