Hi all,
I was thinking about how to deal with the so called "evil twins" in the
distributed hlr, and also how to have a subscriber-create-on-demand
situation at the same time as a having an mslookup client.
The problem being that if we have mslookup client + fallback to
create-on-demand if no HLR responds for an IMSI, we will eventually
create a duplicate because the HLR that owns the IMSI is not contactable
at the time of an IMSI ATTACH attempt.
Anyway, just in terms of investigating the situation on my HLRs, I added
features [1] - so far, an ability to do a gsup.hlr lookup and not exit
on the first age:0 - so that I can see all HLRs that respond as having
the imsi in local HLR, and also to ask via mDNS for HLRs that have an
IMSI, but only if it's active on that HLR, that is, it has nam_cs/nam_ps
So this is really asking about what people feel about expanding the
D-GSM features in osmo-hlr, as I think it may be the case that
rhizomatica/TIC are the only people that use it?
