• Project marks Nokia's largest ever migration of customer data to a cloud core platform
• Nokia-enabled migration of Grameenphone's entire customer base to cloud core platform marks significant milestone in the company's transformation into a Digital Service Provider 
• First deployment of hybrid cloud core network in Bangladesh 

20 February 2019, Dhaka, Bangladesh - Nokia and Grameenphone have completed the migration of Grameenphone's 72 million customers to the Nokia User Data Convergence (UDC) cloud core platform. The project, Nokia's largest ever migration of customer data to a cloud core platform, marks a key milestone in Grameenphone's journey to become a Digital Service Provider (DSP).

Nokia deployed the solution in two cities in Bangladesh as part of an agreement with Grameenphone's parent company, Telenor. Under this agreement, Nokia will move all of Telenor's Asia subsidiaries to a cloud core platform, located in their respective countries of operation, driving new cost and operational efficiencies. It will also simplify the way new technologies and services are introduced, allowing Grameenphone to attract new subscribers.

Nokia developed a delta migration tool to complete the transfer from legacy Home Location Register (HLR) to the Nokia cloud UDC platform. Nokia also developed a 'mini provisioning system' to ensure successful completion of the project.

Rade Kovacevic, Chief Technology Officer of Grameenphone, said: "We are delighted by the successful migration of user data to the Nokia cloud UDC platform. Nokia completed the project within a challenging timeline - even migrating 31 million subscribers over one night - and we will continue to leverage the company's expertise and cloud technology in our journey to becoming a digital service provider to drive further operational efficiencies."

Rashed Haque, head of the Bangladesh Customer Business Team at Nokia, said: "Leveraging our extensive technology expertise and working closely with Grameenphone,  we aligned with the company's vision to resolve its key issues. By moving Grameenphone toward cloud technology, the operator will be able to reduce operational costs while enhancing service quality for its customers. We are confident that Grameenphone will transform itself into a digital service provider and better address the evolving needs of its subscribers."
