2A 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
3Definitions
- 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.
4Wireless Internet
5Group 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
6Questions 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.

- Workshop on "Next Generation Networks What, When
and How?"Geneva, 9-10 July 2003 - Joint Rapporteurs Group on NGN (JRG-NGN)
25Joint Rapporteurs Group on NGN (JRG-NGN)
- 4 meetings held in last 10 months
- - last meeting in June 04
- 11 Recommendations under development
- 2 mailing lists open to non-ITU-T members
26What 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
27The 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
28When 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
29How 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
30Recommended follow-up Actions
