Bridgewater Systems Solutions for Fixed-Mobile Convergence
The Bridgewater Systems™ Subscriber Management and Authentication solution bundles robust 3GPP AAA functionality with IP address management and session state streaming to offer comprehensive support of IP services in fixed-mobile deployment architectures.
At the core of the solution, the Bridgewater Systems AAA Service Controller provides a platform to enable the quick delivery of advanced services across multiple networks. Built around a powerful policy and profile engine, the solution allows Service Providers to offer and control access to advanced and differentiated services across all access types and infrastructures: GSM, UMTS, CDMA, Wi-Fi, WiMAX, DSL, Cable, and, ultimately, IMS frameworks.
Solution benefits
- Scalable high-performance network access control via AAA services.
- 3GPP standards-compliant for ease of interoperability and improved time-to-market in multi-vendor and multi-access technology networks.
- Centralized subscriber data management enables flexible and comprehensive subscriber and service policy management over multiple networks simultaneously.
- Real-time repository provides dynamic awareness of subscriber session context information.
- EAP SIM/AKA based authentication and authorization for voice and data calls via a MAP/Diameter interface with the HLR/HSS to ensure interoperability with legacy authentication systems and seamless authentication between the cellular and WLAN access networks.
- Fast re-authentication for reduced authentication load on the HLR and lower latency in end-to-end-call flows.
- Vector caching reduces message flow and increases performance by caching multiple vectors on initial authentication request.
- Native support of Diameter and RADIUS provides for evolutionary network development.
- RADIUS-based dynamic assignment of IP addresses with very little latency to improve overall scalability of the network, and subscribers’ quality of experience.
- Session streaming segments a single incoming RADIUS accounting stream into multiple outbound streams of information tailored to the individual destination application, for optimized network utilization.
- Modular approach allows incremental deployment of functionality to scale to support business and service growth.
The Bridgewater solution features the following components:
- AAA Service Controller
- IP Address Management
- Session State Streaming
The key elements of this solution support subscriber management and authentication services in FMC deployments. The AAA Service Controller provides core network access control functions, and the Data Streaming Server provides intelligent streaming of session records to applications. (click to enlarge)
