What is Home Subscriber Server?
The Home Subscriber Server is the master user database that supports the IMS network entities that handle the calls/sessions. It contains user profiles, performs authentication and authorization of the user, and can provide information about the physical location of user. It’s similar to the GSM Home Location Register.
Is HSS part of EPc?
In this figure, the EPC is composed of four network elements: the Serving Gateway (Serving GW), the PDN Gateway (PDN GW), the MME and the HSS.
What is HSS in LTE?

What is Ericsson HSS?
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).
Why is IMS needed?
IMS, or IP Multimedia Subsystem, is often touted as a must-have network evolution for mobile operators that want to derive value from future applications. The goal of IMS is to replace the operator’s current back-end network architecture with an all IP-based system making it easier to deploy applications.
What is the role of the home subscriber service HSS in 4G 5g cellular architecture?
HSS (Home Subscriber Server) – is the unit that manages user profiles, subscriptions and security functions. HSS is responsible for e.g. user authentication when trying to connect to the network and authorization of access to selected services.
What does E stands for in eNodeB?
eNodeB often abbreviated as eNB stands for Evolved Node B and it is the radio base station in 4G LTE networks. eNodeB is an essential part of the 4G LTE radio network (E-UTRAN) and is capable of performing network control functions in addition to creating mobile network coverage.
What is SGW and PGW in LTE?
MME stands for Mobility Management Entity, PGW stands for PDN gateway and SGW stands for Serving Gateway. The figure depicts LTE EPS architecture. In the figure, UE refers to User Equipment. It is the mobile phone device used to access the LTE network.
What is SLF in 5g?
The subscriber location function, or SLF is a function within an IP multimedia subsystem that provides information about the home subscriber server (HSS) that is associated with a particular user profile. It is generally implemented using a database.
What is Ericsson CUDB?
Laying in the heart of Ericsson’s Data Management solution, the Centralized User Database (CUDB) is a flexible high-capacity, highly robust and high-performance database that consolidates subscriber profile data from all users and IoT devices in the network.
