name: VLR
full_form: Visitor Location Register
context: The VLR (equivalently the SGSN) shall support the UMTS conventional mechanism for user identity confidentiality described in 6.1 of 3G TS 33.102. The VLR shall store the following data elements: - TMUI-CS: a temporary identity allocated by the CS core network; - LAI: a location area identifier; Table 14: VLR â User Identity Confidentiality â Data elements Equivalently, the SGSN shall store the following data elements: - TMUI-PS: a temporary identity allocated by the PS core network; - RAI: a routing area identifier. Table 15: SGSN â User Identity Confidentiality â Data elements
description: The Visitor Location Register (VLR) is a network function responsible for storing and managing user identity confidentiality data elements, such as temporary identities and location area identifiers, in the context of UMTS conventional mechanism for user identity confidentiality.
explanation: The VLR is classified as a Network Function because it performs a specific task within the telecommunications network: managing user identity confidentiality data. This involves storing and retrieving information crucial for user authentication and location tracking.
