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 Colombo, Sri Lanka, 7 -10 April 2009

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……. Colombo, Sri Lanka, 7 -10 April 2009 2

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

Service delivery challenges on legacy networks Service deployment time (Time To Market) – competitive edge High Capex and Opex on new services – vertical silos Application 1 Application 2 Application 3 Management Service Capability Integration Vertical Silos in service deployment Deployment of advanced & Value Added Services Strategic differentiation from internet based services Quality of Service (Operator VOIP vs. Skype) Security Colombo, Sri Lanka, 7 -10 April 2009 4

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 Qo. S-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

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 Qo. S enabled high bandwidth access technologies – mobile Wi. MAX, 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) – Qo. S and Bearer concepts OFDM based technology - UTRAN Long Term Evolution (LTE), mobile Wi. MAX 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 8

Transport Technology Evolution Transport layer evolving from ATM / FR to IP Increasing intelligence in the transport layer Enhanced security Qo. S 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 Qo. S 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 11

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

Service Delivery Evolution Service Delivery Platform (SDP) Media Telecom IT 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 13

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) Colombo, Sri Lanka, 7 -10 April 2009 14

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

Fixed Mobile Convergence (FMC) – Seamless mobility between mobile and access networks FMC is a key driver for IMS High Bandwidth Mobile Networks Voice over IP Fixed Mobile Convergence High Bandwidth Fixed Networks “One number” concept – A single number for fixed, mobile and soft phones Hosted IP PBX services – call groups, call hunting……. . Colombo, Sri Lanka, 7 -10 April 2009 16

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

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

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

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 Colombo, Sri Lanka, 7 -10 April 2009 20
