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](https://osmocom.org/) Open Source Mobile
|
|
|
|
|
Communications project.

|
|
|
|

|
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.

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)
|
2021-10-22 21:19:06 +00:00
|
|
|
* Support for prefixing the generated types (aper-prefix branch of
|
2017-03-17 17:15:20 +00:00
|
|
|
git://git.osmocom.org/asn1c)
|
2021-10-22 21:19:06 +00:00
|
|
|
* Then in osmo-iuh.git: make -C src/ regen
