DT, Ericsson and Samsung cut a portion of 5G for virtual reality games in lab tests

Deutsche Telekom completed the cutting-edge 5G network cut-off with Ericsson and Samsung in a lab test that erased specific resources to deliver the performance needed to support virtual reality games in the cloud.

The partners have described it as world first.

The test used a Samsung Galaxy S21 device and a connected VR headset. Ericsson provided a standalone 5G infrastructure, including radio access network (RAN), cloud core, orchestration, and command automation.

Network segmentation is one of the ways in which operators expect to earn revenue with 5G, with the ability to isolate and adapt parts (or “slices”) of the larger network from end to end to adapt to specific needs of different customers or use cases.

DT and Ericsson focused on RV games as an example, using two full network slices, with the other representing a typical mobile broadband part. The VR part was optimized for higher performance and low latency that would be desirable for cloud gaming. According to Ericsson, it showed a better experience even when the network was congested.

The demonstration examined multiple capabilities for end-to-end 5G network splitting, including verifying that latency remained stable and could ensure some performance on a congested network. He also explored the possibility of automating the creation of separate cuts for different services and isolating network resources with Ericsson’s 5G RAN segmentation product; and the integration of the business support system (BSS) for the provision of user profiles and automated cuts with orchestration

A commercial Ericsson 5G RAN segmentation product launched earlier this year, which said it allocates radio resources based on dynamic network partitioning and offers 1 millisecond scheduling.

DT and Ericsson executives noted the need to show what network cutting can do for consumers, as operators aim to introduce new services based on cutting.

“The network cut is a key factor in the monetization of 5G. New digital services for consumers and businesses are becoming a reality, as technology makes it possible to create appropriate programs for defined virtual networks with defined features, “Erik Ekudden, technical director of the Ericsson Group, said in a statement. “To bring these services to market, it is vital that operators start from their own business and collaborate with customers as well as relevant ecosystem agents to demonstrate value creation and technical readiness.”

As an experience-focused company, “it is essential to demonstrate the value of the 5G division for the lives of our customers,” said Claudia Nemat, a member of DT’s technology and innovation board. “As a first world, our unique partnership with Ericsson and Samsung to provide cuts to commercial devices illuminates how we can bring these benefits to our customers.”

Another key success that Ericsson called for was the use of an EU 5G (user equipment) cut-off policy feature. The provider said it allows a device to target applications and services with specified requirements to a defined segment. A device that uses certain applications, such as cloud gaming, which requires low latency, could direct the application to the right part of the network that could handle these requirements for better service quality.

As for Deutsche Telekom, parent company of T-Mobile, the operator has been making open RAN noise this week and has activated its deployment of O-RAN Town in Neubrandenburg, Germany. The top 25 open RAN network sites from various vendors are now deployed and integrated into DT’s live network in Germany.
