In mobile computing, VLR (Visitor Location Register) is a temporary database that stores information about subscribers who are currently roaming in its coverage area. It is crucial for managing mobile services and call routing while a subscriber is away from their home network. The VLR interacts with the HLR (Home Location Register) to obtain necessary subscriber details, such as user profiles and subscription data, to facilitate effective communication and service delivery.
VLR (Visitor Location Register) and HLR (Home Location Register) are both essential components in mobile network management but serve different functions. The HLR is a central database that holds permanent subscriber information, including user profiles, subscription details, and authentication data. The VLR, in contrast, is a localized database that stores temporary information about subscribers currently located in its area. It works in conjunction with the HLR to retrieve and manage subscriber data while they are roaming.
The full meaning of VLR is Visitor Location Register. It is a key element in mobile network infrastructure responsible for storing and managing temporary subscriber data when users are in a different location from their home network.
VLR is important because it enables efficient management of mobile services and communication for subscribers who are roaming outside their home network. It ensures that calls, messages, and other services are delivered accurately by temporarily storing subscriber information and interacting with the HLR to retrieve necessary data. Without the VLR, it would be challenging to provide seamless service continuity for users traveling between different network areas.
The VLR database is a temporary storage system within a mobile network that holds information about subscribers currently in its coverage area. This database contains data necessary for call routing, service delivery, and user authentication while the subscriber is away from their home network. It is designed to work in conjunction with the HLR to ensure that subscriber data is managed efficiently and services are delivered correctly.
