Home Subscriber Server

Home Subscriber Server is ideal for Service Providers evolving their networks to take advantage of new applications and the operational cost savings of IMS/MMD frameworks.

Service Providers are focused on improving average revenue per user (ARPU) by deploying new services quickly and at a price that subscribers will pay. IP multimedia systems (IMS) enables Service Providers to provide differentiated services to their subscriber base and allow subscribers to integrate voice, video, text, content, and presence as part of their service mix, regardless of access technology.

Home Subscriber Server at a Glance

Within an IMS infrastructure, Home Subscriber Server (HSS) is the master repository that maintains information for the authentication, authorization, and establishment of subscriber calls and sessions. This includes support for SIP-based applications such as video sharing; RADIUS interfaces to the PDSN, GGSN, and Has; and Diameter interfaces from SIP applications. In addition, HSS holds significant subscriber profile information, and delivers subscriber information to an application on demand, or as the subscriber information changes.

Features and Benefits

HSS is a key component of IMS/MMD frameworks and offers the following:

• Available as a standalone server that is vendor-independent, allowing it to operate in multi-vendor networks.
• Integrates seamlessly with the Bridgewater Systems AAA Service Controller.
• Provides call and session enablement, service authorization, and authentication across all IP network access types, including wireless, wireline, and broadband.
• Supports RADIUS and Diameter AAA protocols, enabling migration to IMS/MMD.
• Provides a highly scalable solution that is easily expanded as more services are migrated to the IMS platform.
• Redundancy and high reliability ensure five 9's availability.
• Proven interoperability with best-in-class application platforms — Oracle, BEA, Ubiquity.
