Osmocom Iuh expermientation code
|
||||||
|
(C) 2015 by Harald Welte <laforge@gnumonks.org>
|
||||||
|
|
||||||
|
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
|
||||||
|
box'.
|
||||||
|
|
||||||
|
h1. Building
|
||||||
|
|
||||||
|
Just go to the 'src/' directory and type make. As external library
|
||||||
|
dependencies, you will need
|
||||||
|
* libosmocore from git://git.osmocom.org/libosmocore
|
||||||
|
* libasn1c from git://git.osmocom.org/libasn1c
|
||||||
|
|
||||||
|
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
|
||||||
|
yet).
|
||||||
|
|
||||||
|
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://git.osmocom.org/asn1c)
|
||||||
|
* support for prefixing the generated types (aper-prefix branch of
|
||||||
|
git://git.osmocom.org/asn1c)
