1. Scope and ToR
 Make common understanding of what is next step
  Beyond IP                Target Time
  Continue with IP
 Try to sketch it brief as requirements
   Services and Environments
   Horizontal and Vertical views
 Find contribution area and work items
   Standard areas
   Other SDOs
 Role of ITU-T and SG 13
