Dear Neels, Thank you very much for the links.

The thing that made me confused at first is the linked list (g_lu_ops) which contains lu_operations. But it seems I am gradually beginning to understand what is going on. Currently, I am compiling Osmocom-BB to test all the stuff with Virtual Um. I am going to set a few breakpoints in OsmoHLR to see how it goes :) > Why are you particularly interested in the HLR? We are going to write a simple proxy which converts from GSUP to MAP and vice versa. While that is not going to be easy, we have enough time and motivation for that. King regards, Mykola
