The Mobilis Home Subscriber Server (M-HSS) is the heart of all the converged subscriber identity, access and authorization requirements. It is designed to replace an operator’s existing HLR requirements while offering all the multi-profile solutions for SIP-centric IMS networks.

The M-HSS offers a cost effective solution to deploy a flexible infrastructure that can replace a service provider’s existing requirements for subscriber management while providing the flexibility to allow easy transition to an NGN platform without the potential for service disruption. This puts the service provider’s subscribers at the centre of the provider’s strategy for mobility of IMS, UMA and other IP services.

The M-HSS is a software based solution delivered on industry standard hardware. The M-HSS incorporates an IMS Home Subscriber Server (HSS) incorporating the User Mobility Server (UMS) and the Home Location Register (HLR). Full support is provided for all HLR and Authentication Centre (AuC) functionality along with all HSS functionality.

The M-HSS can scale from a few thousand subscribers to many millions on a single platform. Because of the use of an industry standard in-memory database and the advanced caching and replication within the application, performance is deterministic: single figure millisecond response times and hundreds of thousands of transactions per second.
