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.

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 https://gitea.osmocom.org/osmocom/libosmocore
- libasn1c from https://gitea.osmocom.org/cellular-infrastructure/libasn1c
- libsctp-dev (this is the package name in Debian)
- libosmo-netif from https://gitea.osmocom.org/osmocom/libosmo-netif
- libosmo-sccp from https://gitea.osmocom.org/osmocom/libosmo-sccp
To bootstrap the build, in the root directory, run:
autoreconf --install
After that, run the usual
./configure [options]
make
[sudo] make install
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 https://gitea.osmocom.org/osmocom/asn1c)
- Support for prefixing the generated types (aper-prefix branch of https://gitea.osmocom.org/osmocom/asn1c)
- Then in osmo-iuh.git: make -C src/ regen
