osmo-iuh - Osmocom Iuh and HNB-GW implementation

This repository contains a C-language implementation of the 3GPP Iuh interface, together with a HNB-GW (Home NodeB Gateway). 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.

Homepage

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 git://git.osmocom.org/osmo-iuh.git

There is a cgit interface at http://git.osmocom.org/osmo-iuh/

Documentation

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.

Mailing List

Discussions related to osmo-iuh are happening on the openbsc@lists.osmocom.org mailing list, please see https://lists.osmocom.org/mailman/listinfo/openbsc for subscription options and the list archive.

Building

It is generally best to check the wiki for the most up-to-date build instructions.

As external library dependencies, you will need

  • libosmocore from git://git.osmocom.org/libosmocore
  • libasn1c from git://git.osmocom.org/libasn1c
  • libsctp-dev (this is the package name in Debian)
  • libosmo-netif from git://git.osmocom.org/libosmo-netif (sysmocom/sctp branch)
  • libosmo-sccp from git://git.osmocom.org/libosmo-sccp (sysmocom/iu branch)

To bootstrap the build, in the root directory, run:

autoreconf --install

After that, run the usual

./configure [options]
make
[sudo] make install

Using

Note: osmo-iuh just left very active development (December 2015, January 2016), so your mileage may vary.

If you run the 'hnbgw' executable, it will open a listening SCTP socket and wait for incoming Iuh connections. It will accept any HNB-REGISTER-REQUEST, and it will establish Iu (over SUA) connections towards the MSC and SGSN.

Regenerating C code from ASN.1 source

In order to re-generate the C source code from the ASN.1 source, you will need a modified asn1c which has the following features:

  • APER support (the patch from Eurecom, or its forward-ported version from the aper branch of git://git.osmocom.org/asn1c)
  • support for prefixing the generated types (aper-prefix branch of git://git.osmocom.org/asn1c)
