set RANAP msgb headroom to 512 (times two) With a headroom of 256, the SGSN crashes with: msgb(0x6e3b90): Not enough headroom msgb_push (256 < 264) I'm not perfectly sure what amount of headroom is strictly necessary. The only reason to pick 512 is that it is twice the amount of 256. Change-Id: I9a193846902a0477af0873f78283c4f2bedaf5dd
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.
The official homepage of the project is https://osmocom.org/projects/osmohnbgw/wiki
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/
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.

It is generally best to check the wiki for the most up-to-date build instructions.
As external library dependencies, you will need
To bootstrap the build, in the root directory, run:
autoreconf --install
After that, run the usual
./configure [options] make [sudo] make install
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.
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:
