Prakash and All, 
   
  As you knew, all contributions related to backbone 
  messages were remanded to NETMAN at the last meeting.
  However, NETMAN SG may be re-established as 802.16g 
  with its timeline 2006/2007. 
   
  If then, the current HO procedure with the aid of 
  backbone messages may be de-facto standard till NETMAN's time schedule. 
  
   
  Accordingly, I think that Handover AdHoc Group will 
  discuss the backbone messages together for advanced handover procedure. 
  
   
   
  Thanks,
