| Osmocom Iuh experimentation 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 |
| |
| 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 |
| |
| h1. Using |
| |
| Note: osmo-iuh is in active development (December 2015, January 2016) so below |
| statements may outdate rapidly. |
| |
| 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-REGISTER-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) |
