What is NGN?

ITU definition

A packet-based network able to provide telecommunication services and

able to make use of multiple broadband, QoS-enabled transport

technologies and in which service-related functions are independent

from underlying transport-related technologies

Enables unfettered access for users to networks and to competing service

providers and/or services of their choice Supports generalized mobility which will allow consistent and

ubiquitous provision of services to users

What is NGN?

A multi-service Network able to support Voice, Data and Video.

A Network with a control plane (Signaling, Control) separated from the

Transport/ Switching plane.

A Network with open interfaces between transport, control and applications.

A Network using packet mode technology to transport of all kind of

information.

A network with guaranteed QoS for different traffic types and SLAs.

Migration towards the NGN appears to be inevitable

Journey to NGN

Digitisation had changed the complexion of telecom and IT

Different networks were made to carry information in digital format.

Individual service specific networks are developing into IP based

networks.

Possibility to offer different services of Broadcasting, voice, data,

video on same service specific platform.

Possibility of offering new innovative services to the subscribers

NGN is IP based platform to offer every thing on IP


5/25

Why NGN?

Fusion of services and markets

Common network for different services

IP in back bone dramatically reduced carriage cost

Split of different layers of network and thus ease of provisioning of

innovative services

Short time to define and provision of services.

Low Capex and Opex for provisioning of new services

Why NGN has become important?

This is march of technology either adopt or parish

Competition will provide innovative services and incumbent will have to

match

Present day technology will become obsolete will be costly to maintain

Drivers for NGN deployment :

Competition / Market forces

Different revenue streams

Convergence of services

Voice and impact of VoIP.

Services on mobile network mobile internet etc.

Benefits NGN Migration NGN is capable of providing seamless converged services from Telecom, Internet and

Broadcasting infrastructure at any time, anywhere to anywhere from any device to anydevice.

Co-existence with PSTN.

Access Technology Agnostic.

Distributed Architecture Call server at central location and MGWs at remotelocation.

Support Triple-play services. (Voice, Data and Video)

Open standard architecture.

Integrated users interface. Some of the applications which can be launched after migration to NGN networks.

VoIP

IP Centrex

Instant messaging/Presence/PTT/Push to view Multimedia services

xDSL

Traditional Analog & ISDN Subscriber services

IN Services (ex. Pre-paid & Toll-free etc.,.) IP Video

Video on Demand

Benefits NGN Migration

Improves cost effectiveness of data & voice transport Increased Call Capacity within a decreased footprint

Reduce inter MSC / Switch trunking costs through IP network

Opex Savings

Space and Power saving.

Control & Media functions separated (Distributed MGWs)

Backhaul enhancement using IP /MPLS

Software and provisioning costs

Software /features implementation in all Switches involves cost and time

consumes. In case of soft switch only Call server upgrades required.

Time to Market Feature development is faster and needs to be updated only on to

Application Server.

NGN in Access:

In old established networks prime deployment will be on copper, FTC and

FTH.

In developing telecom networks prime deployment would be on mobile

networks.

It is expected that new telecom networks will also concentrate on FTC andFTH/FTB.

Fixed mobile convergence for seamless rich experience to customers.

NGN regulatory and Licencing challenges:

Licencing--Should there be separate regime for core and access

Numbering ENUM or some other scheme

Interconnection Present mesh or interconnect exchange

Security Related IssuesNo geographical boundaries, LI, Network securityetc.

SpectrumA big question?

Universal services access.

Consumer protection.

NGN for better access

Broadband penetration : Large difference between developed and developingregion- Developing countries have penetration below 1%

Digital Subscriber Line(DSL)

Limited local loop

Local Loop unbundling not done by many countriesOptical Fiber Cable (OFC)

Penetration of Optical fiber in local areas is very low

Right of Way (RoW) is costly

Cable NetworkCable TV Networks is generally one way and are not able to

support broadband

Wireless

Limited availability of spectrumEnd user devices able to support BB are very costly

Unless last mile is upgraded, fruits of NGN will not reach to masses

NGN for better access- challenges in India

Wireless Broadband technologies will be useful for vast access coverage

Passive infrastructure such as mobile towers will play crucial role for faster

rollout of these services Sharing of passive infrastructure will be good enabler for broadband

growth

Infrastructure sharing needs to be mandated between operators

NGN will require lot of standardization & may face InteroperabilityChallenge

23

Challenges in NGN Access

The installation of new generation access networks requires heavier and

less flexible investments than those needed for transport networks.

The return on the investment is directly related to the customers response tothe introduction of new services as VoD, video calls, gaming online, etc.

The operators have a strong need for a clear and stable regulatory

framework for access networks.

Opportunities in NGN Access

Next generation core network

Next generation access network

Next Generation Access Network

Next Generation Access would provide much higher bandwidths to consumers

This would enable the supply of rich (but currently unspecified) multimedia

content

Disruptive change to existing services and existing business models

Investment risk driven by uncertainty as to consumers willingness to pay
