In the first project of its kind, TeliaSonera is unifying subscriber data from six countries onto a single platform to achieve higher operational efficiency and faster time to market.
Part of an extended network modernization program, TeliaSonera has implemented an initiative to bring together subscriber data from six countries onto a single management system. When finally completed in about two years, the project will enable TeliaSonera to service ten million mobile subscribers in Denmark, Estonia, Finland, Lithuania, Norway and Sweden from a single access point.
To help it achieve its ambitious goal, TeliaSonera has chosen the Nokia Siemens Networks Subscriber Data Management solution, encompassing One-NDS centralized subscriber repository, Home Location Register (HLR), Home Subscriber Server (HSS) and Mobile Number Portability (MNP).
“The platform will consolidate into a single database all the subscriber data from multiple applications across our GSM, 3G and LTE networks in six countries. Centralizing the data will simplify our systems and enable us to reduce our operational workload. While the cost savings won’t quite be down to a sixth, they will still be significant,” explains Mr. Tommy Ljunggren, Vice President for Systems Development, TeliaSonera. “We will also achieve a much faster time to market for services, saving up to months in the most complex cases.”
Consolidation of data also reduces greatly the number of network elements and sites needed, resulting in lower operational costs and maintenance effort.
Managing more customers, more easily
Nokia Siemens Networks One-NDS provides open interfaces for the seamless integration of any network application, as well as Operations and Business Support (OBS) and Customer Relationship Management (CRM) systems. This capability will allow TeliaSonera to generate insights on customer behavior easily and develop services catering to the specific needs of different users.
Integrating the platform with its existing IP Multimedia Subsystem (IMS), also from Nokia Siemens Networks, will further enable TeliaSonera to widen the management of subscribers to include its fixed line customers. “Clearly, the Nokia Siemens Networks SDM solution will be easier to integrate with our IMS, but the key reason we selected the system was its proven reliability in several deployments around the world,” says Ljunggren.
The Nokia Siemens Networks One-NDS subscriber database solution has been deployed by 110 operators serving more than 1.8 billion subscribers worldwide.
“When you are putting so much critical data onto one system you cannot afford for it to fail. The robustness of the solution is absolutely crucial and it’s a challenge when six countries are involved,” Ljunggren concludes.
