Home Subscriber Server Front End
The Ericsson Home Subscriber Server Front End (HSS-FE) fulfils the central role of user data management in Evolved Packet Core (EPC) and IP Multimedia Core Network Subsystems (IMS). HSS-FE holds vital user information (such as identification, location, and profile and security information) and manages subscription-related information in real time for multi-access and multi-domain offerings in an all-IP environment. As specified by 3GPP specifications, HSS-FE supports the network control layer with subscription and session handling, providing capabilities for:
- mobile management
- user security
- user identification handling
- access authorization
- service authorization
- service profiles
Communication services evolution
Improved network and operational efficiency
Improved network and operational efficiency, improving robustness of HSS-FE architecture, simplifying operation and maintenance of HSS-FE architecture, and enabling hardware harmonization across multiple products and vendors
User data exposure
User data exposure, helping to extend UDM capabilities to new business segments together with Service Capability Exposure Function (SCEF) support, enabling new opportunities for different verticals
HSS-FE is built as part of our User Data Consolidation (UDC) solution, decoupling the data storage from the application logic. UDC is the Ericsson Subscriber Data Management solution for every service and every access, moving the focus away from access-oriented subscriber management towards a consolidated handling of user data to enable a wider access and usage of the data.
As the evolution of our HSS SLF (Subscriber Locator Function) product and specially designed with full hardware and software decoupling, HSS-FE enables both native and cloud deployments (that is, as a Virtual Network Function — VNF). (For VNF deployments, different delivery models apply, such as system verification on CEE/BSP 8100 or CEE/HDS8000, certification on VMware or RHOSP, and software-only delivery.)
VNF support helps to reduce CAPEX through hardware harmonization across multiple products and vendors. It also reduces OPEX, leveraging on a smaller footprint, simplified Open Application Model (OAM), and common spare parts management. Thanks to the quicker installation of new UDM network functions, it also improves overall time to market.
