Steel Belted Radius Carrier 7.0 Administration and Configuration Guide > SIM Authentication Module

SIM Authentication Module

The Steel-Belted Radius Carrier optional SIM authentication module enables Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) service providers to offer wireless network access to subscribers through hotspot concession operators while leveraging existing customer care, roaming, and billing infrastructures. This chapter contains these topics:

• Overview of Components in the SIM Authentication Module
• Overview of Operation
• Overview of Configuration Activities
• Configuring Special Attribute Handling Features (Optional)

The optional SIM authentication module uses the provider SS7 infrastructure to facilitate secure 802.1X-based subscriber authentication and billing. For SIM authentication, a service provider's 802.1X access point (AP) directs authentication requests from user devices to the Steel-Belted Radius Carrier server.

NOTE: Some figures in this chapter may reference both the SIM and SMS authentication modules. This release of Steel-Belted Radius Carrier supports only the SIM authentication module. References to SMS should be ignored.
