Information on Visitor Location Register (VLR)

The CDMA visitor location register (VLR) is a database that contains temporary information about subscribers which is needed by the MSC in order to service visiting subscribers. When a mobile station roams into a new MSC area, the visitor location register connected to that mobile switching center will request data about the mobile station from the home location register, reducing the need for interrogation of the home location register.
     The CDMA visitor location register is part of the executive cellular processor.
