Flexible networks for Beyond 4G

Lauri Oksanen Head of Research Nokia Siemens Networks



Key requirements towards 2020

Support up to 1000 times more traffic

Enable Gbps peak speeds

Reduce latency to milliseconds

Deliver safe superior customer experience

Make networks self-aware, self-adaptable, and intelligent

Improve energy efficiency

We cannot predict all the use cases so flexibility is a key requirement

Manage up to 10 times more users



Key requirements towards 2020, Performance

+ further innov.

Most of these will be small cells

In addition over 500M WiFi APs



3GPP Release 12 will bring significant performance boost…

Rel12 Feature Benefit

Small Cell Enhancement

based on Inter-site CA

• Optimized small cell mobility by reducing RAN to CN signaling

• Improved data rates by using macro and small cells together

• Efficient use of TDD spectrum

New Carrier Type (NCT) • Minimized inter-cell interference

• Lowered BTS energy consumption

• Significant overhead reduction

Elevation beamforming / 3D-MIMO • Significantly enhanced macro cell capacity and coverage

Advanced receivers • Removing interference to increase UL and DL capacity

Enhanced SON • Efficient operation of dense small cell deployments

• Energy savings in small cell capacity layers



But we can further optimize a Beyond 4G Local Area Radio

System Requirements for B4G Local Area

• Always connected, 10Gbit/s peak data rate, 1ms RTT

• Support flexible deployment and new use cases

• Low cost, low power consumption

TDD is an attractive duplexing method

• Flexible UL/DL duplexing

• Fluent support of access, self-backhauling and D2D

• Low cost RF

• Reciprocity gains for MIMO

Component technology evolution is main enabler to allow low TDD latency

• E.g. fast switching



Further in the future, millimeter wave band is promising

Huge spectrum available at 71-95 GHz

Advantages

• Can easily meet B4G peak and edge data rates

• Exploit beamforming gains using massive antenna arrays

• Access and backhaul can use same radio

Development needed in several areas like

• mm-wave integrated circuits

• Antenna array architectures

• mm-wave propagation



Key requirements towards 2020, Management











Advanced Self Organized Networks will make it possible to manage all the radios, layers, and frequency bands

All cells and frequency layers automatically managed by advanced SON

All spectrum under unified resource management for instant capacity and coverage optimization

Cognitive networks will reduce errors, improve quality and lower operation and energy costs

Virtually one ubiquitous connectivity

SON is maturing in environments where information is readily available

But current automation does not deal well with unclear data and unexpected cases

Network automation in uncertain information environment calls for artificial intelligence technologies



Key requirements towards 2020, System architecture











Our vision of a liquid network architecture for experience, efficiency, and flexibility

Heterogeneous broadband access & smart agile transport

Local data centers hosting multiple intelligent network applications

Central DC for efficient network control/operation and XaaS offerings

Flexibility & scalability through virtualization and automation



Combining network and cloud for end-to-end virtualized service delivery

Network Cloud Compute & Storage Cloud

Virtual Resource Manager-NW Virtual Resource Manager-IT

Virtualized Network Infrastructure Virtualized IT Infrastructure

Virtualized Service Infrastructure

Virtual Network Controller combined with Virtual Compute Controller



Key requirements towards 2020, Security











Telecommunication becomes even more critical infrastructure to enable the smart cities and societies of the future

Traffic & Logistics Emergency

Health Care Government

Electricity Finance Food/water supply

Education

Communication networks

One network used for every kind of application



A connected world with billions of smart phones and devices needs to be protected also by the network

Mobiles are becoming the most attractive target for attackers

Infected mobiles can be effectively used to attack the network

Network-based anomaly detection

Network-based mobile malware protection, intrusion prevention

Secure connectivity and content



Our 20/20 vision…

Mobile networks able to deliver one Gigabyte of personalized data per user per day for less than a dollar a day
