Description

3GPP TS 48.016 Section 6.2 specifies the "IP Sub-Network Service Protocol" (SNS), which can be used to auto-configure the NS-VCs and their IP addresses/ports between one NSE and the SGSN.

We don't implement this so far, as the spec states that this is an optional protocol and that NS-VCs may also be configured statically.

patches now have a rather full TTCN3 test suite (at least for the successful cases) and implement all of the SNS procedures (SIZE, CONFIG, ADD, DELETE, CHANGE_WEIGHT).

They're now in review and I expect them to be merged rather soon.

OsmoPCU requires a "gb-dialect ip-sns" vty/config statement to use the IP SNS and not the classic dialect.
