name: HLR
full_form: Home Location Register
context: User Security Settings (GUSS) for service differentiation or GBA_U is desired in combination with HLR or HSS without Zh reference point support, then this can be achieved, for instance by storing the GUSS information in a BSF database (external and/or external to the node itself), or in any other network database which is deemed as appropriate for a specific deployment. GUSS information is not sent over Zh' reference point. If an HLR or an HSS without Zh reference point support is used within the GBA architecture, then the BSF needs to be configured to use the Zh' reference point with that HLR or HSS. If the Zh reference point is available in the HSS and the full migration has happened, then it shall be used between the BSF and the HSS. NOTE 4: If an operator wants to upgrade from a GBA architecture using HLR or HSS without Zh reference point support, to one using HSS with Zh reference point support, then the BSF needs to be configured accordingly to use then the Zh reference point.
description: The Home Location Register (HLR) is a database that stores information about subscribers and their mobile devices in a telecommunications network. It is used for authentication, authorization, and mobility management.
explanation: HLR is classified as a Network Function because it performs essential functions within the telecommunications network, such as managing subscriber data and controlling access to services.
