SEOUL, South Korea,
Feb. 15, 2017 /PRNewswire/ -- SK
Telecom (NYSE: SKM) announced today that SK Telecom (NYSE: SKM),
Deutsche Telekom (DT), Ericsson (NASDAQ: ERIC) have jointly built
and demonstrated the world's first intercontinental 5G trial
network. SK Telecom and DT network slices are now available in the
other operator's footprint - Korea and Germany are connected. A proof-of-concept has
been implemented and successfully evaluated, featuring the creation
and roaming extension of network slices optimized for Augmented
Reality (AR) and maintenance services.
The successful demonstration was hosted at DT's corporate
R&D center in Bonn, Germany
and SK Telecom's 5G Testbed at Yeongjong-do (BMW driving center),
Korea. It follows the joint announcement at MWC Shanghai 2016 by SK
Telecom, DT, and Ericsson of their global partnership to develop
the groundbreaking 5G technology for such a network.
"5G is not just a faster network. 5G will provide extreme user
experience anywhere and anytime, even when the user roams across
different operators globally", says Alex
Jinsung Choi, CTO SK Telecom. "Federated network slicing
will enable seamless platform sharing amongst operators at a global
scale for continuous and guaranteed user experience."
"Our customers are demanding global connectivity with a unified
service experience," says Bruno Jacobfeuerborn, CTO Deutsche
Telekom. "Network slicing is envisaged as a key enabler to support
multiple services in the 5G era. Today's breakthrough shows we can
extend that concept to ensure optimized service experiences with
global reach for our customers."
Ulf Ewaldsson, Senior Vice President, Chief Strategy and
Technology Officer at Ericsson says, "5G is the network for all
industries. Network slices in the context of 5G will be like
'virtual networks on-demand'. With this world's first
intercontinental 5G trial network, we truly demonstrate the
provisioning of network slices to global customers when
abroad."
In 5G, network slicing will allow the operator to configure an
end-to-end network that provides the desired overall functionality
and service parameters. Federated network slicing for 5G roaming
extends this concept to a visited network. This technology will
make it possible for an operator to provide a network service
globally, making sure that the customer does not need individual
agreements with different operators for a global service
experience.
New cooperation models
A pre-requisite for federated network slicing for 5G is an
enhanced cooperation model where operators open up their network to
host partner services. The home and visited operators must have
agreements in place that enable the recreation of a given network
slice in the visited network.
These agreements should cover aspects such as: network slice
availability at the access layer (cellular, fixed), availability in
the core network and the connection to customer application
servers. The hosting of edge cloud resources by the visited network
enables the execution of special business functions that demand
high throughput and low latency, close to the customer in the
visited network.
The proof-of-concept uses federated network slicing
functionality to run components of the 5G core of the home network
in the visited network. The demo featured an industrial maintenance
use case involving a repair worker communicating via AR with
support colleagues in a visited network. The scenario uses local
breakout and edge cloud to enable the best service experience in
terms of latency and throughput for the AR repairman.
MWC 2017
At SK Telecom's booth (3H10) in Hall 3 during MWC 2017, visitors
can witness how federated network slices can be created, managed,
and terminated in the form of NS-as-a-Service (Network Slice as a
Service). The created slices then can be used in various
applications, including V2X and connected cars.
At DT's booth (3M31) in Hall 3, the company has created its 5G
hub, where visitors can experience a variety of technologies -
including 5G-enabled robotics, the AR enriched slot car track and
robot telepresence application on federated network slicing - all
supported by extreme mobile broadband to guaranteed low
latency.
At Ericsson's booth (2N62) in Hall 2, visitors can enjoy the
company's joint demonstration with Deutsche Telecom and SK Telecom
on Federated Network slicing. Visitors can also engage in
conversations and demonstrations about Ericsson's innovations in
areas including 5G; platforms and services for IT and Cloud,
Networks and TV & Media; connected solutions for industries;
the Internet of Things; and partnering for success.
