1. Colombo, Sri Lanka, 7-10 April 2009 Multimedia Service Delivery on Next Generation Networks Pradeep De Almeida, Group Chief Technology Officer Dialog Telekom PLC FORUM ON NEXT GENERATION STANDARDIZATION (Colombo, Sri Lanka, 7-10 April 2009)

2. Colombo, Sri Lanka, 7-10 April 2009 2 Contents 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. Colombo, Sri Lanka, 7-10 April 2009 3 Current Service Delivery Landscape Developments in access network technology e.g. mobile – HSPA, HSPA+, WiMAX, LTE  high bandwidth transport Expanding competitive landscape Increased competition Internet based services Telco Operators  Bit pipe providers

4. Colombo, Sri Lanka, 7-10 April 2009 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 Application 1 Management Service Capability Integration Application 2 Management Service Capability Integration Application 3 Management Service Capability Integration Vertical Silos in service deployment

5. 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 5

6. NGN – layered Architecture NGN LayerApplication LayerNetwork LayerTransport LayerAccess Layer Generic layered architecture of NGNs 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

7. 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

8. Access network evolution Colombo, Sri Lanka, 7-10 April 2009 8 Development of fixed access technologies Developments in ADSL and VDSL technology Deployment 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

9. Transport Technology Evolution Colombo, Sri Lanka, 7-10 April 2009 9 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

10. 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 Source: GSMA 10 Colombo, Sri Lanka, 7-10 April 2009

11. Core Network Evolution IP Multimedia Subsystem Colombo, Sri Lanka, 7-10 April 2009 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

12. Converged IMS Vision Colombo, Sri Lanka, 7-10 April 2009 12

13. Service Delivery Evolution Service Delivery Platform (SDP) Colombo, Sri Lanka, 7-10 April 2009 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

14. 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) Colombo, Sri Lanka, 7-10 April 2009 14 Service Delivery Platform (SDP) Enterprise & Web Applications Telecom Networks Service Delivery Platform

15. Service Delivery Platform (SDP) Colombo, Sri Lanka, 7-10 April 2009 15 Sample SDP deployment Core Network

16. Colombo, Sri Lanka, 7-10 April 2009 16 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 Networks High Bandwidth Fixed Networks Voice over IP Fixed Mobile Convergence IMS “One number” concept – A single number for fixed, mobile and soft phones Hosted IP PBX services – call groups, call hunting……..

17. Fixed Mobile Convergence (FMC) Colombo, Sri Lanka, 7-10 April 2009 17 Probable path to FMC

18. Converged Services What’s in it for consumers……………..? Multimedia services any time any where independent of access technology ! Presence Instant Messaging Content Sharing Interactive Gaming Video Sharing Push to X Services Next Generation Networks Location Services Multimedia Experience Seamless Mobility Security & Personalization

19. NGN implementation challenges Availability of end user devices SIP supported mobile handsets Complexity of new services E.g. SMS vs. MMS Suitable regulatory framework Fixed mobile convergence NGN technology – must generate ROI Business models for new services Colombo, Sri Lanka, 7-10 April 2009 19

20. Colombo, Sri Lanka, 7-10 April 2009 20 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 Next Generation Networks
