Current Service Delivery Landscape
Developments in access
network technology
e.g. mobile – HSPA,
HSPA+, WiMAX, LTE high
bandwidth transport
Telco Operators Bit pipe providers
Expanding competitive
landscape
Increased competition
Internet based services

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
Colombo, Sri Lanka, 7-10 April 2009

NGN – layered Architecture
Generic layered architecture of NGNs
NGN Layer
Application Layer
Network Layer
Transport Layer
Access Layer
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 technologies
Evolved 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
Development of fixed access technologies
Developments in ADSL and VDSL technology
Deployment of FTTx networks (FTTU - Fiber to the user)
More user data
rates than
wireless
technology
Increase in
per user
data rates
Colombo, Sri Lanka, 7-10 April 2009
Ability to
offer high
data rate
services
NGN and
triple play
offers

Transport Technology Evolution
Transport layer evolving from ATM / FR to IP
Increasing intelligence in the transport layer
Enhanced security
QoS guarantee and enforcement capabilities
Flow based charging of differentiated services
Deep packet inspection capabilities
Service aware bandwidth management
Colombo, Sri Lanka, 7-10 April 2009
9
Transport Technology Evolution
Inter-operator connectivity evolving toward all IP transport
IPX (GSMA initiative) – End to end QoS guarantee allows
carrier grade services on IP networks
Source: GSMA
Increase in significance of Session Border Controllers
(SBCs) – Provides security, topology hiding and
interworking between signalling protocols
Colombo, Sri Lanka, 7-10 April 2009
10
Core Network Evolution
IP Multimedia Subsystem
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
Colombo, Sri Lanka, 7-10 April 2009

Service Delivery Evolution
Service Delivery Platform (SDP)
Enterprise & Web Applications
Merging of Telekom, IT and
Media industries
Gap
Telecom Networks
Emergence of new services &
consumer behavioure
Colombo, Sri Lanka, 7-10 April 2009
GAP between Services and
Telecom Networks

Service Delivery Platform (SDP)
SDP – A framework for service
deployment
Enterprise & Web Applications
Service Delivery Platform
Telecom Networks
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
IMS
High Bandwidth
Mobile Networks
Voice over IP
Fixed Mobile
