Multimedia Service Delivery on Next Generation Networks

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

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. 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. 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

5. Why NGN? • ITU definition - A Next Generation Network is a, • packet-basednetwork 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

6. NGN – layered Architecture 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 • Generic layered architecture of NGNs

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 More user data rates than wireless technology Increase in per user data rates Ability to offer high data rate services NGN and triple play offers • Development of fixed access technologies • Developments in ADSL and VDSL technology • Deployment of FTTx networks (FTTU - Fiber to the user)

9. 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

10. 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 • Increase in significance of Session Border Controllers (SBCs) – Provides security, topology hiding and interworking between signalling protocols Source: GSMA

11. Core Network Evolution • 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 • IP Multimedia Subsystem

12. Converged IMS Vision

13. Service Delivery Evolution Emergence of new services & consumer behavioure Enterprise & Web Applications Gap Merging of Telekom, IT and Media industries Telecom Networks GAP between Services and Telecom Networks • Service Delivery Platform (SDP)

14. Service Delivery Platform (SDP) Enterprise & Web Applications Service Delivery Platform Telecom Networks 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)

15. Service Delivery Platform (SDP) Core Network • Sample SDP deployment

16. 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 Fixed Mobile Convergence Voice over IP High Bandwidth Fixed Networks • “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) • Probable path to FMC

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

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

21. ThANK YOU!
