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-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

6
NGN layered Architecture

• 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

• 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
Ability to offer high data rate services
NGN and triple play offers
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

• 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

12
Converged IMS Vision
13
Service Delivery Evolution

• Service Delivery Platform (SDP)

14
Service Delivery Platform (SDP)

• 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)

Service Delivery Platform
15
Service Delivery Platform (SDP)

• 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

• Whats in it for consumers..?

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
