what is home subscriber server

The Home Subscriber Server (HSS) is a crucial component of a telecommunication network that stores and manages subscriber information, such as phone numbers and authentication credentials. It is responsible for authenticating and authorizing the access of subscribers to the network services. In simpler terms, the HSS is like the home address book for mobile network operators. It’s where all the important details are kept, and without it, you wouldn’t be able to make calls, send text messages or use the internet on your mobile device.
