Anyway: > this is an interesting case. We want to annotate the SMPP message with extra values of from where the SMS came from. This is possible in the osmo-nitb and should probably remain possible. Do you see a way to make this work? I haven't really investigated at all about plugging osmo-bsc back to osmo-cscn with an A-interface, because the focus is so far firmly on IuCS. Worst case we could introduce a "vendor specific" DTAP message sent to the MSC, possibly a feature enabled by a vendor specific BSSMAP message sent by the MSC fist?? (wildly guessing) But I'll start off by enabling SMPP in my build ... :/ > I am really late with this but as part of the bsc_api, I envisioned that we > would have a msc_subscriber_connection if we ever split things up :} Not that late really, I looked at bsc_api briefly but saw that it wasn't helping for IuCS, so I postponed dissecting the (numerous) details of it to another day. It should come naturally when the A-interface is created. But in fact my foggy vision so far is that the struct bsc_api will not actually survive, since the A-interface rx, like IuCS rx, will call functions directly instead of keeping a struct of function pointers... IMHO A clearly structured header file would do a nicer job at highlighting the MSC<->BSC entry points. I am also presuming that we will drop osmo-nitb as such and replace it with "please run osmo-bsc plugged into osmo-cscn", BTW.
