+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.
+
+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.
+

+
+
+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)
