Nokia to provide China Unicom core networking products for 5G

Finnish telecom company Nokia has bagged China Unicom's deal to support the buildout of its 5G SA Core network in China, marking an expansion of its existing 4G working relationship with the Chinese communication service provider.

Nokia has been awarded an approximately 10% share of China Unicom’s 5G core network. The core network performs a variety of functions, including setting up connections, bandwidth management, scaling and securing the network, and, now with 5G, opening up the network to support new, software-enabled use cases such as network slicing.

The Nokia Cloud core products that China Unicom selected provide Unified Data Management, Session Management, and User Plane functions, and are complemented by Data Refinery and NetAct, all deployed on Nokia’s CloudBand.

Unified Data Management, a critical function with the arrival of 5G and the evolution to cloud architecture, manages all subscriber data and services efficiently and cost-effectively. The Session Management Function is a fundamental element of the 5G Service Based Architecture, primarily responsible for interacting with the decoupled User Plane Function as well as subscriber session management. The User Plane Function delivers the packet processing foundation for the Service Based Architecture, by allowing packet processing and traffic aggregation to be performed closer to the network edge, thereby increasing bandwidth efficiencies while reducing costs.

The deal also includes products from Nokia’s Cloud Packet Core portfolio, including the Nokia Cloud Mobile Gateway. The product provides the 5G standalone Session Management Function and User Plane Function, in addition to supporting the 4G Serving Gateway and the Packet Data Network Gateway in China Unicom’s network.

Nokia currently has a 17% market share in China Unicom’s rapidly expanding VoLTE network, where it has deployed Nokia’s cloud-based vIMS platform. This deal will further enhance the long term partnership between China Unicom and Nokia. Nokia has provided critical support in getting China Unicom’s 4G network successfully established, and will continuously support China Unicom in its 5G networks up and running in the future leveraging its advanced core network solutions.
