Radiator SIM Module 2.6 released

We are pleased to announce the release 2.6 of Radiator SIM Module. This release includes 3GPP emergency call support and overall enhanced 3GPP AAA Server support, as well as a number of enhancements and bug fixes. 

Customers with valid download access contracts can download updated software packages from our downloads site. Please note that Radiator 4.24 or later and Radiator Carrier Module 1.6 or later are required. 

If you would like to renew your download access contract, or need professional assistance with updating or migrating, please contact and a member of our sales team will be happy to assist.

Revision 2.6 detailed updates and fixes:

  • Invalid APN formats are now rejected early.
  • Included APN match in S6b authorisation checks.
  • Fixed a crash in 3GPP AAA Server triggered by retransmitted messages.
  • Updated identity handling with IMSI encryption based on observed client behaviour.
  • RAT-Type for SWx requests is now set to the value received over SWm defaulting to VIRTUAL. Previously WLAN was always used by 3GPP AAA Server.
  • 3GPP-Charging-Characteristics is now copied to SWm answers when available. Subscription-Id was not added to SWm AAA messages after the user profile was updated by HSS with Push-Profile Request.
  • AAA-Failure-Indication is now sent over SWx to HSS. Previously the VSA was ignored when received from an ePDG.
  • Terminal-Information is now added to SWx requests as required by 29.273 version 13 and later.
  • Enhanced 3GPP AAA Server support to cover 29.273 version 15.4.0. The main behaviour change is S6b triggered PGW registration which is no longer done as often. This was clarified in 29.273 13.4.0 correction CP-160220 CR 0457.
  • Emergency services for authenticated users are now supported by 3GPP AAA Server. Support for emergency services needs to be enabled with a new configuration flag parameter EmergencyServices. When EmergencyServices parameter is set and SQL is used for a session database, one new column and SQL query modifications are needed.
  • Updated 3GPPP AAA Server SWm, SWx and S6b dictionaries for 29.273 version 15.4.0.
  • Crypt::Rijndael is no longer required when Radius::UtilXS release 2.2 or later and Radiator 4.25 or later is installed.
  • 3GPP AAA Server SQL and Redis based session backends no longer trigger unnecessary lookups and SWx deregistration updates when session termination requests are received over SWm or S6b. This can reduce Diameter traffic significantly with certain configurations where lots of clients are not allowed to connect and gateway devices send STRs for these attempts.
  • Removed warnings logged to STDERR by 3GPP AAA Server when processing certain request types. These warnings were harmless but cause unnecessary log entries.
  • 3GPP AAA Server now supports stripping MAC address from NAI format usernames. A new optional configuration parameter StripMACFromUserName controls how this is done.
  • A number of code clean up and maintenance changes were done based on Perl::Critic and other tools.
  • Requires Radiator 4.24 or later and Carrier Module 1.6 or later with 3GPP AAA Server. Radiator 4.24 and later are recommended with plain EAP-SIM, EAP-AKA and EAP-AKA’.
