-%description
-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).

-=== Import Subscriber Data
-
-==== Scripted Import
-
-WARNING: It is not generally a good idea to depend on the HLR database's internal table structure, but in the lack of an
-automated import procedure, this example is provided as an ad-hoc method to aid automated subscriber import. This is not
-guaranteed to remain valid.
-
-NOTE: We may add CSV and other import methods to the `osmo-hlr-db-tool`, but so far that is not implemented. Contact the
-community if you are interested in such a feature being implemented.
-
-NOTE: `sqlite3` is available from your distribution packages or `sqlite.org`.
-
-Currently, probably the easiest way to automatically import subscribers to OsmoHLR is to write out a text file with SQL
-commands per subscriber, and feed that to `sqlite3`, as described below.
-
-A difficulty is to always choose subscriber IDs that are not yet in use. For an initial import, the subscriber ID may be
-incremented per subscriber record. If adding more subscribers to an existing database, it is necessary to choose
-subscriber IDs that are not yet in use. Get the highest ID in use with:
-
----
-sqlite3 hlr.db 'select max(id) from subscriber'
----
-
-A full SQL example of adding a single subscriber with id 23, IMSI 001010123456789, MSISDN 1234, Ki for COMP128v1, and K
-and OPC for Milenage:
-
----
-INSERT subscriber (id, imsi, msisdn) VALUES (23, '001010123456789', '1234');
-
-INSERT INTO auc_2g (subscriber_id, algo_id_2g, ki)
-VALUES(23, 1, '0123456789abcdef0123456789abcdef');
-
-INSERT INTO auc_3g (subscriber_id, algo_id_3g, k, op, opc)
-VALUES(23, 5, '0123456789abcdef0123456789abcdef',NULL,'0123456789abcdef0123456789abcdef');
----
-
-Table entries to `auc_2g` and/or `auc_3g` may be omitted if no such key material is required.
-
-UMTS Milenage auth (on both 2G and 3G RAN) is configured by the `auc_3g` table. `algo_id_3g` must currently always be 5
-(MILENAGE).
-
-The algorithm IDs for `algo_id_2g` and `algo_id_3g` are:
-
-.Algorithm IDs in OsmoHLR's database
-[options="header",width="50%",cols="40%,60%"]
-|===
-|`algo_id_2g` / `algo_id_3g` | Authentication Algorithm
-| 1 | COMP128v1
-| 2 | COMP128v2
-| 3 | COMP128v3
-| 4 | XOR
-| 5 | MILENAGE
-|===
-
-Create an empty HLR database with
-
----
-osmo-hlr-db-tool -l hlr.db create

-
-Repeat above SQL commands per subscriber, incrementing the subscriber ID for each block, then feed the SQL commands for
-the subscribers to be imported to the `sqlite3` command line tool:

-Be aware that the import is lossy, only the IMSI, MSISDN, nam_cs/ps and 2G auth data are set.

-OsmoHLR has an Internal USSD Entity (IUSE) that allows to handle some
-USSD requests internally.  It features a set of simple handlers, which

-
-* `own-msisdn` returns subscriber's MSISDN (if assigned);
-* `own-imsi` returns subscriber's IMSI;
-* `test-idle` keeps the session idle until the MS terminates it, or
-  the guard timer expires (may be useful for testing).
