Supporting SIM with Signalware


Steel-Belted Radius Carrier support for SIM and other RADIUS protocols that use EAP-SIM or EAP-AKA (such as WiMAX, which may use EAP-AKA), depend on Signalware 9 with Service Pack 6.A software being properly installed on the server.


We strongly recommend that Signalware software be installed and configured before Steel-Belted Radius Carrier is installed because the SBR Carrier installation incorporates Signalware settings, if they are available.

Juniper Networks provides an example Signalware installation with:

  • The correct settings for simple integration with Steel-Belted Radius Carrier.

  • The recommended procedures to configure Signalware 9 to support Steel-Belted Radius Carrier.

  • The recommended procedure for migrating configuration settings forward from an existing Signalware installation.

See SIGTRAN Support for Steel-Belted Radius Carrier.


Because the Signalware communication stack is not supported on Solaris, the SIM authentication module cannot be used on the Solaris platform to communicate with an HLR to process RADIUS requests. However, the module can be used with an HSS by using the RADIUS to Diameter conversion feature.
