Nokia and Google have successfully tested an innovative network slice selection functionality on 4G/5G networks using UE Route Selection Policy (URSP) technology and Google Pixel 6 (Pro) phones running Android 13. It promises to enable operators to provide new 5G network slicing services and enhance the customer application experience of devices with Android 13. Specifically, URSP capabilities enable a smartphone to connect to multiple network slices simultaneously via different enterprise and consumer applications depending on a subscriber’s specific requirements.
The trial, which took place at Nokia’s network slicing development center in Tampere, Finland, also included LTE-5G New Radio slice interworking functionality. This will enable operators to maximally utilize existing network assets such as spectrum and coverage.
URSP capabilities extend network slicing to new types of applications and use cases, allowing network slices to be tailored based on network performance, traffic routing, latency, and security. For example, an enterprise customer could send business-sensitive information using a secure and high-performing network slice while participating in a video call using another slice at the same time. Additionally, consumers could receive personalized network slicing services for example for cloud gaming or high-quality video streaming. The URSP-based network slicing solution is also compatible with Nokia’s new 5G radio resource allocation mechanisms as well as slice continuity capabilities over 4G and 5G networks.
The trial was conducted using Nokia’s end-to-end 4G/5G network slicing product portfolio across RAN-transport-core as well as related control and management systems. The trial included 5G network slice selection and connectivity based on enterprise and consumer application categories as well as 5G NR-LTE slice interworking functionalities.
Nokia is the industry leader in 4G/5G network slicing and was the first to demonstrate 4G/5G network slicing across RAN-Transport-Core with management and assurance. Nokia’s network slicing solution supports all LTE, 5G NSA, and 5G SA devices, enabling mobile operators to utilize a huge device ecosystem and provide slice continuity over 4G and 5G.
Nokia has carried out several live network deployments and trials with Nokia’s global customer base including deployments of new slicing capabilities such as Edge Slicing in Virtual Private Networks, LTE-NSA-SA end-to-end network slicing, Fixed Wireless Access slicing, Sliced Private Wireless as well as Slice Management Automation and Orchestration.
