  • Groundbreaking system features low latency edge cloud, E2E network orchestration for managed latency, an intelligent converged core network and network aided position tracking
  • End-to-end 5G system supports both consumer and vertical industry applications on same platform
  • DT raises the bar for 5G innovation together with Huawei, Samsung and Stanford University

Mobile World Congress 2017: Deutsche Telekom (DT), Huawei, Samsung and Stanford University demonstrate an all-cloud based 5G end-to-end network system. It includes advanced slicing mechanisms, that delivers 5G capabilities as on-demand services for both consumer and industry use cases over one physical platform. The groundbreaking system includes state-of-the-art features in radio, fixed and transport networks, the demonstration of an intelligent converged core network as well as physical isolation ultra-low latency edge computing technology along with network aided position tracking.

“We engage strongly with our customers in the development of 5G. The verticals are telling us they require 5G guaranteed low latency for Industrial Internet use cases. Consumer digital services are evolving towards real time AR/VR and more,” says Bruno Jacobfeuerborn, CTO at Deutsche Telekom Group. “All cloud network slicing will be a key enabler, and we show how both consumer and industrial use cases can be served on-demand over one platform. This is an important breakthrough on the way to making the 5G differentiators tangible.”

5G is simply different

DT has proven that 5G will be more than just about sheer speed. The diversified requirements from new applications will be enabled in a cost efficient manner by 5G end-to-end network slicing. Deutsche Telekom’s 5G:haus innovation laboratory is making these 5G differentiators tangible with its end-to-end network system.

Visitors to Deutsche Telekom’s booth at the MWC in Barcelona experience why 5G capabilities will be key to the adoption of applications such as  Augmented Reality (AR) and cloud robotics.  The enriched AR showcase is enabled on an extreme Mobile Broadband (xMBB) slice that provides the capabilities needed for more mobile AR experience. Whereas, typically all the compute, position tracking and sensing is local, 5G networks can offload many of these tasks, enabling light-weight headsets and significantly enriching the user experience. The showcase leverages the 5G system’s high throughput, low latency compute offload and network-aided position tracking technology – all provided over the same wireless infrastructure with an edge cloud. The unique centimeter precision position tracking technology is provided by Stanford University.

The cloud robotics showcase benefits from the low, reliable and thoroughly managed latency in the end-to-end orchestrated system. It is based on a guaranteed latency (GLA) slice that ensures real time collaboration between robots in a production environment. A further showcase demonstrates how 5G can enable truly seamless customer experience based on convergence between fixed and mobile access networks: Fixed Mobile Convergence (FMC). Visitors experience a seamless digital live entertainment across spaces, devices and access technologies. This true Fixed Mobile Convergence (FMC) approach is enabled by the system’s converged and integrated core network that is access agnostic.

All-Cloud Network Slicing

The 5G end-to-end network slicing technology is based on Huawei’s all cloud architecture. The high gigabit throughput is realized with Massive MIMO in the C-band. The radio resources are allocated for the eMBB slice and GLA slices by the CloudRAN based on slice awareness capability. So the whole network can be sliced end-to-end across access, transport and core.

The transport network achieves data plane isolation over the IP and optical Infrastructure by maintaining different network topologies and SLAs (service level agreement) with the respective control planes. The low latency scheduling process and edge computing technology of the 5G oriented core network realized ultra-low latency and ultra-low latency with high mobility. The network slicing management function provides the slice design, deployment and monitoring capabilities for fast operation. The converged and integrated core network is access agnostic.

5G Radio solution with Guaranteed Latency 

In the 5G end-to-end network chain, every single element contributes to the end-to-end latency. For the Guaranteed Latency (GLA) network slice each network segment needs to control its latency contribution. The Radio Access is no exception to this statement. Samsung’s GLA feature embedded in its 5G radio system ensures guaranteed latency and Quality of Service (QoS). At the same time the feature enables the efficient use of the scarce radio resources. Guaranteed low latency is required in areas that demand real-time communication such as industrial services and autonomous cars. The showcase demonstrates the use and function of GLA using robotic arms.

5G Network Aided Position Tracking

5G enabled applications such as AR/VR, drones and automated driving require centimeter level position tracking. Currently such tracking is provided by sophisticated hardware that needs to be integrated within the AR/VR glasses or drones for instance. Stanford University’s network based position tracking technology provides centimeter precision position tracking purely from network based measurements. This will allow AR/VR and drone designers to offload this capability to the network, enabling lightweight headsets and drones and delivering a great user experience.
