The Sonata Home Location Register (HLR) is a subscriber service database platform designed for CDMA2000® and 3G GSM/GPRS wireless networks. The Sonata HLR supports industry-standard protocols for wireless networks and can be optionally deployed with an integrated Authentication Center function to provide network security against fraud.
The Sonata HLR is available on a number of scalable hardware platforms. With small test or rapid-deployment systems, this HLR solution can also be deployed on the same hardware platform as the MSC and other core network elements. For larger commercial networks, the Sonata HLR is deployed on its own dedicated server, or in a High Availability configuration with duplicate servers and RAID array that provides a highly reliable system. The graphical user interface makes provisioning and subscriber maintenance simple and intuitive.
