The Provisioning Database Interface (PDBI) allows one or several independent information systems, supplied and maintained by the network operator, to be used for provisioning databases and for configuring systems. Through the PDBI, client systems may add, delete, change or retrieve information about any IMSI, DN, or Network Entity association. For this application a Network Entity generally refers to an HLR (Home Location Register).
This feature allows mobile network operators to optimize the use of subscriber numbers (IMSIs and DNs) and number ranges by providing a logical link between any DN and any IMSI. This permits subscribers to be easily moved from one HLR to another. It also allows each HLR to be filled to 100 percent capacity by allowing DN/IMSI ranges to be split over different HLRs and individual DNs and IMSIs to be assigned to any HLR. This also eliminates the need to maintain subscriber routing information at every MSC in the network.
The provisioning client application is responsible for establishing the TCP/IP socket connection, creating and sending PDBI requests, receiving and processing PDBI responses, and detecting and handling socket errors.
The menu options allow you to configure PDBI Options, allow and configure PDBI connections, set PDBI blacklist ranges, and to schedule PDBI exports.
