China Unicom plans to deploy a cloud-native core network based on Nokia AirGile technology in seven Chinese provinces.
The deployment of the Nokia cloud-native core network will enable China Unicom to deliver Voice-over-LTE (VoLTE) and Voice-over-Wi-Fi (VoWiFi) capabilities from a single platform, as well as new services such as 'one-number, multi-devices'.
As a result subscribers will experience high definition voice calling, faster call set-up and seamless connectivity as they move between China Unicom's 4G network and Wi-Fi access points, and receive calls on multiple connected devices.
Nokia will deploy its technology in seven provinces in China, including major industrial and tourist hubs: Sichuan, Inner Mongolia, Jilin, Hainan, Yunnan, Gansu and Hunan. The network will include Nokia AirGile cloud-native core technologies as well as the Nokia AirFrame data center, NetAct, CloudBand and Session Border Controller. Nokia will also act as a product and systems integrator.
In 2017 Nokia and China Unicom began interoperability with other vendors' equipment, enabling China Unicom to be the first operator to deploy a three-layer decoupled network architecture using network functions virtualization to decouple hardware and software and ensure flexibility allowing each network layer to evolve independently.
