Optional SIM Authentication Module
The optional SIM Authentication module enables you to provide IP-based services such as public WLAN access, and Unlicensed Mobile Alliance (UMA) and Femtocell access to your subscribers, while leveraging your existing customer care and authentication infrastructure. Appropriate for Global System for Mobile Communications (GSM) infrastructures, the optional SIM authentication module provides AAA services for 802.1X and non-802.1X hotspots and Unlicensed Mobile Access (UMA) networks, enabling several new service offerings. You can offer secure hotspot access via 802.1X and Extensible Authentication Protocol–Subscriber Identity Module (EAP-SIM) or Extensible Authentication Protocol–Authentication and Key Agreement (EAP-AKA) user authentication. Finally, the SIM authentication module extends mobile services over IP access networks for UMA environments, providing the same mobile identity on unlicensed wireless networks as on mobile networks, and enabling roaming and handover between networks.
