IP Multimedia Subsystem (IMS) AAA Server
- Carrier-grade multiprotocol Diameter- and RADIUS-based AAA server
- Supports: 3GPP I-WLAN and IMS based femtocell support
- IMS-based authentication, authorization, and accounting against an HSS subscriber store
Overview
The advanced IP Multimedia Subsystem (IMS) AAA Server enables 2G/3G GSM/UMTS (Global System for Mobile Communications/Universal Mobile Telecommunications System) mobile operators to support 3GPP WLAN services, including UMA (Unlicensed Mobile Access), femtocell- and IMS-based I-WLAN.
The IMS AAA server performs SIM-based (Subscriber Identity Module) authentication, subscription authorization, and accounting (AAA) in 3GPP WLAN interworking environments where the primary subscriber database is a Home Subscriber Server (HSS). This flexible support allows the IMS AAA server to provide a cutting-edge access solution that supports service providers' evolution toward advanced IMS-based networks and the lucrative new revenue opportunities they promise.
Features
The IMS AAA Server performs authentication of subscriber requests from RADIUS and Diameter WLAN ANs, using either the EAP-SIM (Extensible Authentication Protocol-Subscriber Identity Module) or EAP-AKA (Extensible Authentication Protocol-Authentication and Key Agreement) protocol. After successful authentication, authorization is performed, resulting in the return of policy information to the WLAN AN to provision the session. Subscriber access is provided only to the local IP network such as the Internet or Intranet directly from the WLAN AN.
- Supports WLAN 3GPP IP access services: The WLAN 3GPP IP access service allows authorized subscribers to access packet switched (PS) services in the 3GPP IMS service plane through a secure tunnel. IP traffic is tunneled to the 3GPP IMS network via a WLAN Access Gateway (WAG) and the PDG. Multiple tunnels can be authorized for previously authenticated subscribers, allowing access to any number of services simultaneously.
- Supports femtocell technology enabling Fixed Mobile Convergence: Femtocell technology extends cellular service into residential and small business environments where access is often limited. When you're at home or the office, network access is through the femtocell access point and the broadband connection. Subscribers benefit from reduced in-home call charges, improved coverage (since the base station is locally accessible), and continued use of a current handset. For mobile operators, femtocell reduces cell tower usage, increasing capacity and reducing cost to address the FMC market in a cost-effective manner.
Diameter Base Platform Kit
Juniper Networks Diameter Base Platform is a 3GPP IMS-compliant development kit that allows developers to implement arbitrary Diameter applications, reducing development costs and time-to-market. More than just an implementation of the Diameter Base Protocol, it maintains connections to Diameter peers, manages traffic flow, detects anomalous conditions, and allows your application code to direct its operation when your application developers require it.
