Investigate #LMDB as HLR storage
https://projects.osmocom.org/issues/3649

This Open Source Mobile Comm project appears to be an open source impl of a 3G network's backend software. But they're not using the standard 3GPP protocols, they're using their own home-grown stuff instead.

Looks like a toy, using SQLite3 as its HLR storage. Real 3G/4G networks use LDAP, lots of OpenLDAP in particular because nothing else scales enough, efficiently enough.
