ITU to study the network standardization requirements
of ‘5G’
Open group to identify the standardization needs of future networks
Geneva, 5 May 2015 – ITU has established a new Focus Group
to identify the network standardization requirements for the ‘5G’ development of
International Mobile Telecommunications (IMT) for 2020 and beyond.
The network studies will be hosted by ITU’s Standardization Sector (ITU-T),
benefiting from the strength of ITU-T standardization in wireline
communications.
These "IMT-2020" systems will enable wireless communication to match the
speed and reliability achieved by fibre-optic infrastructure. The potential
application fields of IMT-2020 systems, in addition to voice and video, span
from healthcare to industrial automation, virtual reality, automated driving,
and robotic systems controlled with an imperceptible time lag. One-millisecond
end-to-end latency is necessary for technical systems to replicate natural human
interaction with our environment, a goal that experts say should be within reach
of future networks.
In 2012, ITU established a programme on International Mobile
Telecommunications (IMT) for 2020 and beyond, which provides the framework for
IMT-2020 research and development worldwide. ITU’s Radiocommunication Sector
(ITU-R) is coordinating the international standardization of IMT-2020 systems.
ITU-T is expected to play a similar convening role for the technologies and
architectures of wireline networks.
ITU Secretary-General Houlin Zhao: “Air interfaces and radio access networks
are progressing rapidly, but there is a need to devote more attention to the
networking aspects of IMT-2020. Wireline communications will transform
significantly in support of IMT-2020, and the coordination of ITU’s
standardization and radiocommunication arms will ensure that the wireline and
wireless elements of future networks develop in unison.”
Director of the ITU Radiocommunications Bureau, François Rancy: “Following on
from the successful development of IMT-2000 and IMT-Advanced, the standards for
all of today's 3G and 4G mobile systems, the work to be carried out by ITU-T on
the network aspects will be an important complement to the activities undertaken
by ITU-R in developing the radio interface standards for IMT-2020.”
Director of the ITU Telecommunication Standardization Bureau, Chaesub Lee:
“Today’s network architectures cannot support the envisaged capabilities of
IMT-2020 systems. Innovation in standardization is essential across core
networks, access networks, virtualized data clusters and masses of smart
networked units. Moving beyond convergence, the concepts underlying networking
must evolve to support the development of integrated fixed-mobile hybrid
networks.”
Head of 5G Research and Development at Huawei, Wen Tong: “5G will power a
wide range of new user experiences, but the bottleneck remains the speed of the
network. Everyone in the ICT ecosystem needs to work together. This is the most
important condition for us to realize 5G, and this is the reason Huawei is
contributing to ITU’s efforts to consider what the road to 5G demands of all
parts of the ecosystem.”
The new Focus Group, which is open to participation by any interested party,
will provide the launching point for ITU-T’s contribution to IMT-2020
standardization. The group will follow an intensive work plan to complete its
study prior to the December meeting of ITU’s standardization expert group
responsible for future networks, cloud computing and network aspects of mobile
communications,
ITU-T Study Group 13.
IMT-2020 research and development is underway in a wide range of industry and
public sector bodies. The Focus Group’s scope of activity will be concentrated
in identifying the standardization needs of the wireline elements of 5G
networks, building on an analysis of IMT-2020 studies being undertaken by other
entities.
ITU-T standardization activity based on the findings of the Focus Group will
prioritize the alignment of its IMT-2020 deliverables with those of ITU-R,
ensuring that standardization work on the network aspects of IMT-2020 supports
the further evolution of IMT.
Note to the editor:
ITU-T Focus Groups are formed in response to immediate ICT
standardization demands, charged with laying the foundations of subsequent
standardization work in membership-driven
ITU-T Study Groups. Focus Groups are open to organizations
outside ITU’s membership and they are afforded greater flexibility in their
chosen deliverables and working methods.
