Step-by-Step Overview of Home Subscriber Server in Telecom Systems

The Home Subscriber Server (HSS) is a critical component of modern telecom systems, particularly 4G LTE and IMS networks. It functions as a central database, storing critical information about mobile users such as their identification, subscription information, and security keys. When a user connects to the network, the HSS helps verify their identity and the services they can use, such as calls, data, or VoLTE. It also facilitates roaming by exchanging user data with different networks and ensuring smooth mobility when users move between places.
