Harald Welte 50a0675cde Fix license headers: Should have been AGPLv3+, not GPLv2+
I'm not sure why one files (written by Philipp)
did contain a GPLv2+ header, instead of the AGPLv3+ which is the
actual overall project license.  I consider it a mistake.

In any case, any copyrightable contribution to those files was done by
sysmocom employees, so I as managing directory can legally make a
license change, whther or not it was a mistake early on or not.

osmo-iuh - Osmocom Iuh implementation

This repository contains a C-language implementation of the 3GPP Iuh interface. You can use it to interface Iuh-speaking femtocells/small cells to Iu-speaking MSCs and SGSNs.

It is part of the Osmocom Open Source Mobile Communications project.


The official homepage of the project is https://osmocom.org/projects/osmohnbgw/wiki

GIT Repository

You can clone from the official libosmocore.git repository using

git clone https://gitea.osmocom.org/cellular-infrastructure/osmo-iuh

There is a web interface at https://gitea.osmocom.org/cellular-infrastructure/osmo-iuh


There is currently no documentation beyond the wiki available on the homepage. We would love to see somebody contributing a manual that can be part of the osmo-gsm-manuals suite.
