Proximus: and Nokia offer 5G network slicing innovation to support demanding network conditions
Proximus and Nokia announced today that they have successfully improved the performance of 5G network slicing under demanding network conditions through the use of radio software-defined networking and radio resource allocation technologies. . In a live trial at Proximus’ 5G Innovation Lab in Brussels, real applications were used to demonstrate how a consistent customer experience can be ensured under congested network conditions. The new 5G RAN slicing feature brings benefits to a wide range of use cases such as Industry 4.0, IoT and enterprise applications such as public safety and drone inspection, as well as virtual and augmented reality and cloud gaming.
The trial was performed on the Proximus 5G Innovation Platform using 50 MHz of spectrum in the 3600 MHz band based on Nokia’s AirScale 5G base station. It combined new advanced RAN slicing features in the base station with software-defined networking (SDN) radio technology to enable real-time management of network slices and performance. Three devices were configured across three end-to-end slices configured with 60, 30, and 10 percent of available bandwidth resources, respectively. Each device reached maximum bandwidth when connected individually and reached rated capacity when connected simultaneously.
The successful trial assigned specific radio resources per slice that were supplemented with other radio capabilities to reduce latency for slices with time-sensitive applications. It also highlighted how an operator can dynamically control and adapt slice parameters in general and define radio resources per slice in particular.
Nokia’s slice-aware radio resource allocation can be applied for 5G SA slices and 5G NSA traffic. It also complements capabilities already available in LTE, providing seamless continuity between 4G and 5G networks. Radio Software Defined Networking enables real-time management of RAN resources, schedulers, QoS, security, traffic isolation, and routing required especially to customize a slice based on specific business application and/or use case needs. It can be applied for 4G/5G slicing and edge slicing.
Nokia is the industry leader in 4G/5G network slicing and was the first to demonstrate 4G/5G network slicing on 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 broad ecosystem of devices and provide slice continuity across 4G and 5G.
Proximus offers a quality mobile network and national mobile coverage to its customers in Belgium. This trial supports the company’s ambition to be a leading innovator in mobile networks. In addition to its global expertise as a leading 5G player in Belgium, Proximus offers additional support, together with its affiliates, in complementary areas ranging from security and smart cloud solutions to artificial intelligence and the IoT.
We are delighted to have completed this network slicing trial with Nokia, which will provide our customers with enhanced network slicing capabilities that will keep key services running smoothly even during peak or busy times. Our advanced 5G network supports our customers’ businesses by enabling new types of services and making the network more efficient. We will continue to develop innovations and the latest applications, as our mission is to bring the opportunities of 5G to our customers.
This trial with our partner Proximus is the latest development in our pioneering history in network slicing. We’ve focused on delivering a consistent, slice-specific customer experience that works regardless of circumstances or network conditions. We have taken another key step with this project and delivered innovative new features that help our customers create new and engaging services.
