OPENAIR-CN
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-spgwu-tiny
) is meant for SPGW-U.
In the Control User Plane Separation of SPGW, only the SPGW-U (User Plane) implementation is available in this repo.
It is distributed under OAI Public License V1.1
. See OAI Website for more details.
The text for OAI Public License V1.1
is also available under LICENSE file in the same directory.
The Openair-cn SPGW-U code is written, executed, and tested on UBUNTU server bionic version.
More details on the deployment options and the supported feature set is available on this page.
This source code is managed through a GITHUB, a collaborative development platform
Process is explained in CONTRIBUTING file.
