name: HSS
full_form: Home Subscriber System
context: An SBI capable BSF performs discovery and selection of an SBI capable HSS. The SBI capable BSF shall utilize the NRF to discover an SBI capable HSS unless the information about SBI capable HSS instance(s) is available by other means, e.g. locally configured on the SBI capable BSF. The HSS selection function in SBI capable BSF entities selects an SBI capable HSS instance based on the available SBI capable HSS instances (obtained from the NRF or locally configured). An SBI capable BSF always selects an SBI capable HSS within its own PLMN. The HSS selection should consider one of the following factors when available to the SBI capable BSF: 1. HSS Group ID of the UE's user identity (IMSI/IMPI or MSISDN/IMPU). 2. IMSI/IMPI; e.g. the SBI capable BSF selects an SBI capable HSS instance based on the IMSI/IMPI range the UE's IMSI/IMPI belongs to, configured locally or based on the results of a discovery procedure with NRF using the UE's IMSI/IMPI as input for HSS discovery. 3. MSISDN/IMPU; e.g.
description: The Home Subscriber Server (HSS) is a network function that stores and manages subscriber data, including user identities, profiles, and service subscriptions. It plays a crucial role in the authentication, authorization, and accounting processes for subscribers accessing network services.
explanation: Based on its responsibilities for subscriber data management, discovery, and selection by other network functions like BSF, the HSS is classified as a Network Function within the telecommunications architecture.
