The Accept incudes the IMSI that the phone presented, but somehow we fail to encode the Context ID as bitstring, see ../pcap/20150911-hnbap-ue_register.pcap |

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)
