Nokia executes HLR modernization for Vodafone SuperNet in India

Nokia has completed the world’s largest modernization of a Home Location Register (HLR) database for Vodafone India SuperNet.

The modernization entailed consolidating subscriber 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 – delivering a seamless network experience and ensuring business continuity for the Vodafone SuperNetTM.

Vishant Vora, Director – Technology, Vodafone India, said: “This is a big step towards delivering the Vodafone SuperNetTM experience to our customers. We believe we have executed the world’s fastest and largest subscriber database migration without any network or services disruption. Further, our customers will benefit from faster, more efficient provisioning. The increase in network resiliency will help us recover quickly in case of natural disasters. Nokia has been our trusted partner over the years and has once again done a commendable job in executing this complex and significant program ahead of schedule.”

Sanjay Malik, Head of India Market, Nokia, said: “We are excited to help Vodafone deliver the SuperNetTM experience. As operators are focusing on making their networks more agile and subscriber-centric, we are providing our customers with solutions to deliver a superior experience. This program is the result of a strong and enduring relationship with Vodafone India in which we share their vision for enhancing the customer experience and improving efficiency.”
