The GSUP HLR is a stand-alone HLR (Home Location Register) for SIM
and USIM based subscribers which exposes the GSUP protocol towards
its users. OsmoSGSN supports this protocol.
osmo-gsup-hlr is still very simplistic. It is a single-threaded
architecture and uses only sqlite3 tables as back-end. It is suitable
for installations of the scale that OsmoNITB was able to handle. It
also lacks various features like fine-grained control of subscribed
services (like supplementary services).
