OsmoNITB Migration Guide¶
Historically, Osmocom offered the OsmoNITB "Network-In-The-Box" as an actual single program. It was a useful simplification at the time, but in 2017, Osmocom have decided to split OsmoNITB into programs more closely resembling traditional network architecture. It is recommended to use the new separate components instead of the OsmoNITB, since active development focus has moved there.
Creating a new Network In The Box from scratch is described at Osmocom Network In The Box, please refer to that page to complement the descriptions found here.
This page aims at describing the steps necessary to move from a working operation of osmo-nitb to the new split components.
With OsmoHLR comes
osmo-hlr-db-tool, which is capable of importing the most important subscriber data from a database that was used with OsmoNITB.
In a standard installation, the osmo-nitb database should be found at
/var/lib/osmocom/hlr.sqlite3, and the osmo-hlr database is expected at
/var/lib/osmocom/hlr.db. Hence the migration command becomes:
osmo-hlr-db-tool -l /var/lib/osmocom/hlr.db -n /var/lib/osmocom/hlr.sqlite3
-l is passed,
./hlr.db is assumed.
If the target
hlr.db does not exist yet, it is created.
Note that not all information is copied to the hlr.db, just IMSI and 2G auth tokens.
To avoid future confusion, it may be desirable to remove the legacy hlr.sqlite3 from the system (i.e. backup to somewhere else), or rename it to something like
osmo-nitb.db, so that it is not mistaken for the OsmoHLR database.
Most of the current OsmoNITB config options still exist, but are now moved to OsmoMSC or OsmoBSC. Few are required in both.
