The road to 5G

3

5G will cover new use cases and requirements

BB access in dense areas

• Seamless experience of connectivity anytime,

anywhere, on any access technology

• Video services, possibly empowered by 3D and

Augmented Reality

BroadBand access everywhere

High user mobility

• High user mobility on trains, while still enjoying HD movie

or work in a videoconference

+50Mbps

everywhere

Speed up to

500Km/h

Up to 1 Gbps

4

Use cases and requirements

Extreme realtime communications

• Ultra low power, integrated sensors, e. g. wearable

to measure various heart rate or blood pressure, …

• Real-time sensing, data delivery, big data intelligence

and real-time actuation to enable Tactile Internet

Massive IoT

Emergency & Safety

• Public Protection and Disaster Relief e.g. especially for

communication among authorities and citizens

Use cases and requirements

Broadcast like services

• Monitoring patients & fast medical treatment.

• Vehicles realize critical situations fast, react

accordingly and alert other cars…

• Information distributions in areas such as arenas,

event locations, city centers, city metros

What is 5G?

An extremely flexible and highly programmable e2e system, application, customer,

time and location aware

Serving at best high diversity types of communications (Human & Machine) with

different performance attributes

Natively leveraging NFV technologies:

► Support on demand composition of network functions and capabilities

► Enforce required capability/capacity “where and when needed”

Profitably accommodating low- and high-ARPU traffic and sustainability thanks to cost

saving and new business opportunities

Being future-proof and ready to serve even not yet identified use case and radio

technologies

Key issues to reach 5G

5G Common composable network Use case driven creation of dedicated networks optimized for specific service scenarios / customers

(network slices)

Combination of functions available in a catalogue, through the NFV Orchestration Platform

Only virtualisation can allow the

needed flexiblity and sustainability

Mobile lifecycles: from early studies to standardIs it too early to work on 5G?

• Major technology shift

roughly once every 10

years.

• Standardization

usually starts 4-5

years before the first

commercial launch of

a new generation

• R&D activity usually

starts 2-3 years before

proposals come to

standards…

Handover from 5G to

2G/3G?

CS Fallback for 5G

NFV,SDN, MEC….++

Software will have a key role in the

5G Convergent Network

What else? Softwarisation

Source IEEE/NTT-DOCOMO

14

Mobile Fronthaul: another aspect

of Softwarisation

C-PRI, ETSI ORI, projects as i-JOIN

are defining the radio side and the

functional splitting

Figures are somehow worrisome

What else? Fronthaul and backhaul evolution

ITU-T natural home for the fibre network

aspects

Collaboration is needed with the radio and

mobile architecture groups to assure

compatibility and best efficiency of the

solutions

15

Future networking: will IP still satisfy the 5G performance requirements?

What else? New Networking

Requirements on delay and reliability could in some cases be not easy to meet in

classic IP networksReplace?

Relay ?

Integrate?

New concepts as ICN, CCN….
