Current multimedia service delivery landscape

Service delivery challenges on legacy networks

Why NGN?

Access, Transport, Network and Application layer development for delivery of NGN services

NGN implementation challenges

Looking into the future…….


3

Current Service Delivery Landscape

Developments in access network technology

e.g. mobile – HSPA, HSPA+, WiMAX, LTE high bandwidth transport

Expanding competitive landscape

Increased competitionInternet based services

Telco Operators Bit pipe providers


4

Service delivery challenges on legacy networks

Service deployment time (Time To Market) – competitive edge

High Capex and Opex on new services – vertical silos

Deployment of advanced & Value Added Services

Strategic differentiation from internet based services

Quality of Service (Operator VOIP vs. Skype)

Security

Vertical Silos in service deployment

Why NGN?ITU definition - A Next Generation Network is a,

packet-based network able to provide telecommunication services

able to make use of multiple broadband access technologies

QoS-enabled transport technologies, and

in which service-related functions are independent from underlying transport related technologies

New revenue through NGN services

Flexible service deployment across multiple platforms

Reduction of Capex and Opex

Modular, scalable and flexible platforms


5

NGN – layered ArchitectureGeneric layered architecture of NGNs

Development towards Multimedia Service Delivery

Development towards Multimedia Service Delivery

Converged Service Delivery - Service Delivery Platforms (SDP), Fixed Mobile Convergence (FMC)

Common Service Control – IP Multimedia Subsystem (IMS)

All IP Transport

QoS enabled high bandwidth access technologies – mobile WiMAX, LTE

Access network evolution

Developments in mobile access technologiesEvolved HSPA/HSPA+ enhancement (MIMO and 64 QAM modulation 42 Mbps on single 5 MHz carrier)

Evolved Packet System (EPS) – QoS and Bearer concepts

OFDM based technology - UTRAN Long Term Evolution (LTE), mobile WiMAX

Increase in per user data

rates

Mobile Broadband

Increase consumption of

multimedia services

Access network evolution


8

Development of fixed access technologiesDevelopments in ADSL and VDSL technologyDeployment of FTTx networks (FTTU - Fiber to the user)

Increase in per user

data rates

Ability to offer high data rate services

NGN and triple play

offers

More user data rates than wireless

technology

Transport Technology Evolution


9

Transport layer evolving from ATM / FR to IP

Increasing intelligence in the transport layerEnhanced security

QoS guarantee and enforcement capabilities

Flow based charging of differentiated services

Deep packet inspection capabilities

Service aware bandwidth management

Inter-operator connectivity evolving toward all IP transport

IPX (GSMA initiative) – End to end QoS guarantee allows carrier grade services on IP networks

Increase in significance of Session Border Controllers (SBCs) – Provides security, topology hiding and interworking between signalling protocols

Transport Technology Evolution

Core Network EvolutionIP Multimedia Subsystem


11

Access agnostic core network

Standardized environment for operators to manage IP Multimedia communication sessions – e.g. Voice, Messaging, Sharing

Based on Session Initiation Protocol (SIP)

Approach to cost effective transition towards service centric world

Converged IMS Vision


12

Service Delivery Evolution

Service Delivery Platform (SDP)


13

Merging of Telekom, IT and Media industries

Emergence of new services & consumer behavioure

GAP between Services and Telecom Networks

Enterprise & Web Applications

Telecom Networks

Gap

SDP – A framework for service deployment

Seeks to simplify service provision and management Reduce CAPEX and OPEX

Bridges the gap between network and services

No standard reference model Custom solution for an operator

Delivery of triple and quad play solutions

Complements IP Multimedia Subsystem (IMS)

Fixed Mobile Convergence (FMC)

Fixed Mobile Convergence (FMC) – Seamless mobility

between mobile and access networks

FMC is a key driver for IMS

High Bandwidth Mobile NetworksHigh Bandwidth Mobile Networks

High Bandwidth Fixed NetworksHigh Bandwidth Fixed Networks

Voice over IPFixed Mobile Convergence

IMS

“One number” concept – A single number for fixed,

mobile and soft phones

Hosted IP PBX services – call groups, call hunting……..

Fixed Mobile Convergence (FMC)


17

Probable path to FMC

Converged ServicesWhat’s in it for consumers……………..?Multimedia services any time any where

independent of access technology !

Looking into the future……….

Telcos are becoming ‘bit pipe’ providers

War of the worlds – Telco world vs. Internet world

New services as strategic differentiator

Legacy service delivery – inefficient and expensive
