Home Subscriber Server Front End

Evolved HSS-FE for future proof networks, with support for Network Function Virtualization (NFV) and NB-IoT
The Home Subscriber Server Front End (HSS-FE) fulfils the central role of user data management in the Evolved Packet Core (EPC) and IP Multimedia Core Network Subsystem (IMS). Ericsson HSS-FE holds vital user information such as user identification, location, profile information and security information.

HSS-FE 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 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 profile

To provide this functionality, HSS-FE is built as part of the Ericsson UDC solution decoupling the data storage from the application logic. User Data Consolidation (UDC) is the Ericsson Subscriber Data Management solution for every service and every access. UDC moves the focus away from access-oriented subscriber management towards a consolidated handling of user data, enabling a wider access and usage use of the data, and as well as centralized management. UDC transforms the subscriber data from a cost to an asset, generating revenue for the operator.

HSS-FE is the evolution of the HSS/SLF product and is especially designed with full HW and SW decoupling enabling both native and cloud deployments.
HSS-FE shares a common O&M framework with other different Ericsson applications. HSS-FE can be deployed either as native or as a Virtual Network Function (VNF).
For VNF deployments, different delivery models apply, system verification on BSP 8100 or HDS8000, certified on VmWare or RHOS10 or Software-Only.
VNF support helps to reduce CAPEX through the HW harmonization across multiple products and vendors, and by reducing OPEX leveraging on smaller footprint, simplified OAM and common spare parts management. Thanks to the quicker installation of new UDM network functions it also improves the Time to Market
