This section describes the configuration parameters of a
<PLMNDatabaseSQL> clause. This clause provides
support for WLAN roaming for EAP-SIM, EAP-AKA and EAP-AKA' by looking up
SCCP layer Peer Global Title, Diameter Destination-Realm and other PLMN
information based on the currently authenticating end user's IMSI. PLMN
information is needed to route the authentication and authorisation
messages to the correct HLR/AuC, HSS or other target that holds the
information for the IMSI.
To enable IMSI to PLMN information lookup, you need to modify Radiator
configuration as follows:
- First define a
<PLMNDatabaseSQL> clause
with an Identifier parameter.
- Then add
PLMNDatabase configuration parameter
in MAP or PeerSP clauses using
the value from step 1.
PLMNDatabase configuration parameter is supported
for SIGTRAN and Diameter but it's not yet available for other
authentication and authorisation methods. For required software versions
and modules, see
Section 2.1. Prerequisites. A
configuration sample is in file
goodies/plmndb.cfg
SQL query for looking up PLMN information and interpretation of the
query results are configurable. The current default value works with the
SQL schema the configuration sample uses.
PeerGlobalTitleHook
runs after PLMN database lookup is done. This allows the hook to access
and modify the looked up information, if needed.
