Bug #2857
closed
No automatic testing of IuPS interface
Added by laforge over 6 years ago.
Updated over 4 years ago.
Description
Similar to the situation in OsmoMSC with IuCS, we don't have any automatic testing of the IuPS interface. Once we figured out how to properly interface RANAP from TITAN, we should be able to write test cases in TTCN-3 to automatically test our IuPS implementation.

I have RANAP encoding/decoding now working in TTCN-3, and I've also created a set of RANAP templates to use. Integration into the SGSN tets suite is currently ongoing.
- Status changed from In Progress to Stalled
The core RANAP integration, the templates etc. appear to be working. The problem is that due to bugs in the proprietary asn1 compiler we're not able to reliably transcode between BER and APER at this point. setting to stalled again.
the transcoding issues have long been resolved, as can be seen wen looking at IuCS related tests that are already in production.
The "problem" now with IuPS is that for the Gb/BSSAP based SGSN tests we don't have the notion of a (sccp or otherwise) connection between the RAN and the SGSN. LLC messages are simply exchanged "stateless" over BSSGP. For IuPS,this needs to chang substantially, so it's much hader to have "portable" test logic that works over both a 2G and a 3G RAN.
latest code is in laforge/iu

branch has meanwhile been merged AFAIR, but I don't see any Iu tests as part of SGSN_Tests.ttcn executed yet?
