Huawei 5G Transport Helps Telefonica Demonstrate the Industry’s First 5G Slicing-based Interactive VR Service

[Barcelona, Spain, February 27, 2018] During the Mobile World Congress (MWC) in Barcelona, Telefonica and Huawei jointly demonstrated the industry’s first VR service using 5G end-to-end (E2E) network slicing technology underpinned by Telefonica’s UNICA program. This demonstration involved the wireless access network, core network, transport network, and terminals, with the transport network being formed by one of the industry’s first network slicing routers for 5G transport from Huawei.

Network slicing enables operators to divide a set of hardware infrastructure into multiple virtual E2E networks to adapt to various types of services with different characteristics. This demonstration provided evidence of how 5G network slicing can enable on-demand diversified services and ensure high bandwidth and low latency, helping operators to achieve business success with 5G. It also represented the latest achievements in 5G key technology verification and use case research, marking another significant milestone of the continued joint innovation and strategic cooperation between Huawei and Telefonica.

Huawei’s 5G E2E network slicing technology utilizes service-oriented network architecture, network function modularization, and CU separation. On the mobile bearer network, Huawei’s network slicing routers can generate network slices based on the SLA requirements of 5G services. Network slices are isolated using FlexE technology to ensure that services on different slices do not interfere with each other, meeting the diversified transport requirements of 5G services. The network resources within each network slice can be fully utilized through statistical multiplexing to maximize the network value.

Huawei has also launched its 5G-oriented X-Haul mobile bearer network solution. Before this demonstration, Huawei and Telefonica verified multiple key X-Haul technologies in a lab environment. These technologies include PAM4-based 50 Gbit/s ports used to effectively reduce 5G network construction costs, FlexE bundling used to smoothly evolve bandwidth, and SR+EVPN used to simplify network protocols, unify service bearing, and make network connections simpler, more flexible, and more efficient.

Javier Gavilan, Planning and Technology Director Core Network, Platforms and Transport, Telefonica Global CTIO Unit, said: “We are very happy to demonstrate this VR service with Huawei in the MWC. Telefonica is committed to becoming a pioneer in the 5G era and will work with Huawei through joint innovation to promote 5G commercial use.”

Gao Ji, President of Huawei Router & Carrier Ethernet Product Line, said: “5G brings many challenges to the transport network in terms of bandwidth, latency, slicing, and architecture. The tests of key 5G transport technologies and this demonstration conducted by Telefonica and Huawei show that the transport network can overcome the challenges facing it and lead the future development of 5G. Huawei is excited to work with Telefonica and embrace the 5G era together.”

MWC 2018 runs from February 26 to March 1 in Barcelona, Spain. Huawei is showcasing its products and solutions at booth 1J50 in Fira Gran Via Hall 1, booth 3130 in Hall 3, and the Innovation City zone in Hall 4. For more information, please visit:
