It was found in the field that some peers sends an X.213 IP address consisting of 7 bytes (1byte IDP/AFI, 2byte ICP, 4 byte IPv4 address) insetad of 20 bytes. This is indeed possible when reading ITU Rec X.213 A.5.2.3, where it states that Table A5 defining the 17 bytes DSP len for IANA ICP "gives the maximum length of the DSP". So smaller values are still possible/acceptable. Related: SYS#6623 Change-Id: I507fb1605d976bd8573162e4fa81721245330184 |

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