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)
