Description

Hello developers,the osmo-HNBGW works great with the 3GPP standard femtocells which implemented the HNBAP&RUA protocol,thank you very much,but as Welte said it's somehow dfficult to find some not "lock-down" hNodeB devices,such devices like the ip.access nano3g s8 is really hard to get one even not care about the price nowadays,but the Huawei's old brother ePico3801B variant is somehow easy to get one from some online platform with pretty reasonable price.

I know you guys may not want to waste time on some proprietary blobs that even hard to get one in Europe,but after some reverse-engineering work and according to datasheet from Huawei,it showed that the RUA was replaced with SPUA,and the HNBAP was replaced with APM protocol.And it seems likes Huawei used the commercial NodeB source code and add some sccp-proxy to convert the standard SCCP signaling into SPUA protocol which possible actually implemented the RUA protocol(rua.c source file compiled),and the structure of SPUA signaling is somehow similar with the RUA signaling types,but the APM protocol is completely different compare to the simple HNBAP protocol.
All in all,it will be pretty nice to support these protocols,if anyone need some hardware to analyse,i can send one for free,:)
