Osmocom Iuh expermientation code
(C) 2015 by Harald Welte <>
This code is a playground for implementing something along the lines of
the an Iuh interface of a HNB-GW. The intent is to later integrate this
with OsmoNITB + OsmoSGSN, in order to have 3G capable 'network in the
h1. Building
Just go to the 'src/' directory and type make. As external library
dependencies, you will need
* libosmocore from git://
* libasn1c from git://
h1. Using
there's not much to use yet. But if you run the 'hnbgw' executable,
it will open a listening SCTP socket and wait for incoming Iuh
connections. It will accept any HNB-REGITER-REQUEST, so the homeNodeB
should start to establish RUA and RANAP (which we haven't implemented
h1. 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://
* support for prefixing the generated types (aper-prefix branch of
