The call apparently took place within 25 days of Nokia’s software being deployed.
The firm claims this proves the interoperability of Nokia Software’s products, regardless of the hardware environment.
Nokia also said it expects to achieve full deployment of a number of software solutions with China Unicom several weeks ahead of schedule.
No standalone
The data and voice calls, which marked firsts for Nokia on a 5G SA network, were completed earlier than planned and by bypassing non-standalone (NSA) 5G core deployments, Nokia was able to deliver 5G SA core for China Unicom and enable network functions, such as network slicing capabilities.
The company deployed its Unified Data Management, Shared Data Layer (5G Unified Data Repository), and Cloud Mobile Gateway (from its Cloud Packet Core portfolio) for the 5G Session Management Function and User Plane Function.
This was complemented by Data Refinery charging and NetAct network management, with all products deployed in the cloud using the Nokia CloudBand cloud infrastructure and management solution.
Bhaskar Gorti, President of Nokia Software and Nokia Chief Digital Officer, said, “This key milestone with China Unicom…illustrates that the transition to 5G standalone networks can be completed rapidly – regardless of existing hardware, and that is part of what makes Nokia Software products distinct.”
