Third Generation Mobile Systems

• IMT-2000 concept developed in the ITU
• IMT-2000 is the ITU term used in a set of ITU
  Recommendations which describe International
  Mobile Telecommunications-2000
• a fundamental concept behind IMT-2000 is to
  provide users with communications anywhere,
  anytime
• 3G Partnership Projects
• co-ordinate development of detailed
  regional/national specifications
• 3rd Generation Partnership Project - 3GPP
• SDO partners are ARIB, CWTS, ETSI, T1, TTA, TTC
• development of GSM evolved UMTS core network with
  UTRAN access network
• Third Generation Partnership Project 2 - 3GPP2
• SDO partners are ARIB, CWTS, TIA, TTA, TTC
• development of ANSI-41 evolved core network with
  cdma2000 access network

Q.6/SSG - Harmonization of Evolving IMT-2000
Systems

• Question 6/SSG asks
• What is needed for harmonization of evolving
  IMT-2000 systems?
• To provide seamless global roaming for IMT-2000
  future Capability Set services that will include
• voice,
• high speed packet data,
• multimedia, and
• IP-based services,
• what are the network solutions that would
  facilitate harmonization of evolving IMT-2000
  systems?

Q.6/SSG - Harmonization of Evolving IMT-2000
Systems

• Q.6/SSG task objectives include
• establish co-operative relationships- within ITU
  (ITU-T, ITU-R, ITU-D)- externally with other
  SDOs, etc.
• study existing IMT-2000 systems
• identify gaps/areas for harmonization
• develop proposals to facilitate harmonization
• document results

Basic goal of harmonization activity
development of common network solutions based on
standardized open interfaces in order to -
facilitate cost-effective IMT-2000 network
deployments - stimulate the commercial uptake
of IMT-2000 services, and - foster global
roaming across all evolving IMT-2000 systems.

  IMT-2000 Systems - Rapporteur Frédéric Delmond
  (France Telecom)
• Question 2/SSGNNI Mobility Management Protocol
  (Stage 3)- Rapporteur Jean-Claude Samou (France
  Telecom)

Other presentations today will address Study
Questions Q.2/SSG and Q.7/SSG in greater detail.
7
Related SSG Questions (continued)

• Question 3/SSG Identification of existing and
  evolving IMT-2000 systems -
  Rapporteur Ilkka Hyvärinen (Nokia Networks,
  Finland)
• Rec. Q.1741.1 IMT-2000 References to Release
  1999 of GSM evolved UMTS Core Network with
  UTRAN Access Network
• Rec. Q.1741.2 IMT-2000 References to Release
  4 of GSM evolved UMTS Core Network with UTRAN
  Access Network
• Rec. Q.1742.1 IMT-2000 References to ANSI-41
  evolved Core Network with cdma2000 Access
  Network

Draft Recommendations approval anticipated by
year end 2002.
8
Related SSG Questions (continued)

• Question 1/SSG Service and network capability
  requirements and network architecture
  - Rapporteur Ed Chien (USA)
• Rec. Q.1702 Long-Term Vision of Network
  Aspects for Systems Beyond IMT-2000
• Question 5/SSG To participate in the preparation
  of a Handbook on IMT-2000 - Rapporteur
  Maurice Ghazal (Lebanon)
• Q.5/SSG is contributing to the network aspects
  component of the emerging Handbook.
• Question 4/SSG Interworking functions to be used
  with existing and evolving IMT-2000
  systems There has been little progress on
  interworking under Q.4/SSG, partly because of
  the lack of a Rapporteur.

Outline

• Harmonization studies in the SSG
• Linkages with other bodies - Collaboration
  within ITU - Linkages outside ITU
• Current status of Q.6/SSG activity
• Next steps

10
Linkages on Harmonization outside ITU

• Formal Standards Development Organizations (SDOs)
• formal standards are being referenced through
  SDOs (TIA, ETSI, TTA, etc)
• existing relationships with ITU is effective
• 3G Partnership Projects (3GPP and 3GPP2)
• for both 3GPP and 3GPP2 an established
  relationship exists at the SSG level through the
  SSG Chairman
• relationships are being developed at the working
  level
• Internet Engineering Task Force (IETF)
• SSG studies may identify new/modified protocol
  requirements
• possible future interaction with IETF on protocol
  requirements

11
Collaboration within ITU

• ITU-T
• SG-13 Interaction to ensure consistency with
  areas under SG-13 responsibility such as NGN
  (Information sharing in Geneva, November 2002)
• SG-11 Similar synergy on NGN studies (There was
  discussion at the SSGs Ottawa meeting in May
  2002, and a Liaison Statement to SG-11 from
  Q.7/SSG addressed mobility across fixed and
  mobile networks)
• SG-16 Interaction on Multimedia aspects of
  mobility studies
• SG-12 future interaction likely on
  Quality-of-Service aspects
• SG-2 possible collaboration in areas such as
  - Numbering/Addressing and Identities -
  Service descriptions for mobile services (stage
  1)

12
Collaboration within ITU (continued)

• ITU-D
• Coupling through Q.5/SSG on IMT-2000 Handbook
• Some direct interaction anticipated
• ITU-R
• ITU-R WP 8F work provides basic background for
  existing systems(e.g., ITU-R Rec. M.1457
  Detailed Specifications of the Radio Interfaces
  of International Mobile Telecommunications-2000
  (IMT-2000))
• it also provides insight into longer-term
  Vision (for which an indirect coupling exists
  through Q.1/SSG which studies Service and
  network capability requirements and network
  architecture)

• Draft is entitled Harmonization of Evolving
  IMT-2000 Systems
• Recently progressed at Joint Rapporteurs'
  Meeting (JRM)(9-13 September 2002 in Seoul
  (Korea))
• Anticipated completion in early 2003
• Current contents include
• Needs and opportunity for harmonization
• Background on architectures of evolving IMT-2000
  systems
• survey of related IETF work
• identification of commonalities and differences

Note The report of the JRM in Seoul and the
draft Q.6/SSG output document are contained inTD
14 (WP 3/SSG) and TD 13 (WP 3/SSG) at the SSG
meeting in Geneva, November 2002. Other Seoul

• The draft Q.6/SSG output document will be
  reviewed during this weeks SSG meeting in
  Geneva.
