ITU-T SG19 Structure
SG 19 would not create Working Parties but would
simply have the five allocated Questions report
directly to the plenary.

• Q1 Service and network capability
• requirements and network architecture
• Q2 Mobility management
• Q3 Identification of existing and evolving
• IMT-2000 systems
• Q4Preparation of a handbook on IMT-2000
• Q5Convergence of evolving IMT-2000
• networks with evolving fixed networks

Key Results of Q.1

• Q.1 Service and network capability requirements
  and network architecture
• Key results
• The meeting agreed to support moving network
  function on the Systems Beyond IMT-2000 based on
  the contributions and discussions at the meeting.
  
• The draft Recommendation Q.FNAB version 4.0 was
  developed to include the above function and other
  modification.
• Its completion date is postponed from 4Q 2005 to
  3Q 2006 because the current draft is not mature
  for proposed to AAP Consent at next SG19 meeting.

Key Results of Q.2

• Q2 Mobility management
• Key result
• The draft Q.MMR was enhanced in the areas of
  mobility management features and the requirements
  for inter-CN and inter-AN and intra-AN mobility
  management. A requirement was added on support of
  private IP address domains. Mobility definitions
  have been harmonized with Q.6/13.
• The draft Q.MMF was enhanced in the areas of
  Location Update, Registration, Query and Reply. A
  new section was added on Paging Management.
