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

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
Colombo, Sri Lanka, 7-10 April 2009

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

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

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
