Title: Mobility, 3G and Beyond and NGN


1
Mobility, 3G and Beyond and NGN
  • Tatiana Kurakova,
  • Telecommunication Standardization Sector
  • Engineer
  • 24 June 2004, Victoria Falls, Zimbabwe

2
A View of Terminal Mobility Versus Personal
Mobility
  • Terminal mobility
  • must carry a wireless terminal
  • must be within radio coverage

Network wireless
  • Personal mobility
  • need not carry a terminal
  • must have a personal number

Network wireline
3
Definitions
  • Mobility is the ability to provide services
    irrespective of environment changes that may
    occur by mobile user/terminal/network's
    activities.
  • Personal mobility is the ability of a user to
    access telecommunication services at any terminal
    on the basis of a personal identifier, and the
    capability of the network to provide those
    services delineated in the user's service
    profile.
  • Terminal mobility is the ability of a terminal to
    access telecommunication services from different
    locations and while in motion, and the capability
    of the network to identify and locate that
    terminal.

Wireless Internet

Group on IMT-2000 and Beyond
  • Why mobile studies are so important?
  • growth of wireless access outstripping
    traditional access
  • soon will be over 50 of all subscribers
  • already the case in some markets
  • explosive growth of the Internet
  • strong correlation between wireless access and
    internet usage leads to Wireless Internet
  • multiple forums working on 3G systems
  • need to promote harmonization and convergence
  • rapidly increasing importance of globalization

6
Questions under study (1 of 3)
  • 1) Service and Network capability
    requirements and network architecture
  •      establish a clear vision for future mobile
    services and network capability requirements for
    beyond IMT-2000 systems
  •   2) NNI mobility management protocol (Stage
    3)
  • define new mobility management signalling
    application protocols, or enhancements to
    existing protocols, needed to support IMT-2000
    services to enable global roaming between
    different IMT-2000 family systems.
  •   3) Identification of existing and evolving
    IMT-2000 Systems
  •     identify architectures, detailed
    specifications and releases which have been and
    will be produced by recognized SDOs which make
    up existing and evolving IMT-2000 systems.

Questions under study (2 of 3)

4) Interworking functions to be used with
existing and evolving IMT-2000 systems identify
(and define if not done elsewhere) interworking

26
What is NGN ?
  • A full (carrier class and business class) service
    network
  • Telephony and other Legacy (including Internet
    access) services
  • Data, including High speed access to Internet and
    its applications
  • Video (VOD, Streaming)
  • Digital TV Broadcast, Multimedia (combining all
    of the above)
  • Mobility and Nomadism. Interworking with Legacy
    services for Human and Machine users (including
    RFIDs machines)
  • Network features and technical characteristics
  • Packet-based (IP, MPLS, ATM, Ethernet) transport
  • IP and service intelligence, in an IP-managed
    network
  • Distributed, transport-resource-session-service
    independent control
  • Using IP-friendly (well defined profile) protocols

27
The Transformed Network
  • Always on
  • Anytime, anywhere and in any form
  • Voice and multimedia
  • Self service, intuitive
  • Simple for the end user
  • Secure, trusted and reliable

28
When is NGN coming in ?
  • Some (pre-NGN) pieces are already there
  • PSTN (VoIP, VoATM) trunking, some VoIP offers
  • Private/corporate network solutions (Centrex IP,
    IP VPN)
  • A long way to the 21st Network. Convergence of
    Telephony and Data (IT, Internet) approaches
  • PSTN/ISDN evolving towards NGN oriented platforms
  • Replacement of obsolete PSTN/ISDN network
    elements 2005 onwards
  • Packet Data networks evolution (Fixed-Internet
    convergence)
  • Evolving from the current High Speed Internet
    access (ADSL, WLAN ) platforms
  • To offer new generation Services 2005 onwards
  • Mobile convergence (IMS) 2006 onwards

29
How will NGN be developed and deployed ?
  • Replacing progressively legacy PSTN
    elements/areas
  • Only when becoming obsolete (too little
    OPEX/CAPEX gain, particularly in Core)
  • Migration of PSTN-gtNGN might accelerate after
    2010 (PSTN lines moved to DSLAMs -gt VoIP)
  • Green field deployment (today)
  • Overlay deployment, building over xDSL and
    Fiber-based access to Internet
  • ADSL is being deployed fast, with huge
    investments
  • Opportunity to provide new (audio-data-video)
    services
  • Convergence between Fixed-Mobile and Internet
    services/applications
  • Nomadicity (Mobility Management for Roaming)
  • Mobility through Fixed WLAN (spectrum from Fixed
    -gtNomadic-gtMobile)
  • Harmonizing/Converging with Mobile IMS and
    IP-Cable

30
Recommended follow-up Actions
