Nokia and Shanghai Mobile deploy innovative VoLTE performance optimization platform for high quality voice calls in Shanghai

• Nokia and China Mobile subsidiary demonstrate innovative techniques to optimize VoLTE performance at Mobile World Congress Shanghai 2016

• 700,000 subscribers in Shanghai already benefit from Nokia technology providing end-to-end network monitoring to ensure consistent high-quality 4G voice service

• Predictive Optimization approach combines big data collection, storage and processing and sharing capabilities to automatically detect performance issues and allow operators to quickly deploy high quality VoLTE services.

Mobile World Congress Shanghai 2016, China - Nokia and China Mobile are showcasing at MWC Shanghai end-to-end VoLTE optimization technology, which has already ensured the smooth rollout of high-quality voice services over 4G for the operator in Shanghai.

Working with Shanghai Mobile, China Mobile's regional subsidiary, Nokia has applied its technical and professional services expertise to combine big data collection, storage and processing capabilities to develop an analytics platform monitoring signalling data across the network at all times. Deployment of this technology allowed Shanghai Mobile to quickly expand its VoLTE service from hundreds of pre-commercial users to the more than 700,000 subscribers to its 4G network in Shanghai.

Optimization of the Shanghai Mobile's VoLTE in Shanghai is underpinned by the platform, which enables end-to-end performance management and assurance across a multi-vendor core and radio network. Intelligence analytics are used to identify issues in real time, such as the setting up of a new mobile device as it joins the network, allowing Shanghai Mobile to resolve the issue and minimize impact to quality of service.

At Mobile World Congress Shanghai 2016, Nokia and China Mobile is using real data from Shanghai Mobile's network to demonstrate VoLTE performance management, KPI monitoring, network troubleshooting and service optimization. This builds on earlier conceptual demonstrations of Predictive Optimization powered by Nokia AVA at Mobile World Congress Barcelona in March 2016.

Bu Tong, GM of Mobile Network at Shanghai Mobile, said :

"Using Nokia's innovative technology we could quickly roll-out VoLTE to our subscribers in the most efficient way, knowing that we could easily identify and solve any network anomaly as we did so."

Dennis Lorenzin, head of Mobile Networks Network Planning & Optimization at Nokia, said :

"This is another important achievement in a long-standing collaboration with China Mobile and its subsidiaries. Working with Shanghai Mobile we have developed a highly competitive end-to-end approach to optimizing VoLTE performance. In future, the Nokia AVA platform will enable us to replicate this with other operators across the globe to ensure the fast roll-out of commercial VoLTE services, ensuring the provision of the highest-quality voice telephony possible."
