Nokia completed the modernization of a Home Location Register (HLR) database for Vodafone India SuperNet. The company described the project as world's largest HLR upgrade, as its consolidated databases across 17 circles covering over 200 million entries. The number of database hosting nodes was also reduced from 46 to 12, improving efficiencies, enhancing performance and optimizing costs.
As part of the project, Nokia implemented its Subscriber Data Management (SDM) solution, which features Nokia's One-NDS (Network Directory Server), thereby consolidating network-related subscriber data into a single unified platform to be shared across multiple applications. Nokia's Systems Integration Services team seamlessly migrated the HLR database without disruption to Vodafone India's network and its 200 million subscribers, efficiently meeting a challenging deadline with the highest quality.
Nokia's SDM technology's geo-redundancy feature ensures that the subscriber database of one location is backed-up in the HLR of another in case of any incident like a network upgrade or natural disaster.
