Hello Harald, can you please explain me how the subscriber location actually work in openbsc. i have seen that you also have a VLR implemented. How does this work? I actually just test the registration and calls in roaming mode. To which part of the Openbsc implementation (program-code) should i refer to for this (subscriber location implementation)?
We don't really have/use any VLR. All we have is a subscriber table, and each subscriber can have a completely different MCC/MNC as part of his IMSI - we simply don't care. There is no distinction between roaming and home network subscribers at all.
All we care about is if the subscriber.authorized field is 0 or 1 in the sql database.
Regarding 'subscriber location' between multiple BTS: We simply store the LAC of where the subscriber was last seen.
